the stands are mounted on the bed of the machine the line alignment can be easily done due to guide ways arranged on the bed of the machine. Each forming head consists of a fixed housing and sliding type out board housing. The mill stands will be arranged to locate shafts mounted on taper bearings. For the top shafts the bearings are housed in the cartridge type bearing blocks. The bottom shaft bearings are located in the bored machined in the housings. The bottom arbors are fixed in position whereas the top arbors along with cartridge blocks could be raised or lowered in vertical guides machined in housings.
Roll shafts
the roll shafts dia. 60mm will be manufactured from quality steel and will be keyed to locate tooling.
Drive
