Machining technology

Ultra-small burr-less technology

Nishida Precision can perform burr-less machining of minute components, leaving almost no burrs on each edge.
The burr height after machining is kept to no more than 5 µm.

Product information
  • ■Outer diameter (maximum)：φ0.3mm　+/-0.01
  • ■Total length：0.5mm　+/-0.01
  • ■Work material：SUS303
Drilling technology

Nishida Precision can drill a hole with an ultra-small diameter of φ 0.15 mm.
We can also conduct small-diameter deep hole processing with hole depth (L)/hole diameter (D) ≥ 25.

Product information
  • ■Outer diameter (maximum)：φ0.4mm　+/-0.01
  • ■Hole diameter：φ0.15mm　+/-0.01
  • ■Hole depth：4mm（Penetration）　+/-0.0
Undercut machining technology

End face grooves inside inner diameter grooves can be machined by undercutting.
Using tools manufactured in-house, we handle the shapes that cannot be achieved with commercially available tools, so we can deliver a prototype component within a short period of time.

Product information
  • ■Hole diameter：φ8mm
  • ■Wall grooves：1mm×6mm
  • ■Work material：SUS303
Thin wall machining technology

Thin walls with 0.04 mm ± 0.01 per side can be machined.

Product information
  • ■Thickness：0.04mm　+/-0.01mm
  • ■Outer diameter：φ16.8mm, Inner diameter：φ16.72mm
  • ■Height：20mm

Cutting tool manufacture

Nishida Precision manufactures its own cutting tools for shapes that cannot be achieved with commercially available cutting tools. Therefore, we can handle complex shapes and deliver a prototype component within a short period of time.
Also, we have improved the quality level by in-house manufacturing a cutting tool that is suitable for each product. We currently manufacture around 2,000 types of cutting tool, and among them, approximately 300 are original cutting tools made in-house. Nishida Precision has been manufacturing cutting tools since our company was founded, and it can be said that our high-precision machining originates in the manufacturing of cutting tools.
Since even the slightest difference in the cutting edge angle is directly linked to machining quality and improvements in product accuracy, skilled craftsmanship is required for manufacturing cutting tools. Nishida Precision’s strengths include our creative ability to devise cutting tools for higher precision machining, to say nothing of our cutting tool polishing technology that has been passed on since the foundation.

Optimization of setup (manufacturing conditions)

Adjustment and management of cutting conditions

In order to optimize machining equipment cutting conditions, such as the spindle speed and cutting tool mounting angle, we perform trial machining using setup samples.
We measure sample dimensions, and visualize machining with control charts (X-bar, R control charts, etc.) to determine optimal conditions.
