Automotive – Motor Drive

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.

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.

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.

More product info

• 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.

More product info

• 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.
