Description

TECHNICAL FIELD

[0001] The utility model relates to numerical control milling equipment technical field especially is related to a carving and milling machine body. BACKGROUND

[0002] The carving and milling machine is a high-efficiency and high-precision numerical control milling machine equipped with small cutters, high-power and high-speed spindles. In order to alleviate the mechanical vibration caused by the high-speed rotation of the carving and milling machine, the machine base of the carving and milling machine is usually made of mineral casting. The mineral casting is a dense polymer mineral material made of different ores, fillers, epoxy resins, curing agents and other materials, which has the advantages of corrosion resistance, reduced thermal deformation and reduced equipment vibration.

The mineral casting carving and milling machine base includes a loading platform and a gantry. The gantry is screw-mounted on the loading platform. The utility model optimizes the structure of the gantry of the carving and milling machine. The inclined structure of the upper end surface of the gantry reduces the strength requirement of the reinforcing member when connecting the spindle, because the gantry shares the lateral stress of the reinforcing member. This allows the spindle to be close to the gantry, so that the working stroke of the driving installed on the translational loading block is fully utilized, ensuring the utilization rate of the driving slide rail. In addition, the pre-buried expansion thread sleeves on the outer wall of the platform body can reduce material consumption and expand the auxiliary equipment of the carving and milling machine under different working conditions, so that the carving and milling machine body has high flexibility.
