村上製作所 List of Products and Services

Our company has made it possible for even those with less experience to achieve high-precision large special screw machining, which could only be accomplished by skilled workers using general-purpose lathes until now, allowing for stable supply. Moreover, with NC-controlled automatic machining, it can now be performed safely. Additionally, since both male and female threads can be machined in the same shape, we expect an increase in durability compared to conventional products. Please feel free to contact us if you have any requests. 【Available Precision】 ■ Adjacent pitch error: within 0.03mm ■ Single pitch error: within 0.04mm ■ Cumulative pitch error: within 0.07mm/10 pitches ■ Male and female thread fitting adjustment: over 70% *For more details, please download the PDF or feel free to contact us.
