CNC milling machine can be used in the part of machining shape complexity, and the price of a number of units control milling machine will well below the price of a numerical control machining center.But there is a problem in CNC milling machine, in process, when the electric motor load torque of synchronous motor is greater than the torque that motor can provide, motor speed does not catch up with the synchronous speed of motor, occur " step-out " phenomenon when CNC milling machine Z-direction can be caused to be elevated, thus when causing processing parts, precision can not get ensureing.
Utility model content
For above-mentioned shortcoming and defect of the prior art, the purpose of this utility model is to provide a kind of CNC milling machine that can adjust processing platform station effectively can solve the CNC milling machine of " step-out " problem when Z-direction is elevated, improve the stable working degree of CNC milling machine, improve the precision of processing parts.
The purpose of this utility model is achieved through the following technical solutions:
A kind of CNC milling machine, comprises support, column and digital control system, the mair motor that column is provided with Z axis slide rail and is connected with digital control system; Described Z axis slide rail is provided with the transmission mechanism connecting mair motor and main shaft, and transmission mechanism slides along Z axis slide rail, and main shaft is connected with milling cutter; Also comprise counter weight device and guider, described guider is fixed on rear side of column, and guider comprises pair of parallel guide pillar; Described counter weight device comprises balance weight body, described balance weight body offers two through holes matched with guide pillar, described guide pillar runs through through hole and balance weight body can be moved up and down along guide pillar, balance weight body is fixedly connected with a cable wire, cable wire is fixedly connected with transmission mechanism through the pulley be fixed on column.
Preferably, described support is provided with workbench, and workbench is provided with slide and rotary table; Described workbench is provided with handwheel, handwheel with connecting rod be connected with rotary table.
