CNC milling capability, multi-face machining in a single setup - Seiko Industry Vietnam

In precision mechanical machining, block-shaped, box-shaped, large plate parts, jigs/fixtures, or components for semiconductor manufacturing equipment often require more than just the correct dimensions for each individual surface. More importantly, it's the ability to control the **inter-surface relational accuracy**, hole positions, flatness, perpendicularity, parallelism, and surface quality after machining. For these parts, each time the workpiece is removed and re-fixtured, errors can arise. Therefore, **multi-face machining in a single setup** is a crucial capability that helps reduce fixturing errors, limit cumulative errors, and increase stability in repetitive production. Seiko Industry Vietnam possesses capabilities in **CNC milling**, **CNC milling machines**, **horizontal milling machines**, vertical milling machines, 5-axis machines, EDM machines, grinding machines, and inspection systems to meet the demands for high-precision aluminum/stainless steel parts with stringent aesthetic requirements and production according to drawings.

What is CNC Milling? Why is it important in precision mechanical machining?

CNC milling is a cutting process that uses a **CNC milling machine** controlled by a numerical program to shape parts according to drawings. This method can machine flat surfaces, grooves, pockets, holes, steps, profiles, and assembly surfaces. In precision mechanical machining, CNC milling helps control dimensions, hole positions, flatness, perpendicularity, and consistency between products. For multi-face parts, CNC milling capability needs to be combined with suitable machinery, precise fixtures, optimized machining programs, and post-machining inspection processes. Especially when products have multiple assembly faces or interrelated hole positions, **multi-face machining in a single setup** helps reduce the risk of deviations caused by repeated workpiece removal, re-fixturing, and re-alignment.

Seiko Industry Vietnam's CNC Milling - Multi-Face Machining in a Single Setup Capability

Seiko Industry Vietnam is a factory in Vietnam belonging to Akita Seiko Co., Ltd., located in Thang Long II Industrial Park, Hung Yen province. The company operates in the field of **precision mechanical machining**, with its main products being components for semiconductor manufacturing equipment. Main materials include aluminum **A5052, A5056, A6063, A7075** and stainless steel **SUS303, SUS304, SUS316**.

Diverse and Modern Machine System

To meet the demands for complex products requiring precise CNC milling and multi-face machining, Seiko Industry Vietnam possesses a diverse range of machining equipment, including:

Additionally, the factory also has grinding machines, drilling machines, Hairline finishing machines, washing machines, packaging machines, and other auxiliary equipment to support the post-machining product finishing process.

To perform multi-face machining in a single setup, a CNC milling machine alone is not enough. The factory needs to combine suitable machines, precise fixtures, optimized machining programs, operational experience, and post-machining inspection capabilities. These are the combined capabilities that enable Seiko Industry Vietnam to meet the demands for precise parts for manufacturing equipment, jigs/fixtures, and high-requirement aluminum/stainless steel components.

Capability for Machining Large-sized Parts and Plate-shaped Parts

Seiko Industry Vietnam has the capability to machine workpieces up to 2,000 x 1,000 x 750 mm, suitable for large plate parts, blocks, frames, machine bases, industrial jigs/fixtures, and components with large length/width dimensions. For large-sized parts, the challenge is not just whether the machine can process them. What's important is controlling flatness, parallelism, perpendicularity, hole positions, consistency between surfaces, and the aesthetic appearance after machining. Thanks to the combination of vertical milling machines, **horizontal milling machines**, 5-axis machines, EDM machines, grinding machines, and inspection equipment, Seiko Industry Vietnam can support large plate-shaped products, aluminum/stainless steel blocks, industrial jigs/fixtures, or parts requiring multi-face machining according to drawing specifications. For these products, Seiko not only machines according to drawing dimensions but also focuses on controlling the consistency between machined faces, hole positions, and surface quality after finishing.

Closed Production Process from Material to Packaging

Seiko Industry Vietnam has the capability to control a closed production process from raw material input to finished product. The process may include:

For aluminum/stainless steel components for semiconductor manufacturing equipment, risks are not limited to dimensional errors but also include scratches, burrs, color variations, impacts during internal transportation, or aesthetic defects after surface treatment. The ability to control a closed process helps Seiko Industry Vietnam reduce the risk of errors occurring between stages, especially for products requiring stable surfaces, no scratches, no color variations, and meeting the aesthetic inspection standards of Japanese customers.

Post-CNC Milling Quality Inspection Capability

Multi-face machining in a single setup must be accompanied by inspection capabilities to confirm post-machining accuracy. For multi-face parts, quality cannot be assessed solely by the dimensions of individual surfaces. What's important is to check the interrelationship between faces, holes, and assembly surfaces. Seiko Industry Vietnam has an inspection equipment system including:

• Automatic and semi-automatic 3D measuring machines.
• Image measuring machines.
• Microscopes.
• Roughness measuring equipment.
• Film thickness measuring equipment.
• Micrometers, calipers, dial indicators, thread gauges, plug gauges, pin gauges, ring gauges, and many other measuring tools.

Seiko Industry Vietnam's 3D measuring machines have a measurement range of 900 x 1500 x 600 mm, supporting the inspection of relatively large-sized parts. After CNC milling, Seiko can inspect factors such as overall dimensions, hole positions, flatness, perpendicularity, parallelism, concentricity, assembly surfaces, and aesthetic appearance after machining. This is a crucial foundation to ensure products meet actual assembly requirements and maintain consistency across production batches.

Applications of CNC Milling and Multi-Face Machining Capabilities

Seiko Industry Vietnam's CNC milling and multi-face machining in a single setup capabilities are suitable for product groups such as:

• Components for semiconductor manufacturing equipment.
• Jigs, fixtures, inspection gauges.
• Housings.
• Gearboxes.
• Valve bodies.
• Pump casings.
• Large plates, aluminum/stainless steel blocks, frames, and machine bases.
• High-precision and aesthetically demanding aluminum/stainless steel components.

These are product groups that often have multiple machined faces, multiple holes, multiple assembly surfaces, or require relational accuracy between positions. When machined using a suitable CNC milling system and with reduced fixturing changes, products can be better controlled in terms of errors, surface quality, and stability in repetitive production.
