During the rack manufacturing process, various factors contribute to varying surface roughness, which consequently leads to errors. Let's follow the rack manufacturer to explore the specific reasons that cause errors in rack manufacturing:

The precision of the machine tool transmission chain is not high, resulting in multiple vibrations or shocks during the operation of the machine tool, affecting the stability of the machine tool transmission.

2. The main shaft of the workbench does not meet the requirements in contact with the conical guide surface of the workbench housing; the contact is too hard on the conical guide surface, resulting in a heavy rotation of the workbench. Vibration occurs during operation, causing errors in the machining process. 3. The knife return mechanism is not functioning properly, scraping against the workpiece surface. 4. Poor quality of the blade dressing of the gear cutting tool. 5. Excessive feed rate causes the gear cutting tool to be不及时 in cutting the gear rack, resulting in a rough surface of the gear rack. 6. The gear blank is not properly mounted, producing vibration during cutting. 7. Contaminated cutting fluid affects the gear rack, possibly causing machining errors or being flushed into the cutting gear slots.
