The importance of Dalian high speed CNC vertical lathe coordinate system

High speed CNC vertical lathe is a kind of vertical lathe which is more common and used. In addition, it is also a website product and related to website keywords.

CNC single column vertical lathe can be divided into small and large ones, that is, there are two specific types: small CNC vertical lathe and large CNC vertical lathe. From the specific aspect of programming, there is no big difference between it and the NC sleeper, but there are differences in nuances, because the Z axis of the NC vertical lathe is vertical and the X axis is horizontal to the right.

In the NC single column lathe, the rotational speed of the workpiece has a decisive factor. Moreover, from a professional point of view, it is for workpiece material, tool material and cutting fluid. Through them, the specific value of workpiece speed is determined. If the workpiece is made of carbon steel and the cutting tool is made of coated cemented carbide, and the coolant is fully poured, the rotating speed of the workpiece can reach 160r / min.

CNC vertical lathe can also be divided into single column and double column. However, there is no comparability between these two specific types, because they are different in application scope, performance and price. Therefore, this conclusion can be drawn. If the rigidity requirement is not high, single column CNC vertical lathe can be used; otherwise, double column CNC vertical lathe can be used.

2、 How to choose the accuracy of vertical lathe

CNC vertical lathe can be divided into ordinary type and precision type according to accuracy. Generally, there are 20-30 accuracy inspection items of CNC machine tools, but its characteristic items are: single axis positioning accuracy, single axis repeated positioning accuracy and roundness of test pieces processed by more than two axes. The positioning accuracy and repeated positioning accuracy comprehensively reflect the comprehensive accuracy of the moving parts of the shaft.

Various types of lathes are commonly used to process various kinds of workpieces, such as drilling, tapping and expanding the end face of the dial, which can also be used in response to the general situation of the dial and expanding the dial, and various types of lathes can also be used for drilling and expanding the end face of the dial.

Especially the repeated positioning accuracy, the CNC vertical lathe reflects the positioning stability of any positioning point of the shaft in the stroke, which is the basic index to measure whether the shaft can work stably and reliably. At present, the software in CNC system has rich error compensation function, which can stably compensate the system error of each link on the feed transmission chain.

The gap, elastic deformation and contact stiffness of each link of the transmission chain often reflect different instantaneous movement with the load of the workbench, the length of the moving distance and the speed of the moving positioning speed. In some open-loop and semi closed-loop feed servo systems, the mechanical driving element after the measuring element is affected by various accidental factors and considerable random errors, such as the actual positioning position drift of the worktable caused by the thermal elongation of the ball screw. In short, if you can choose, choose the equipment with better repeat positioning accuracy.
