What is Diamond Concentration and which to use for your application

Life of the diamond tool is primarily controlled by amount of diamond crystal in the bon matrix. This amount is called “diamond concentration” higher the diamond concentration a diamond tool has, the longer its life time. The trade off is slower cutting speeds.

AMOND CONCENTRATION - The proportion, and distribution of diamond abrasive particles, also known as concentration. has an effect on overall cutting performance and price of precision diamond blades. Diamond concentration, commonly referred to as CON, is a measure of the amount of diamond contained in a diamond section of drill based upon volume. Diamond concentration is usually defined as: Concentration 100 = 4.4 ct per cm layer volume (mesh size + bond). Based on this definition a concentration of 100 means that the diamond proportion is 25% by volume of diamond layer, assuming at diamond density is 3.52 g/cm3 and 1 ct = 0.2g. Nominal diamond concentration in precision diamond blades range from 0.5 ct/cm3 to 6 ct/cm3. This means diamond concentrations are available from 8 to 135). Selecting the Right Diamond Concentration can be critical in optimizing your Precision Diamond Sawing Operation. Selecting Optimum Diamond Concentration for your application will depend on a large number of factors, such as:

  • Material Being Cut
  • Bond Type and Hardness
  • Separated they live in Bookmarksgrove right attr.
  • Diamond Mesh Size
  • Cutting Speeds
  • Coolants being used

Diamond Concentration will play a major role in determining the life and cutting speed of your High Precision Diamond Blade. Higher diamond concentration is recommended and usually used for cutting softer and more abrasive types of materials. However, the trade off is significantly slower cutting speed. Low diamond concentration is recommended and widely used for cutting ultra hard and brittle materials. Diamond Concentration is usually determined by the the slowest cutting speed that is acceptable for a specific application. Optimum performance can be achieved when the diamond tool manufacturer utilizes their experience and analytical capabilities to balance diamond concentration and other factors to achieve optimum performance for the tool operatorUKAM Industrial Superhard Tools has the experience & applications laboratory to help you select all the right diamond blade variables for your unique application

Example of diamond concentration uses on various applications:

25 – Satisfactory of soft nonabrasive materials. May not be satisfactory where production requirements are high

50 – recommended for most materials and satisfactory in production use

100 – for extremely hard dense materials and where smoothness of  cut and close tolerances must be met.

Diamond Concentration & Cutting Performance

Today, most Production and R & D facilities use low concentration diamond blades for cutting ceramics, glasses, silicon, carbides, sapphire, and other related semiconductor and optical materials. And use high concentration diamond blades on metals such as stainless steel, aluminum, titanium, pc boards. A new technological breakthrough called SMART CUT technology, is making fundamental changes in these beliefs and setting new benchmarks on how diamond blade performance is measured. SMART CUT technology allows the orientation of diamonds inside the metal matrix, so that every diamond is better able to participate in cutting action, By orienting diamonds, SMART CUT™  technology makes diamond concentration only a minor factor in the overall precision diamond equation. Studies and extensive testing shows that diamond concentration in diamond blades manufactured utilizing SMART CUT™ technology plays a no major role in determining overall diamond blade performance. 

Large number of diamonds in a high concentration diamond blade come in contact with material, creating friction, hence considerably slowing down material removal rate. It takes considerable dressing in order to rexpose the next diamond layer. SMART CUT™ technology resolves this problem by making sure that every diamond is in the right place and at the right time, working where you need it most. You get maximum use of diamond and bond. Before this technology was developed, orienting diamonds inside the blade bond matrix was considered impossible. This was one of the main problems faced by diamond tool manufacturers worldwide.  

Over the decades there have been numerous attempts to solve the diamond and CBN distribution problem. Unfortunately, none of the attempts have been proven effective. Even today 99.8% diamond blade manufacturers still have no way or technology to evenly control and distribute Diamond or CBN particles inside bond matrix, nor properly position them to maximize their machining efficiency.

Diamond Concentration & CBN (cubic boron nitride) blades

For CBN (cubic boron nitride) concentration is defined by volume. For example V120 = 12% by volume, V180 = 18% by volume.
