Slant bed CNC lathe flat bed CNC lathes price

    Domestic commonly known as flat bed CNC lathe is economical CNC lathes, CNC lathes or simple. The universal CNC lathes and CNC lathes are fully functional slant bed body. Which can be analyzed, slant bed CNC lathe than grade flat bed CNC lathe is higher. CNC machine tools in order to adapt to modern industrial production volume automated production of birth, keyword is automation. Flat bed CNC lathe is to be simple numerical transformation from consideration in automation incomplete from ordinary lathes. Slant bed CNC lathe is designed according to the principles developed NC machining of highly targeted, the machine layout, rigidity, accuracy, and chip capacity, than the flat bed CNC lathes have been significantly improved, these advantages are womb brings the inherent advantages, can not depend on manufacturing means reduced.

Machine Layout comparison:

Flat bed CNC lathes, two rails parallel to the plane and the ground plane. Slant bed CNC lathes, 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, at the same width of the rail, the inclined bed of the X carriage than the flat bed is longer, in practical sense lathe can arrange more tool positions

Cutting rigidity comparison:

Slant bed CNC lathe cross-sectional area than the same size of a large flat bed, the 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, the spindle running relatively smoothly, cutting unlikely to cause vibration, and flat bed CNC lathe cutting tool and cutting force and the workpiece is generated by gravity into a 90 °, easy to cause vibration.

Machining accuracy comparison:

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, but as long as there is a gap, when the screw towards one direction and then reverse gear when, inevitably will 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 without axial screw the influence of gravity, the gap can not be directly eliminated. This is designed to slant bed CNC lathes bring advantages inherent accuracy

Chip capacity Contrast:

Because of gravity slant bed CNC lathe is not easy winding tool, which will help chip; in conjunction with the center screw and the sheet metal guard rail to avoid the accumulation of chips in 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

Automatic production of comparison:

Machine tool number increases, configure automatic chip conveyor, in fact, are laying the foundation for the automation of production. One person on duty 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 steps of the chip, 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 low price, easy production of CNC lathes occupy more than 90% market share.
Relatively speaking, the shortcomings slant bed CNC lathe is difficult to manufacture high bed weight, X needs to servo motor with brake function, the most critical is the high cost. China is currently manufacturing to low-end products are mostly less demanding precision machine tools, the price factor is dominant when buying the machine. Cheap is the last word.
