How much does the Pinnacle B3KCNC cost?
Price estimate
We do not have a price for the Pinnacle B3KCNC 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
The Pinnacle B3KCNC is a CNC bed-type milling machine: the CNC version of Pinnacle's PK-B3K bed mill, with 1,020 mm (40.2 in) of X travel, 460 mm (18.1 in) of Y and 500 mm (19.7 in) of Z. It is the simplest CNC machine in the range and the lightest, at 2,700 kg (5,952 lb).
The table shows its bed-mill origin. It is long and narrow, 1,524 x 305 mm (60.0 x 12.0 in), with a 300 kg (661 lb) load limit, so it suits bars, rails and plates clamped along X more than bulky castings. The spindle nose stands 150 - 660 mm (5.9 - 26.0 in) above it.
A BT40 spindle runs at 8,000 rpm on a 5.5 kW (7.4 hp) motor. Rapid traverse is 10 m/min, a fraction of what Pinnacle's LV vertical machining centers reach, and the tool changer capacity is listed as 16/20. Tools may be 90 mm (3.5 in) in diameter, 250 mm (9.8 in) long and 8 kg (18 lb).
The controller row reads M70. Standard accessories are basic: a cooling pump system, auto lubrication, way chip protectors, a chip tray and a worklight. Nothing on the page mentions a full enclosure. The coolant tank holds 90 L. For toolroom work, one-off parts and training, that is a sensible specification; for production the LV85 class is the next step.
