CBN cutting insert

Product catalog summary

Introduction
Tungaloy's report discusses advanced cutting materials, specifically PCBN (BX Series) and Ceramic (LX11), for hard turning applications. It emphasizes the transition from traditional grinding to hard turning, highlighting the efficiency and cost benefits.

Specifications and Features
The report outlines the benefits of PCBN and ceramic materials in machining, such as precise machining with minimal tolerances and high surface quality, eliminating the need for further grinding. Dry machining also reduces production costs.

PCBN and Ceramic Cutting Materials
Tungaloy has been a leader in developing PCBN and ceramic cutting materials since the 1960s and 1970s, offering economic solutions for both continuous and heavily interrupted cutting.

Tungaloy Advantages

Multi-corner Type: Provides a cost-effective alternative to single-corner inserts, reducing stock requirements.
Coated PCBN: Grades BXC50 and BXC30 offer high wear resistance and toughness for various cutting conditions.
Big PCBN Inlay: Enables multiple regrinding operations, optimizing cutting forces and temperatures.
Indexing of Cutting Edges: Simplifies use and reduces production costs.

Grade Variety
The document details specific PCBN grades (BX310, BX330, BX360, BX380, BXC30, BXC50) and their applications, suitable for high-speed continuous and interrupted turning of hardened steels and other hard materials.

Ceramic Grade LX11
The LX11 ceramic grade is ideal for hard turning at various cutting depths and feed rates, offering an economical option for machining hard-soft cutting zones in one operation.

Cutting Conditions and Applications
The report provides detailed cutting conditions for various PCBN and ceramic grades, including hardness, feed rate, cutting depth, and speed, tailored for continuous, light, medium, and heavy interrupted cutting.

Conclusion
Tungaloy's innovative cutting materials, including PCBN and ceramic grades, offer significant advantages in hard turning applications, providing high precision, cost-effectiveness, and adaptability to various machining conditions.

Nowadays, time consuming grindingprocesses are more and more replacedby hard turning operations. Various work piece profiles with smallest tolerances and different surface qualities can easily be machined without further grinding.Furthermore, dry machining is one posi-tive side effect leading to reduction in pro- duction costs. Tungaloy is a pioneer in the productionand development of PCBN and ceramiccutting materials. Already since the early 60ies and 70ies these high performance cutting grades have been produced in- house and successfully applied in variousmachining processes. Our know-how...
