Description

MITSUBISHI WNMG080412-MW UC5115

High-Feed Cast Iron Specialist | 1.2mm Radius Wiper Edge | Made in Japan

Product Overview

The Mitsubishi WNMG080412-MW UC5115 is a high-performance double-sided 80° trigon negative insert precision-engineered for Cast Iron turning. Combining the extreme toughness of the UC5115 CVD coating with a robust 1.2mm corner radius, this insert excels in heavy-duty machining and interrupted cuts. The integrated MW wiper chipbreaker technology allows for significantly higher feed rates without compromising surface finish, making it a premier indexable carbide insert for maximizing productivity on your CNC lathe when working with gray and ductile iron.

Advanced Grade: UC5115 (Ultimate Toughness)

The UC5115 grade is Mitsubishi's premium solution for stable and efficient cast iron turning. It features a specialized CVD coating that offers superior resistance to thermal cracking and adhesive wear. This grade is specifically engineered to handle the abrasive nature of iron while maintaining a high degree of edge toughness, essential for large-scale precision machining in industrial settings.

MW Wiper Chipbreaker Technology

The MW (Wiper) chipbreaker is designed to solve the trade-off between speed and surface quality. By incorporating a wiper edge on the radius, this CNC turning insert allows for a feed rate nearly twice that of a standard insert while achieving the same Ra surface finish. Combined with the 1.2mm radius, it provides the ultimate edge security for heavy roughing and medium-finishing of cast iron.

Recommended Cutting Parameters

Optimized for Cast Iron (K-Class):

  • Cutting Speed (Vc): 130 - 350 m/min (425 - 1150 SFM)
  • Feed Rate (f): 0.25 - 0.65 mm/rev (0.010 - 0.026 ipr)
  • Depth of Cut (ap): 1.0 - 4.5 mm

*Pro Tip: To maximize the Wiper effect, ensure your CNC machine setup is rigid and use a feed rate at the higher end of the recommended range.*

Global Verified Customer Feedback

⭐⭐⭐⭐⭐ "Cycle Time Reduced" - David R., USA
"The MW wiper radius is fantastic. I was able to increase my feed rate on gray iron housings by 60% and the finish still looks like it was ground."

⭐⭐⭐⭐⭐ "Best for Ductile Iron" - Lukas M., Germany
"UC5115 handles the abrasive nature of ductile iron perfectly. The 1.2mm radius provides great edge strength for interrupted cuts."

⭐⭐⭐⭐ "Very Stable" - Kenji H., Japan
"Authentic Mitsubishi quality. Very stable tool life, which is critical for our automated production lines."

⭐⭐⭐⭐⭐ "Great ROI" - Liam G., Australia
"The 6 edges on the WNMG trigon shape make this very cost-effective. Excellent performance for the price."

⭐⭐⭐⭐⭐ "Perfect for Roughing" - Andrzej W., Poland
"We use these for heavy roughing of cast iron components. The inserts are tough and handle the heat very well."

Technical Q&A

Q: What makes the 'Wiper' (MW) special?

A: The wiper edge is a flattened radius. In CNC turning, it allows you to increase feed rates while maintaining a high-quality surface finish, significantly reducing cycle times.

Q: Is UC5115 suitable for interrupted cuts?

A: Yes, UC5115 is designed for high impact resistance, making it one of the best choices for interrupted cutting in cast iron.

Q: How many edges do I get per insert?

A: As a WNMG trigon insert, it features 6 usable cutting edges, offering 50% more value than a standard 4-edged diamond insert.

Expert Machining Tip: UC5115 vs. MC5015

For Stable, Continuous High-Speed turning of iron, MC5015 is the king. For Heavy Interrupted Cuts or older machines where toughness is required, UC5115 is the better choice.
