Features:
- BTMC 12 series is upgrade product specialized for large type VMC machine 1270/ 1370/ 1690/ 1890
- Eliminate the accuracy deviation caused by the suspension of both sides of the VMC machine table
- X, Y axis adopt to heavy load roller linear guide rail; Table operation does not exceed the base; The load stress is released evenly; solve deformation caused by long time heavy load on table of VMC machine.
- The load of table improves about 50% higher than the same specification of VMC machine.
- Z axis adopt to nitrogen balance weight, improves reaction speed and working smoothly than the counterweight of hammer in VMC machine.
- The door opening at both sides of gantry structure cover design, convenient for loading and unloading of large workpiece and processing operation.
