・Multi-Step profile tools consolidate the hole finishing process. ・Achieve precise and stable accuracy by utilizing the characteristics of diamond material with sharp edges and abrasion resistance. ・Combining the optimal design and machining conditions can improve accuracy and machining time. ■Features Aluminum parts for powertrain applications are becoming more complex in shape and getting thinner for improvement of fuel efficiency and lightweighting.

For Finishing Valve Guide Hole / PCD Rotating Tool

For Machining Steering Parts / PCD Rotating Tool

Aluminum parts for steering housing must be not only lightweight, but also labor-saving and highly functional. There are many machining areas and its shapes are becoming complex as numbers of sensors and assist devices are incorporated. Therefore, productivity improvement by machining time reduction is required. We contribute to productivity improvement by realizing high quality machining at high feed rates through our unique tool design and process-integrated design. ・We propose designs that take into account weight reduction and dynamic balance, since large-diameter hole finishing is often required. ・Process integration can be expected through multi-step hole finishing and design combining different cutting tools, such as taps. ■Features

Valve guides are made of sintered alloy or cast iron from the viewpoint of sliding properties and durability of the valve shaft moving at high speed. Finishing valve guide holes with carbide reamers hinders productivity due to low wear resistance, which deteriorates machining accuracy and causes frequent tool changes. On the other hand, diamond reacts with iron, but by reducing the machining speed, it can be applied and the issues (machining accuracy and productivity) that cemented carbide reamers face can be cleared. We will propose blade design suitable for the required grade and machining conditions. ・PCD with excellent abrasion resistance is used to achieve stable processing quality. ・We propose the design of a cutting tool suitable for the quality of the workpiece. ■Features

Achieves Stable and Long Tool Life by Measuring and Optimizing the Crystal Orientation The optimum crystal orientation of diamond is set with high accuracy, and it is rigidly bonded to cemented carbide of unique shape. A combination of the original shape tip and holder facilitates the setting of the tool accurately as with throwaway tips. The tips are designed for linear cutting and curved cutting and the profile accuracy of the tip for profile curved cutting is 5 µm. No chips will be fused or deposited on the rake face to keep producing high quality surfaces even during continuous operations. ・Automotive components (Pistons, Aluminum wheels, Compressors, Commutators, etc.) ・Plastic lenses, Resin parts ■Applications ・Less dispersion in tool life, which is a weakness of single crystal diamond tools, and 1.5 to 2 times longer tool life than conventional tools on average. ・The combination of our originally-designed inserts and holders enables easy and precise tool setting like indexable inserts. ・There are inserts for straight cutting and those for curved-surface copying. The form accuracy of the latter is 5 µm. ・The rake face is free from adhesions and accumulation of chips and maintains the high quality of worked surfaces even during continuous use. ・Exhibits high durability even during interrupted cutting. ・Unlike the conventional type with a retaining cap, there is no retaining cap to hold the diamond, enabling chips to move smoothly on the rake face, improving the machining accuracy. ■Features

・Dressing of worm-shaped grinding wheels used for generating the tooth form of automotive and machine gears ■Applications ・Extremely high tooth profile accuracy of 0.001 mm or less can be obtained. ・High ability to maintain tooth profile accuracy shape and low dresser life variation contribute to reduced grinding costs. Contributes to Higher Quality Gears and Reduced Grinding Costs As a dresser for shaping worm-shaped grinding wheels used in gear grinding, it realizes "higher precision gears" and "reduced grinding costs" by extending dresser life. ・Based on information such as workpiece gear specifications, grinding wheel shape and specifications, we design a dresser that achieves the required tooth surface quality. ■Features
