How to reduce tooth deformation

What is the variant of the screw thread in the thread milling process?
The following thread deformation refers to the tooth type tooth type thread milling theory and requirements produced by the different.
Following the deformation of tooth type is a small curve instead of a straight tooth thread angle, and high low.
The following type of tooth deformation is very small, only the use of testing equipment can be observed.
Following this deformation is due to tooth type thread milling helical interpolation when naturally formed.
What factors affect the deformation of the screw thread?
There are many types of deformation in the coarse thread processing, which is caused by the machining of large pitch in the smaller diameter.
Up: how to avoid deformation increase reduce deformation of tooth type deformation in coarse thread processing?
Use the following processing thread cutter correct, milling cutter specially designed can reduce the deformation of screw thread. The following, avoid blind tool selection.
