Ecoca SL-8MC

Ecoca lists the SL-8MC beside the SL-8 as the 12-station version of its small linear-guide lathe. It has the 8 in (203 mm) chuck, 4,500 rpm spindle and 11/15 kW (14.8/20.1 hp) motor of the base model, with a different turret and a slightly tighter swing over the cross slide.

A word of caution about the suffix. On the MT pages, each MC column comes with a milling speed row. The SL table has no such row at all. Three things change between the SL-8 column and this one: tool stations go from 10 to 12, swing over the cross slide goes from 350 mm (13.8 in) to 340 mm (13.4 in), and weight goes from 3,350 kg (7,385 lb) to 3,450 kg (7,606 lb). The accessories note about optional living tool holders is the only other hint of driven tooling. Before quoting milled features to a customer, get the driven-tool speed and power from Ecoca in writing.

The turning envelope is not reduced, which is unusual. Maximum turning diameter stays at 320 mm (12.6 in) and turning length at 480 mm (18.9 in). On several of the box-way MT machines the MC column shows a smaller turning diameter than the two-axis one, so a buyer comparing the two families should note the difference.

Underneath is the SL platform as Ecoca describes it: a 30 degree slant design, linear guideways on both axes, and FANUC β series spindle and axial servo motors. The machine suits quick, light-to-medium cutting. If the driven tools check out, it becomes a compact way to finish small turned parts with cross holes or flats in one chucking.
