*¹ ML-type:
The feeds relate to workpiece material groups 1-9 (plain carbon and low alloy steels) and 15-16 (grey cast iron).
For machining groups 10-11 (high alloy and tool steels) the table values should be multiplied by 0.7, for machining
groups 12-13 (martensitic stainless steel) and 17-18 (nodular cast iron) - by 0.85 and for machining group 38.1
(hardened steel, HRC 45 max) - by 0.55.
*² AX-type:
The feeds relate to workpiece material groups 1-9 (plain carbon and low alloy steels).
For machining groups 10-11 (high alloy and tool steels) the table values should be multiplied by 0.7,
for machining groups 12-13 (ferritic and martensitic stainless steels) - by 0.85.
*³ HP-type:
The feeds relate to workpiece material groups 1-4 (plain carbon steel).
For machining groups 12-13 (ferritic and martensitic stainless steels) the table values should be multiplied by 0.85.
