Ecoca SL-10

The Ecoca SL-10 fits a 10 in (254 mm) chuck to the SL linear-guide platform. Its spindle runs to 4,200 rpm with an 11/15 kW (14.8/20.1 hp) motor, the turning diameter is 320 mm (12.6 in), and the turning length is 460 mm (18.1 in).

Notice how little the frame changes from the SL-8. The swing over the bed is still 420 mm (16.5 in), the turning diameter is the same, and the motor is the same. The larger chuck takes a little length, 460 mm (18.1 in) where the SL-8 has 480 mm (18.9 in), and adds weight, 3,450 kg (7,606 lb) in total. What it buys is a bigger grip on the part and, on most chucks of this size, a larger through-hole, though Ecoca's table does not print a spindle bore or bar capacity for either model.

So who should take the SL-10? A shop whose parts are chucked on diameters above what smaller jaws hold comfortably, or whose bar stock is too large for the smaller spindle. If neither applies, the SL-8 is faster at the top end.

Ecoca describes three features of the series. The slant design is 30 degree, for turning stability and easy chip removal. Both axes ride on linear guideways. And the spindle and axis servo motors are FANUC β series. With 10 stations on the turret and a hydraulic tailstock in the standard accessories, the SL-10 is a straightforward two-axis production lathe for medium-duty work.
