            ADD: High-tech Industrial Development Zone, Jinan

            Jinan No.4 CNC Machine Tool Co., Ltd. (formerly known as Jinan Fourth Machine Tool Works), founded in 1938 with a registered capital of RMB 10 million and total assets of RMB 120 million, is the sole Gold Medal Winner for National Excellence in domestic cylindrical grinder industry. It is located in High-tech Industrial Development Zone, Jinan and covers an area of about 180,000m2. Chairman Mao checked our first M135 cylindrical grinder at Beijing Zhongnanhai Machine Tool Exhibition held by the First Machine Building Industry in 1958. The company has been rated as “Shandong High-tech Enterprise, Shandong AAA Standardization Good Behavior Enterprise, Shandong CNC Grinding Machine Engineering Technology Research Center, Jinan Famous Trademark, Jinan Contract-honoring& Promise-keeping Enterprise, Jinan High-tech Enterprise, National Customer Satisfied Product in Mechanical Industry” and other honorary titles since 2005 and “Shandong Famous Product” in 2011. Our products are well sold in 30 provinces, cities and autonomous regions in China, and exported to 22 countries and regions, including America, Germany, South Korea, etc.
             The company now has 442 employees, average annual earnings of RMB 31,200/person in 11 years, and profit of RMB 4.49 million and profit and tax of RMB 13.17 million in 2011, and anticipated profit of RMB 5.84 million and profit and tax of RMB 13.6 million in 2012. Our products mainly include three series (125 series, 200 series, 320 series), 23 varieties and 69 specifications of cylindrical grinders, CNC cylindrical grinders and special cylindrical grinders and internal grinders, and are widely used for automobile, motorcycle, oil pump nipple, war industry, space flight and aviation, instrument, textile and other basic parts production industries. The newly developed MKS1632*1500 CNC cylindrical grinder and CNC internal grinder have been widely used in the market in recent years, and “Jisiji” grinder has become the first brand for users. Our products develop from small specification to large and medium specification, ordinary type to high-precision and high-speed enclosed and CNC types, and end face mill to cam mill, bent axle mill, gear mill, bore mill, compound mill and turret compound mill, and partial high-tech molding products fill in domestic blank and replace imported products. Product technologies are internally advanced, and some key technologies have reached international level, wherein CNC high-speed cylindrical grinder and CNC high-precision cylindrical grinder adopt multiaxial linkage CNC system, built-in PLC color LCD, grinding wheel mainshaft bearing with three tiles structure and integral taper molding oil wedge hydrodynamic bearing and radial automatic measuring instrument for online detection, achieve automatic milling cycle, ensure high grinding dimensional precision, and are suitable for high-precision grinding of precision shafts and plate and shell type parts, especially contour machining of complex curves and multi-profile combined machining of wide grinding wheel. Grinding carriage, headstock and work table of common cylindrical grinder can rotate at an angle, work table longitudinal reciprocating motion can adopt manual or hydraulic stepless speed regulation, and grinding carriage can be used for rapid advance and retreat, so common cylindrical grinder is suitable for grinding outer cylindrical surfaces, outer conical surfaces, bore and inner conical surfaces and ledges of medium and small shafts, sleeves and flange plates, and eccentric shaft necks of single and crank shafts in automobile and motorcycle industries.
             In recent years, the company has developed and formed key technologies which have proprietary intellectual property rights and stand for core competitiveness and through technological introduction, joint development, independent innovation and other new ways, establishing measuring benchmark and scale of technical indexes in the industry. Since 2009, our company has obtained the following honors: Diesel engine oil nozzle grinding automatic production line obtained the second award of Shandong Mechanical Industry Scientific and Technological Progress in July 2010, J4K-071 series diesel engine oil nozzle grinding automatic production line obtained Jinan Technical Innovation Award in December 2010, our company assumed 2010 third groups of Shandong technological innovation projects MKS1620*630 and MKS1320/1CBN*500 and passed the identification of Shandong economic and information technology, assumed the fourth group of Shandong technological innovation projects MK215 and passed the identification of Shandong economic and information technology, assumed 2010 High-tech Zone technology plan project J4K-083 and passed the identification of Jinan Technology Department, assumed 2009 Jinan youth star plan MGK1620*350 CNC high-precision end face cylindrical grinder and passed the identification of Jinan Technology Department, assumed 2009 Shandong technological innovation project-diesel engine oil nozzle grinding automatic production line and passed the identification of Shandong Economic and Trade Department, and assumed 2009 Shandong technology development plan J4K-071 series diesel engine oil nozzle grinding automatic production line and passed the identification of Shandong Technology Department, etc.
