Common problems
|
Solutions
|
Reamer breakage,
thermal damage
|
1.The guide hole is defective before reaming, for example, linearity is not good.
2.Adjust machining allowance to avoid tool breakage caused by too large allowance.
3.If the chip removal is obstructed, select a reamer with larger chip pocket.
4.Ensure sufficient coolant supply.
5.Adjust rotating speed and feed speed appropriately.
6.Increase the rigidity of machine, holder and reamer
7.Improve the sharpness of reamer to make cutting easy and fast.
8.Excessive abrasion occurs on cutting edge, which means tool life has expired. It is recommended to change or regrind tool
|
Damage on reamer shank
|
1.Check whether the shank hardness is enough. Too low hardness would cause
deformation, and too high hardness may cause breakage
2.Check the conjunction of holder and bushing. Do not use a defective holder.
|
Short durability
|
1.Enhance the hardness of reamer cutting edge.
2.Select the reamer made by advanced material.
3.Check the coolant.
4.Use surface treatment for reamer such as nitride process.
5.Change the straight flute to helical flute.
6.Check all factors affecting machining precision.
|
Scratches on hole surface
|
1.Make sure no built-up is on the reamer surface.
Improve workpiece holding.
|
Trumpet-shaped entry hole
|
1.Improve workpiece holding.
2.Check radial run-out after clamping reamer.
3.The center of reamer is not in alignment with the hole center. Adjust the concentricity of hole and reamer.
|
Hole oversizing
|
1.The center of reamer is not in alignment with hole center. Adjust the concentricity of
hole and reamer.
2.Improve workpiece holding.
