Machine tool with inclined guide rails

The invention provides a machine tool with inclined guide rails, which belongs to the mechanical technical field, and solves the problem that a lead screw of an existing machine tool with inclined guide rails is liable to wear and easily affects processing precision. The machine tool with the inclined guide rails comprises a bed stand, a spindle base and a guide rail base, wherein guide rails which are inclined downwards are arranged on the guide rail base; a turret device is arranged on the guide rails in a sliding mode; a lead screw is arranged on the guide rail base; a first nut which is in threaded fit to the lead screw is arranged on the turret device; a partial-pressure mechanism is further arranged on the turret device; the partial-pressure mechanism comprises a slide block, a second nut and an elastic part; the slide block can slide relative to the turret device in the length direction of the guide rails; the second nut is fixedly arranged on the slide block and is in threaded fit to the lead screw; a
