What Are The Advantages of Flat Bed CNC Lathe?

Flat Bed CNC Lathe refers to a flat bed CNC lathe. The following is an introduction to it:

Structural characteristics

Bed structure: The two guide rails of the bed are parallel to the ground plane and appear square when viewed from the side.

Adopting high rigidity design: High load rectangular guide rails are commonly used, optimized for dynamic performance, anti warping and seismic resistance during heavy cutting. For example, some large mechanical processing enterprises use flat bed CNC lathes, which can maintain smooth operation when processing large steel parts.

Extreme collision prevention and protection: There is a rubber buffer collision prevention device at the extreme travel position of the positive and negative directions of the shaft to protect the double nut ball screw pair. Fully protected sheet metal design, with stainless steel telescopic covers used for guide rails, screws, etc. in the internal protection.

Technical advantages

High precision: The flat bed design enhances the overall rigidity of the machine tool, reduces machining vibration, and helps maintain the precise position of the tool and workpiece. High precision electric spindle and servo driven feed system ensure high precision and stability in machining.

High efficiency: The combination of CNC system and servo drive can achieve fast positioning and high feed speed, shortening the production cycle. The spindle speed is high and the frequency conversion speed range is wide. For example, T+32 adopts a frequency conversion motor and frequency converter control, with automatic switching between high, medium, and low speeds, and the program can run continuously.

Multifunctional: Through programming control, it is easy to switch between different processing programs, adapt to various materials and shapes of workpieces, and can process complex shaped workpieces such as curves, spirals, and spheres.

application area

Automotive manufacturing: capable of processing high-precision engine components, transmission shafts, and other key automotive parts.

Aerospace: High strength material components used to manufacture complex geometric shapes such as aircraft engine blades and fuselage structural components.

Medical devices: Their high-precision processing capability can meet strict requirements for implants, surgical instruments, etc.

Other fields: It is also widely used in industries such as electronics, instrumentation, and general machinery, such as processing precision shaft parts in electronic equipment and small precision parts in instrumentation.

Disadvantages compared to inclined bed CNC lathes

Difficulty in chip removal: The flat bed structure is not conducive to chip removal, and chips are prone to accumulate on the guide rails and screw rods, affecting the accuracy and service life of the machine tool. It is also difficult to install an automatic chip removal machine.

Limited machining accuracy: The X-direction lead screw is not affected by axial gravity, and the reverse clearance between the lead screw and nut cannot be directly eliminated. Its repeatability accuracy is slightly inferior to that of inclined bed CNC lathes.

Low degree of automation: Compared to inclined bed CNC lathes, it is at a disadvantage in achieving automated production, with relatively fewer tool positions and greater difficulty in configuring automatic feeding and chip removal devices.
