CNC lathe processing has been used more and more widely in modern manufacturing,and has taken advantage of the incomparable ordinary lathe.CNC lathe processing mainly has the following characteristics:
1.There are deficiencies in the processing drive chain of CNC lathes.Compared with the ordinary lathe,the spindle drive is no longer the shifting of the motor with the gear pair mechanism.Instead,the two servo motors drive the lateral and longitudinal feed respectively,and the transmission chain is greatly shortened,eliminating the need for conventional components such as a hanging wheel and a clutch.
2,high stiffness,in order to match the high precision of the CNC system,the machining rigidity of the CNC lathe is very high,to meet the high-precision machining requirements.
3,the knife holder(workbench)moves to use the light-drawn ball screw pair,the conflict is small,and the movement is light.The special bearing pressure angle at both ends of the screw is larger than that of the ordinary bearing,and the matching is selected at the factory.The smooth part of the CNC lathe is automatically smoothed by the oil mist,making the machining of the CNC lathe easy to move.
Second,the processing characteristics of CNC lathe
1.High degree of automation,reducing the labor intensity of operators.The machining process of the CNC lathe is done automatically according to the input program.The operator only needs to start the tooling,workpiece loading and unloading,and tool change.In the process of processing,the main task is to investigate and supervise the operation of the lathe.However,due to the highly skilled content of the CNC lathe,the operator's mental work has also been improved accordingly.
2.CNC lathes have high precision and stable quality.The positioning accuracy and repeat positioning accuracy of CNC lathes are very high,and it is easier to ensure the commonality of a batch of parts and scales.Only the process design and procedures are correct and reasonable,and the operation is meticulous to ensure the high precision of the parts,which is beneficial to the machining process of CNC lathes.Quality control.
3.The CNC lathe has a high output power.The machining of CNC lathe can process multiple machining appearances again during the clamping process,generally only need to be processed once,so it can save a lot of intermediate processes in general lathe processing,such as marking,scale detection,etc.,reducing the auxiliary time,and because The quality of the parts processed by CNC lathe is stable,which brings convenience to subsequent processing,and its comprehensive performance is obviously improved.
4.CNC lathe processing facilitates the development and transformation of new products.CNC lathe machining generally does not require a large amount of chaotic processing equipment.By preparing the machining process,parts with chaotic shapes and high precision can be machined.When the product is modified and the plan is changed,only the program needs to be modified and the tool should not be re-planned.Therefore,CNC lathe processing can greatly shorten the product development cycle,providing a shortcut for the development of new products,product improvement and transformation.
