PCD BENEFITS

Our PCD diamond blanks offer a combination of high hardness, abrasion resistance, low friction, and impact resistance. These blanks feature a tungsten carbide substrate that provides mechanical support to the diamond abrasive layer, boosting impact strength and enabling easy braze attachment during tool fabrication.

Widely used in machining non-ferrous and non-metallic materials, PCD cutting blanks have become the global industry standard for superior part quality and significant cost reductions throughout the production cycle.

Unlock the following advantages by incorporating PCD cutting blanks into your
machining process:

-> Achieve higher material removal rates and optimized cycle times, resulting in increased parts per shift.
-> Experience cutting speeds that surpass those of traditional cutting tools, enhancing overall productivity.
-> Attain exceptional workpiece quality with precise dimensional control, consistent surface finishes, and reduced scrap.
-> Enjoy longer tool life, leading to improved machine uptime and increased production capacity without the need for additional equipment investment.
-> Discover the power of PCD cutting blanks and elevate your machining capabilities to new heights.
