Diamond wheel for chamfering glass substrates

Diamond wheel for chamfering glass substrates

This chamfering wheel is designed to maintain substrate strength when fabricating glass display panels. Wheels for facilitating high-speed substrate feeding are available for various machines.

Diamond wheel for forming hard brittle materials

Diamond wheel for forming hard brittle materials

The "MF50" metal bond wheel is used for fine ceramics forming, glass substrate chamfering, and the forming of other hard brittle materials. Its advantages include high cutting performance and low grinding noise.

“DEX” diamond wheels for chamfering glass disks

“DEX” diamond wheels for chamfering glass disks

These wheels are used to chamfer the inner diameter (ID) or outer diameter (OD) edge of glass disks. Due to the special electroplating used in this design, the roughness of chamfered surfaces are improved and chipping at the boundary area to the edge surface is minimized. Wheels using micron size abrasive grain are available.

“DEX” diamond wheel for optical lens centering

“DEX” diamond wheel for optical lens centering

This wheel is used for axis alignment (optical lens centering) of aspherical lenses or steppers used in high-grade cameras or endoscopes, which usually require high-precision grinding. When used, pre-conditioning grinding is not necessary and lens manufacturing with less damage on the lens edge starts from the beginning of processing work. The wheel can also suppress lens coloring, even when a steep rise shape is used.

“DEX” diamond wheels for forming difficult-to-cut materials

“DEX” diamond wheels for forming difficult-to-cut materials

These wheels are designed for high shape precision forming of, for example, motor cores. Wheels of the most appropriate specifications are available for not only magnetic materials such as neodymium-iron, but also for ferrites, ceramics and glass.

“Lenelas” diamond high-elasticity wheel for finishing

“Lenelas” diamond high-elasticity wheel for finishing

This wheel has high abrasion resistance because it uses a high-elasticity resin bond made with a special bonding agent. It realizes surface roughness of the same level as final lapping or polishing in a short period of time. By varying the bond content, it can be used to process different materials such as glass, metal, and ceramics. There are two types of bonds available: "RN" bond for better grinding performance and "RP" bond for better surface roughness.

Diamond multi-layer wheels

Diamond multi-layer wheels

A single wheel of this type can perform multiple grinding processes such as rough grinding, pre-finishing, and finishing. This allows multiple processes to be performed with a single machine without replacing tools, which reduces processing time. Multi-layer wheels with a combination of metal bonds for rough grinding, resin bonds for pre-finishing, and resin bonds for finishing are available.

Diamond mounted wheels for interior grinding of hard brittle materials

Diamond mounted wheels for interior grinding of hard brittle materials

There wheels are used for the internal grinding of precision parts as well as the precision grinding of glass, ceramics, carbon, ferrites, and gemstones. Wheels with bonds and specifications most appropriate to materials and usage can be provided.

Small diameter diamond mounted wheels

Small diameter diamond mounted wheels

These wheels can be used to drill clean holes or expand existing holes in hard brittle materials such as cover glasses with a strengthened layer. For thin glasses, machining efficiency can be improved by simultaneously drilling a number of glass plates arranged in a stack.

Diamond double core drills

Diamond double core drills

These core drills are commonly used to simultaneously machine the inner and outer diameters of the glass or ceramic disks used for hard disk drives. Their usage contributes to the shortening of machining time.
