Presentation of Processing Case Studies: Grinding processing capable of handling various materials, including difficult-to-machine materials.
Unique double-sided lap polishing technology! Double-sided polishing and lap polishing that does not depend on the material of the workpiece.
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.

Company information
Suwa Machinery Works was founded in 1953 and has been engaged in the manufacturing of precision parts and machine tools. In 1960, we established the Toyokawa Factory in Toyokawa City, Aichi Prefecture, and have continued to this day. Since our inception, we have been involved in the processing and assembly of optical equipment, contributing to the development of local industries through reliable products. As optical technology expands into the field of "light" technology, our long-cultivated precision machining skills are enhancing our constant temperature facilities to meet the demand for micron-level precision, enabling even higher levels of accuracy. Furthermore, in addition to high-precision machining, we have established the capability to handle a wide variety of small quantities and complex processing techniques, laying the foundation for producing high value-added, high-quality products, thereby earning the trust of customers in various fields. Suwa Machinery Works is now moving forward vigorously in an era that suggests new possibilities, contributing to the field of precision parts.
