Electroplated grinding pins are precision internal grinding tools designed for high-accuracy machining of small bores. They consist of hardened steel shanks coated with a single layer of superabrasives - diamond or CBN (Cubic Boron Nitride) - through an advanced electroplating process.
These grinding pins deliver superior cutting efficiency, form stability, and long service life in the most demanding grinding operations.
Abrasive Types & Suitable Materials
1. Diamond Grinding Pins
Diamond is the hardest known abrasive, ideal for non-ferrous and brittle materials.
Recommended for grinding:
• Cemented carbide
• Cermet
• Advanced ceramics
• Quartz, glass, and optical materials
• Ferrites, graphite
• Semiconductor substrates
• Glass fiber reinforced plastics
2. CBN Grinding Pins
CBN is the second hardest abrasive, specially engineered for ferrous materials. Unlike diamond, CBN does not react with iron, making it the best choice for steel grinding.
Recommended for grinding:
• Hardened steels (HRC > 45)
• High-speed steels (HSS, e.g., M2, M3)
• Tool steels (D2, A2, etc.)
• Stainless steels
• Stellite and cobalt-based hard alloys
• Nickel-based and heat-resistant super alloys
• High-alloy, difficult-to-machine steels
Key Advantages
• Precision: Centerless ground hardened shanks (42~55 HRC) ensure high concentricity and stability.
• High cutting performance: Exposed abrasive layer delivers aggressive, consistent material removal.
• Form retention: Ideal for tight-tolerance bores.
• No dressing required: Electroplated layer maintains shape throughout the tool life.
• Customizable: Available in various head sizes, shank diameters, grit sizes, and lengths.
Applications
Electroplated Diamond & CBN Grinding Pins are widely used in:
• Jig grinding and internal grinding machines
• Cylindrical grinders and rotary hand tools
• Die and mold machining
• Tool and cutter manufacturing
• Aerospace and automotive part finishing
• Medical device manufacturing
• Wire drawing die finishing and tubing industry (taper pins)
Electroplated diamond and CBN grinding pins provide high-performance solutions for internal grinding of a wide range of materials - from ultra-hard carbides and ceramics to tough hardened steels and super alloys. With excellent form stability, exceptional cutting action, and long service life, these tools are essential for achieving precision and productivity in modern manufacturing.
