Vitrifided CBN Wheel for Shaft Grinding Vitrifided CBN Wheel (削楽～SAKURA～)

Currently, we are required high grinding efficiency and tool cost reduction when processing hardened materials such as automobile parts. "-SAKURA-" achieves improved sharpness (reduction of grinding resistance) after truing by renewing the composition of CBN abrasive grains, bonds, and fillers, which are the main components of the CBN layer. As a result, we provide ease of use such as stable shape accuracy and stable grinding time in addition to long-life wheel performance.

Vitrified CBN Wheel for Shaft Grinding Tough Premium III

This vitrified CBN wheel was designed for ease of use (machining precision, burn, and residual stress). To improve the problem of reduced cutting performance immediately after truing that ordinary vitrified CBN wheels are prone to, the thermal resistance of the binder has been enhanced, with improvement achieved by adjusting the compounding quantities. Changes in wheel wear and roughness equivalent to the Tough Premium II can be expected.

Vitrified CBN Wheel for Cast-iron Grinding Tough Premium III

This vitrified CBN wheel was developed for specialized use in cast-iron cam grinding through high-efficiency grinding. The binder for the Tough Premium III for shaft grinding is used, with effort also devoted to optimizing the structural components. The decrease in roughness is slow and wear is also low, which can help enhance tool cost performance.

Vitrified CBN wheels having truing intervals as long as three times those of existing series products make it possible to reduce the tool cost, improve the grinding accuracy and reduce the grinding time. Stiff CBN grains extending the service life of the cutting edge, strong vitrified bonding agent having a good affinity with grains, and innovational distribution technology serve as key technologies in the improvement of the cutting performance as well as the service life.

CBN grains having superior cutting performance and improved grain bonding force are key technologies in the improvement of cutting performance and service life of this resin wheel. The service life is extended to twice and the flatness is improved by 30% in double head surface grinding when compared with those of earlier models. The service life is beyond 2.5 times that of existing models in through-feed center-less grinding.

Ulteel

Automotive and Transportation Equipment

A resin-based bonding material is used to increase resilience, working softly on the workpiece. Because the cutting performance is superior while generation of chipping and cracks is fewer, the product is used for applications such as the grinding of hard and fragile materials and tool grinding where the sharp cutting edge is needed. It is also used for the grinding of cemented carbide and ceramics.

Metal wheel Teramate (MT3)

Due to its toughness, metal wheels are often used for high-efficiency grinding in the fields of tools and dies, ceramics and aerospace. By adjusting the filler and abrasive grain type of our new metal wheel (MT3), dressability has improved by 2.7 times compered to conventional products, and the grinding performance is improved.

Metal Wheel for Grinding Difficult-to-cut Materials Teramate MT2

Metal is used for the binder. Optimizing the abrasive-grain type, reduction of low friction due to bond microfracture, and a suitable amount of wear make for superior grinding performance in high-efficiency regions compared to the Teramate (resin bond). This is applicable for grinding Inconel.

Ultra-mate

Metal bond wheels offer excellent heat resistance and thermal conductivity and can serve for many years to come because of the metal used as a bonding agent. However, they are inferior as to the ease of truing and dressing and sharpness compared to resin bond wheels. Ultra-mate is a metal bond wheel using a special lubricant to cover this disadvantage.

Grains of diamond are fixed by an electroplating method. Reverse plated method rotary dressers suffer little thermal strain because the manufacturing of reverse plated method dressers does not involve high-temperature processes. Reverse plated method rotary dressers are suitable for fine, complicated shapes and shapes requiring high accuracy.

Reverse plated method-DD type
