slant bed CNC lathe flat bed CNC lathe What’s the difference?   China Machine Tool Business Network Tracy:   slant bed CNC lathe peaceful bed CNC lathe machine layout Contrast:  flat bed CNC lathes, two rails parallel to the plane and the ground plane. Slant bed CNC lathe two rails and the plane of the ground plane intersect into a bevel angle has 30 °, 45 °, 60 °, 75 ° points. From the machine side, flat bed CNC lathe bed was a square, slant bed CNC lathe bed right-angled triangle. Obviously, under the same circumstances rail width, slant bed to the X carriage than the flat bed is longer, in practical significance is that it can arrange more lathe knives digit   slant bed CNC lathe bed CNC peace lathe machine cutting rigidity contrast:  slant bed CNC lathe large cross-sectional area than the flat bed of the same size, that is resistance to bending and torsional ability. Slant bed CNC lathe tool is diagonally above the workpiece is cut down, consistent with the direction of cutting force of gravity and the workpiece, so the spindle running relatively smoothly, cutting unlikely to cause vibration, and flat bed CNC lathe cutting tool and cutting force of gravity with the workpiece into the workpiece 90 °, easy to cause vibration.   Slant bed CNC lathe flat bed CNC lathes machining precision Contrast:  CNC lathe screw drive are high precision ball screw, lead screw and nut drive gap between the small, but it is not that there is no gap, as long as there is a gap, when the screw towards one direction and then reverse drive, will inevitably produce backlash, there is backlash will affect the repeatability of CNC lathes, thus affecting the machining accuracy. Gap slant bed CNC lathe can directly affect the layout of the X-direction ball screw, gravity acts directly on the axial screw, so that backlash when the drive is almost zero. X direction flat bed CNC lathe axial screw is not the influence of gravity, the gap can not be directly eliminated. This is designed to slant bed precision CNC lathes bring inherent advantages.   Slant bed CNC lathe flat bed CNC lathes machine tool chip capacity comparison:  because the relationship between gravity slant bed CNC lathe is not easy winding tool, which will help chip; in conjunction with the center screw and sheet metal guard rails, can be avoided in the chips stacking the screw and guide rail. Slant bed CNC lathes are generally configure automatic chip conveyor, can automatically remove the chip, increasing the effective working time workers. Flat bed structure is difficult to adding automatic chip conveyor.   Slant bed CNC lathe peaceful bed CNC lathe machine automatic production of contrast:  configuration machine tool-digit increases, automatic chip conveyor, in fact, are laying the foundation for the automation of production. One unattended more than one machine, the machine has been the direction of development. Slant bed CNC lathe and then the addition of milling power head, automatic feeder bed or robotic, automatic feeding, a fixture to complete all of the steps chips, automatic cutting, automatic chip removal, it would be very efficient automatic CNC lathes. Flat bed CNC lathe structure at a disadvantage in terms of automation. Although slant bed CNC lathe comprehensive advanced than the flat bed CNC lathes, but the market share is far behind. Advantages flat bed CNC lathe production and other easily occupy more than 90% of the CNC lathe market share.
