How much does the Palmary OIG-200D cost?
Price estimate
We do not have a price for the Palmary OIG-200D 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 Palmary OIG-200D is a CNC internal grinder with two internal wheel spindles and a third linear axis, Y, to carry the second one. It grinds bores up to Ø150 mm (5.9 in) in parts up to 200 mm (7.9 in) long.
Two spindles let one chucking do the work of two machines or two setups: rough and finish with different wheels, a large bore and a small one, or a bore and a face with a wheel suited to each. Palmary says the model can grind an internal hole, an end face and an outer diameter at one setting. In the product photograph the machine is shown with a robot loading cell.
X, Z and Y each have 480 mm (18.9 in) of travel, a 10 m/min (394 ipm) rapid rate and a 1.8 kW (2.4 hp) servo motor. Both wheel spindles are the Ø90 mm (3.5 in) type with a 10,000 to 50,000 rpm range, and the standard accessories include two of them.
The workhead swivels +7° to -8°, as on the single-spindle OIG-200, with a 0.75 kW (1.0 hp) motor. One figure is lower than on that machine: the work spindle load is 35 kg (77 lb) here. The extra axis and spindle add a tonne, taking the weight to 5,700 kg (12,566 lb). A FANUC CNC controller, fully enclosed splash guard and X-axis linear scale are standard.
