How to Choose the Right Diamond Mounted Point for Your Application

Introduction

In precision machining, tool selection plays a critical role in achieving accuracy, efficiency, and cost-effectiveness. Among the many abrasive tools available, diamond mounted points stand out for their ability to deliver superior grinding, shaping, and finishing performance on hard and brittle materials. These small yet powerful tools are widely used across industries such as aerospace, automotive, electronics, toolmaking, and medical manufacturing.

At Sea Shore Diamond Industrial Co., Ltd. (SSDC), we understand the challenges manufacturers face in balancing speed, accuracy, and durability. That’s why we provide a wide range of diamond mounted points engineered to meet the specific needs of modern machining. In this article, we’ll guide you through how to choose the right diamond mounted point for your application—helping you make informed decisions that enhance performance and productivity.

What Are Diamond Mounted Points?

Diamond mounted points are small grinding tools that consist of a metal shank with a bonded diamond abrasive head. They come in various shapes—such as cylindrical, ball, cone, or tapered—making them versatile for fine grinding, deburring, polishing, and edge finishing.

Unlike conventional abrasives, diamonds provide exceptional hardness and wear resistance, enabling efficient cutting on materials such as:

• Tungsten carbide
• Ceramics and glass
• Hardened steels
• Quartz and other brittle substrates
• Composites and advanced materials

Their compact design makes them especially suitable for intricate work, such as tool finishing, mold polishing, and micro-machining tasks.

Factors to Consider When Choosing a Diamond Mounted Point

1. Material Being Processed

The workpiece material directly influences the choice of grit size and bond type. For example:

• Carbide and hardened steels require finer grit sizes for precision shaping.
• Glass, quartz, and ceramics benefit from medium grit for efficient stock removal with reduced risk of cracking.
• Composites or softer metals may require coarser grit to optimize cutting speed.

2. Shape and Profile of the Mounted Point

Different shapes allow access to different areas:

• Cylindrical points are ideal for flat surfaces and slot grinding.
• Ball or spherical points excel in contouring and internal radii.
• Cone and tapered points are used for edges, narrow grooves, or chamfering tasks.

Selecting the right shape ensures the tool matches the geometry of the part, reducing processing time and improving accuracy.

3. Grit Size

The grit size determines the surface finish:

• Fine grit (higher numbers) achieves smooth finishes for precision parts such as medical implants or electronics.
• Coarse grit (lower numbers) is better for aggressive material removal, such as rough shaping in toolmaking or construction applications.

4. Bond Type

Diamond mounted points can be manufactured with different bonding systems:

• Resin bond: Provides flexibility and smooth finishes, excellent for polishing delicate surfaces.
• Metal bond: Offers durability and high wear resistance, ideal for heavy-duty tasks.
• Electroplated bond: Ensures sharp cutting edges with a single diamond layer, suitable for high-precision tasks and intricate grinding.

5. Machine Compatibility and Speed

Always match the mounted point with the spindle speed and machine type. Over-speeding can cause premature wear, while under-speeding may reduce grinding efficiency.

Applications of Diamond Mounted Points

Diamond mounted points are used across industries where precision and reliability are non-negotiable:

• Aerospace: Machining turbine blades, precision engine parts, and composite components.
• Automotive: Finishing hardened steel gears, injection nozzles, and brake components.
• Electronics: Grinding semiconductor wafers and polishing miniature parts.
• Medical Industry: Producing dental burs, surgical tools, and orthopedic implants with strict tolerance requirements.
• Toolmaking: Sharpening carbide tools and refining molds for mass production.
• Glass & Ceramics: Edge finishing, engraving, and polishing of delicate materials.

Their versatility makes them indispensable in any industry requiring micron-level accuracy.
