What effect will the inner hole of the reamer cause if it is not round?

In the process of manufacturing reamer, many accidents will inevitably occur, such as operator error, design error, quality inspection error, etc. The inner hole of diamond reamer will have a certain impact on production. Let's explain it below. Several effects.

① The first effect is that the reamer is too long, the rigidity is insufficient, and vibration occurs during reaming.

②The main declination angle of the reamer is too small, the reamer margin is narrow, and the reaming allowance is too large.

③There are gaps and cross holes on the surface of the inner hole, and there are blisters and pores on the surface of the hole.

④ The spindle bearing is loose, there is no guide sleeve, or the clearance between the reamer and the guide sleeve is too large.

⑤Because the thin-walled workpiece is clamped too tightly, the workpiece is deformed after unloading.

⑥ The influence is that the reaming allowance is too large, the rear angle of the cutting part of the reamer is too large, and the diamond reamer edge is too wide.

⑦If the inner hole is not round, it will also affect the air holes and sand holes on the surface of the workpiece, and the spindle swing is too large.
