What are the advantages of inclined bed CNC lathes over flat bed CNC lathes?

CNC machine tools were born to adapt to the mass automated production of modern industrial production, and the key word is automation. The flat bed CNC lathe is transformed from the ordinary lathe with simple numerical control, and the consideration of automation is not comprehensive. The inclined bed CNC lathe is developed and designed according to the principle of CNC machining, and the pertinence is very strong, in terms of the layout, rigidity, accuracy, and chip removal capacity of the machine tool, it has been significantly improved compared with the flat bed CNC lathe.

Four advantages of inclined bed CNC lathe compared with flat bed CNC lathe:

1. High processing accuracy.

The transmission screw of the CNC lathe is a high-precision ball screw, and the transmission gap between the screw and the nut is very small, but it does not mean that there is no clearance, and as long as there is a clearance, when the screw rod moves in one direction and then reverses the transmission, it is inevitable that there will be a reverse clearance, and the reverse clearance will affect the repeated positioning accuracy of the CNC lathe, thereby affecting the machining accuracy. The layout of the inclined bed CNC lathe can directly affect the clearance of the ball screw in the X direction, and the gravity directly acts on the axial direction of the screw, so that the reverse clearance during transmission is almost zero. The X-direction screw of the flat bed CNC lathe is not affected by axial gravity, and the gap cannot be directly eliminated.

This is the innate precision advantage that design brings to the slanted bed CNC lathe.

2. The machine tool has good rigidity and is not easy to cause vibration during cutting.

The cross-sectional area of the inclined bed CNC lathe is larger than that of the flat bed of the same specification, that is, the bending and torsion resistance is stronger. The cutter of the inclined bed CNC lathe is to cut down at the oblique top of the workpiece, and the cutting force is basically the same as the gravity direction of the workpiece, so the spindle runs relatively smoothly and is not easy to cause cutting vibration, while the flat bed CNC lathe is cutting, and the cutting force generated by the tool and the workpiece is 90 ° with the gravity of the workpiece, which is easy to cause vibration.

3. Due to the relationship between gravity, iron filings are not easy to produce winding tools, which is conducive to chip removal.

Due to the relationship of gravity, the inclined bed CNC lathe is not easy to produce winding tools, which is conducive to chip removal; At the same time, with the central screw and guide rail protective sheet metal, it can avoid the accumulation of chips on the screw and guide rail.

4. High degree of automation.

The increase in the number of machine tools and the configuration of the automatic chip conveyor are actually laying the foundation for automated production. One person on duty for multiple machine tools has always been the direction of machine tool development. The inclined bed CNC lathe is equipped with a milling power head, an automatic feeding machine tool or a manipulator, automatic feeding, a clamping to complete all the chip processes, automatic blanking, automatic chip removal, and it has become an automatic CNC lathe with high work efficiency.

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

What are the advantages of inclined bed CNC lathe compared with flat bed?

First, the layout of the machine tool: the supporting plate of the inclined bed intersects obliquely with the ground plane, there are a variety of angles, the bed is a right-angled triangle from the side, it is obvious that when the width of the same guide rail, the X-direction carriage of the inclined bed is longer than that of the flat bed, and more tool positions can be arranged;

2. Comparison of cutting rigidity: the cutter of the inclined bed lathe is cut downward above the workpiece, and the cutting force is basically the same as the gravity direction of the workpiece, so the spindle runs relatively smoothly and is not easy to cause cutting vibration, while the flat bed CNC lathe is 90 ° with the gravity of the workpiece when cutting, which is easy to cause vibration;

3. Comparison of machining accuracy, the oblique bed can directly affect the ball screw clearance in the X direction, and when gravity acts on the axial direction of the lead screw to make the transmission, the reverse clearance is almost zero, and the X-direction screw gap of the flat bed can not be directly eliminated, which makes the difference in the repeated positioning accuracy between the two, and then affects the machining accuracy;

Fourth, the comparison of chip removal capacity, the inclined bed is conducive to chip removal under the influence of gravity, it is not easy to produce tool winding, and it is convenient to match, the automatic chip conveyor increases the processing efficiency, while the flat bed is difficult to achieve.

The above are the advantages of the inclined bed.

Inclined bed CNC lathe is a high-precision, high-efficiency automatic machine tool. Equipped with a multi-station turret or a driven turret, the machine tool has a wide range of processing performance, can process linear cylindrical, oblique cylindrical, circular arc and a variety of threads, grooves, worms and other complex workpieces, with linear interpolation, arc interpolation various compensation functions, and in the mass production of complex parts play a good economic effect. What are the structural characteristics of the inclined bed CNC lathe?

1. The linear rolling guide rail of the inclined bed CNC lathe meets the requirements of high speed and high efficiency, reduces friction resistance and temperature rise deformation, improves machining accuracy, and can ensure the long-term stability of cutting accuracy.

2. The tool detection device can automatically input the tool tip position data into the numerical control system, which greatly reduces the clamping time when changing the tool, and can also automatically compensate for the wear of the tool tip.

3. The inclined bed CNC lathe adopts domestic or imported high-rigidity horizontal turret turret, with high positioning accuracy and small heavy cutting deformation.

1: The inclined bed CNC lathe is easier to remove chips than the flat bed CNC lathe 2, and the electrical part is better isolated from the processing area.

3. The inclined bed CNC lathe is much more expensive than the flat bed machine tool.

4. The number of tools in the inclined bed is generally 8 knives, and the position of the tool holder is different.

5. The inclined bed is generally 45°, and the bed is cast as a whole, with good rigidity, good stability, good chip removal, fast speed and good accuracy.

1.Layout comparison The plane of the two guide rails of the flat bed CNC lathe is parallel to the ground plane. The plane where the two guide rails of the inclined bed CNC lathe intersect with the ground plane to form an inclined plane, and the angle is 30 °, 45 °, 60 ° and 75 °.

From the side of the machine tool, the bed of the flat bed CNC lathe is square, and the bed of the inclined bed CNC lathe is a right-angled triangle. Obviously, in the case of the same rail width, the X-direction carriage of the inclined bed is longer than that of the flat bed, and the practical significance of the application in the lathe is that more tool positions can be arranged.

2.Rigid comparison The cross-sectional area of the inclined bed CNC lathe is larger than that of the flat bed of the same specification, that is, the bending and torsion resistance is stronger. The cutter of the inclined bed CNC lathe is to cut down at the oblique top of the workpiece, and the cutting force is basically the same as the gravity direction of the workpiece, so the spindle runs relatively smoothly and is not easy to cause cutting vibration, while the flat bed CNC lathe is cutting, and the cutting force generated by the tool and the workpiece is 90 ° with the gravity of the workpiece, which is easy to cause vibration.

Generally speaking, the inclined bed is stronger than the flat bed CNC machine tool in terms of automation, but relatively speaking, the production of the inclined bed CNC machine tool is difficult, so both have their own advantages.

The inclined bed is a guide rail, which does not have to bear all the force, and the guide rail of 45 or 30 ° is not easy to retain iron cutting, and the guide rail will not be scratched by iron cutting when moving at high speed.

There is no difference in a bed, you should ask about the difference between a flat bed lathe and an inclined bed lathe, the degree of inclination of the bed is not the same.

Wash the center, 45 degrees on the rails. Machining centers, almost no flat. Looking at the machine, it has no effect on the accuracy.

Flat bed, inclined bed and flat bed inclined guide rail are mainly determined by their working environment and processing range.

The processing environment is good, the processing parts are small (the machine tool design and processing circumference is small), so the machine tool itself is small, and the flat bed machine tool is generally used. That is to say, small CNC lathes are generally flat beds.

And the need to process too large parts generally use inclined bed or flat bed inclined guide rail machine tool, because the corresponding components of medium and large machine tools are also very large, especially the turret part, the use of inclined guide rail is mainly to overcome gravity to have better stability to improve the accuracy of the machine tool, in some harsh environments can reflect the superiority of the inclined machine tool. There is that the inclined machine tool can effectively use the space, greatly reducing the plane occupation position of the machine tool, because some inclined machine tools are superior to the flat machine tool, but the cost is correspondingly high, because of the processing of small parts, the choice of flat machine tool is on the line.

There must be advantages!! But you don't need it in general places!! So it's not clear about the points and disadvantages!!

Is it a guide rail or a bed?

The plane you process can be tilted 30 degrees to process the hole surface tapping or something.

It's convenient and precise.

Save yourself from making another mold.

The inclination of the CNC machine bed is generally between 30° and 45°.

The advantage of the inclination of the CNC machine bed of 30° is: the center of gravity of the CNC machine tool is low, stable and high, which is conducive to improving the machining accuracy.

The advantage of a 45° inclination of the CNC machine bed is that it is conducive to chip evacuation and reduces the influence of slag on the machined parts.

Therefore, the inclination of the CNC machine bed should be comprehensively considered and evaluated according to the accuracy requirements of the processed parts and the characteristics of the processed materials.
