TurningMillingDrillingTechnicalInformationIndex Trouble shooting – turning Technical information Trouble shooting – threadingProblème Cause Solution A Big flank wear – Cutting speed too high – Reduce cutting speed – Width of cut too small – Reduce number of width of cut – Insert over/under centre line – Adjust insert height Asymmetric wear on left – Width of cut not optimal – Adjust width of cut and right cutting edge – Inclination angle and lead angle are not optimally – Change the shim to get the correct angle aligned Breakage – Cutting speed too low – Increase cutting speed B – Cutting force too high – Increase number of width of cut – Reduce width of cut – Unstable conditions – Improve clamping and overhang to avoid vibrations – Bad chip control – Increase coolant pressure for better chip removal Déformation plastique – Cutting speed and temperature too high – Reduce cutting speed – Increase number of width of cut – Reduce width of cut – Insufficient coolant supply – Improve coolant supply C Mauvais état de surface – Cutting speed too low – Increase cutting speed du filet – Insert over/under centre line – Adjust insert height – Bad chip control – Change feed rate and/or width of cut Profil de filet incorrect – Wrong insert height – Change insert height – Tool holder doesn't form a 90° angle – Adjust tool holder – Pitch error in machine – Adjust machine D Profil de filetage de – Wrong insert height – Change insert height profondeur insuffisante – Breakage of cutting edge – Change insert – Excessive wear – Change insert Formation d'arêtes – Temperature on cutting edge is too low – Increase cutting speed rapportées – Often occurs when machining of carbon steel and – Use grade with sufficient toughness (PVD coated) stainless steel Vibrations – Wrong cutting data – Increase or highly decrease cutting speed E – Wrong insert height – Change insert height – Insufficient clamping – Improve clamping system and minimise overhang A 449
