The difference between inclined bed CNC lathe and flat bed CNC lathe

There are some differences between inclined bed CNC lathes and flat bed CNC lathes in terms of structure, performance, processing application, etc., as follows:

Structural design

Inclined bed: The bed is inclined, usually at an angle of 30°, 45°, 60° or 75° to the horizontal plane. This design makes the overall structure of the machine tool more compact, convenient for chip removal, and the chips can slide down automatically by gravity, and are not easy to accumulate on the workbench, thereby reducing the impact on the processing accuracy, and also facilitating the recovery and reuse of coolant.

Flat bed: The bed is placed horizontally, with a simple structure, relatively easy to manufacture and install, and low cost. However, due to the inconvenience of chip removal, a special chip removal device needs to be equipped, otherwise the chips are easy to accumulate on the workbench and guide rails, affecting the processing accuracy and the service life of the machine tool.

Rigidity and stability

Inclined bed: The structure of the inclined bed CNC lathe has certain advantages in rigidity and stability. The inclined bed makes the force distribution of the guide rail more uniform, can withstand greater cutting force and torque, and is suitable for heavy cutting and high-precision processing. At the same time, the overall structure of the inclined bed is conducive to reducing vibration and improving the quality of the machining surface.

Flat bed: The rigidity of the flat bed is relatively weak, especially when performing large-volume machining or high-speed cutting, it is easy to vibrate and affect the machining accuracy. In order to improve the rigidity of the flat bed machine tool, it is usually necessary to increase the thickness of the bed or adopt structures such as reinforcing ribs, but this will increase the cost and floor space of the machine tool.

Machining accuracy

Inclined bed: Since the inclined bed has good rigidity, stability and chip removal performance, it can effectively reduce various error factors in the machining process, so it usually performs better in terms of machining accuracy and is suitable for machining parts with high precision requirements, such as aerospace parts, precision instrument parts, etc.

Flat bed: Although the flat bed CNC lathe can also meet the machining tasks with general precision requirements, its precision retention may not be as good as the inclined bed machine tool when machining high-precision parts. However, for some simple parts or mass production with low precision requirements, the flat bed lathe can still play its cost-effective advantages.

Operation and maintenance

Slant bed: The operation panel of the slant bed machine is usually located on the right side of the machine, which conforms to the principle of ergonomics and is easy to operate. In addition, the structure of the slant bed makes the internal space of the machine relatively large, which is convenient for maintenance personnel to carry out maintenance and maintenance work. However, due to the complex structure of the slant bed, its maintenance cost may be slightly higher than that of the flat bed machine.

Flat bed: The operation of the flat bed CNC lathe is relatively simple, and the operator can approach the processing area more conveniently. However, due to the requirements of chip removal devices and guide rail protection, its maintenance work may be relatively cumbersome. When performing maintenance operations such as guide rail lubrication and chip cleaning, more attention should be paid to details to ensure the normal operation of the machine tool.

Scope of application

Slant bed: It is suitable for processing parts of various complex shapes, such as rotating body parts, disk parts, shaft parts, etc., especially when processing high-precision and high-difficulty parts. In addition, slant bed CNC lathes are also widely used in automobile manufacturing, mold manufacturing, electronic equipment manufacturing and other industries.

Flat bed: suitable for processing some parts with simple shapes, such as ordinary cylindrical surfaces, planes, threads, etc. Flat bed CNC lathes have been widely used in some occasions where the processing accuracy is not high and the production efficiency is high, such as general mechanical processing, hardware processing and other
