Processing example of small and multiple pores

Processing example of small and multiple pores

We are good at processing components with small and multiple pores for semiconductor and FPD (liquid crystal and organic EL) manufacturing equipment using state-of-the-art machining centers and NC lathes.

Features

Machining Centers

  1. The maximum size of workpiece that can be machined is 1,500mm x 1,500mm.
  2. The convex high-precision processing of 25 μm +/- 5 μ (dozens of places) within the range of φ 330mm is possible.
  3. We have an experience of machining pure aluminum, A5052, A6061, pure nickel, SUS316, SUS304, and copper in the past.

Lathes

  1. The maximum diameter and length of workpiece that can be machined are φ880mm and 890mm, respectively.
  2. Large-bore components as well as thin plates can be machined precisely to have high degree of flatness and parallelism.
  3. We have an experience of machining pure aluminum, A5052, A6061, pure nickel, SUS316, SUS304, and copper in the past.

Processing Technologies

Small and multiple cores: We have an experience in mass-producing porous plates with pores of 0.55 mm in diameter and 20 mm in depth.
Countermeasure against built-up edge: We use center-through drills that can deal with the bores of 0.8 mm or larger in diameter.
No burr machining: We machine components in a way such that the generation of burrs is reduced to as few as possible and we perform post-processing to eliminate tiny burrs.
Precision Cleaning
Precise flatness and parallelism: We use workpiece holding methods suitable for respective product shapes and we perform intermediate heat treatment in house to realize high-precision processing.
Pore inspection: The data of all pores inspected using a contactless image measuring device can be saved.
Heat treatment: The degassing as well as stress-relief heat treatments of stainless steel can be performed in house.
Since heat treatment is performed using vacuum furnaces, it is not required to eliminate oxidized films.
