Troubleshooting
Problem Cause Solution
hole too large • reamer or pilot hole not centered • use a floating reamer chuck or correct pilot hole
• reamer too large • check size of reamer and correct if necessary
• cooling / lubrication problems • change lubricant and increase coolant pressure
dnom
hole too small • worn reamer • replace the reamer
• reaming allowance too small • increase reaming allowance
• cooling / lubrication problems • change lubricant and increase coolant pressure
dnom
conical hole • misalignment between pre hole • re-align or use a floating reamer chuck
(larger bottom) and reamer centers
dnom INTERCHANGEABLE HIGH PRECISION REAMING HEADS
conical hole • misalignment between pre-hole • re-align or use a floating reamer chuck
(larger entrance) and reamer centers • secure the tool axially
• material jammed between reamer and
hole in the upper hole section
dnom
poor surface finish • worn reamer • replace the tool
• misalignment between pre-hole • re-align or use a floating reamer chuck
and reamer centers • increase coolant pressure
• problems with chip evacuation • change cutting parameters
• incorrect cutting parameters • change cutting parameters or coolant conditions
• built-up edge
