We do not have a price for the Palmary OCA-3235 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 OCA-3235 is a CNC angular cylindrical grinder: the wheelhead approaches the work at an angle, so a single infeed grinds a diameter and the shoulder next to it. It has Ø320 mm (12.6 in) of swing, 350 mm (13.8 in) between centers and a maximum grinding diameter of Ø300 mm (11.8 in).

Palmary calls this a heavy duty type, and the wheel shows why. It is Ø610 mm in diameter and 150 mm wide on a 203.2 mm bore, driven by an 11 kW (14.8 hp) motor. That is twice the wheel motor power of the standard OCD-3240 and a wheel twice as wide. A cantilever crane for changing it and a grinding wheel inverter are in the standard accessories.

A wheel 150 mm wide is normally dressed to a stepped profile, and the control is set up for that. Palmary states that X and Z move simultaneously to dress the wheel to a specific shape for multiple-step grinding. The wheel slide runs on hydro-static ways with its own hydraulic and lubrication system.

The wheelhead strokes 360 mm (14.2 in) and the table 750 mm (29.5 in), both at 10 m/min (394 ipm). The table swivels -1° to 10°, the workhead 0° to +90°. Load between centers is 150 kg (331 lb). Standard equipment includes a FANUC CNC controller, a taper fine adjustment tailstock and a linear scale on X. The machine weighs 5,600 kg (12,346 lb).

Strengths & Limitations

Strengths

Ø610 mm wheel, 150 mm wide, on an 11 kW (14.8 hp) motor
Simultaneous X and Z movement dresses the wheel to a stepped shape for multiple-step grinding, as Palmary states
Hydro-static slide ways on the angular wheel seat with an independent hydraulic and lubrication system
Cantilever crane for wheel changes and a grinding wheel inverter are standard accessories
Table swivel of -1° to 10°, the widest of the three OCA lengths

Limitations

150 kg (331 lb) between centers despite a 5,600 kg (12,346 lb) machine
350 mm (13.8 in) between centers
Workhead swivels only from 0° to +90°, and the 0.37 kW (0.5 hp) workhead motor is small
The page does not state the wheelhead angle

Best For

Short shafts with several diameters and shoulders ground in one plunge High-volume automotive-type shafts up to 350 mm (13.8 in) Multi-step grinding with a profiled wheel up to 150 mm wide Parts up to Ø300 mm (11.8 in) and 150 kg (331 lb)

Frequently Asked Questions

01 What is an angular cylindrical grinder like the Palmary OCA-3235 used for?

Grinding diameters and adjoining faces together. Palmary lists the OCA-3235 in its angular grinding series with angular wheelhead and says the work spindle head is built for external and face grinding. Capacity is Ø300 mm (11.8 in) by 350 mm (13.8 in) between centers.

02 How big is the grinding wheel on the OCA-3235?

Ø610 mm outside diameter, 150 mm wide, with a 203.2 mm bore. It runs at 33 m/s (6,496 ft/min) on an 11 kW (14.8 hp) motor in hydro-static bearings. A flange extractor and a cantilever crane for wheel changes come as standard.

03 How is the wheel dressed on the OCA-3235?

With a fixed-type diamond tool holder, supplied as standard. Palmary states that simultaneous movement of the X and Z axes can dress the wheel to a specific shape for multiple-step grinding. A gap control and an automatic wheel balancer are optional.

04 What longer versions of the OCA-3235 exist?

The OCA-3265 has 650 mm (25.6 in) between centers and the OCA-3295 has 950 mm (37.4 in); both have a 1,200 mm (47.2 in) table stroke. The OCA-3235 has 350 mm (13.8 in) between centers and a 750 mm (29.5 in) table stroke.
