東進工業 List of Products and Services

With over 50 advanced machines, including state-of-the-art NC lathes and machining centers, as well as multi-tasking NC lathes, we excel in NC lathe processing, machining, and mechanical processing for both small and large products. We actively introduce labor-saving equipment such as loaders to enhance productivity and achieve speedy responses. Naturally, as productivity improves, low-cost production becomes possible. For mass production of various parts through machining, you can count on us! For more details, please contact us or refer to our catalog.

Our company has established a consistent production system that handles various shapes of castings (FC/FCD), die-casting, gravity casting, and other materials received from casting manufacturers, using new machine tools for the processes following casting. In response to the requests of major client manufacturers, we are able to provide finished products to large manufacturers. Additionally, before customer shipments, each manufacturing representative can hold meetings promptly, allowing for immediate understanding and correction of the workflow, issues, and areas for improvement, which contributes to quality enhancement. 【Features】 ■ Establishment of a consistent production system for processes following casting ■ Ability to provide finished products to large manufacturers ■ Each manufacturing representative can hold meetings promptly before customer shipments ■ Immediate understanding and correction of workflow, issues, and areas for improvement ■ Contributes to quality enhancement *For more details, please refer to the PDF materials or feel free to contact us.

This is a machining example using a horizontal machining center (table size 630 square). The processed part is a torque converter case mounted on a medium-sized forklift weighing 3.5 to 5 tons, which requires strict geometric tolerances (position, coaxiality, perpendicularity) and precision in the micron range. The industry that introduced this is the industrial machinery forklift industry. 【Machining Example】 ■ Material: FCD (ductile cast iron) ■ Dimensions: 600×550×300 (height × width × depth) ■ Shipping destination: Okanezu Industry (Powertrain ASSY) ⇒ Mitsubishi Logisnext Co., Ltd. ■ Machining machine: Horizontal machining center (table size 630 square) We also accept bush pressing and deep hole machining. *For more details, please refer to the PDF document or feel free to contact us.

The processed parts are hydraulic components for construction machinery, requiring strict tolerances for surface roughness and geometric tolerances (such as coaxiality and cylindricity) with high precision. In addition to machining, some parts may also require honing during hole processing depending on the requirements. 【Processing Example】 ■Material: FCD (ductile cast iron) ■Dimensions: 150mm in length ■Shipping Destination: Caterpillar ■Machining Equipment: Vertical Machining Center We also accept bush pressing and deep hole processing. *For more details, please refer to the PDF document or feel free to contact us.

This is a machining example using a horizontal machining center (table size 500 square). The processed part is a transmission case mounted on a forklift, requiring strict geometric tolerances (position, coaxiality, perpendicularity) and surface roughness, with precision demanded in microns. The industry introducing this is the industrial machinery forklift sector. 【Machining Example】 ■ Material: ADC (Aluminum Die Casting) ■ Dimensions: 400×350×200 (Height × Width × Depth) ■ Shipping Destination: Okanezu Industries (Powertrain Component Assembly) ⇒ Mitsubishi Logisnext Co., Ltd. ■ Machining Equipment: Horizontal Machining Center (Table Size 500 Square) We also accept bush pressing and deep hole machining. *For more details, please refer to the PDF document or feel free to contact us.

We mainly perform processing for trial production and large order lots (lot size: 100 to 1,000 units). Even for complex-shaped workpieces, such as castings, which are often avoided by other companies, we can provide high-quality and speedy responses using in-house designed dedicated jigs and special tools. 【Features】 - Workpiece size: approximately 650mm square (300mm to 700mm) - Long-standing experience in handling complex-shaped workpieces, such as castings, which are often avoided by other companies - Achieving production efficiency and cost reduction through a well-equipped number of facilities - In-house design and production of jigs and special tools *You can view the processing image collection via PDF download. Please feel free to contact us for any other inquiries.

This is a machining example using a horizontal machining center (table size 630mm square). The processed items are a swing bracket and a link bucket, which are mounted on hydraulic excavators. Our company was able to handle everything from cutting processing to bush pressing into holes. The industry we serve is the construction machinery sector. 【Processing Example】 ■Material: FCD (ductile cast iron) ■Size (mm): 700×550×600 (height×width×depth) ■Shipping destination: Akioka Co., Ltd. (casting processing) 　　　　　⇒ Our company (cutting processing & bush pressing) ⇒ Major construction machinery manufacturers ■Machining equipment: Horizontal machining center (table size 630mm square) We also accept bush pressing and deep hole processing. *For more details, please refer to the PDF document or feel free to contact us.
