Automotive – Motor Drive

Motor Drive

In recent years, the shift toward electrification in the automotive industry has been accelerating, and motor drives are playing an increasingly important role as power sources for electric vehicles.
Motor drives are essential components for achieving efficient and reliable power transmission, and improving their performance is a key requirement.
To meet these precise machining needs, Tungaloy offers innovative cutting tool solutions. By balancing high machining accuracy and productivity, we help optimize our customers’ manufacturing processes and support the development of competitive products.

Tooling concepts

  • Reducing machining time and the number of tools used through process integration.
  • Significantly improving downtime during tool changes by using the TungCap system.
  • Achieve high-efficiency machining through high-feed finish milling with AddMultiTurn technology.
  • Improve machining efficiency and lower production costs by applying hard turning in post-hardening processes, eliminating the need for grinding.

Featured process

Process 1: Combination face milling with chamfering

Benefits

  • Reducing machining time and the number of tools used through process integration.
  • Operations on weakly clamped forged pieces.
  • Cutter with a 70° cutting angle:
    • Ideal angle for a balance between main and back forces.
    • Provides stability and reliable control, especially with unstable clamping forces on forged materials.
  • The TungCap tooling significantly reduces machine downtime.

  • The AH3225 grade achieves an extraordinary long life by balancing wear resistance and fracture resistance at a high level.
  • Sharp cutting edge and large rake angle reduces cutting resistance.
  • Economical with 10 cutting edges.

  • Chamfering cutter adopting economically efficient single-sided 4-corner inserts.
  • Achieving high machining surface quality by suppressing burr and chatter with sharp cutting edges.
  • Using the AH725 grade known for its high wear resistance.

Process 2: Rough external turning

Benefits

  • The high-feed edge geometry with back turning enables highly efficient machining, surpassing conventional ISO tools by approximately 200% in turning operations.
  • The back turning effectively minimizes the occurrence of ringing shape burr, a common issue in stepped shaft machining.
  • The Y-PRISM insert clamping system, known for its uniqueness and robustness, ensures excellent clamping rigidity. This feature allows for stable multi-directional machining and facilitates high-efficiency processing.

6C-TOMG-TM
  • Economical with a double-sided 6-corner specification.
  • An 80° corner angle type applicable from medium to rough cutting operations.
  • The T9215 grade ensures exceptional wear and fracture resistance in steel turning operations, providing outstanding performance.

Process 3: Finish external turning (Hard turning)

Benefits

  • Even for processes that require two steps to avoid interference, process integration is possible by using a holder for grooving.
  • Equipped with a large arc wiper on the front cutting edge, it maintains excellent surface finish quality even during high-feed external diameter machining.
  • The TungCap tooling significantly reduces machine downtime.
  • With the application of the TungTurn-Jet holder, coolant can be supplied from two directions: the cutting edge’s rake face and clearance face. This enhances the cooling effect on the cutting edge and achieves longer tool life.

CBN insert
  • Multi-functional system for diverse grooving needs.

  • By adopting the “WavyJoint” shape, which allows for a larger brazing surface area, the softening of the brazing material due to cutting heat is prevented even during high-feed machining.

  • The coated CBN grade “BXA10” for hardened steel turning is the first choice for continuous to light interrupted machining.
  • Crater wear resistant CBN substrate for process security.
  • Unique multilayered PVD coating technology enhances the grade’s wear resistance and edge toughness for maximum tool life.
