“DEX Duo” Electroplated Wheel for Hard Brittle Materials
“Gran DEX” Electroplated Wheel for Hard Brittle Material
■ Abrasive grain intervals are widened by controlling the abrasive grain density in the electroplating. This can reduce grinding resistance during rough grinding of hard, brittle materials such as glass or ceramics, and realize high-level cutting performance even in deep grinding.
■ Life of the wheel is extended significantly with tipping and surface roughness maintained at the same level as in conventional electroplated wheels.
■ Clogging can be reduced by widening the abrasive grain interval.
“Chemex” Resin Bond Wheel for Wafers Polishing Grinding
“Chemex” resin bond wheel realizing fixed abrasive in silicon wafer polishing
■“Chemex” wheel uses chemical action together with mechanical action to realize fixed abrasive polishing instead of conventional loose abrasive polishing.
■The target is to achieve high-quality surface like slurry.
■Wheels of the structure most suitable for work material or purpose can be proposed.
“VEGA” Porous Vitrified Bond Wheel for Wafers Finishing Grinding
Higher surface roughness realized by intermediate processing and final processing of silicon and SiC wafers
■Higher surface roughness is realized by the combination of ultra-fine diamond abrasive grains and vitrified bonds of large and fine porous combination structure.
■Spontaneous blade generation is realized and cutting quality is maintained by bonds that can make ultrafine shredding.
■Stable high-quality surface and low processing cost can be realized.
Diamond wheel for chamfering glass substrates
“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
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
“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.
