BC3116

High-rigidity and high-precision mechanical structure

  • Main mechanical structures, such as: base, column, beam, saddle and headstock, etc., are made of Meehanite casting iron with the process of heat treatment to release the residual stress to ensure every actual miniature movement and to maintain a long-lasting accuracy.
  • Box-shaped structural design on beam, together with ladder-like layout of linear guideway makes the combining span of saddle wider and assures a powerful and stable machining capability on the spindle.
  • The design with 3-axis roller-type high-precision linear guide-ways, of high rigidity and low friction, acquires a quick response in acceleration and deceleration.
  • Gear-driven X-axis assures the optimal performance in transmission with heavy loading.
  • The counterweight design of dual hydraulic cylinders on spindle, together with the auxiliary Nitrogen counterweight makes it working smoothly with optimal dynamic accuracy.

High-precision and high-performance on headstock

  • In accordance with different machining demands, spindles on BC series can choose either gear-drive or direct-drive, ranging from 6Krpm to 10Krpm.
  • Gears within the gear box on headstock are of the highest quality render the highest transmission efficiency.
  • The complete cooling system for spindle and gear makes spindle well-lubricated, effectively refrains from thermal growth and decreases thermal deformation.
