How much does the Hartford SW-316 cost?
Price estimate
We do not have a price for the Hartford SW-316 that we can stand behind, so we show no number. Configuration, options and installation move the final price a long way: a quote is the reliable figure.
Overview
Seventeen T-slots across a table three metres long: the Hartford SW-316 is a box-guideway double-column machining center for long, fairly narrow work. Its table is 3,000 x 1,450 mm (118.1 x 57.1 in), X travel is 3,100 mm (122.0 in) and Y travel 1,600 mm (63.0 in).
The T-slot row reads 22 x 180 (17) mm. Slots at that spacing make it easy to clamp a row of smaller parts or several vises, so the SW-316 serves batch work on plates and bars as well as single long parts. The table takes 8,000 kg (17,637 lb).
Like the SW-216 it is a pure gear-spindle machine. The #50 gear head runs 6,000 / 8,000 rpm on 15/18.5 kW, with 18.5/22 kW and 22/26 kW optional. Hartford states spindle run-out within 5μm. An arm-type magazine holds 32 tools, or 40, and an S type holds 20.
Z travel is 780 mm, with 1,070 mm given in brackets as the longer stroke. The gibs on X and Y are doubled and lubricated directly through the taper gib, which Hartford says prevents oil from leaking at the contact surface and protects the Turcite-B way lining. An angle head can be fitted for work on the sides of a part.
