Q: How much does the Palmary OCD-3280P cost?

The price estimate for the Palmary OCD-3280P is uncertain: we have no price for it that we can cite and no estimate we can stand behind, so we give no figure. Configuration, tooling, automation and installation move the final price substantially.

Overview

With 800 mm (31.5 in) between centers the Palmary OCD-3280P is the long model of the Ø320 mm (12.6 in) swing plunge grinders with angular wheelhead. It is a CNC machine for stepped shafts with several ground diameters and shoulders along their length.

Multi-diameter shafts are where plunge grinding and a long Z axis work together. The table strokes 1,308 mm (51.5 in), so the wheel can be indexed from seat to seat along an 800 mm part and still reach the tailstock-mounted diamond holder to dress. Rapid traverse is 10 m/min (394 ipm).

Two details change from the shorter P models. The workhead motor is 1.5 kW (2.0 hp), up from 1.0 kW on the OCD-3240P, and the table swivel becomes two-sided, -3° to +8°, which is useful for trimming out taper on a longer part. The wheel is unchanged: Ø455 to 510 mm, 50 to 80 mm wide, 5.5 kW (7.4 hp), in hybrid hydro-static bearings.

Maximum grinding diameter is Ø300 mm (11.8 in) and the centers carry 150 kg (331 lb). At 4,300 kg (9,480 lb) the machine weighs only slightly more than the OCD-3240P. A FANUC CNC controller, micro adjustment tailstock, linear scale for X and a fully enclosed splash guard are standard; steady rests, a hydraulic tailstock and in-process gauging are options.
