Friday, February 23, 2018

The Tool
The T271 family is designed for 2 x Dn thread lengths, with an additional neck in order to bridge interference contours. The universal indexible insert threading milling cutter from Walter Tools is manufactured for high cutting rates along with high feeds per tooth. With adjustable coolant supply, the T271 has radial and axial coolant outlets.

The Application
The T271 tool can be used universally with ISO P,M,K,S and H up to 55 HRC. It is designed for threads with a nominal diameter from 24mm, with a pitch range of 1.5mm/18-4 TPI, threading a depth of up to 2.5 x Dn.

The Insert
The wear resistant universal grade WSM375 has easy cutting geometry with a positive basic shape with three cutting edges. Defined with a corner radii the inserts produces threads in accordance with various standards.

The Strategy
It is recommended that the thread be produced with a radial cut using synchronous milling. The programming radius can be determined using Walter GPS. Non cutting passes can be carried out without radius corrections.
