Recently, Guiyang Xianfeng Machine Tool Co., Ltd. (referred to as "Guiyang Xianfeng") was invited to participate in Highly anticipated The 13th China CNC Machine Tool Exhibition (CCMT2024). This exhibition is a significant event in the Chinese CNC machine tool industry, held again after a two-year hiatus. With an unprecedented scale, it has become a grand gathering in the global machine tool and equipment sector, attracting nearly 2,000 machine tool enterprises from 28 countries and regions worldwide. Enthusiastic Participation. Representatives from across the global industry—including manufacturers, buyers, distributors, industry associations, professional organizations, and news media—gathered together to jointly witness the grand opening of this momentous industry event.

This exhibition features a wide range of exhibits, covering metal cutting machine tools, metal forming machine tools, special machining machine tools, laser processing equipment, additive manufacturing and specialized equipment; manufacturing cells/systems, industrial robots and automation equipment; CNC systems, digital display devices, and machine tool electrical components; abrasives and grinding tools, superhard materials and products, coated abrasive tools; and wood and bamboo processing machine tools. and other fields Guiyang Xianfeng invested a great deal of effort during the early preparation stage. Blood will ultimately showcase the MK11150 wide-grit precision CNC centerless grinder at this grand event.

The MK11150 wide-grinding-wheel precision CNC centerless grinder boasts exceptional grinding performance and a broad range of applications. It can process workpieces with diameters ranging from φ20 to φ150 mm, and its maximum grinding length reaches 300 mm. In terms of grinding wheels, this machine supports grinding wheels with maximum dimensions of P600×500×305 mm and minimum dimensions of P480×500×305 mm. Meanwhile, the guide wheels have maximum dimensions of P350×500×203 mm and minimum dimensions of P300×500×203 mm. Notably, this machine features a grinding wheel peripheral speed as high as 35 m/s, and its X-axis minimum feed rate is accurate to within 0.001 mm.

By adopting the plunge grinding technique, the MK11150 wide-wheel precision CNC centerless grinder can achieve highly accurate grinding operations. Taking a test piece with dimensions of φ30×300 as an example, this machine can grind it to a working accuracy of 0.01 to 0.03 mm, with roundness controlled within 0.001 mm and cylindricity controlled within 0.002 mm. Moreover, the surface finish of the workpiece after grinding is exceptionally smooth, reaching a standard of Ra ≤ 0.32 μm. These outstanding performance indicators make the MK11150 wide-wheel precision CNC centerless grinder an ideal choice for high-precision grinding applications.
