Ecoca VL-800

The middle model of Ecoca's linear-guide VMC range, the VL-800, has 800 mm (31.5 in) of X travel over an 860 x 450 mm (33.9 x 17.7 in) table. Y travel is 450 mm (17.7 in), matching the table depth, and Z is 480 mm (18.9 in). The table is rated for 500 kg (1,102 lb).

Those proportions make it a long, narrow machine. The X stroke is close to twice the Y stroke, which is the right shape for three vises in a row, for bar-shaped parts such as rails and manifolds, or for a rotary axis mounted at one end with a tailstock at the other. Deep plates and square fixtures are better placed on the VL-1000, whose table is 510 mm (20.1 in) deep.

The cutting end is shared with the VL-600. A belt-driven BT-40 spindle reaches 8,000 rpm with an 11/15 kW (14.8/20.1 hp) motor, the armless changer carries 16 tools, and rapid traverse is 24/24/24 m/min (945/945/945 ipm). What the larger frame adds is weight, 4,000 kg (8,818 lb), which along with the heavier table rating says something about how much casting sits under the longer X axis.

Ecoca's notes on the series are brief: heavy-duty linear guideways, a high-rigidity structure, and large precision ball screws on the 3 axes, preloaded and pre-tensioned. Standard accessories listed on the page include a guideway cover, chip enclosure, cutting air blast, auto lube system, coolant system and leveling blocks. The page does not name a CNC control or give tool change times.
