Why Diamond for Precision Machining?

Diamond is the hardest naturally occurring substance on Earth, making it an exceptional choice for industrial machining applications. Its unique properties enable unparalleled shaping accuracy, superior surface finishes, and outstanding performance across a wide range of materials.

Things to Consider When Choosing a Diamond Tool

1. Selecting the right diamond tool depends on several key factors. The first step is understanding the material you’ll be working with. Different materials demand different tool characteristics—and some materials may not be compatible with diamond at all.

2. Equally important is knowing the end result you want to achieve. Surface finish, tolerances, and cutting depth all play a major role in determining the most suitable tool.

Ask yourself these questions to guide the selection process:

·  What machine tool will be used?

·  What is the workpiece material?

·  What is the desired shape of the end product?

·  What depth of cut is required?

·  Does the finished product need to be optical quality?

·  What level of waviness is acceptable?

·  Are micron or submicron tolerances required?

The more information you have about your application, the easier it is to identify the perfect diamond tool. If you’re unsure or would like expert guidance, simply reach out to our team using the buttons below—we’ll be glad to help you make the right choice
