Troubleshooting Guide

Oversized Hole • Reamer is running eccentric to the center of the machine spindle. system with radial adjustment. • Excessive misalignment causing reamer to cut on back taper.

Use modular

Fix the misalignment.

• Material buildup on cutting edges. • Reamer diameter is too large.

Replace the coolant or change the cutting speed.

Use smaller reamer or regrind existing reamer.

Undersized Hole • The reamer diameter is too small. • The reamer diameter is worn. • The coolant is not suitable. • Stock allowance is too small. • The cutting speed is too low.

Use larger reamer.
