Advantages of Carbide drill with coolant through

The various carbide drill with internal coolant made of solid carbide are specially designed for high-speed hole processing. Its characteristic is that there are two burr holes in the direction of flower rotation from the shank to the cutting edge. Compressed air, oil or liquids are passed through during processing to trigger a reaction. The drill bit coating can be coated on the surface to improve the coating and processing size of the drill bit. Therefore, a cold drill bit that can be drilled inside can be harder than a hard coat. High-quality alloy drills have better material processing performance, especially suitable for deep holes and difficult-to-process materials. When using a small number of drills for high-speed processing, due to the influence of tropical climate, the appearance of drills and products will bring you high-speed and high-energy bricks. Welcome to use exterior or custom-made internal cold hole drills.

ROYI Participate in the metal cutting exhibition

Royi participated in CME 2021 metal cutting exhibition. The 2021 CME Shanghai International Machine Tool Show attracted more than 1,500 brand companies from all over the world to compete on the same stage in five fields: metal cutting, metal forming, grinding tools, machine tool accessories, and smart factories. The total exhibition area exceeded 130,000 square meters. At the same time, the number of visitors broke a record high, reaching 130,000/time, a year-on-year increase of 12% May 6-8, 2021, Shanghai Hongqiao National Convention and Exhibition Center, CME Shanghai International Machine Tool Show will continue to shoulder its mission to promote the internationalization and globalization of Chinese manufacturing enterprises. Relying on the huge market demand in the Yangtze River Delta and Shanghai's unique economic position, CME Shanghai International Machine Tool Show will surely become one of the largest machine tool exhibitions in China.

Methods to reduce wear during tool processing

Precautions for tool processing When using ball nose end mill, it should be noted that the cutting speed near the center is extremely small, close to "zero", so the cutting conditions are relatively harsh. Therefore, if possible, there should be an inclination angle between the axis of the milling cutter and the normal direction of the workpiece. According to experiments, when the included angle is about 15°, the life of the tool will reach a maximum value. When milling the internal cavity, when the tool is fed to the corner, the radial force will increase sharply due to the sudden increase of the cutting wrap angle, and the peak value will reach about 170% of the normal cutting value. Therefore, we recommend The so-called "trochoidal cutting" is implemented at various locations, so that a sudden increase in cutting force can be avoided.
