Product List

These metal bond wheels are designed with a new concept, and have both the high cutting performance of resin bonds and the abrasion resistance of metal bonds. They are suitable for efficient grinding of difficult-to-cut materials such as Al2O3-TiC and quartz.

Diamond metal bond wheels with spindle are specially designed for machining hard and brittle materials.
We offer the most suitable bond specifications for various materials in the grinding process of hard and brittle materials using a machining/gliding center.
The metal bond wheel has high abrasive grain retention and high sharpness even when machining hard materials. It also has good thermal conductivity, which prevents heat buildup at the machining point and prevents thermal cracking of brittle materials. The tool life is longer than that of electrodeposition tools with a single diamond layer, and it is the best tool for machining ceramics, especially hard SiC and aluminum nitride.
In the machining of quartz glass, the optimum bond selection ensures high grinding durability.

This wheels is used for forming / grooving of fine ceramics, quartz and other hard brittle materials and high-speed steel, and chamfering of glass substrates.

The "MB" bond series is a resin bond wheel with high shape retention using heat-resistant resin and metal filler. It has high sharpness and high shape retention in heavy-duty grinding with a large depth of cut.
The ability to form by electrical discharge machining makes it possible to form differently shaped abrasive grain layers, which are usually difficult to form, making this bond very suitable for machining with formed tools in plunge grinding.


The "MB" bond series is a bond that works well with both diamond and CBN wheels.
The diamond wheels are suitable for machining with formed tools for quartz, ceramics, and cemented carbides.
CBN wheels are suitable for the machining of high-speed steel blades and for machining with formed tools for iron-based machine parts that require high accuracy.
Since the wheels are heat resistant and capable of heavy-duty grinding, we have experience in machining with formed tools using multi-wheels that combine several wheels.

"BL" porous resin bond wheels are designed for mirror grinding of cemented carbide / tungsten carbide molds, ceramics, silicon wafers, and hardening steel alloys. With the effect of pores and a heat-resistant bond strengthened by special filler, these wheels produce high quality finished surfaces while maintaining their cutting performance.

■ Single-piece formation of a resin bond wheel with a maximum outer diameter of φ600mm and width of T100mm can be realized.
■ Grinding trace at joint is eliminated.
■ Dynamic balance of 0.1μm is realized for products with a dedicated flange.

High-quality finishing is realized by electroplating fine abrasive grains of around #1000～#2000.
■ High-quality finishing is realized with good surface roughness and less tipping.
■ High ability of maintaining the wheel shape realizes high-precision shape forming.
■ Multi-layered electroplating can be conducted to extend the life of the wheel.

■Realizing persistence of the grinding performance of the diamond abrasive grains and longer tool life.
■The long tool life stabilizes the processing quality.

Diamond mounted V-face wheels are tools mainly used for aspherical surface machining of glass lens molds.
For plastic lens molds, nickel is machined with an ultra-precise single-crystal diamond cutting tool, while ultra-fine binderless cemented carbide is used for glass lens molds.　In addition, demand for SiC molds has been increasing recently.
For the machining of such binderless cemented carbide and SiC lens molds, grinding with a diamond wheel with shaft is used because cutting with a single-crystal diamond cutting tool is unsuitable and inefficient.
We have extensive experience with single-crystal diamond cutting tools for plastic lens molds, and also offer various specifications of diamond mounted wheels for glass lens mold machining.
In addition to V-face shaft wheels, we also offer cylindrical small-diameter shaft wheels for diagonal grinding, free-form grinding, dressing, and sleeve mold machining.

This is a mono-crystal diamond radius cutting tool with a cutting edge waviness of 50 nm or less. It realizes high-precision machining, thus reducing mold production processing requirements. Due to its fine rake and clearance surface, it can elicit better performance of a 3-axis machining device and improve the copying performance of molds. It also realizes high-precision machining by a 2-axis machining device.
 

[Typical applications of highly contoured mono-crystal diamond cutting tools]
