Skh51 Machining Feed And Speed Choices That Keep Tools Alive - China

SKH51 Machining – Practical Feed And Speed Notes For Toolrooms Machining SKH51 in the annealed condition is very manageable if you respect a few rules.

The steel cuts much like other tungsten-molybdenum high speed steels, but its relatively high vanadium content forms hard carbides that wear out tool edges faster than plain carbon steels do.

The fix is not exotic equipment – it is correct insert geometry, conservative feeds, and generous cooling.

Field-tested guidelines from our stockists and toolroom customers:

- Turning in annealed condition: carbide inserts, low cutting speeds, positive rake, and steady feed rather than rubbing

- Milling: light radial engagement, climb milling preferred, flood coolant to carry away heat

- Drilling: fresh HSS-Co or solid carbide drills, peck cycles on diameters above 12 mm, never let the drill dwell

- Grinding after hardening: keep wheels dressed and cool; SKH51 grinds well but dislikes excessive infeed

- Avoid interrupted-cut overheating; a burnt edge on the workpiece means lost hardness in the finished tool Because we supply SKH51 fully annealed and spheroidized, customers can rough machine profiles before heat treatment, then finish by grinding — the workflow most tread makers already run.
