Description

[technical field]

[0001] The invention relates to the mechanical field, in particular to a novel numerically controlled machine tool. [Background technique]

[0002] The CNC machine tools on the market now have problems such as low rigidity, poor vibration resistance, large sliding friction resistance, and gaps in transmission components. Parts, but the failure rate is still high, it is difficult to meet the overhaul acceptance standard with traditional repair solutions, and the cost is high. [Content of the invention]

[0003] The present invention provides a new type of numerically controlled machine tool in order to meet the requirement of stable and reliable machine tool and low failure rate operation.

[0004] In order to achieve the above purpose, a new type of CNC machine tool is designed, including the spindle box of the main shaft, the bed, the control box and the tailstock. The output end of the motor is connected with a reducer, and the horizontal and vertical...
