Features
High-rigidity structure that supports powerful machining MHT series
- (1)Column
It adopts a center head type box column that achieves high rigidity and thermal stability. Deformation due to cutting force during processing is minimized thanks to a thermo-symmetric structure in which the spindle is centrally located, therefore that machining accuracy is stabilized. - (2)Table
The table thickness has been increased by 30% compared to the conventional model. Boasting high rigidity, it ensures safety and high productivity even when loading large workpieces or performing heavy duty cutting. - (3)Bed
It adopts a T-shaped structure that strongly fastens the table bed and column bed to achieve the machine's accuracy in longer period.
The MAF-EII series are designed to machine larger size workpieces with higher accuracy.
The best-in-class spindle performance
It supports various types of workpiece machining such as high-speed machining with a small-diameter drill, low-speed high-output machining with a large-diameter milling tool, and high-torque machining with large-diameter boring.
The extension of the boring spindle is 800 mm, the best in its class
Good accessibility to workpieces, ideal for deep hole boring
Quick axis movement can shorten non-cutting time
Rapid traverse rate: X, Y, Z-axis: 15 m/min, W-axis: 10 m/min, B-axis: 500 deg./min
