What are the main reasons for producing waste products when milling straight cylindrical gears?

Publisher: Administrator    Date:2023-04-26

The main reasons for producing waste products during milling straight cylindrical gears are:

(1) The reason for the discrepancy between the number of teeth and the requirements of the pattern is that the pattern was not carefully read; Indexing calculation error or indexing head adjustment error.

(2) The reasons for unequal tooth thickness or excessive tooth pitch error are: incorrect operation of the indexing head, failure to eliminate the clearance between the indexing head worm pair when the indexing handle is retracted for correction after multiple rotations; The workpiece is not aligned properly, resulting in excessive radial circular runout of the workpiece.

(3) The reasons for incorrect tooth height and thickness are: incorrect adjustment of milling depth, incorrect selection of milling cutter module or incorrect selection of cutter number.

(4) The cause of gear tooth deviation is that the milling cutter is not aligned with the center.

(5) The main reasons for the roughness of the tooth surface are: the milling cutter is blunt or the milling amount is too large; Excessive swing difference after clamping the milling cutter; The workpiece is not properly clamped, and the machine tool and indexing head are not adjusted and tightened properly, resulting in vibration during cutting.
