PCD cutting inserts for electric motor manufacturing

µm-precise processing with PCD tools

Copper commutators in electric motors require a high-precision surface quality which is achieved by using polycrystalline diamond (PCD). K-inserts for corner radius turning, round inserts with 12-segments( for multiple use) for peel turning or T-inserts for both turning operations: PCD provides precise surfaces and achieves maximum tool lives.

Minimal burr formation
Optimised surface quality
Reduced tool wear

PCD for corner radius turning

  • minimal burr formation
  • low cutting forces
  • reduced tool wear
  • adjustable surface quality

TFGN - Cutting insert

  • suitable for tool holder CTBF and CTCF
  • corner radius turning
  • usable also for peel turning (without radius)

CTBF - Tool holder

  • tool holder with swivelling clamp

KFGN - Cutting insert

  • suitable for tool holder CXVF

CXVF - Tool holder

  • tool holder with swivelling clamp

PCD for peel turning

  • better surface quality (Ra, Rz) at the same parameter setup
  • improved access depending on the commutator design

TFGN - Cutting insert

  • suitable for tool holder CTBF and CTCF
  • peel turning (without radius)
  • usable also for peel turning (without radius)

CTCF - Tool holder

  • tool holder with swivelling clamp

RFGN - Round insert

  • suitable for tool holder CRCF

CRCF - Tool holder

  • optional feature: flexibly adjustable pitch angle

PCD for wear protection - the economical alternative

PCD-tipped wear parts stand out due to minimal friction and low wear in comparison with carbide, cermet or ceramic wear parts.

 PCD-tipped wear parts will be manufactured according to your application. We will lift your operation onto the next level to higher efficiency.

Examples for the use in electric motor manufacturing:
  • prisms
  • bearing shells
  • end-stop
  • pivot bearings

PCD wear parts

Stripping knives with PCD cutting edges​

PCD-tipped stripping knives

The PCD-tipped stripping knives cut the insulating layer of the copper wire with maximum repeat accuracy and low wear:

  • ideal for series production
  • maximum tool lives
  • high machine utilisation
  • maximum efficiency

The guarantee for precise manufacturing

PCD turning tools

Turning tools with polycrystalline diamond (PCD) cutting edges are successfully used for processing aluminium and all non-ferrous metals. CBN, the second hardest cutting material, is considered to be a guarantee for success for turning hardened steels.
