It is possible to suppress dimensional variation within the lot! Compatible with screw sizes φ0.6 to 4.0.
In our lead screw grinding, we perform screw grinding processing using dedicated machines developed for stable quality, high precision, and high efficiency for mass production. Processing is possible after hardening, allowing for hardness of Hv600 or higher and bending of 0.02mm or less. The clearance can be controlled for sets with nuts. Additionally, we consistently produce some of the world's smallest class nuts and screws in-house. 【Features】 ■ Uses large grinding wheels for processing tools, offering excellent tool durability ■ Capable of reducing dimensional variation within lots ■ Achieves good and stable surface roughness on the flank compared to cutting and rolling ■ Can process various materials including soft, hard, and hardened materials ■ Capable of processing hollow materials that are difficult to process with rolling or cutting ■ Allows for processing with minimized bending even for small diameter products *For more details, please refer to the PDF document or feel free to contact us.
