諏訪機械製作所 List of Products and Services

Our double-sided grinding and lapping technology does not use magnets for workpiece fixation; instead, it performs grinding and polishing by sandwiching the workpiece between upper and lower rotating grinding stones. This allows us to accommodate various materials, including non-magnetic materials and difficult-to-machine materials. For exterior components of food packaging machines, we perform machining after flat grinding to ensure flatness. In the processing of mirror components for medical devices, we use a combination of grinding and lapping to achieve a thickness of 1mm in brass material. Please leave the polishing and mirror finishing of SUJ2, aluminum, stainless steel, and difficult-to-machine materials to us. 【Examples of main processable materials】 ■ Aluminum: General aluminum materials such as A5052, A5056, A5083, A5454, etc. ■ Stainless steel: General stainless steel materials such as SUS304, SUS410, SUS430, etc. ■ Carbon steel: SK materials, S45C ■ Iron: FCD (spheroidal graphite cast iron), SUJ2, SS400, S390, SS490, SS540, etc. ■ Copper: C1020P (oxygen-free copper), C1100P (tough pitch copper) ■ Resin: pp, peek, pps, bake, pet, etc. *For more details, please refer to the PDF document or feel free to contact us.

"Precision Double-Sided Grinding" is a technology that simultaneously grinds a workpiece from both the top and bottom using a disc-shaped grinding wheel. By applying pressure from above and below, it suppresses warping of the workpiece and maintains high precision in flatness and parallelism. It achieves a thickness accuracy of ±5μ, flatness of 10μ, and parallelism of 5μ. The surface roughness can be finished as specified, and it also achieves high-quality finishes such as mirror surfaces. Since it is not a magnetic chuck, it can process non-magnetic materials as well. [Features] ■ Capable of grinding difficult-to-machine materials and non-magnetic materials such as Inconel, Invar, titanium, Kovar, ceramics, and copper. ■ Numerous processing achievements for products with high flatness and parallelism requirements (achieved flatness and parallelism of 5μ). ■ Achieves stringent surface roughness that is difficult with milling (Ra0.1 and mirror finishes). ■ Numerous processing achievements for products with high thickness accuracy requirements (achieved ±3μ). *We are currently offering a PDF document showcasing our processing achievements for automotive and aerospace components. Please feel free to contact us for inquiries.

Our double-sided grinding and lapping technology does not use magnets for workpiece fixation; instead, it grinds and polishes the workpiece by sandwiching it between upper and lower rotating grinding wheels, allowing us to accommodate various materials, including non-magnetic and difficult-to-machine materials. Please feel free to consult us when needed. 【Product Specifications】 ■ Material: SKH51 (Molybdenum-based high-speed tool steel) ■ Processing Type: Grinding ■ Dimensions & Precision: φ15, Thickness: ±5um or less ■ Industry: Automotive ■ Corresponding Lot Size: 50,000 pcs/month *For more details, please refer to the related links or feel free to contact us.
