Price estimate
We do not have a price for the Palmary OCA-3235H200 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-3235H200 carries the widest wheel of any Palmary cylindrical grinder: Ø610 mm in diameter and 200 mm across, on a 203.2 mm bore. It is a CNC plunge grinder with Ø320 mm (12.6 in) of swing and 350 mm (13.8 in) between centers.
A 200 mm wheel on a 350 mm center distance tells you how the machine is used. The wheel covers most of the part, so a whole short shaft, or a row of small parts on an arbor, is finished in a single plunge. Palmary's own video shows the machine with a load and unload device, and the large fully enclosed splash guard is described as designed for more interior space.
An 11 kW (14.8 hp) motor drives the wheel at 33 m/s (6,496 ft/min). Spread over 200 mm of contact that is a finishing power level, so stock per plunge has to be kept in proportion. A cantilever crane for wheel changes is supplied as standard, which a wheel of this size needs.
The slides are all hydrostatic, the tailstock is a taper fine adjustment type, and X reads from a linear scale with a 0.001 mm minimum setting unit. Travels are 360 mm (14.2 in) on X and 750 mm (29.5 in) on Z. The standard accessory list names a CNC controller without giving its make. Load between centers is 150 kg (331 lb), weight 5,700 kg (12,566 lb), power 24 kVA.

Strengths & Limitations
Strengths
- Ø610 mm wheel, 200 mm wide, the widest in Palmary's cylindrical range
- Large fully enclosed splash guard designed for more interior space; shown by Palmary with a load and unload device
- Cantilever crane for grinding wheel changes is a standard accessory
- All slides hydrostatic, with a linear scale on X
Limitations
- 11 kW (14.8 hp) spread over a 200 mm wheel limits stock removal per plunge
- Only one length: 350 mm (13.8 in) between centers
- The accessory list does not name the make of the CNC controller
- Shorter option list than the other OCA-H models; no steady rest with three points or chucks listed

Frequently Asked Questions
01
Its wheel width. The table lists a Ø610 mm wheel 200 mm wide, where the OCA-3235H is listed with an 80 mm wheel and 150 mm as an option. Capacity is otherwise the same: Ø300 mm (11.8 in) by 350 mm (13.8 in) between centers.
02
The standard accessory list for this model says only "CNC controller", and Palmary describes it as a conversational controller that is easy to operate. The make is not named on this page, so confirm it with the quotation. An optional gap control and gauges are listed.
03
A wheel balancing stand and arbor, an automatic grinding wheel balancer, cam locked driving dogs, a 2-point steady rest, a touch probe gauge, an automatic in-process gauge, gap control, a magnetic coolant separator, a paper filter and an oil mist collector.
04
Net weight is 5,700 kg (12,566 lb) and total power 24 kVA. The coolant tank holds 230 L (60.8 gal). Wheel spindle lubrication, slide lubrication and hydraulics each have a 31 L (8.2 gal) tank.
