The CNC parallel lathe machine has been continuously improved according to the customers' years of experience in lathes, and the design failure rate is low, which has attracted wide attention of the market.

? The difference between flat CNC parallel lathe machine and slat CNC parallel lathe machine?

CNC parallel lathe machine is to adapt to the modern industrial production of batch automation production, the key word is automation.

Flat CNC parallel lathe machine is a simple CNC transformation from ordinary lathe, which is not fully considered in automation.

Slat CNC parallel lathe machine is developed and designed according to the principle of nc machining.

In layout, rigidity, precision of the machine tool and chip removal ability, than the flat CNC parallel lathe machine has improved significantly, these advantages are born with congenital advantage, can not shrink on manufacturing means.

Fu Sheng Jin CNC parallel lathe machine has summarized the four advantages of slat CNC parallel lathe machine compared to flat CNC parallel lathe machine.

1.high precision processing.

The drive screw of CNC parallel lathe machine is a high precision ball screw rod. The transmission gap between the screw rod and the nut is very small, but it is not that there is no gap. And as long as there is gap, when screw in one direction and then reverse transmission, hard to avoid can produce backlash, with reverse clearance can affect the repositioning precision of the numerical control lathe, so as to affect the machining accuracy.

The layout of slat CNC parallel lathe machine can directly affect the clearance of ball screw rod in X direction, and the gravity directly affects the axial direction of the screw rod, so that the reverse clearance of the transmission is almost zero. The X direction of the flat CNC parallel lathe machine is not affected by the axial gravity, and the clearance cannot be eliminated directly.

This is the inherent precision advantage brought by the design to slat CNC parallel lathe machine.

2.The CNC parallel lathe machine is rigid, it is not easy to cause vibration when cutting.

Slat CNC parallel lathe machine has a larger cross-sectional area than the same size, which is more resistant to bending and twisting.

Slat CNC parallel lathe machine tool from the workpiece cutting down above the diagonal, direction of cutting force and the gravity of the artifacts, so the spindle running relatively stable, not easy to induce vibration cutting, flat CNC parallel lathe machine when cutting, cutting tool and cutting force produced by the artifacts and artifact gravity into 90 °, easy to cause vibration

3.Iron filings are not easily produced by the relationship of gravity, which is good for cutting.

Because of gravity, slat CNC parallel lathe machine is not easy to produce winding tools, which is conducive to the removal of cuttings. Meanwhile, it is possible to avoid the accumulation of shavings on the screw and guide rails in combination with the medium and guide rail protection sheet metal.

4.High degree of automation

The increase of CNC parallel lathe machine tool number, the configuration of automatic chip removal machine, is actually the basis for automatic production. One person is on duty multiple machine, always is the direction of machine development.

Slat CNC parallel lathe machine with milling power head, automatic feeding machine or manipulator, automatic feeding, a clamping completed all of the scrap process, automatic cutting, automatic chip removal, becomes the high efficiency of CNC parallel lathe machine.

Although the flat CNC parallel lathe machine can also increase the power milling head and automatic feeding, its structure is at a disadvantage in automatic production.

? The basic requirements and structure types of CNC parallel lathe machine bed

The basic requirements of CNC parallel lathe machine bed

CNC parallel machine bed is the basic supporting part of the whole machine tool, which is used to place the important parts such as guide rail and spindle box.

In order to satisfy the CNC parallel lathe machine high speed, high precision, high productivity, high reliability and high degree of automation, compared with the ordinary machine tool, CNC parallel lathe machine should have higher static and dynamic stiffness, vibration resistance.

CNC parallel machine bed provides higher requirements in the following four aspects.

1.High precision and precision retention.

On CNC parallel lathe machine bed there are a lot of installed parts processing surface and of guide rail for the moving parts required the high precision and position accuracy, and must keep for a long time.

In addition, all static and dynamic loads of CNC parallel lathe machines are often transferred to CNC parallel lathe machine bed, so the stress on the CNC parallel lathe machine bed is very complicated.

In order to ensure the parts position accuracy or relative motion accuracy, in addition to meet the requirements of precision location of geometry size, you also need to meet the static and dynamic stiffness, vibration resistance, thermal stability and the process of technical requirements.

2.Sufficient static and dynamic stiffness should be provided.

Static stiffness includes: the structure rigidity, local stiffness and contact stiffness of CNC parallel lathe machine bed, and corresponding measures should be taken to achieve a high quality ratio.

Dynamic stiffness directly reflect the CNC parallel lathe machine dynamic characteristics, in order to ensure that CNC parallel lathe machine under the action of alternating load has higher resistance to deformation ability and forced vibration and self-excited vibration resistance ability, can be appropriately increased damping, and the measures of improving the natural frequency to avoid resonance because of the thin wall vibration and noise.

3.Good thermal stability.

For CNC parallel lathe machine, especially high precision CNC parallel lathe machine, thermal stability has become a prominent problem, must be in design thermal deformation is small, so the or make thermal deformation have less effect on the machining accuracy
