The ALT series h type press machine is closed type double-point circulating thin oil lubrication. The ultra-long eight-sided guide rails can maintain good precision under a little eccentric load due to the two force points and large space. The crankshaft and the slider device are connected by a double-link transmission device; the double-link transmission device comprises two sets of synchronous connecting rods provided on the crankshaft. The synchronous connecting rod is connected with an adjusting screw sleeve which has fixed connection with the slider device.
