Round insert cutter for difficult-to-cut materials

arp_tit_en-gl.png

arp_main_gl.png

High accuracy run-out provides efficient machining

arp_01_gl.png

Highest level of run-out accuracy increases tool life.

Highly accurate seating realises minimal change of run-out accuracy when indexing the inserts.

arp_02_en-gl.png

Strong clamping system

A wide seating face and 2 side location faces prevent
inserts from moving during cutting.

arp_03_en-gl.png

Optimised chip flow for low cutting resistance

Special rake face on each quadrant of the insert provides the smooth chip flow for low cutting resistance.

arp_04_en-gl.png

Improved chip removal with coolant

The internal coolant is directed slightly above the rake face of the cutting edge so that it is aimed directly at the chip. Forcibly ejecting the chips prevents them from welding to the cutting edge, enabling higher efficiency machining.

Select of coolant nozzle.
It prevents welding to the cutting edge by using a nozzle that can discharge chip at high pressure.

Feature of insert

CVD coated grade for machining of stainless steel MC7020

MC7020 has excellent wear, chipping and thermal crack resistance.
These features prevent the problems usually associated with machining stainless steel over prolonged periods

Improved wear resistance

The micro-grain wear resistant Al2O3 and fibrous TiCN layers deliver excellent wear resistance when milling a wide range of cast irons.

Improved fracture resistance

Use of a specially developed cemented carbide that provides superior resistance to fracture and thermal cracking prevents the cutting edge from sudden fracturing.

Reduced abnormal damage

An extremely smooth black super-smooth coating prevents abnormal damage such as weld chipping.

All black super smooth coating

This smooth outer layer helps to prevent weld chipping.

With accumulated Al-Ti-Cr-N based PVD coating MP7100, MP9100

A fusion of the separate coating technologies; PVD and multi-layering realises extra toughness.
