Product Information:

Helical milling is a hole-making machining process in which the cutter proceeds a helical path while rotating around its own axis, used to produce helical parts like helical gears, spiral flute milling cutters, twist drills, and helical cam grooves.

SPMT for helical milling.

S - Square shape of turning insert.

P - Insert with clearance under main cutting edge (11°).

M - Tolerances and dimensions of carbide turning insert.

T - Hole through insert and single sided chip breaker.

Specifications:

• : Recommended Grade

O: Optional Grade

Application：

The type of carbide grade and the coating on inserts are originally intended for steel, stainless steel and cast iron. But it also performs when milling other alloys.

The company has a complete blade manufacturing process equipment production line from powder raw material preparation, mold making, pressing, pressure sintering, grinding, coating and coating post-treatment. It focuses on the research and innovation of the base material, groove structure, precision forming and surface coating of carbide NC inserts, and constantly improves the machining efficiency, service life and other cutting properties of carbide NC inserts. After more than ten years of scientific research and innovation, the company has mastered a number of independent core technologies, has independent R&D and design capabilities, and can provide customized production for each customer.
