General Engineering (Czech republic)
Component:
Hydraulic circuit parts
E698M6
Material: Coolant:
42CrMo4 / EN 10083 (Alloy steel, 250 HB) Yes, external, water soluble oil emulsion (~8%) Blind hole threading of M6 at 2.5xD, pre-drilled Ø 5.1 mm hole is 21 mm deep and made by solid carbide drill. Run in Tajmac MCFV 1060 CNC using a Tapmatic SynchroFlex SFT II75 tap holder. Serious problems caused by nesting, an average of 1000 threads was reached current taps. The best alternative competitor tap improved tool life to 1353 threads in average, but nesting problems still remained frequent.
