Round parts, machining, drive device components, high-precision processing, prototype, mass production.

Supporting Japan's transportation infrastructure with cutting-edge technology.

High-precision and high-strength "round parts (cylindrical parts)" are widely used in drive systems for industrial machinery and railway vehicles. Shafts, bushes, gear components, sleeves, couplings, etc.—all of these are parts that play important roles in rotation, transmission, and support. Our company specializes in the cutting processing of these "round parts" due to our many years of machining experience. ■ Our Strengths: High Precision × Prototype and Mass Production Support 〇 High-Precision Lathe Processing Micron-level dimensional control using NC lathes and composite lathes Support for geometric tolerances such as perpendicularity, coaxiality, and cylindricity Simultaneous processing of inner and outer diameters and keyway machining is also possible Finishing processing after quenching and heat treatment is also supported.

Product Example: Connecting Production

Product Example: Connecting Production

Initial production of products using a trial mold! Production is possible for several tens of thousands of shots due to the trial steel mold.

We would like to introduce a case of interim production conducted for an automotive parts manufacturer. The company faced challenges such as taking too much time for mass production tooling, which made the mass production schedule tight, and wanting to transition directly from prototype to mass production. They were able to start mass production immediately after the prototype and conduct interim production using the prototype model until the mass production tooling was ready. 【Case Overview】 ■Challenges - Too much time taken for mass production tooling, leading to a tight mass production schedule - Desire to transition directly from prototype to mass production ■Results - Mass production started immediately after the prototype - Initial mass production items produced using the prototype mold *For more details, please refer to the related links or feel free to contact us.

Proposal for Prototype to Mass Production

Proposal for Prototype to Mass Production

Even with a prototype mold, we implement mold design with mass production in mind! It is possible to start mass production in a short lead time.

The production of prototypes requires a balance of "delivery time," "precision," "cost," and "quality." Our company will propose suitable methods and processes while considering each of these balances for our customers. Additionally, please feel free to consult us not only about the press parts we prototype but also about mass production of products prototyped by other companies. When it comes to mass production, we also consider the total cost reduction of press products and will propose design changes as needed. 【Mitaka Industry's Prototype Balance】 ■ Precision: Achieving press-processed products with a precision of 1/100mm from the prototype stage ■ Cost: Addressing prototype needs while considering the overall cost from prototype to mass production ■ Delivery Time: Responding with an in-house integrated system, accommodating short delivery times starting from one week ■ Quality: Ensuring compliance with customer drawing precision requirements through reliable technology and high-performance measuring equipment *For more details, please refer to the PDF materials or feel free to contact us.
