CNC Lathe With Inclined Bed Has Three Advantages
1. High machining accuracy. CNC machine tool carriage drive screw is high precision ball screw, screw and nut between the transmission gap is very small, but also not to say that there is no gap, but as long as there is a gap, when screw in one direction and then reverse transmission, hard to avoid can produce backlash, with reverse clearance will affect machining precision, and this kind of 45 degrees of lathe bed of machine tool with the effect of gravity, gravity act directly on the screw's axial, drive when the backlash is almost zero.If you still do not understand, you can find a common nut and screw, vertical upward, twist the screw, and then reverse back, you will understand that the nut always to the side of the screw pressure, so there will be no reverse clearance, if you let the nut and screw flat, there will be no such effect.
2. Good rigidity of the machine tool, not easy to cause vibration when cutting.Because this kind of machine tool is at the top of workpiece inclined cutting, cutting force of gravity is consistent with the main shaft workpiece, so the spindle running relatively stable, not easy to cause cutting vibration, and ordinary numerical control lathe in cutting, cutting force of cutting tool and the workpiece is up, do not agree with the gravity of the spindle is generated, so it easy to cause vibration.
3. It is difficult to detangle iron filings due to gravity.
