Has this ever happened to you?
I want to make a prototype, but I'm looking for a company that can take orders in small batches, even just one unit.
An old machine part that I don't have a blueprint for has broken down, and I'm looking for a company that can make it.
The tools and jigs we're using wear out quickly. Is it possible to make something that lasts longer?
Since quality is crucial, we are looking for a company that can manufacture and guarantee precision down to the micron level.

Mita Koki Co., Ltd.'s commitment
1. We handle all processes in-house, from cutting to grinding.
High accuracy guaranteed
After integrated production, we measure the accuracy using our in-house measuring equipment and thoroughly guarantee the product's accuracy with data from inspection reports.
Furthermore, products bearing the Mita Koki mark come with a guarantee that includes repairs and replacements in the unlikely event of any issues.
Our strengths lie in our ability to offer consistently high-quality products, even for single-unit purchases, and our comprehensive after-sales service. We also offer tool regrinding and center regrinding services, so please feel free to contact us.
2. Micron-level precision machining!
Capable of handling a wide variety of products in small batches.
We have been doing business with a major automotive precision parts manufacturer since our founding, supplying our products such as tools and jigs to their precision parts manufacturing lines. Our track record of high quality and stable delivery has been highly valued, allowing us to expand our product range. We handle a wide variety of materials, including various types of steel, cemented carbide, and diamond compax. We can process orders from a single piece, regardless of material or type.
3. Implement value analysis/value engineering proposals that pursue the best solution for the customer.
We strive to achieve the best possible outcome for our customers and offer value analysis (VA) and value engineering (VE) proposals. From improving wear resistance by using carbide or diamond alloys on machine parts to enhancing the safety of hand tools, we offer improvement suggestions for every aspect. If you believe improvements are needed, please contact us, and we will provide suggestions from our perspective.
Sample results (past performance)
This center features a highly wear-resistant tip with a diamond-compax design. It comes with a precision inspection report, demonstrating a roundness of 0.5 microns or less and a runout accuracy of 1-2 microns or less, ensuring reliable use. It's the ideal center for high-precision parts machining.
This stepped blade features high wear resistance thanks to the use of diamond compax. The tolerance of each step is a precise ±0.001, allowing for reliable machining of precision shafts in mass production. The diamond surface provides excellent lubrication, enabling clean and even polishing of the workpiece.
These are precision machine parts. High-precision parts are essential for the precision components attached to your machinery and for custom-designed jigs. Even without drawings, we can manufacture parts according to your specifications based on physical samples, etc. Precision can be achieved on the micron order.
