Bronze or Brass bars CNC OEM parts

Use of the combined CNC machine reduces the number of processes and allows complicated cutting work

A single process using the combined CNC machine turns a workpiece relatively large in diameter into a processed or finished product, which advances the delivery date and reduces costs.

Use of the NC lathe and machining center

The use of various equipment and the machining center improves productivity while maintaining processing accuracy.

This allows a smooth transition from trial production through commercialization to mass production.

Details of processed product
The lateral hole is a complicated oval in shape.
2 holes on the edge face are eccentric:
  • one is for a bottom attached M3 screw
  • the other is the pierced step hole

Equipment features
  • Equipped with a Y-axis in addition to the C-axis.
  • The bar type can process a product as large as φ51 mm.
  • The chucker type can process a product up to φ250 mm.
Products can be fully processed within only a single process using the combined CNC lathe with 2 spindles and 2 saddles (bar type) equipped with the Y-axis.
This example chooses process division as it achieves more efficient processing in this particular case.
