High-Wear Resistance Brazed Diamond Grinding Disc: Hole Diameter and Edge Thickness Selection Guide

Choosing the Right Diamond Grinding Disc Size for High-Wear Applications

When working with tough materials like stainless steel, hardened alloys, or gray cast iron, selecting the correct 180mm brazed diamond grinding disc is critical—not just for performance, but for safety and efficiency. At UHD (Henan Youde Superhard Tools Co., Ltd.), we’ve engineered a range of customizable options that go beyond standard specs to meet real-world machining challenges.

Why Diameter & Edge Thickness Matter in Real-World Use

Many buyers overlook how small changes in disc geometry can dramatically impact tool life and surface finish. For example:

• 180mm diameter: Ideal for CNC grinding machines and handheld tools requiring high torque and precision—especially in aerospace and automotive component manufacturing.
• Edge thickness options (3mm–8mm): Thinner edges (3–4mm) offer better cut quality on fine surfaces; thicker ones (7–8mm) increase durability under heavy load—up to 30% longer lifespan in abrasive applications.

Our proprietary brazing process uses a copper-tin alloy that bonds diamond segments directly to the steel base without weakening the structure—a method proven in over 1,200 industrial installations worldwide. This ensures consistent heat dissipation and prevents chipping even at speeds above 3,000 RPM.

Real-World Impact: A Case from the Automotive Sector

A German Tier-1 supplier reduced their grinding cycle time by 18% after switching from fixed-size discs to our custom-configured 180mm models. By choosing a 6mm edge thickness and optimizing hole size (25.4mm center bore), they achieved smoother finishes on hardened crankshafts while cutting tool replacements by nearly half per month.

This isn’t just theory—it’s what happens when you match material properties with smart design.

Frequently Asked Questions (FAQs)

Q: Can I get a disc with non-standard hole sizes?

A: Yes—we support custom center holes from 16mm to 40mm based on your machine requirements. Most OEMs request 25.4mm or 30mm for compatibility with existing spindles.

Q: How do I choose between thin and thick edges?

A: Thin edges (≤4mm) are best for finishing cuts on stainless steel; thick edges (≥6mm) excel in roughing operations on hard metals like tungsten carbide.

Q: Do I need special maintenance for these discs?

A: Not really—if used within recommended RPM ranges and cooled properly during operation, our discs maintain sharpness up to 200 hours of continuous use before reconditioning.
