Great watches the transformation the necessity

 From on macroscopic looked that, the industry developed country armed forces, the airplane weapon industry, in the end of the 70's, at the beginning of the 80's started the large-scale application numerical control engine bed. Its essence is, uses the information technology to the traditional industry (including the armed forces, airplane weapon industry) carries on the technological transformations. Except that uses outside the numerical control engine bed, FMC, FMS in the manufacture process, but also includes in the product development carries out CAD, CAE, CAM, the hypothesized manufacture as well as carries out MIS in the production management (management information system), Cnc machining CIMS and so on. As well as increases the information technology in its production product, including artificial intelligence and so on content. Because uses the information technology to the country foreign troops, the airplane weapon industry carries on the thorough transformation (to call it becoming an information based society), finally causes them the product in the international military goods and in the goods for civilian use market the competitive power greatly is the enhancement. But we in the information technology transformation tradition industry aspect compared to the developed country to fall behind approximately for 20 years. Like in our country engine bed capacity, numerical control engine bed proportion (numerical control rate) to 1995 only then 1.9%, but Japan has reached 20.8% in 1994, therefore every year has the massive mechanical and electrical products import. This also on from on macroscopic explained the engine bed numerical control transformation necessity

 Transformation industry starting

   In US, Japan and Germany and so on the developed country, their engine bed transforms took the new economical growth profession, thrives abundantly, is occupying the golden age. As a result of the engine bed as well as the technical unceasing progress, Cnc machining the engine bed transformation is "the eternal" topic. Our country's engine bed transformation industry, also enters from the old profession to by the numerical control technology primarily new profession. In US, Japan, Germany, have the broad market with the numerical control technological transformations engine bed and the production line, has formed the engine bed and the production line numerical control transformation new profession.

Is engaged in the reequipment industry famous company to include: Big indentation project group, hillock three mechanical companies, thousand substitute fields labor machine company, wild  engineering firm, shore field engineering firm, mountain this engineering firm and so on

 Numerical control transformation content

   The engine bed and the production line numerical control transformation main content has following several points:

   First is extensively recovers the function, to the engine bed, theproduction line has the breakdown partially to carry on the diagnosis and the restoration;      

 Second is NC, the addend reveals the installment on the ordinary engine bed, or adds the numerical control system, transforms the NC engine bed, the CNC engine bed;   

    Third is renovates, for increases the precision, the efficiency and the automaticity, to the machinery, the electricity partially carries on renovates, reassembles the processing to the machine part, extensively recovers the precision; Does not satisfy the production request to it the CNC system to carry on the renewal by newest CNC;    

   Fourth is the technology renews or the technical innovation, for enhances the performance or the scale, or in order to use the new craft, the new technology, carries on the big scale in the original foundation the technology to renew or the technical innovation, the great scope raises the level and the scale renewal transformation.   

 The new electrical system transforms after, how carries on the debugging as well as the determination reasonable approval standard, also is the technology preparatory work important link. The debugging work involves the machinery, the hydraulic pressure, the electricity, the control, and so on, therefore must carry on by the project person in charge, Cnc machining other personnel coordinate. The debugging step may conform to simplicity to numerous, from infancy to maturity, carries on from outside to in, after also may the partial overall situation, after first the subsystem the.

Engine bed numerical control transformation necessity

Engine bed numerical control transformation necessity 

 microscopic looks at the transformation the necessity    

From on microscopic looked below that, Cnc machining the numerical control engine bed has the prominent superiority compared to the traditional engine bed, moreover these superiority come from the computer might which the numerical control system contains

 May process the traditional engine bed cannot process the curve, the curved surface and so on the complex components.

  Because the computer has the excellent operation ability, may the instant accurately calculate each coordinate axis instant to be supposed the movement physiological load of exercise, therefore may turn round thesynthesis complex curve or the curved surface.

  may realize the processing automation, moreover is the flexible automation, thus the efficiency may enhance 3 ~ 7 times compared to the traditional engine bed

 Because the computer has the memory and the memory property, may the procedure which inputs remember and save, then Cnc machining the order which stipulated according to the procedure automatic carries out, thus realization automation. The numerical control engine bed so long as replaces a procedure, may realize another work piece processing automation, thus causes the single unit and the small batch of production can automate, therefore is called has realized "flexible automation

  Processings components precision high, size dispersion degree small, makes the assembly to be easy, no longer needs "to make repairs".

  May realize the multi- working procedures centralism, reduces the components in engine bed between frequent transporting.  

  Has auto-alarm, the automatic monitoring, automatic compensation and so on the many kinds of autonomy function, thus may realize long time nobody to safeguard the processing. 

  Advantage which derives by above five.

   For example: Reduced worker's labor intensity, saved the labor force (a person to be possible to safeguard the multi- Taiwan engine bed), reduced the work clothes, reduced the new product trial manufacturing cycle and the production cycle, might to the market demand make rapid reaction and so on. 

  Above these superiority are the predecessor cannot imagine, is an extremely significant breakthrough. In addition, Cnc machining the engine bed numerical control carries out FMC (flexible manufacture unit), FMS (flexible manufacture system) as well as CIMS (computer integration manufacture system) and so on the enterprise becoming an information based society  transformation foundation. The numerical control technology already became the manufacturing industry automation the core technology and the foundation technology

The comprehensive impetus electric spark development direction

The comprehensive impetus electric spark development direction

For the comprehensive impetus electric spark forming processing equipment technology advancement, while uses the advanced control system, the engine bed structure design also needs further to consummate, its main development direction displays in following two aspects: (1) straight line servosystem application

 Precision wire cutting The electric spark forming processing equipment uses the straight line electrical machinery servosystem to be possible to cause the workability to obtain the distinct improvement, the concrete manifestation is:  May realize the axis direct translation, omits a guide screw nut transmission link, thus guarantee axis high speed movement;  Uses the straight line electrical machinery and the slide integration structure, may eliminate between the slide and the electrical machinery because of has the machinery lag in response phenomenon which the middle link causes, enhances the system the sensitivity, reduces the dynamic response time, the guarantee processing process stability;  The straight line electrical machinery servosystem mode of motion had decided its position examination link must use the straight line position feedback part, the realization not middle link direct position examination, thus constitutes an entire closed-loop system, the guarantee processing process high accuracy and the precision retentivity. At present, the straight line servosystem application in deep narrow, the small die space processing and a mould pressing components mold multi-cavity processing aspect has the obvious technical superiority. But, these technical superiority must realize truly, except must unify the electric spark forming processing electric discharge process characteristic, outside the solution straight line servosystem itself technical difficult problem, but also must solve a series of and the straight line servosystem necessary related technology, like translation system dynamic equilibrium, work table structure improvement and so on.

 (2) engine bed mode of motion improvement

 Precision wire cutting Breaks through the existing electric spark forming processing engine bed mode of motion the limitation, is displays its technical superiority, impels its industrial development another important way. The model modern machining technology development experience, may direct the human circular motion in the engine bed main processing forming movement foundation, specially uses the multiple spindle rotary system and many kinds of translation coordinating group synthesizes many kinds of compound motion way, adapts the different type work piece processing request, the expanded electric spark forming processing processing scope, enhances it in the precise processing aspect comparison superiority and the technical benefit. At present, many electric spark forming processing engine bed has made some improvements in the mode of motion, if Swiss Arch Company produces AGIF the MONDO STAR20(50) engine bed has the EQUIMODE function, can realize the spatial any direction hemisphere stable motion, this kind of stable motion function has the very high practical value in the actual processing. But the present electric spark forming processing engine bed additionally builds the mode of motion is also unitary, the application scope is limited. The electric spark forming processing must in aspects and so on processing precision, processing efficiency, processing scope obtain the significant breakthrough, an important development direction is to the engine bed forming mode of motion innovation and the diversification. Recently, Japan University of Tokyo -odd component doctor, increased Ze prosperous long Professor and so on to propose loss concepts and so on electrode, namely through to processed the way the reasonable plan, might cause the electrode to lose is at and so on the loss conditions, thus caused the compensation which the electrode lost to become extremely simple. This concept statement has provided the essential theory basis for the electric spark forming processing mode of motion improvement. Certainly, produces from this the engine bed structural change and the correlation technology theory research also must further the deep person and the consummation, even has the possibility to develop one kind of brand-new processing theory.

  Precision wire cutting In addition, the engine bed overall construction design must consider fully the environmental protection as well as a human machine coordination, with the aid of the advanced design method and the method (for example CAD, the finite element analysis and so on) carry on the comprehensive optimized design to the engine bed structure, enhances the engine bed structure fully the sophistication and the rationality.

The development trend of manipulator

The development trend of manipulator   

  Current industrial applications of the manipulator gradually expanding, cnc machining parts constantly improve the technology performance. Due to the short development time, it has a gradual understanding of process, the manipulator and a technically perfect step by step process, its development trend is

  1、To expand the application of manipulator and processing industry   

At present domestic robots used in mechanical industry more in cold working operations, while in the hot work such as casting, forging, welding, heat treatment less, and the application of assembly work, etc. So processing work items heavy, complicated shape and high environmental temperature, bring many difficulties to manipulator design, manufacture, cnc machining parts it is need to solve the technical difficulties, make the manipulator to better service for processing work. At the same time, in other industries and industrial sectors, also will with the constant improvement of the industrial technology level, and gradually expand the use of the manipulator 

2、Improve the work performance of the industry manipulator    

Manipulator in the working performance of the pros and cons,determines the application and production, cnc machining parts it can normal manipulator working performance of the repetitive positioning accuracy and speed of work two indicators, decided to ensure the quality of manipulator can complete the operation of the key factors. Therefore to solve good working stability and rapidity of the manipulator's request, besides from solve buffer localization measures, should also be development meet the requirements of mechanical properties and low price of electro-hydraulic servo valve, servo control system was applied to the mechanical hand.

General transformation of multi-axis drilling machine drilling machin

General transformation of multi-axis drilling  machine drilling machin 

Cnc milling machine small and medium enterprises in product quality and  production efficiency are the need for a new increase. But the processing means is far from sufficient. Many small and medium enterprises with their actual technical state of equipment improvements, through strengthening its own. In order to self-development.Common drilling for single-axis machine tools, but the installation will become a multi-axis multi-axle box of the drill, transformation into a multi-axis drilling, we could greatly shorten the processing time, improve production efficiency.            

   Application of multi-axis machining ：

 Cnc milling machine According to statistics, in general machine  tools in the workshop in general, the average cutting time rarely exceeds 15% of total working hours. The remaining time is plug-in, loading and unloading the workpiece, exchange tools, operation tools, measurements, and clear the iron filings and so forth. Although the use of CNC machine tools can improve 85%, but the purchase of costly. In some cases, even if the high productivity, but the processing of the same components, the cost is not necessarily lower than the average machine. Therefore must be more to shorten the processing time. Different processing methods have different characteristics, the drilling process, the multi-axis machining is a small investment to increase productivity through effective measures. 

The advantages of multi-axis machining ：

Although it is not the first in automatic  multi-axis adjustable long line applications, but only limited to high-volume production. Even with the adjustable multi-axis head expanded the scope of use is still far from being able to meet the volume is small, hole complex requirements. In particular, as industrial development, large and complex multi-axis machining is even more compelling. For example, large-scale nuclear power plants in the water-wall tube plate condenser has 15000 ψ20 holes, if radial drilling machine processing, and simply drilling holes and countersink countersunk head is necessary to 842.5 hours, while also crossed hours 151.1 hours. However, if the 8-axis CNC machining floor drilling, drilling countersink holes as long as 171.6 hours, crossed is also simple, as long as 1.9 hours. Therefore, the use of numerical control of two axis, so that proper alignment tool processing location, combined with multi-axis machining can not only expand the range of processing, but also on the basis of improving the accuracy can greatly enhance the work efficiency, easy to quickly create original processing parts. Some analysis of large high-speed diesel engine with 30 kinds of box-shaped rod-shaped parts of the more than 2,000 drilling operations, 40% could be the automatic replacement of machines using two-axis spindle box, three-axis or four-axis multi-axis machining head, the average can be reduced 20% of the processing time. Machine Tool Exhibition in Paris in 1975 also reflected the multi-axis machining using more and more the trend.   

Multi-axis machining equipment ：

 Cnc milling machine  Multi-axis machining is the same time in a feed  processing a number of holes or simultaneously in many of the same or different processing of a workpiece on each hole. This will not only shorten the cutting time and improve accuracy, reduce fixturing or positioning time, and in the CNC machine tool is not necessary to calculate the coordinates, reducing the number of character blocks

and simplified programming. It can be processed using the following equipment: radial drillingvertical drilling, or upload multi-axis head, multi-axis drilling machine, multi-axis modular machine tool spindle box heart and automatic replacement of machines. May even be able to automatically adjust wheelbase by two or more of the spindle axle box, junction  All CNC vertical and horizontal table two directions of movement, processing a variety of round or oval-shaped hole group of one or several steps. Now the status quo in this regard to make a profile。

The composition of clamping devices

The composition of clamping devices

 Precision CNC machining parts In the machining process the work piece by the cutting force, centrifugal force, inertia  force, such as the role of, in order to ensure that these external force, the workpiece can remain in the fixture by the positioning of the processing to determine the location of components, and should be no vibration or displacement, fixture structure should be set up reliable work piece clamping device folder will be in prison.

  First, the composition of clamping devices  

   Many different types of clamping devices, but their structures are composed of two parts.

  1.  Precision CNC machining parts Power plant The source of clamping force, one human; second is generated by a power device.The device can generate power as the power unit fixture. Commonly used in power plant are: pneumatic devices hydraulic devices electrical devices electromagnetic devices gas - liquid interaction devices and vacuum devices. Fixture as a result of manual clamping force from the human so it does not power plants.

  2. Clamping part 

    Receive and impart into the original clamping force to clamp the task force and part of the implementation of the general composition of the following agencies:      

1) to accept the original force of bodies. Such as handles nuts and used to connect the institutions such as cylinder piston rod.  

   2)  Precision CNC machining parts Force the middle of delivery. Such as hinges

 levers and so on.  

   Force delivery of them in the middle of the original transmission of force to the process of clamping devices can play such as changes in the direction of force to change the size of forces as well as the role of self-locking and so on.

  3) Clamping components. Such as plate such as screws.
