Introduction
The Tool Torque Testing Machine is mainly designed for torque testing of tools by tool manufacturers, testing laboratories, and research institutions. With appropriate fixtures, it can perform mechanical performance testing on a wide range of tools, finished products, semi-finished products, and workpieces.
Applications
The machine can be equipped with different fixtures for testing:
Wrenches
Ratchet wrenches
Pipe wrenches
Sockets
Screwdrivers
Other hand tools
Finished and semi-finished tool products
Metal raw materials and workpieces
The computer-controlled system can automatically complete cyclic testing of various tools and metal materials. Individual parameters can also be tested separately according to specific requirements.
