Yamada Seisakusho Co., Ltd. 

We offer one of the highest-quality hydraulic components in the field of agricultural and industrial machinery. 

The field of precision parts machining always requires high precision, and most manufacturers mainly use machining technology. However, precision grinding technology is highly evaluated because grinding can achieve higher precision than machining. Our company excels at manufacturing poppet valves, which are hydraulic components, and we conduct all the manufacturing processes other than thermal processing in-house. Our grinding method is called whetstone fabrication. This involves processing the component using an NC lathe, and then processing its jagged part once more using an NC cylindrical grinder. Tolerances in outside diameter, roundness, and concentricity are within 2.0 microns, which remain the same in mass production.

Manufacturing technology for hydraulic components such as poppets and plungers

592843facbc809ca129afed33b96fae3.png

[Product description] Our company particularly excels at manufacturing hydraulic equipment components such as poppets and valve seats, and we conduct all manufacturing processes except thermal treatment in-house. Components are machined with NC lathes, and the ragged parts are then ground once with an NC cylindrical grinder (whetstone processing). The outer diameter dimensions, roundness, and concentricity are controlled to less than 2 microns, and the same precision applies to mass production. [Market share/Ranking] More than 70% of a major agricultural machinery manufacturer’s products are equipped with our poppets (hydraulic component). [Major facilities and equipment] NC cylindrical grinders (13 units); NC internal grinders (4 units); centerless grinders (3 units); NC double head grinder (1 unit); rotary grinder (1 unit); NC lathes (5 units); various measuring instruments.

Sekishin Inc.
We conduct metal processing for high-precision parts. We have a track record of deliveries to areas in which high precision and high quality are required. This includes communications satellites, aerospace and aircraft, medical treatment, and nuclear power. We excel at processing complicated shapes, and have also received many orders for prototype processing. We have installed abundant equipment, including 15 sets of 5-axis control machining centers.
Kentec Co., Ltd.
We have established totally innovative sealing technology, and developed a washing system without solvent loss. We are carrying on design, manufacturing and sales of completely-sealed solvent equipment for industries which utilize solvent for washing and coating. Since the solvent treatment is performed inside sealed equipment, there is no discharge of solvent. Therefore, no environmental pollution occurs. Since inflow of air into the equipment and the outflow of inner gas do not occur, we can perform treatment at a temperature higher than the flash point of the solvent in a stable, incombustible atmosphere. We received the “Award for Excellent New Technology and New Product of Small and Medium Enterprises” sponsored by Asahi Bank SME Promotion Foundation & Nikkan Kogyo Shimbun.
Daishin Co., Ltd.
We were founded in 1976 as a machinery manufacturer, and have focused on technological innovation with the changes of the times. We have a strong challenging and pioneering spirit.
