Track Record in Machining
- By leveraging our extensive network of local manufacturing partners, we can handle a wide range of machining processes, including cutting, cold heading, and surface treatments such as plating.
- As a trading company, we utilize our strengths to select the most suitable manufacturing
equipment and processing methods based on the intended application. - For urgent requests, we provide quotation within 24 hours and offer standard manufacturing lead times ranging from one to ten days.
Our company also handles cut-machined products manufactured using NC lathes and machining centers, with a level of experience comparable to our track record in header- processed products.
Even for identical products, the required precision may differ depending on the application.
To meet the specific needs of each user, we carefully select the most suitable machinery and
provide detailed technical support in accordance with customer requirements.
We offer Optimal Precision and Pricing for Your Application
| Overview | Overall length: 18 mm / Double-ended screw: M3 / Milled head / Material: Brass (Ni plated) The head (“–” type) is a spacer used for semiconductor substrate assembly. |
Although the product dimensions are the same, the production lot was divided into two categories based on required precision.
・Lots requiring ultra-fine dimensional accuracy depending on the customer’s equipment
・Lots requiring cost-effective production within standard tolerances in accordance with JIS B 0405
To meet these needs, we selected the machining equipment accordingly and provided the requested precision and pricing for both types of lots.
| Precision | Machine | Quantity | |
| High (Tolerance 0.01) | NC Lathe | 500 | |
| Standard (Tolerance ±0.2) | Cam-type Automatic Lathe | 500 |
We Delivered a Product Requiring Multiple Processing Steps Through Our Local Network
| Overview | Overall length: 36 mm / Screw section: M6 / Body polished / Material: Steel (Both ends PK) |
This is a special-size screw used in industrial machinery.
After forming on a NC lathe, the screw undergoes heat treatment, PK processing, body polishing, with four different factories involved in the process.
This is a case that showcases the collaborative strength unique to the Higashi-Osaka and Yao regions, where specialized functions are concentrated.
