GTPAMultifuntioning tool for machining non-ferrous material| Swiss CNC Lathes

Best tool for machining aluminum valve spool parts

High-precision and high efficiency machining

Grooving - side turning capability
Single pass machining to improve productivity

2 grades to choose from for machining needs
PD1 - PCD grade
  • Increased strength with fine grain polycrystalline diamond material.
  • Adhesion resistance for non-ferrous materials
  • Prevents built-up edge for high precision and stable machining
  • Hard fine grain diamond to achieve high speed machining and long tool life
KM1 - carbide grade
  • Uncoated fine grain carbide grade designed for machining non-ferrous material
  • Up sharp edges and mirror finished inserts to achieve high-quality machined surfaces
  • Significantly lower insert cost compared to PCD inserts

Case study

Material :
Cutting speed :
90~170 m/min
Feed :
0.04 mm/rev
0.5 ~ 5.0 mm
Coolant :

300 pcs

Competitor’s PVD coated carbide

200 pcs

Competitor's product required 3 grooving passes and inserts were often chipped and damaged. Cycle time was over 3 minutes.
NTK's KM1 insert machined part in one pass reducing the cycle time to 1 minute 50 seconds.

Material :
Cutting speed :
200 m/min
Feed :
0.06 mm/rev
Coolant :

10,000 pcs

Competitor's brazed carbide insert
1,000 pcs

Cut time shortened with one pass traversing.
PD1 insert generated super surface finish with efficiency. Tool life is extended with inserts adhesion resistance
