Price estimate
We do not have a price for the Palmary OCD-3220P 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 OCD-3220P is a CNC plunge cylindrical grinder with an angular wheelhead, Ø320 mm (12.6 in) of swing and a short 200 mm (7.9 in) between centers. Parts up to Ø300 mm (11.8 in) and 150 kg (331 lb) fit, which on a 200 mm length means discs, gears on arbors, flanged bushes and short stub shafts.
Its odd-looking proportion is the table stroke: 818 mm (32.2 in), four times the center distance. The OCD-3240P has exactly the same stroke, so the two share a bed and differ in where the workhead and tailstock sit. For the buyer that means the short model gives up nothing in wheel access or dressing room.
The wheel is the point of the P series. It may be Ø455 to 510 mm in diameter and 50 to 80 mm wide, noticeably bigger than the Ø405 mm wheel of the standard OCD-3240, and it is driven by a 5.5 kW (7.4 hp) motor at 33 m/s (6,496 ft/min). The wheelhead strokes 260 mm (10.2 in) and reads from a linear scale.
The workhead swivels from -30° to +90°, turns at 10 to 300 rpm on a 1.0 kW (1.3 hp) motor and holds 35 kg (77 lb) without the tailstock. The table swivels 0° to 12°. Standard accessories include the FANUC CNC controller and a fully enclosed splash guard. Weight is 3,400 kg (7,496 lb) and power 18 kVA.

Frequently Asked Questions
01
External diameters up to Ø300 mm (11.8 in) on parts up to 200 mm (7.9 in) between centers and 150 kg (331 lb). Palmary places it in its plunge grinding series with angular wheelhead, a layout used to grind a diameter and its shoulder in one infeed.
02
The table gives 818 mm (32.2 in) for this model and the same 818 mm for the OCD-3240P, which has 400 mm (15.7 in) between centers. The page does not explain it; the identical figure suggests a shared bed, with the extra stroke available for dressing and loading clearance.
03
Ø455 to 510 mm outside diameter, 50 to 80 mm wide, on a 127 mm bore. The standard OCD-3240 uses a Ø405 mm wheel 50 to 75 mm wide. Peripheral speed is 33 m/s (6,496 ft/min) and the wheel motor is 5.5 kW (7.4 hp).
04
Palmary lists a touch probe gauge and an automatic in-process gauge as optional accessories, together with an automatic grinding wheel balancer. A linear scale for the X axis is standard, and the X axis minimum setting unit is 0.001 mm.
