Part 1 The advantages of turning hardened steel (1) High hardness ,high strength, no plastics (2) Large cutting force, high cutting temperature (3) Easy to produce chips because of the brittleness (4) Bad Thermal Conductivity, and it cant e...

Part 1 The Mechanism of the PCBN inserts used turning the ball screw instead of grinding process Ball screw are divided into Cold rolled ball screw and grinding ball lead-screw two sorts. The technology of turning instead of grinding proces...

CBN Insert, we all know that the main application areas are high hardness cast iron/hard steel and other fields, and Gray cast iron is the most common in this field. Especially for roughing and CNC machining, cbn inserts are more widely use...

Forged steel cold roll, as one important tools for cold-rolled plate and Non-ferrous metal, and it has high hardness, strength, good ductility and impact toughness. So it becomes a big difficult problem on turning forged steel cold roll. Ha...

1. The common casting problems of the cast iron in the casting process Gray cast iron production process include melting casting, modeling core, sand processing, etc., which will result in casting defects, it also include sand quality excep...
