No. of threads NOMINAL ACTUAL Thread is cut wrongly axially cutting lead pressure on tapping chuck too great select the right cutting lead pressure Pitch distortion (plug gauge cannot be screwed in over full thread length on the workpiece) tap is not cutting true to pitch select right tool select right cutting lead pressure with length adjustment chucks reduce feed to 9% Thread oversize at the entry wrong cutting lead pressure use compensation chuck(tension) use lead srcrew select right tool Thread surface not clean wrong tool type select right tool chip jam see thread too large chip jam core diameter too small select right core diameter material built-up on thread flanks use tools with surface treatment improve coolant system cutting speed to low increase cutting speed Tool life too short wrong tool type select right tool type cutting speed too high or too low adjust cutting speed composition and supply of coolant inadequate provide suitable, sufficient coolant premature wear due to lack of or unsuitable surface treatment use coated tools, if necessary solid carbide tools 6 7 8 9 Important: See chapter 9 for more application details and safety notes!
