TPGN 160302 DX140 turning indexable insert — polycrystalline diamond for high-speed aluminium turning — Tungaloy

The TPGN 160302 DX140 is a triangular ISO turning insert designed for high-speed machining of aluminium, non‑ferrous metals and abrasive non‑metallic materials, offering long tool life and consistent surface quality.

• High-speed PCD grade DX140
• ISO-compatible triangular form
• Very long tool life for aluminium machining
• 0.2 mm corner radius for precision finishing

Increased productivity through PCD-grade performance

The combination of polycrystalline diamond (PCD) cutting material and the DX140 grade delivers markedly higher cutting speeds and extended service intervals compared with conventional carbide inserts. This turning insert, listed as TPGN160302‑DIA, is specifically engineered for productive machining of aluminium and other non‑ferrous materials: the wear resistance of the PCD layer reduces downtime for insert changes, which directly supports a smoother production flow and lower unit costs. The result is measurable process efficiency without sacrificing component quality.

Secure seating and ISO-standard compatibility for reliable runs

Designed to match ISO geometry and tolerance classes, the insert’s triangular form with a 60° included angle ensures compatibility with standard external holders and boring bars. Compatibility depends on form, relief angle, fastening and plate thickness; the insert is supplied without a hole, so selection of a matching clamping system or shim set is essential. When mounted correctly, the arrangement provides stable cutting conditions and repeatable positioning, reducing vibration and improving dimensional consistency in series production.

Geometry optimised for precise finishes and small features

With a 0.2 mm corner radius and an 11° relief angle, the insert supports fine finishing passes and accurate profile generation. The 3.18 mm plate thickness contributes to rigidity at the cutting edge while the carbide substrate provides a stable backing for the diamond cutting layer, combining toughness with the wear resistance of PCD. These geometric choices help achieve a consistent surface finish and protect edge integrity when machining thin walls or small contours.

Application guidance and selection advice for best results

For external and internal turning operations, choose the DIA chipbreaker and the DX140 grade when machining aluminium or abrasive non‑metallics; the chipbreaker and grade must align with material, cutting strategy and machine stability. The system typically comprises the ISO insert, a suitable external holder or boring bar, a shim/locking set and replacement screws. Where high removal rates or long unattended runs are required, this PCD option provides the best balance of speed and life, particularly for components produced in batches or continuous series.

FAQ

What materials is this insert best suited for?
The TPGN160302‑DIA DX140 insert is optimised for aluminium, other non‑ferrous metals and abrasive non‑metallic materials thanks to its PCD cutting layer and DX140 grade.

Can the insert be used for both external and internal turning?
Yes, the geometry and chipbreaker selection support both external and internal turning; pairing the insert with an appropriate boring bar or external holder ensures stable performance.

How does the DX140 grade improve productivity?
DX140’s PCD cutting surface offers high wear resistance and allows high cutting speeds, which reduces the frequency of insert changes and increases net cutting time on the machine.

What mounting considerations are important for this ISO insert?
Compatibility depends on form, relief angle, fastening method and thickness; since this plate is supplied without a hole, ensure the chosen clamping system or shim set matches the triangular plate and its 60° angle.

Is the insert suitable for finishing passes?
Yes, the 0.2 mm corner radius and 11° relief angle provide the geometry required for controlled finishing cuts and good surface integrity.
