1、The main structural castings of the machine tool are precision cast by advanced German resin sand production line, with thin wall and multiple ribs, reasonable reinforcement, stable organization, and compact structure, so that the machine tool has enough stiffness to ensure that the machine tool can carry out full load cutting.
2、The three feed direction guide rails of the machine tool are rectangular guide rails, using cast iron quenched polytetrafluoroethylene sliding guide pairs, servo motor drive precision ball screw, so that the dynamic characteristics and accuracy of the machine tool are good, and the screw is pre-stretched during installation, which improves the axial stiffness, eliminates the thermal expansion error, and ensures the high precision of the transmission; And a fixed quantity and sufficient lubricating oil, so that the accuracy of the machine can be maintained for a long time.
3、The main shaft broach mechanism adopts the principle of unloading and loosening the knife. The spindle bearing is not stressed when the knife is loosened, so that the spindle accuracy is better maintained.
4、The bed is also equipped with a low-pressure air cleaning system, which blows air through the center of the spindle during tool change to clean the tool handle and extend the life of the spindle.
