Shanghai Instrument Machine Tool Factory optimized and restructured with Shanghai Third Machine Tool Factory in 2010.Shanghai Third Machine Tool Factory, formerly known as Asia Railway Group Factory established in 1944, is a manufacturer of external cylindrical grinding machines in China. In 1958, the public-private joint venture Asia Railway Factory merged with multiple enterprises to form Shanghai Third Machine Tool Factory, which is a designated production enterprise for national cylindrical grinders, optical curve grinders, and coordinate boring machines. Since 2000, Shanghai Third Machine Tool Factory has successively integrated and restructured its assets with former subsidiaries of Shanghai Machine Tool Group, including Shanghai Fourth Machine Tool Factory, Shanghai Jiangning Machine Tool Factory, Shanghai Instrument Machine Tool Factory, and Shanghai Machine Tool Factory.

Shanghai Third Machine Tool Factory is a subsidiary of Shanghai Electric (Group) Corporation, a member unit of China Machine Tool Industry Association, a director unit of Shanghai Mold Industry Association, a member unit of the National Standardization Technical Committee for Metal Cutting Machine Tools, and multiple subordinate technical committees. Shanghai Third Machine Tool Factory has passed ISO9001 quality management system certification, safety production level two enterprise certification, and clean production certification.

Shanghai Third Machine Tool Factory has formed two major production bases through integration, restructuring, and relocation, with an annual output of over a thousand metal cutting machine tools and an annual sales value of approximately 200 million yuan.

Shanghai Third Machine Tool Factory has "Shanghai", "Century", "Jiangning", "Three Highs" “SYJ”、 Registered trademarks such as "Beneficial", "Hudong", "H5", etc. Apply for 12 items and authorize 9 items. The main products include four categories of metal cutting machine tools: CNC milling machine machining centers, grinders, horizontal lathes, various gear machine tools, as well as related specialized equipment and production lines.

CNC milling machine machining center products include vertical machining centers, horizontal machining centers, and CNC bed milling machines. The width specifications of the worktable range from 400 millimeters to 1000 millimeters, and can be configured with workpiece measurement systems and tool measurement systems. Horizontal machining centers can be equipped with worktable exchange devices, and the number of machine tool control axes ranges from three to five. Widely used in industries such as molds, weapons, textile machinery, steam turbines, etc., we can provide users with the selection, design, or manufacturing of process equipment and processing tools according to their needs, and offer turnkey services.

Grinding machine products include cylindrical grinding machines, optical curve grinding machines, and spherical grinding machines. The external cylindrical grinder is capable of grinding external circles from 50mm to 200mm, with three precision levels: ordinary, precision, and high-precision, and three control modes: manual, semi-automatic, and CNC. The semi-automatic and CNC models can be equipped with active measuring instruments for external circles and end faces. The 200mm specification series cylindrical grinder has been recommended as a "Shanghai product" for many years, and the same specification cylindrical grinder has always been used domestically.

Optical curve grinder is a precision grinding equipment equipped with a multi degree of freedom grinding wheel holder and an optical projection system. There are two specifications, 170mm and 250mm, with hydraulic single handwheel control and CNC control. Mainly suitable for grinding flat curved profiles or curved rotating parts such as forming tools, forming templates, and supporting templates, widely used in industries such as textile machinery, molds, and weapons. This variety is currently only produced by Shanghai Third Machine Tool Factory in China.

Lathe products include instrument lathes, CNC horizontal lathes, and CNC pipe threading lathes. The specifications of the CNC horizontal lathe range from 200mm to 360mm, with two forms of bed: flat bed and inclined bed. It can be equipped with automatic tool holder or cutting arrangement, and multiple configurations such as automatic chuck and spring chuck are available for selection. According to user needs, loading and unloading robots can be configured to form a small automatic processing production line.

Shanghai Third Machine Tool Factory is willing to serve the national mechanical processing industry with excellent metal cutting machine tool products.
