Price estimate
We do not have a price for the Palmary OCD-3260CAM 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-3260CAM extends Palmary's CNC cam cylindrical grinder to 600 mm (23.6 in) between centers. Swing is Ø320 mm (12.6 in), grinding diameter up to Ø300 mm (11.8 in) and load between centers 150 kg (331 lb).
At this length the machine moves from single cams toward camshafts and long eccentric shafts with several lobes. The table stroke increases to 826 mm (32.5 in), against 586 mm (23.1 in) on the OCD-3240CAM, and the machine weight to 4,250 kg (9,369 lb). Table swivel remains 0° to 12°.
Lobes along a shaft are ground one after another, so the Z axis is used for positioning and the work is done by X and C together. Z moves at 4 m/min (157 ipm) on a 3.6 kW (4.8 hp) servo. The C axis is the 5.2 kW (7.0 hp) work spindle, which Palmary describes as carrying a precision angle decoder for high resolution of angle control, and both X and C have linear scales as standard.
A long, lobed shaft flexes under the wheel. The wheel is narrow, 50 mm on a Ø355 mm diameter, which keeps grinding forces down, and a 2-point and a 3-point steady rest are on the option list. The optional CBN wheel is narrower still at 16 mm. Lubrication uses a 60 L (15.9 gal) tank and coolant a 100 L (26.4 gal) tank. The standard controller is by NUM.

Frequently Asked Questions
01
Up to 600 mm (23.6 in) between centers, with a table stroke of 826 mm (32.5 in). Maximum external grinding diameter is Ø300 mm (11.8 in) and the load limit between centers is 150 kg (331 lb).
02
The standard accessories include a linear scale for the X and C axes. Palmary also describes a closed loop linear scale on the linear-motor infeed axis and a precision angle decoder on the work spindle.
03
Optional equipment includes a magnetic coolant separator rated 160 L/min, a paper filter rated 160 L/min with a 260 L tank and a hydrocyclone coolant separator. The standard coolant tank holds 100 L (26.4 gal).
04
Yes: the OCD-4260CAM has the same 600 mm (23.6 in) between centers and 826 mm (32.5 in) table stroke with Ø420 mm (16.5 in) of swing and Ø400 mm (15.7 in) grinding diameter, and weighs 5,300 kg (11,684 lb).
