UM-320B
Description
1. This lathe is suitable for mechanical processing in various industries. It can be used for rough and finish machining of internal and external cylindrical surfaces, internal and external conical surfaces, end faces, grooving, etc.
2. The worktable spindle uses high-precision double-row short cylindrical roller bearings with adjustable radial clearance for centering. A constant-flow hydrostatic guideway is adopted axially, endowing the worktable with the characteristics of high rotation accuracy, large load-carrying capacity, and small thermal deformation.
3. The main parts such as the base, worktable, bed, and crossbeam are made of high-strength, wear-resistant gray cast iron, which undergoes tempering treatment to eliminate internal stress and prevent deformation.
4. There are two types of vertical tool rests: square ram and manual five-angle tool post. The side tool rest is equipped with a four-square tool post, and both tool rests adopt hydraulic balancing.
5. The spindle drive of the lathe is powered by an AC motor, which, through a 16-speed spindle speed change mechanism, achieves the speed range of the worktable.
6. According to user requirements, accessories such as digital readout (DRO), electric grinding head, and taper turning attachments can be added. All sliding parts are automatically lubricated.
7. The guideway surfaces of the column and crossbeam undergo high-frequency quenching, with a quenching hardness of HRC 48-55 degrees.
