Overview

The Palmary OCA-3235H is a CNC plunge cylindrical grinder built on Palmary's heavy OCA frame. It has Ø320 mm (12.6 in) of swing, 350 mm (13.8 in) between centers and grinds to Ø300 mm (11.8 in), with an 11 kW (14.8 hp) wheel motor.

Palmary files it under plunge grinding with a special wider grinding wheel. The table lists the wheel as Ø610 mm in diameter and 80 mm wide, with 150 mm as an option. The descriptive text on the same page speaks of a maximum 125 mm wheel width, so the two do not quite agree; settle the width you need in writing. The text also says the variable frequency wheel drive can reach a cutting speed of up to 60 m/s, although the table's linear velocity row reads 33 m/s (6,496 ft/min).

In layout the H differs from the angular OCA-3235 in three ways that show in the tables. The workhead swivels through the full -30° to +90°. The wheelhead feed is a 2.5 kW (3.4 hp) AC servo. And an internal grinding spindle of 0.75 kW (1.0 hp) is listed as an option.

All slides are hydro-static according to Palmary, and the splash guard is enlarged so that an automatic loading and unloading device can sit inside it. Travels are 360 mm (14.2 in) on X and 750 mm (29.5 in) on Z. A FANUC CNC controller is standard. Weight is 5,600 kg (12,346 lb), power 24 kVA.

Frequently Asked Questions

01 What is the Palmary OCA-3235H designed to do?

Plunge grinding with a wide wheel. Palmary describes a structure strengthened along the lines of its heavy duty cylindrical grinders and an enlarged hydrostatic wheel spindle. Capacity is Ø300 mm (11.8 in) by 350 mm (13.8 in) between centers and 150 kg (331 lb).

02 How wide a wheel can the OCA-3235H carry?

The specification table gives Ø610 mm by 80 mm, with 150 mm as an option, on a 203.2 mm bore. Palmary's text on the same page says the spindle can carry a wheel of up to 125 mm in width. Confirm the figure for the wheel you intend to run.

03 Can the OCA-3235H be loaded automatically?

Palmary says the enlarged splash guard allows an automatic loading and unloading device to be fitted inside, which shortens cycle time and saves space. The loader itself is not in the listed accessories for this page, so it is quoted separately.

04 How does the OCA-3235H differ from the OCA-3235H200?

Wheel width. The OCA-3235H200 is listed with a Ø610 mm wheel 200 mm wide and weighs 5,700 kg (12,566 lb). The OCA-3235H is listed with an 80 mm wheel, 150 mm optional, and weighs 5,600 kg (12,346 lb). Travels and motors are the same.
