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

 A new numerical control engine bed, must achieve in the design that, Has the high static dynamic rigidity; Movement vice- between friction coefficient small, the transmission is ceaseless; cnc milling machine 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      

 Said to the numerical control lathe that, cnc milling machine 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

 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

kids the guide screw and the ball bearing guide screw    

  The 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, 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. 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. The big carriage with skids two end surfaces which the guide rail contacts to have to seal, prevented absolutely the flinty granulated foreign matter enters the sliding surface damage guide rail

 Sixth, After the engine bed electrical system transformation, to  operates, the programmers inevitably brings the new request. Therefore ahead of time carries on new system knowledge training to the operator and the programmers to be extremely important, after otherwise will affect the transformation the engine bed rapid investment production. The training content should include the new operation kneading board disposition, the function, the instruction meaning generally; New system functional scope, application method and with old system difference; Maintenance maintenance request; Programming standard and automated programming and so on.

The key point is makes, gets a good grasp of the operating manual and the programming instruction booklet.  the numerical control transforms se Transforms the scope according to each  equipment differently, must beforehand design the connection partial transformations, if transforms completely, should design the electro-mechanical transformation connection, the operation kneading board control and the disposition, cnc milling machinethe interconnection partial contacts, the parameter measuring point, services the position and so on, the request operates and services conveniently, reasonable, the line moves towards, center the small junction smoothly few, the strong and the weak electrical noise is smallest, has the suitable allowance and so on. Partial transformation, but also needs to consider the new old system the performance match, the voltage polarity and the size transformation, install the position, the digital-analog conversion and so on, when the necessity must manufacture the transformation connection voluntarily.
