PCD tool Regrinding/Resharpening

In order to help customers to make a further decreasing in the production cost,  and also to protect the environment and recycle the non-renewable resources, Project PCD Grinding from MORESUPERHARD supply provide regrinding/resharpening service for PCD/CBN/ND/CVD/MCD tools, especially for complex tools which is edge broken or not sharp.



PCD Tools Resharpening/Regrinding

What is tools resharpening?

Tools resharpening is a process of renew your old tools by cutting or grinding. It gives your old tools new life with low cost in a short time.

Why resharpening PCD tools?

Simply, it saves your money. When your tools are dull, broken, or running out of precision, resharpening them is a better option than throwing them away. It saves your 20% -- 75% cost depend on different PCD/PCBN/MCD/ND/CVD tools. And it also saves your time than buying a new tool.

Which tool is good to resharpen?

The simpler the tool, the better it is to regrind.

The Design, coating, complexity, application and the price of the tool are all determined a tool whether worth to regrind or not.


What is advantage of PCD tools regrinding?

√  Save your money.

√  Properly PCD tools regrinding can greatly extend the working-life of tools.

√  Improve the precision of tools.

√  It is a green option, it protects the environment and recycle the non-renewable resources.

How MORESUPERHARD    resharpen the PCD tools?

We choose the most suitable diamond wheels, usually the 1000-3000# grit wheels to get a allowed chipping, maybe 7μm or 5 μm,usually the normal PCD tools can be resharpened 2-3 times.

When can’t resharpening?


If the size and the radius can’t get your requirement after times resharpening, we can reset/retip the new PCD tips on the cutting tools. If it's just dull (edge breakdown) and you can stand to lose diameter, a regrinding to get back to solid edge diamond is mostly just labor and grinder time.

If the edges are in pretty bad shape or you can't lose diameter then the pcd needs to be shifted out in the pockets and then reground. Lot more labor intensive and can only be done 3-4 times before the PCD substrate gets cracked from heat cycles.

If they are busted up or chipped really bad then new segments have to be wire cut and brazed on the shank.


Case study
Workpiece material: carbide + PCD (element six)
Blade model: DCGW
Requirements for chipping after grinding: <0.01
Grinding wheel specification: 6A2, D150*H40*T40*W5*X10
Granularity: 800#, 3000#, 4000#
Feedback: The appearance of the grinding wheel is good, the chipping of 3000# (D3) is 0.01-0.02 after grinding, and the requirement is met after 4000# grinding
