Overview

KOVES PCD (Polycrystalline Diamond) blades are precision cutting tools designed for machining non-ferrous metals and various non-metallic materials. Manufactured by welding high-quality PCD under high temperature and pressure onto a superior hard alloy substrate, these blades offer exceptional durability and versatility for turning and milling operations.

Material Grades and Characteristics

• KPD10: Fine-grained PCD material with grain size of 10 μm, offering high precision and suitable for non-ferrous metals such as high silicon aluminum alloys, purple bronze alloys, rubber, wood, and graphite. It has a bending strength of 10,000–12,000 kgf and hardness of 200 Hv.
• KPD05: Ultra-fine grain (5 μm) PCD material that produces sharp cutting edges, ideal for finishing plastics, wood, and aluminum alloys. It has the highest hardness (220 Hv) and bending strength similar to KPD10.
• KPD25: Coarse-grained (25 μm) PCD material with excellent wear resistance, suitable for rough machining of high silicon aluminum alloys, cemented carbide, ceramics, rocks, and stones. It has a hardness of 110 Hv and similar bending strength.

Applications

The PCD blades are optimized for machining:

• Aluminum alloys with varying silicon content (4%-18%)
• Red copper and bronze alloys
• High-strength plastics
• Wood
• Cemented carbide
• Non-alloy materials such as ceramics, stone, rubber, graphite, and wood

Recommended Cutting Conditions

Insert Types and Dimensions

The document lists various insert designations (e.g., TNMM, VNMM, WNMM, MGMN, AP, SE, GBA, WBMT) with corresponding dimensions such as inscribed circle diameter, thickness, nose radius, and hole diameter. Both negative and positive insert types are available to suit different machining requirements.

Safety and Usage Recommendations

• High temperatures and long chips may be generated during machining; always use machine guards, safety goggles, and protective covers.
• When using non-water soluble cutting oils, fire safety measures including automatic fire extinguishing devices should be in place.
• Handle blades carefully due to sharp cutting edges.
• Use the tools strictly within the recommended cutting conditions to avoid tool breakage or flying debris.
