Solution for Reaming Problems

FAULT CAUSE REMEDY
Bore too large Reamer too big Controlling the reamer diameter
Alignment reamer to machine not precise Correct alignment or use compensation holder
Built up edge Correct cutting speed and feed, use another coolant
Unsuitable coolant Use another coolant
Reamer is not running true Use compensation holder
Depth of cut too small Correct depth of cut
Papered bore Faulty alignment Correct alignment or use compensation holder
Built up edge Correct cutting speed and feed, use another coolant
Bore not true, shows chatter marks Concentricity an alignment error too large Correct concentricity and alignment, or compensation holder
Wrong cutting geometry Use face cutting reamer
Deformation through fixation of the work piece Correct fixation of the work piece
FAULT CAUSE REMEDY
Surface quality unstatisfactory Cutting edges blunt Regrind correctly
Reamer does not run true Correct concentricity or use compensation holder
Wrong machining data Check back on data as instructed
Bad chip flow (insulfficient coolant) Use tool with internal coolant supply, supply proper coolant with strong jet
Feed marks in bore Cutting edges fragment Regrind or replace reamer
Built up edge Correct cutting data
Reamer jams Reamer taper too slight because of wear relieving Regrinding with adequate reamer taper
Circular land too wide Make a relief grind as instructed
Bore too small Worn reamer Expand, regrind or replace reamer
Wrong coolant Use another coolant
Depth of cut too small Increase cutting depth
Deformation through fixation of the work piece Correct fixation of the work piece
