Typical applications

  • Brake discs and brake drums
  • Engine components
  • Transmission parts
  • Aluminum housings
  • EV motor housings and battery tray components

Typical components

  • Brake discs and brake drums
  • Engine blocks and cylinder heads
  • Transmission housings
  • E-motor housings and battery tray parts
  • Powder metallurgy gears and shafts

Common materials

  • Aluminum alloys and die-cast aluminum
  • Gray cast iron and ductile iron
  • Hardened steel and bearing steel
  • Powder metallurgy materials
  • Copper and non-ferrous parts

Recommended tool types

  • PCBN inserts for cast iron and hardened steel turning
  • PCD inserts and milling cutters for aluminum finishing
  • PCD drills and reamers for precision holes
  • Carbide CNC inserts for general roughing and turning
  • Custom PCD/PCBN tools for combined operations

Buyer questions before tool selection

  • What material grade and hardness are you machining?
  • Is the cut continuous, interrupted or semi-interrupted?
  • What is the current tool life and main failure mode?
  • What surface finish and dimensional tolerance are required?
  • What is the monthly or annual production demand?

Useful information for quotation

  • Part drawing or current tool model
  • Material grade and hardness range
  • Cutting parameters and machine type
  • Target tool life or cost per part
  • Trial quantity and repeat demand
