For mechanical equipment parts, many require precision, but due to various reasons, the surface roughness varies. Let's take a look at the causes of errors in rack machining?

The precision of the machine tool transmission chain is not high, leading to vibrations or shocks during operation, which affects the stability of the machine tool transmission.

2. The main shaft of the workbench does not meet the requirements when in contact with the conical guide surface of the workbench housing; the contact with the conical guide surface is too firm, causing the workbench to rotate heavily. Vibration occurs during operation, leading to errors in the machining process.

3. Causing the cutting mechanism to malfunction,刮刀刮擦工件表面.

4. Poor quality of gear cutter blade grinding.

5. Excessive feed rate resulted in the cutting of the gear teeth not being timely, thereby causing the gear rack surface to be rough.

6. The rack blank could not be installed against the support, causing vibration during cutting.

7. The cutting fluid is contaminated or has entered the cutting gear slots, resulting in substandard surface quality of the rack.
