Conventional heavy duty lathe is horizontal lathe. Generally speaking, manual heavy duty lathe has three rectangular guide rails, which adapt to cut different spindles, cylinder and disc, as well as external circle,end face,grooving, and various threads, ferrous metal and nonferrous metal. The bearing capacity of Metal processing normal lathe vary from 16t to 63t.
Heavy duty lathe has a high rigidity lathe bed: the guide rials employ medium-frequency quenching craft, anti-slip measure, which avoid the low speed slip occurring.
Besides spindle box employs symmetric structure, keeping thermal deformation in balance, avoiding spindle center removing. To decrease thermal deformation, spindle box adopts oil bath circulatory lubrication.
What’s more, spindle front end adopts double direction angular contact thrust ball bearing with three supporting structures,which enhances precision, increase rigidity. And the wheel gears inside spindle box assure correct transmission, low noise after quenching and cutting crafts.
