The bed of a NC lathe is at an angle just to ensure swarf slides to the bottom of the machine for collection. They are referred to as "slant-bed lathes". The angle of the bed is dependent to the manufacturer. Some built 90 degree or vertical beds (Monarch Machine Tool Series 220 for example), and others built lathes at varying angles from horizontal, 70, 60 and 45 degrees are the most common, with 45 degrees about the shallowest angle that can be had and still have good chip flow. Other builders use a horizontal base, and use a triangular carriage to achieve the slant effect to shed chips and coolant.
