Price estimate
We do not have a price for the Palmary OCD-45300 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
Three metres between centers is the headline of the Palmary OCD-45300, a heavy duty CNC cylindrical grinder for long rolls and shafts. The exact figure is 3,000 mm (118.1 in), with Ø450 mm (17.7 in) of swing and Ø420 mm (16.5 in) of grinding diameter.
On a bed this long the slideway is the machine. Palmary describes enlarged stride and rail width on the longitudinal and traverse tables, precision scraping on horizontal and vertical faces, and a hydrostatic structure for light, steady table movement. The table stroke is 3,520 mm (138.6 in) and the servo motor behind it is rated 4.4 kW (5.9 hp).
The trade-off of length is taper range. The table swivels only 0° to 3°, and because the work spindle head is fixed, that is all the angular adjustment there is. Parts for this machine are parallel, or formed by the wheel: Palmary notes the external wheel can grind a formed outside diameter in one pass, and wheel width may go up to 125 mm on the 11 kW (14.8 hp) spindle.
Load capacity is 800 kg (1,764 lb) between No. 5 Morse taper centers, the same as on the shortest model of the series, so very long parts must still be watched for weight. The hydraulic tailstock is standard, as are the FANUC CNC controller and an X-axis linear scale. Machine weight is 16,000 kg (35,273 lb).
