三田工機 Product Lineup

We would like to introduce the "Diamond Compax V Block" handled by Sanda Koki Co., Ltd. It is used as a measuring platform by setting two V blocks with a specified gap and placing a precision pin in the V section. In the case of this product, the key point is that even when placing the precision pin with a gap of 100±0.03mm between the two V blocks, the pin misalignment is less than 3 microns. [Points during processing] - Even when placing the precision pin with a gap of 100±0.03mm between the two V blocks, the pin misalignment is less than 3 microns. - It is important to finish the steel and diamond parts with high precision. - Customization is also possible depending on the customer's usage conditions. *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce the "Diamond Compax V Support" handled by Sanda Koki Co., Ltd. It is used for placing products during processing and measurement. It is extremely hard, so it does not wear down, and it has a precision polished finish, ensuring parallelism is determined in microns. [Points for Processing] - Can be used with high precision just by placing it - Customization is possible depending on the customer's usage situation *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce the "Diamond Compax Step Blade" handled by Sanda Koki Co., Ltd. Due to its high wear resistance, it can be used for a long time once the setup is changed. Achieving high precision processing of 1 micron is difficult even with hardened steel polishing, but our product stands out by realizing high precision with the even more challenging diamond. 【Points during processing】 - It is possible to process without damaging the workpiece. - Mass production of high-precision multi-step pins is also possible. - Once the setup is changed, it can be used for a long time. - High precision is achieved with the challenging diamond. - Compatible with both through and stop blades. - Customization is possible according to the customer's usage conditions, such as shape and dimensional tolerances. *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce the "Diamond Compact Attached Stop Block" handled by Sanda Koki Co., Ltd. This component is used at the tip to press products against the diamond part with stable dimensions. By using a diamond compact, we achieve stable dimensions and flatness. Please feel free to contact us when you need assistance. 【Points during processing】 ■ High-precision flat grinding with dimensional tolerances from the steel surface in microns and flatness also in microns. ■ Customization is possible depending on the customer's usage conditions, such as shape and dimensional tolerances. *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce the "Diamond Compax Center" handled by Sanda Koki Co., Ltd. It is well-suited for small lot processing due to its excellent slip resistance, but especially effective for mass production processing because of its outstanding wear resistance. We guarantee the roundness of the diamond part in contact with the workpiece with measurement data, allowing for high-precision processing from small lots to mass production with peace of mind. 【Points during processing】 ■ Precision grinding finish on the tip diamond part and taper part ■ Measurement data attached for the runout and coaxiality of the taper part (reference surface) and tip part, as well as the roundness of the tip part using a roundness measuring machine ■ After-sales support including regrinding and repair of the tip part *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce the "Diamond Compax Internal Diameter Measuring Tool" handled by Sanda Koki Co., Ltd. This product has the advantage of non-contact measurement, which prevents damage to critical areas of the workpiece. Since it uses diamond, it experiences very little wear, allowing for stable measurements over a long period. [Points during processing] ■ It is challenging and requires skill to precisely grind the diamond only on the necessary parts of the hardened steel, ensuring that there is no step between the steel and diamond sections. *For more details, please refer to the PDF document or feel free to contact us.

Our company performs precision processing using diamond compacts that combine high hardness, wear resistance, low friction coefficient, and impact resistance. To manufacture products tailored to customer drawings and requirements, we select types and sizes (there are limitations on the size of sintered bodies) and bond them with other metals (base materials). We use "brazing" or "adhesive bonding" depending on the application of the product. During the polishing process after bonding, we pay attention to diamond chipping (such as chipping and cracking) and finish with high precision in microns (1/1000 mm). With our many years of experience, we strive daily to ensure stable and high-precision manufacturing by selecting the types of diamond materials and the diamond grinding wheels to be processed. 【Examples of Processed Products】 ■ Inner diameter measuring probes with diamond compacts ■ Centers with diamond compacts ■ V-blocks with diamond compacts ■ Stops with diamond compacts ■ Step blades with diamond compacts *For more details, please refer to the PDF document or feel free to contact us.
