<p>The machine drills or cuts plate and/or profiled material, and is portable, with a drilling or cutting head. After fitting and clamping to the material, the head can be moved in two directions and locked by a clamping mechanism, the movements being measured. The holes are drilled by trepanning. When clamped to the material, the head can first be moved on a slide in the transverse direction for a measured amount and then clamped. After release of the clamp engaging with the material, measured movement is then possible in the other direction.</p> |
