Product quality is at the forefront, representing the production level and development direction of China's vertical axis rotary table surface grinders, CNC vertical curve grinders, and grinding head mobile tool grinders. The vertical grinder market share reaches 60%. The company independently developed MK28 series CNC vertical internal face grinders in 2004, MK85 series CNC vertical curve grinders with a national utility model patent in 2006, and VGK CNC vertical universal grinders and CK5116 CNC vertical lathes in 2007. In 2008, CK5225 CNC vertical lathes were developed, followed by MK2880Z CNC grinders in May 2009. In 2010, MKQ7450/MKQ7475 lightweight single-axis CNC surface grinders upgraded the existing vertical axis rotary table surface grinder product line. In 2011, the MK2860TJ product developed for the valve industry overcame the machining challenge of triple-offset butterfly valve sealing surfaces. The MK72800-4.5 grinding head mobile vertical axis rectangular table surface grinder was launched for the first time, and the M7475D sector grinding stone chuck processing method and design received national invention and utility model patents, as did the linear guide adhesive injection process.
