FAQ

Frequently asked questions are summarized below. If you do not find a question, please feel free to contact us.

What kind of abrasive grain evaluation do you perform?

In addition to general grain size control, we conduct quality control using our own know-how on coarse and fine grain control, as well as quality control using various inspection machines including shape and composition.

Is it possible to make custom orders for diamond/cBN powder?

We have been responding to custom orders from customers since our establishment, including specification of grain size and shape and additional processing of abrasive grains. We will make use of our strength as a manufacturer to offer various proposals.。

Is it possible to respond to custom orders for sintered diamond/cBN?

We are working on various custom orders as a manufacturer, such as changing the composition and shape of abrasive grains as well as the overall thickness and the thickness of diamond and cBN layers. Please contact us first.

Is it possible to provide samples?

Depending on the type, we can provide samples. Please feel free to contact us.

What is the minimum sales unit for diamond powder and cBN powder?

It may vary depending on the product, but generally, the smallest unit we handle is 100ct (20g). For more details, please contact us.

How long does it take for delivery?

If the item is in stock, it can be shipped in one to two days. If the product is not in stock, the delivery time varies greatly depending on the product, so please contact us first.
