Analysis of machining accuracy of rack manufacturers
In the process of rack processing, the surface roughness is different for a number of reasons, which leads to errors. Below we follow the rack manufacturers to see the specific causes of the racking error:

1. The precision of the machine tool transmission chain is not high. During the operation of the machine tool, multiple vibrations or impacts occur, which affects the stability of the machine tool transmission.

2. The contact between the spindle of the table and the conical guide surface of the table is not satisfactory. The contact of the tapered guide surface is too hard, and the table rotates heavily. Vibration occurs during operation. Causes errors in processing.

3. The knife mechanism is not working properly, and the knife is scraped onto the surface of the workpiece.

4. The quality of the toothed cutter is poor.

5. The feed rate is too large, causing the cutting of the rack to be not timely, which results in rough surface of the rack.

6. The rack blank is not installed properly, and vibration occurs during cutting.

7. The cutting fluid dirty rack, the rack machining error analysis or rushed into the cutting slot.
