CM-99 Spot Scarfing Machine

Print Print

The CM-99 Spot Scarfing machine is a rugged, overhead type machine, with individually selectable scarfing units. The units are mounted on three separate carriages; an edge unit carriage, and two top unit carriages, which can be mechanically latched together for band pass scarfing. For spot scarfing passes on the top surface, the two carriages are unlatched and are indexed laterally across the slab. The machine will scarf cold, warm, or hot slabs from ambient to hot rolling temperature (21°C/70°F to 1092°C/2000°F). The CM-99 has all the capabilities of the CM-88 in a stationary machine.

For high production, it is desirable to employ two machines in any one of several possible arrangements. For lower tonnages, a single machine may be used. In either case, slabs must be turned over between passes if all four sides are to be scarfed.

Three sizes of the type CM-99 spot scarfing machine are available. The capacity ranges are shown in the following table:
