Gear milling tooth surface roughness, incorrect number of teeth, tooth thickness/tooth pitch/tooth tip taper/tooth tip radial circle runout error reasons

Gear milling tooth surface roughness, wrong number of teeth, tooth thickness/tooth pitch/addendum taper/addendum radial circle runout error explanations are as follows, for reference and understanding.

4 reasons for rough milling tooth surface:

1. Vibration of the machine tool and the tool axis beating.

2. The amount of milling is inappropriate.

3. The side clearance angle of the milling cutter is too small.

4. The choice of cooling lubricating oil is inappropriate.

Three reasons for the incorrect number of milling teeth:

1. The tool wears and the cutting force increases, which makes the workpiece loose.

2. The indexing error of the gear milling machine.

3. The top or other fixtures are loose.

3 major reasons for tooth thickness error of milling teeth:

1. The error of the indexing mechanism of the gear milling machine.

2. Tooth profile error of milling cutter, runout error of milling cutter axis radial and axis several circle.

3. Errors in the center or spindle of the gear milling machine.

2 major reasons for tooth pitch error in milling:

1. The error of the gear milling fixture of the gear milling machine.

2. The error of the indexing mechanism of the gear milling machine.

Three major reasons for the conicity error of the tooth tip of the milling tooth:

1,gearBlank error.

2. Errors in the center or spindle of the gear milling machine.

3. The axis of the milling cutter is not perpendicular to the axis of the workpiece.

Three major reasons for the radial circle run-out error of the milling tooth tip:

1. Gear blank error.

2. The eccentricity error of the indexing plate of the gear milling machine.

3. The radial runout error of the center or spindle of the gear milling machine.
