超硬合金・硬脆材加工用 UDCシリーズ

In 2012, we launched diamond coated end mills for processing cemented carbide. This series is applied UDC (Ultra Diamond Coating), which offers excellent hardness and durability by improving adhesion to cemented carbide and controlling fine particle composition, and literally 'cuts' cemented carbide stably with long tool life. Furthermore, the best-designed tool geometry for processing cemented carbide makes remarkable DEEP cutting possible and achieved highly efficient and accurate processing of cemented carbide.

New multi-flute radius type!

Newly released UDCRRS multi-flute radius end mills from our UDC series for milling cemented carbide.
The 6 to 10 flutes and the 40 degree helix angle achieves low cutting resistance and offers deep cutting depth milling!Compared to the 2 flute models, the efficiency has been dramatically increased!
This contributes to the reduction in cycle time.

 Features of UDC-H (High speed) series

UDC-H (High speed) series is the long-awaited UDC 3rd generation series with an optimized cutting edge treatment and improved diamond coating with respect to the “F series”. We can achieve high feed rates that up until now could not be dreamed of when imagining the direct milling of cemented carbide. The material removal volume has also dramatically increased, and this is ideal for rough processing to semi-finishing. By using it in conjunction with the previously launched “F” (Fine) series, it is possible to perform direct milling of cemented carbide with both high efficiency and high quality.

CBN Series

A new long neck ball CBN-PLB for super mirror surface processing has been added to the CBN series. The unique tip shape maximizes the burnishing effect and enables super mirror surface processing as opposed to the conventional series!The slot design that allows the coolant to reach the cutting edge improves the chip evacuation performance as well as preventing biting, which ensures the longevity of the mirror surface.

CBN series for super finishing

Long neck ball CBN-LBSF and long neck radius CBN-RSF series designed for super finishing can obtain a better finished surface as opposed to conventional products due to the characteristic flute shape that achieves a burnishing effect. Recommended for the finishing of high hardness materials that emphasize the finished surface.

CBN-LBSF Features of tip shape


CBN-LBSF Features of tip shape

A cutting edge has been added to the tip of the tool (Zero peripheral speed point)
Suppresses tool damage and improves the finished surface!

CBN-RSF Burnishing effect at the flute tip (ELMAX 60HRC)


CBN-LBSF Features of tip shape

Optimizing the width of the burnishing surface that rubs on the machined surface, will give a glossy surface and achieves a super surface finish!

Features of long-life CBN series

Optimized cBN material and improved cutting edge geometry for milling the ultra-hard materials offer high precision milling and long tool life.
By excellent wear-resistance and chipping-resistance of the tool, outstanding surface roughness and precision are maintained even under long cycle time. Recommended to use on finishing process for the ultra-hard materials.
