Machining technology
● Minute burr-less machining technology
Nishida Precision can perform burr-less machining of minute parts, with almost no burrs left on each edge.
Post-machining burr height is kept to no more than 5 µm.
Product information
■Thickness (max. point): φ0.3 mm +/-0.01
■Length: 0.5 mm +/-0.01
■Work material：SUS303
● Drilling technology
Nishida Precision can drill holes with ultra-small diameter of φ0.15 mm.
We can also handle small-diameter deep hole drilling with hole depth (L)/hole diameter (D) ≧ 25.
Product information
■Outer diameter: φ0.4 mm ±0.01
■Hole diameter: φ0.15 mm ±0.01
■Hole depth: 4 mm (through) ±0.01
● Undercut machining technology
End face grooves inside inner diameter grooves can be machined by undercutting.
Shapes that cannot be machined with commercially available tools can be handled with Nishida Precision’s in-house manufactured tools, allowing short deadlines for prototypes to be met.
Product information

■Wall grooves: 1 x 6 mm
■Work material：SUS303
● Thin wall machining technology
Thin walls with 0.04 mm ±0.01 per side can be machined.
Product information
■Thickness: 0.04 mm ±0.01 mm
■Outer diameter: φ16.8 mm, inner diameter: φ16.72 mm
■Height: 20 mm
Cutting tool manufacture
Nishida Precision manufactures its own cutting tools for shapes that cannot be machined with commercially available cutting tools. This allows us to machine complex shapes and meet short deadlines for prototypes. This allows us to machine complex shapes and meet short deadlines for prototypes. We currently carry around 3,000 types of cutting tool, of which approximately 800 are made in-house. Nishida Precision has been manufacturing cutting tools since our company’s founding, and this can be said to be the origin of our high-precision machining. Since even the slightest difference in the cutting edge angle is directly linked to machining quality and improvements in product accuracy, cutting tools require skilled craftsmanship. In addition to cutting tool polishing technology passed on through the years since our founding, another of Nishida Precision’s strengths is our creative ability to come up with cutting tools for higher precision machining.
Setup (manufacturing conditions) optimization
Adjustment and management of cutting conditions
In order to optimize machining equipment cutting conditions, such as spindle speed and cutting tool mounting angle, Nishida Precision performs 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.
Analysis with 3D image analysis
Nishida Precision uses image measuring instruments to convert part shapes into three-dimensional images for the numerical analysis of shapes and surface conditions.
