In addition, this gives very high thermal stability for the machine structure. Machine has got the component swiveling kinematics, which enables the grinding of grooves in a single axis movement. As a process, this is more accurate when compared with wheel swiveling kinematics wherein the groove is ground by interpolating two CNC axes.
Complementing these technologies is T1's unique kinematic structure. Its 155-degree tilting A-axis and deep chest column provide full five-sided machining capability for parts up to 1,500 mm in diameter. The key to the T1's flexibility is its 12,000-rpm spindle. The T1 tackles titanium with 1,000 Nm of duty-rated torque from spindle start ...
