Description

MITSUBISHI WCMT06T304 US735

High-Performance CVD Coated Carbide | The Stainless Steel Authority

Product Overview

The Mitsubishi WCMT06T304 US735 is a robust 80° trigon indexable insert specifically engineered for high-demand stainless steel turning. Featuring the specialized US735 CVD coating, this insert excels in heat dissipation and edge toughness. It is designed to handle the high temperatures and work-hardening characteristics of austenitic and martensitic alloys, ensuring stable performance in both continuous and interrupted cutting conditions.

Recommended Cutting Parameters

Optimized for CNC Lathe operations in stainless and alloy steels:

  • Cutting Speed (Vc): 100 - 180 m/min (330 - 590 SFM)
  • Feed Rate (f): 0.10 - 0.25 mm/rev (0.004 - 0.010 ipr)
  • Depth of Cut (ap): 0.5 - 2.5 mm

*Note: Use high-pressure coolant for best results in gummy stainless steel.

Grade & Coating: US735 CVD Specialist

The US735 grade is a dedicated CVD (Chemical Vapor Deposition) coated carbide designed to combat the intense heat generated during medium turning of stainless steel. The multi-layer coating acts as a thermal barrier, protecting the sub-micron substrate from edge deformation and crater wear.

Optimized Chipbreaker Geometry

With its positive rake angle, the WCMT geometry significantly reduces cutting resistance and vibration. The 0.4mm corner radius provides a balance between edge strength and surface finish, preventing work hardening of the material surface during precision CNC machining.

Questions & Answers

Q: Can WCMT06T304 be used for aluminum?
A: While it can cut, it is not optimized for aluminum. For non-ferrous metals, an uncoated HTI10 or polished VP series insert is better to prevent material welding.
Q: What makes US735 different from VP15TF?
A: US735 is a CVD coated grade designed for higher heat resistance and toughness in difficult stainless steel, whereas VP15TF is a PVD coated grade for general-purpose versatility.
Q: Does this fit my boring bar?
A: Yes, it fits any SWLCR or SWGCR holder that takes 06 size trigon inserts.

Expert Tip: Carbide Grade Selection

For the best CNC productivity, pair the WCMT06T304 with rigid machine setups. If you are experiencing vibration, reduce the feed rate slightly before lowering the cutting speed to maintain the CVD coating's thermal efficiency.
