GSM is shorted for Shaanxi Golden Stone Machinery Manufacturing Co.,Ltd., one High-tech enterprise as well as Metal Material Deep Hole Drilling Technology & Application Project Laboratory of Xian City which is specialized in designing, manufacturing and marketing of deep hole drilling machines, gun drilling tools, auxiliary equipment and machine tool accessories for decades. Besides, GSM is supported by National Innovation Fund.
The processor of GSM is Xian Machine Tool Factory, pointed by the former National Machinery Industry Ministry in manufacturing deep hole drilling machine(diameter no bigger than 30mm) for 30 years and metal cutting machine for 50 years.
In 2004, after the restructure of the factory management, Shaanxi Golden Stone Machinery Manufacturing Co.,Ltd .(GSM) has been established with ISO9001:2008 certification. GSM workshop has occupied more than 3800m2 area and equipped with advanced manufacturing devices. Professional R&D Team ensures GSM being a leading company in technology development and deep hole drilling machine design of China. After-sale Engineer Team is consist of engineers with decades experiences in drilling machine installation, commission and training, etc .to make clients purchasing without any after-sale concern. With complete facilities, strong R&D ability and professional after-sale service, GSM continuously supplying complete deep hole drilling solution and earned high reputation among clients of domestic and overseas.
Years of development, GSM developed three-coordinate deep hole drilling machines, BTA drilling machines and Ejector drilling machines besides gun drilling machines. The machine drilling hole diameter is developed from 0.8 mm to 150 mm and can be used for drilling deep hole of axial workpiece, box-type workpiece and special workpiece, etc. GSM deep hole drilling machine are widely used in promoting manufacturing ability of various industries such as automotive, coal machinery, hydraulic, medical device, mining machinery, mold, etc. Besides manufacturing, GSM also provides sub-contract service with its own machines.
GSM mission is to benefit clients by high-class deep hole drilling technology and service. GSM goal is to be leading deep hole drilling technology supplier of the world by constant innovation of deep hole drilling technology.
