Since1958, Begin...

Xi’an Machine Tool Factory was established in 1958. From beginning, it was specialized in metal cutting. 

Mainly R&D and manufacture lathe machine, milling machine, boring machine,drilling machine, etc.

1978, An Expert...

Pointed by the former National Machinery Industry Ministry of China, the factory began to be a deep hole drilling machine manufacturer in 1978.

During that time, became the only expert manufacture of China and manufactured the first deep hole drilling machine (mainly for drilling diameter ≤Φ30mm).

Since then, the factry had been distinguished as a deep hole drilling machine manufacturer from other machine tool manufacturers of China.

2004, A Leading Drilling Machine Manufacturer...

Because of development of Chinese economy, Xi’an Machine Tool Factory was re-organized. As a result, Shaanxi Golden Stone Machinery Manufacturing Co.,Ltd. (GSM for short) was established as a private enterprise in 2004. 

Main team member of GSM are from the factory. That is, GSM has accumulated the factory’s technical experience and data of more than 30 years. GSM is now still a leading deep hole drilling machine manufacturer of China.

GSM is certified as National High-tech Enterprise and pointed as Metal Material Deep Hole Drilling Technology and Application Engineering Laboratory. Besides, all of GSM’s machines are CE cetificated. All manufacturing is under ISO and Industrial standard. Further more, GSM has obtained more than 20 types of national patent.
