Abstract

The invention provides a double-spindle and double-speed composite NC milling machine and pertains to the field of mechanical processing technology. The invention consists of a main power spindle, a high-speed motorized spindle, a spindle box for arranging the main power spindle and the high-speed motorized spindle, an upright column, a workbench, a bed saddle, a bed body, a servo motor, a servo drive and a NC system. The invention is characterized in that the main power spindle and the high-speed motorized spindle are arranged in the spindle box; the spindle box is supported on the guide rail of the column and can slide along a guide rail; an X-shaft motor is arranged on the bed saddle so that the workbench can move horizontally and a Y-shaft motor is arranged on the bed body so that the bed saddle can move back and forth; a Z-shaft motor is arranged on the column to drive the spindle box to move in a straight-line way; the NC system consists of a controller, a system input I/O unit, a system output I/O unit, a servo amplifying unit and a system bus for connecting these parts; a cooling system is a series-wound oil cooling circuit. The invention increases the processing efficiency and also reduces the cost.

Description

Technical field: [0001] The invention relates to a double-spindle double-speed composite numerical control milling machine, which belongs to the technical field of mechanical processing. Background technique: [0002] In the field of metal cutting, ordinary vertical milling centers are widely used. It has large output torque, high processing efficiency, and multiple functions such as milling, drilling, boring, reaming, and tapping. It has strong rigidity and stability, strong heavy cutting ability, and the spindle speed of ordinary machining centers Usually lower than 8000rpm, due to the low spindle speed, high-speed precision machining cannot be performed, and the surface finish of the processed workpiece is poor. High-speed machining centers, because of the built-in high-speed spindle, the spindle speed can reach more than 20,000rpm, which can be used for fast machining, high-precision and ultra-fine surface machining of parts, but due to the characteristics of the motor,...
