Skids the guide screw and the ball bearing guide screw

Skids the guide screw and the ball bearing guide screw     
 The CNC machining parts  guide screw transmission relates directly to the transmission chain precision. The guide screw selects mainly is decided requests and drives the torque request in the job precision. Is  not used by job precision request Gao Shike skids the guide screw, but should inspect the original guide screw attrition situation, like the pitch error and the pitch accumulative error as well as matches the nut gap. The ordinary circumstances skid the guide screw to be supposed not to be lower than 6 levels, the nut gap oversized then replaces the nut. Uses skids the guide screw relative ball bearing guide screw price to be  low, but satisfies the precision high components processing with difficulty
 The ball bearing guide screw rubs loses slightly, the efficiency is high, CNC machining parts  its transmission efficiency may above 90%; Precision high, the life is long; When start moment of force and movement the moment of force approaches, may reduce the electrical machinery to start the moment of force. Therefore may satisfiedly compare the high accuracy components processing request
 Safe protection

  The effect must take the security as a premise. Transforms in the engine bed must take the corresponding measure according to the actual situation, cuts noticeable. CNC machining parts  The ball bearing guide screw vice- is the precision part, when the work must take strict precautions against the dust is specially the scrap and the hard sand grains enters the roller conveyer. On longitudinal guide screw also coca overall sheet iron safety mask.

In the numerical control transformation the main mechanical part reequips the discussion

In the numerical control transformation the main mechanical part reequips the discussion
 A new numerical control engine bed Cnc machining, must achieve in the design that, Has the high static dynamic rigidity; Movement vice- between friction coefficient small, the transmission is ceaseless; The power is big; Is advantageous for the operation and the service. When engine bed numerical control transformation should meet the above requirements as far as possible. Cannot think the numerical control installment and the ordinary engine bed connects in has met the numerical control engine bed requirements together, but also should carry on the corresponding transformation to the major component to enable it to achieve the certain design request, can obtain the anticipated transformation goal
Skids guide rail   
    Cnc machining  Said to the numerical control lathe that, the guide rail besides should have the conventional lathe guidance precision and the technology capability, but also must have good bears the friction, the attrition characteristic, and the reduction but sends the dead area because of the friction drag. At the same time must have the enough rigidity, by reduces the guide rail to distort to processes the precision the influence, must have the reasonable guide rail protection and the lubrication
 Gear  

     Cnc machining The common engine bed gear mainly concentrates in the headstock and the gear box. In order to guarantee the transmission precision, on the numerical control engine bed uses the gear precision class is all higher than the ordinary engine bed. Must be able to achieve the ceaseless transmission in the structure, thus transforms time, the engine bed main gear must satisfy the numerical control engine bed the request, by guarantees the engine bed processing precision

Numerical control system choice

Numerical control system choice 
  When the numerical control system mainly has three kind of types, the transformation, should act according to the special details to carry on the choice
Step-by-steps the open system which the electrical machinery drives   
   This system servo drive mainly is step-by-steps the electrical machinery, the power step-by-steps the electrical machinery, Cncmachining the battery solution pulse motor and so on. Entering sends out which by the numerical control system for instruction pulse, after the actuation electric circuit control and the power enlargement, causes to step-by-step the electrical machinery rotation, through gear vice- and ball bearing guide screw vice- actuation executive component. So long as the control command pulse quantity, the frequency as well as the circular telegram order, then may control the executive component movement the displacement quantity, the speed and the heading. This kind of system does not need the physical location and the velocity feedback which obtains to the input end, therefore called it the open system, this system displacement precision mainly decided in step-by-steps the electrical machinery angular displacement precision, transmission part and so on gear guide screw pitches the precision, therefore the system displacement precision is low.  
  This system structure simple, debugging service convenient, work reliable, cost low, is easy to reequip successfully
 The asynchronous motor or the direct current machine drive, diffraction grating survey feedback closed loop numerical control system 
  This system and the open system difference is: Cncmachining  Physical location feedback signal which by position detector set and so on the diffraction grating, induction synchromesh obtains, carries on the comparison as necessary with the given value, two interpolations enlargements and the transformation, the actuation implementing agency, by the speed which assigns turns towards the elimination deviation the direction movement, until assigns the position and the feedback physical location interpolation is equal to the zero. The closed loop enters for the system  Enters for the system complex in the structure compared to the split-ring, the cost is also high, requests strictly to the environment room temperature. The design and the debugging is all more difficult than the open system. But may obtain compared to the split-ring enters for a system higher precision, quicker speed, actuation power bigger characteristic target. May act according to the product specification, decided whether uses this kind of system
 The direct current servo electrical machinery drives, encoder feedback semi-closure link numerical control system
 Half closed-loop system examination part installs in among passes in the moving parts, indirectly surveys the executive component the position. It only can compensate a system ring circuit interior part of part the error, therefore, its precision compared to closed-loop system precision low, but its structure and the debugging all compares the closed-loop system to be simple. In makes the angular displacement examination part and the speed examination part and the servo electrical machinery time a whole then does not need to consider the position detector set installs the question
  The current production numerical control system Cncmachining  company factory quite are many, overseas famous company like German SIEMENS Corporation,
 Japanese FANUC Corporation; Native corporation like China Mount Everest Corporation, Beijing astronautics engine bed numerical control system group company, Central China numerical control company and Shenyang upscale numerical control country engineering research center. 

  When choice numerical control system mainly is each kind of precision which the engine bed must achieve after the numerical control transformation, actuates the electrical machinery the power and user's request.

The numerical control transformation superiorly lacks

The numerical control transformation superiorly lacks
 Reduced investment costs, the date of delivery are short 
  With purchases the new engine bed to compare, may save 60% ~ 80% expense generally, the transformation expense is low. Large-scale, the special engine bed especially is specially obvious. The common large-scale engine bed transforms, Cnc machining only spends the new engine bed purchase
 expense 1/3, the date of delivery is short. But some peculiar circumstances, like the high speed main axle, the tray automatic switching unit manufacture and the installment too requires a lot of work, costs a great deal of money, often transforms the cost to enhance 2 ~ 3 times, with purchases the new engine bed to compare, only can economical invest about 50%.
   Machine capability stable are reliable, the structure is limited
   Uses foundation and so on lathe bed, column all is heavy but the firm casting component, but is not that kind of welding component, after the transformation engine bed performance high, the quality is good, may take the new equipment continues to use many years. But receives the original mechanism the limit, not suitably makes the unprecedented transformation.
  Familiar understood the equipment, is advantageous for the operation service  
 When purchases the new equipment, did not understand whether the new equipment can satisfy its processing request. Cnc machiningThe transformation then otherwise, may precisely calculate the engine bed the processing ability; Moreover, because many years use, the operator already understood to the engine bed characteristic, uses and services the aspect to train the time in the operation short, effective is quick. The transformation engine bed as soon as installs, may realize the capacity load revolution.
 May fully use the existing condition
  May fully use the existing ground, Cnc machining does not need to like buys when the new equipment such to have reto construct the ground.
  May use the newest control technology 

 enhances the production equipment the automated level and the efficiency, improves the equipment quality and the scale, alters to the old engine bed now the horizontal engine bed.
