How to process precision parts in thread

There are generally two types of feed for thread cutting when machining precision parts. One is the straight feed method and the other is the oblique feed method. When the thread profile depth and pitch are large, the tool can be fed multiple times. Cutting depth allocation methods are constant and decreasing.

1. When processing threads, only the X direction feed is used for each turning. The method of the left and right cutting edges of the thread turning tool participating in the cutting at the same time is called the straight feed method. Straight-line method programming is relatively simple, and it can obtain a more accurate tooth shape, which is often used for thread processing of thread pitch P<2mm and brittle materials.

2. When turning a thread with a large pitch, due to the deep thread groove, in order to smooth the rough turning, the method of simultaneous feed of two axes is called the oblique feed method. Straight threading is the simultaneous cutting of two cutting edges; oblique threading is single-edge cutting, which is not easy to pierce in turning, and a small surface roughness value can be obtained.

Precautions for thread turning

1. Generally, when cutting threads, the rough pitch to fine pitch are carried out at the same pitch. When the position encoder installed on the spindle detects the first rotation signal, it starts cutting. Therefore, even if cutting many times, the starting point of the cutting on the workpiece circumference of the precision part processing remains unchanged. However, from rough turning to finishing turning, the rotation speed of the main shaft must be constant. When the rotation speed of the main shaft changes, the thread cutting will produce disordered teeth.

2. Generally, due to the lag of the servo system, irregularities will appear in the thread lead at the beginning and end of thread cutting. In order to consider the thread accuracy of this part, when cutting the thread on the CNC lathe, it is necessary to set up the speed-increasing feed section and speed-reducing feed section. Therefore, in addition to the effective length L of the thread, the actual length of the processed thread should also include the length of the speed-up section and the speed-down section. Its value is related to the pitch and speed of the workpiece processed by the precision parts, which is set by each system and is generally greater than one guide. Cheng.
