Main Characteristics& Application
?????? Model 57-3C UniversalKnee-type Milling Machine is a minitype machine, used for millingflat, inclined face, vertical surface and slots by employing disccutters, angular cutters, formed cutters and face metal millingcutters. When mounted with the vertical milling attachments, themachine will be able to perform milling operations in variousdirections. When mounted with the rotary table, helix groove andring formed can be milled. With the universal dividing head, themachine will be able to cut spur gear M=3mm, helical gears, bevelgears, etc..
?????? Owing the versatileapplications, the machine is well suited for repair shops and toolrooms for single piece and lot production.
