For Hydraulic Parts / Super Sizing Reamer
Lens Mold, Optical
Highly Precise Hole Finishing by 1 Pass "Super Sizing" is a superabrasive electroplated reamer that can be done with "highly precise," "high quality" and "highly efficient" finishing of holes of various parts. In hole finishing method such as honing, milling, fine boring and internal grinding, major problems such as poor machining accuracy or inconsistency of diameter can be resolved by "Super Sizing." ・Easy to maintain accuracy in severe hole tolerance grinding. ・Possible to obtain good surface roughness with high grinding accuracy. ・Highly efficient grinding by 1 pass. ・Minimized rounding of affected areas in finishing oil holes, notches and holes with keyway. ・Continuous automated operations (skill-less). ■Features ・Finishing holes of cast iron hydraulic components and automotive components ■Applications
Cemented Carbide Lens Molds / Ultra-Precision Cutting Tool BLPCD UPC
Achieves Long Tool Life in Mirror Finish and Fine Machining of Carbides "SUMIDIA Binderless" is the new material that has been developed by Sumitomo Electric Industries, Ltd. Ultra fine particles in size of several tens of nanometers have been bonded firmly without the use of binding material, providing hardness that exceeds signal crystal diamond. Also there is no crystal anisotropy and cleavage. We have combined this material with our strong point, diamond precision polishing technology, to realize the tool that is very strong against chipping more than ever and long tool life.
■Features
【Features of SUMIDIA Binderless】 ・Fine grains of several tens of nanometers are firmly and directly bonded together without binder.
・Harder than single crystal diamond. ・No anisotropy and specific cleavage.
・Molds for carbide glass lenses, Machining of other high-hardness and brittle materials ■Applications ・Sharp and precise cutting edge equivalent to UPC (Single crystal diamond). ・Free from uneven wear caused by crystal orientation due to no anisotropy. 【Features of BLPCD UPC】 ・Superior chipping and wear resistance compared to single-/poly- crystal diamond.
For Polygon Mirrors for Copier Photosensitive Drums / Ultra-Precision Cutting Tool UPC-F
Excellence in High Efficiency and Ultra-Precision Cutting of Planes and Cylinders Drastically reduces or dispenses with running-in processing time. You can obtain uniform, high-quality worked surfaces by setting the roundness (sharpness) of the cutting edge according to the work material and processing conditions.
■Sharp Cutting Edge Equivalent to Single Crystal Diamond
■Flank Wear Comparison of Machined Carbide
・Good burnishing effect can be achieved and highly efficient mirror finishing is possible. ・Ultra-precision polishing technology has realized very sharp cutting edges. ■Features ・Plane and cylindrical mirror finishing of polygon mirrors for copier photosensitive drums, Laser reflection mirrors ■Applications ■Dimension and Highest Accuracy Type
■Cutting Edge Exclusive Edge for Polygon Mirrors
