PANDK Bed Cooling Technology Patent

The bed cooling system effectively reduces the heat generation of the slide, reduces the coefficient of thermal expansion of the metal, and reduces the temperature difference between the slide and other components. During long-term operation, the temperature remains constant, the machining accuracy is lasting, and the processing stability is improved. An active circulating cooling system is used to quickly dissipate the heat generated by the slide during operation to reduce local overheating of the bed caused by heat accumulation, so that the bed is always at a constant temperature, thereby reducing the deformation caused by thermal expansion and contraction, thereby ensuring that the temperature is constant and the accuracy is stable during long-term operation, and improving product completion efficiency.

Wide Base, Four Guide Rails

The base area is larger than that of conventional models, ensuring the overall rigidity of the equipment and being more conducive to the stability of machine tool cutting. This model is equipped with four guide rails on the X-axis of the entire series, increasing the coverage area of the guide rails to achieve full support of the guide rails. The column is enlarged, and the internal horizontal support rib structure more effectively enhances the column strength. The four-rail base has a larger support range, and with the ultra-rigid worktable, the height from the worktable surface to the slider surface is 275mm, and it is supported by double-layer ribs, high load, not easy to deform, and the accuracy is maintained stable for a long time.

Heavy-duty Gear Head Spindle

The head adopts a central water-outlet two-stage gear head, adopts a ¢100mm spindle, chromium-molybdenum alloy steel material, after tempering, rough and fine machining, carburizing treatment, aging treatment and precision grinding; high precision, high rigidity, and not easy to deform. After the spindle is assembled, it is calibrated by dynamic balance test. The spindle box adopts a special design of high-strength and high-rigidity cage type and keel rib structure. The spindle gear gearbox adopts gear box transmission, and the maximum speed can reach 6000 rpm (15/18.5kw), which is suitable for high-speed and heavy cutting. Two-stage switching ensures the large torque required for roughing parts and meets the high speed for finishing parts or small tools.

Center Water Outlet, High-efficiency U Drill

When drilling deep holes with conventional models, it is limited by the external cooling of cutting, and only high-speed steel drills can be used. When drilling deep holes, iron chips cannot be efficiently discharged, and chips are easy to accumulate and burn tools. It is necessary to retract the tool cyclically to discharge chips, and the processed hole wall is easy to appear chip accumulation. High-speed steel is a low-speed cutting tool, which prolongs the processing time and restricts the processing efficiency. Equipped with a high-pressure central water-outlet two-stage gear head, using "U" drill processing, high-pressure central water-outlet more effectively cools the tool and workpiece, and efficiently discharges waste chips from the part to be processed, the processed hole wall is smooth, and the hole accuracy is relatively higher than that of high-speed steel drills. Processing accuracy.

High-strength column, telescopic hole

The square box reinforced structure column is used to more effectively enhance the column strength, the internal horizontal support rib structure more effectively enhances the column strength, the high-strength column is designed with telescopic holes, and the temperature difference reduces the deformation of the column. It further improves stability and improves processing accuracy. Under the working conditions of long-term operation, it effectively offsets the thermal expansion effect caused by temperature increase.

Rich Optional Configurations, Strong Expandability

Optional full closed-loop control. Four-axis and five-axis turntables can be added to realize multi-axis linkage. Optional central water outlet of the spindle, machine tool tool setting instrument workpiece measurement, and auxiliary head. It can be equipped with a 24T disc-type tool magazine or a chain-type tool magazine with the number of tools installed.
