Technology

Grinding process

One of our strongest points. We can solve any problems with your grinding process using our cultivated technologies.

Cylindrical grinding

Technological specialty: taper processing, centerless processing, high-precision processing (+/-1 μm), cam processing
Work size: φ1 to φ300 mm, Length = 500mm or less

Internal grinding

Technological specialty: Small-diameter deep-hole grinding (φ1 mm or more), taper processing, high-precision processing (+/-1.5 μm)
Chucks are all in-house products.
Work size: φ1 to φ200 mm, 7D or less

Surface grinding

Technological specialty: mirror finishing, profile grinding process
Work size: up to 600 × 400 mm

Cutting process

We have many machining centers that support high-speed and high-precision processing. We also have 5-axis machining centers with additional 2 axes, which demonstrate their specialty for processing robot parts with strict geometric tolerances and prototype parts for the full cutting of pure materials.

Machining

Technological specialty: aluminum high-speed processing, small-diameter deep hole processing (φ2 × 200 mm), grinding processing
Work size: up to 300 × 300 × 300 mm in block, or 600 × 400 mm in plate

Lathe turning

Work size: up to φ200 × 400 mm

Electrical-discharge
machining(EDM)

Using our original ideas, successful application of wire-cut and die-sinker electrical-discharge machining (EDM) on the machining of parts has been achieved. More difficult shapes, precision, and machining on difficult-to-cut materials can be obtained by using our EDM, instead of other traditional machining process.

Wire-cut EDM

Technological specialty: slotted hole drilling (symmetry: 5 μm), slit processing (wire diameter: 30 μm or more)
Work size: up to 300 × 300 × 300 mm in block

Die-sinker EDM

Technological specialty: fine hole drilling (φ20 μm or more)

Assembly

Precision-machined parts are completed only when assembled. We provide total support including precision assurances, leak tests, and operation checks after assembly. Especially, we specialize in bonding, press-fitting/light press-fitting, and shot blasting (aero lapping etc.).

Measurement

Even if the workpieces can be machined, unless the workpieces is measured correctly, they will lose half of their value. We are fully equipped with various precision measuring instruments, including internationally-valued Zeiss’ 3D measuring machines. Measurement data proves our machining capability that satisfies our customers.

In-house Manufacturing of Tools

Machining of the parts with a high degree of difficulty requires special tools and thus results in a long lead time. To avoid such situation, we have various equipment for in-house manufacturing of the tools with special shapes, which realize difficult processing and quick delivery.
