Large and ultra-large wire cutting, precision casting high-speed train brake disc cooling fins

Behind the high-speed trains, the braking system is the ultimate guardian of safety. Every precise braking is inseparable from the seemingly inconspicuous but crucial cooling fins on the brake disc. Their birth is closely linked to large and ultra-large wire cutting equipment and machine tools. Today, we will unveil the veil behind this precision manufacturing. Stepping into the production core area of a company focusing on high-speed train braking, the processing of cooling fins on the brake disc immediately shows extremely high difficulty. As a key component that withstands huge friction and converts the kinetic energy of the train into thermal energy, the cooling fins are responsible for quickly dissipating heat and preventing the brake disc from overheating and failing. A standard cooling fin may be only a few millimeters thick, but fine and uniformly deep grooves must be cut on it to increase the heat dissipation area. According to actual production measurements, the groove spacing accuracy must be controlled within ≤±0.00 3 mm , and the depth tolerance must not exceed ≤±0.00 3 mm . Such strict standards are only to ensure maximum heat dissipation efficiency. In addition, the heat sink fins are mostly made of high-strength alloy materials, which must not only have excellent high-temperature resistance, but also ensure that their own structure is stable under high-speed rotation and severe vibration conditions. This alloy material has high hardness and high toughness. Conventional cutting methods are very likely to cause tool wear and rough processing surface, which cannot meet the strict requirements of the brake system for reliability and stability. Large and ultra-large wire cutting equipment machine tools rely on the unique principle of discharge machining to cleverly avoid the bottleneck of material hardness. Through high-frequency pulse current, instantaneous high temperature is generated between the electrode wire and the workpiece, material is etched, and perfect grooves are accurately "carved" on the hard alloy. In the high-speed train braking system, there are many similar parts with many challenges. For example, the key connectors of the brake caliper must withstand huge clamping forces and are repeatedly stressed during frequent braking. The strength, toughness and processing accuracy are extremely high; and the piston rod of the brake cylinder not only requires high-precision cylindricity, but also excellent wear resistance and corrosion resistance to operate stably and for a long time in complex environments. Faced with these "hard bones" in the industry, Zhikai CNC stands out with its profound heritage. Over the years, Zhikai has invested heavily in research and development, and its scientific research team has worked with industry experts to overcome many technical difficulties.
