At present, CNC lathe turning is an important part of CNC machining. Compared with ordinary lathes, it has many advantages, such as high machining accuracy, straight line processing, and automatic speed change. It can be seen that the processing of CNC lathes can fully meet the requirements of ordinary lathe processing, and the accuracy is more accurate, such as rotating body parts. Next, PTJ CNC machining will discuss the types of CNC lathe turning parts.
Rotary body parts are divided into bushings, roulettes and other types. The difference between shaft sleeve and roulette parts is the aspect ratio. Generally, parts with an aspect ratio greater than 1 are regarded as shaft parts; parts with an aspect ratio less than 1 are regarded as roulette parts.
1. Shaft sleeve parts
The length of the sleeve parts is larger than the diameter, and the machining surface is mostly the inner and outer circumferential surfaces. The generatrix of the contour of the circumferential surface can be a straight line parallel to the z axis, and the stepped shaft can be formed by cutting, and there can be threads and retraction grids on the shaft; it can also be a slant line, which can form a tapered surface or tapered thread; or it can be a circular arc or Curve (programmed with parametric equations), cutting to form a curved surface.
2. Roulette parts
The diameter of the roulette parts is greater than the length, and the swiss turning surface is mostly the end face. The generatrix of the end face caster can be a straight line, a slant line, an arc, a curve or a face thread, a tapered thread, etc.
3. Other parts
CNC lathe is the same as ordinary lathe. It can process eccentric shaft or machine hole or cylinder on box or plate by installing special chuck or fixture.
