12 tips to help diagnose problems

Problem                         Cause                                           Remedy
     Heavy chisel edge wear
                                 cutting speed too low                          increase cutting speed
                                 feed too high                                  reduce feed
                                 excessive honing of cutting lip                reduce cutting lip honing

Crumbling at intersection,       clearance angle too small                      increase clearance angle
web thinning and cutting lip     excessive honing of cutting lip                reduce cutting lip honing
                                                                                 apply suitable tool
                                 incorrect tool type
                                                                                 reduce cutting speed
Plastic deformation of outer     cutting speed too high                         increase volume/pressure
corner                           insufficient coolant volume                    correct honing

                                 incorrect or no honing at corner

Misalignment                     non rigid conditions, insufficient workpiece   rigid clamping of workpiece
                                                                                 check and correct concentricity if possible
                                   clamping

                                 deviation from concentricity too large

                                 spotting area transverse                       use milling cutter (2-fluted) for spotting

                                 chisel edge too large                          reduce chisel edge

Heavy burring on break-          feed too high                                  reduce feed
through                          max. wear values exceeded                      reduce tool change intervals
                                 excessive honing of cutting lip                reduce cutting lip honing

Unsatisfactory surface quality   non rigid conditions, insufficient workpiece   rigid clamping of workpiece
                                                                                 check and correct concentricity if possible
Ra                                 clamping

                                 deviation from concentricity too large

                                 insufficient coolant volume                    increase volume/pressure
