2. The X, Y and Z axis of the machine are all guided by linear roller guide pairs, which has extremely high bearing capacity and superior dynamic response performance, no gap and high motion accuracy. 3. The worktable of the machine is separated from the bed, so that the clamped material will not be affected by the vibration of the bed. The worktable is made from cast iron with stable precision. 4. The machine has two spindles, which can work at the same time. The efficiency of the machine is nearly double that of the single spindle machine. 5. The machine is equipped with a flat chain type automatic chip remover. The iron chips generated by the drilling tool are sent to the chain type chip remover through the chip removal conveyor, and the chip removal works automatically.
6. The machine is equipped with automatic lubrication system, which can regularly lubricate the parts to be lubricated such as guide rail and screw, effectively ensuring the stable operation of the machine and improving the service life of each part. 7. Simens828D/ FAGOR8055 numerical control system is adopted in the machine numerical control system, which is equipped with electronic hand wheel, so it is convenient for operation and maintenance.| NO | Name | Brand | Country |
