GTAH, GTBH, GTCH

Screw Designed for Front and Back Clamping
MS7025 grade for stainless steel and MT2015 grade for non-ferrous metals added to the series.

Back Clamping Mechanism

Even gang type tool posts on Swiss automatic lathes, tools can be changed quickly and accurately using the same wrench on both sides, improving machine operating efficiency.

PVD Coated Grades for High Precision and Small Parts Machining
MS7025

Dramatically improved welding and wear resistance in low feed machining with a more precise nano-multilayer coating

Features

Nano-Multilayer Coating

By combining the high lubrication layer with excellent welding resistance, and the high hardness layer with a greater wear resistance that suppresses the progress of wear at the nano-level, the film damage is significantly reduced and the welding and wear resistance are dramatically improved.

Effects of the High Lubrication Layer

The nano-level, high lubrication layer suppresses built-up edge caused by chip welding which tends to occur in low feed machining and in addition reduces machining marks on the component surface.

Cutting Performance

Comparison of Surface Roughness and Cutting Edge Damage : Pure iron-based soft magnetic materials

The surface roughness is excellent because damage caused by welding is suppressed. It also has excellent wear resistance.

Surface Roughness with Finishing Groove Bottom Diameter 11mm

Cutting Edge Damage

Carbide Grade (Non Coated)
MT2015

It has the usual wear resistance of carbide but is also tough and therefore resists sudden fractures. It can be expected to extend the life of non-ferrous metals such as aluminium alloys.

Cutting Performance

Comparison of Cutting Edge Damage : A6061

By suppressing damage to the cutting edge caused by welding, longer tool life can be expected.

PVD Coated Grades
VP15TF/VP15KZ

(Al,Ti)N coated grade with excellent heat resistance and adhesion strength.
It is highly versatile and can be used in a variety of machining processes.
