Description

Technical Field

[0001] The utility model belongs to the technical field of numerically controlled lathes, and more specifically, particularly relates to a numerically controlled lathe with water outlet at the center of a spindle. Background Art

[0002] The CNC lathe processes parts by controlling the turning device through programming. The parts are clamped in the chuck, and the CNC lathe runs the programming so that the spindle drives the chuck to rotate at high speed, and the turning device drives the tool to move to complete the processing of the parts.

[0003] According to the application number: CN201821192168.7, an improved CNC lathe disclosed includes a permanent magnet servo motor, a three-phase power supply circuit, a short-circuit closed circuit, a switching switch and a brake controller. When the permanent magnet servo motor is powered off, the brake controller controls the switching switch to disconnect the three-phase power supply circuit, and at the same time controls the switching switch to connect the short-circuit closed circuit. At this time, the permanent magnet servo motor is in a short-circuit state, and the coil of the permanent magnet servo motor is subjected to a reverse force. The reverse force makes the output shaft of the permanent magnet servo motor rotate in the opposite direction to the screw rod, that is, the moving parts will not slide down at this time. This braking method adopts circuit control, thereby improving the braking efficiency of the moving parts, fast response, and flexible control. In addition, the CNC lathe is also provided with a protective cover for shielding machining chips, the center of gravity of the spindle is lower, and the stability of the spindle operation is improved. The bottom end of the bed is provided with a base in the shape of a well and a triangle, which is more stable.

[0004] Based on the above, existing CNC lathes will generate metal debris during the processing of parts. The strips of metal debris are easily entangled on the outside of the processing tool, wearing the parts during processing, affecting the processing of the parts and easily causing quality problems.
