Price estimate
We do not have a price for the Palmary OCD-45400 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-45400 is the longest OCD-45 heavy duty CNC cylindrical grinder: 4,000 mm (157.5 in) between centers, with a table stroke of 4,620 mm (181.9 in). It is the machine Palmary shows in its heavy duty video.
At four metres the proportions of the work change. Swing is Ø450 mm (17.7 in) and maximum grinding diameter Ø420 mm (16.5 in), so the parts are long in relation to their diameter, and the 800 kg (1,764 lb) load rating becomes the practical limit well before the envelope is filled with solid steel. Check part weight first.
A full-length pass of the table at the 10 m/min (394 ipm) rapid rate takes some time, so cycle planning on this model is mostly about minimising table reversals. The wheel can help: Ø510 mm in diameter and up to 125 mm wide, on 11 kW (14.8 hp), it covers a wide band per pass. Table swivel is 0° to 3°.
Installation is the other consideration. The machine weighs 18,000 kg (39,683 lb), needs 30 kVA and carries 230 L (60.8 gal) of coolant plus three 31 L (8.2 gal) oil tanks for wheel spindle lubrication, slide lubrication and hydraulics. Standard equipment follows the series: FANUC CNC controller, hydraulic tailstock, X-axis linear scale, semi-enclosed splash guard and a vibration meter for manual wheel balancing.

Strengths & Limitations
Strengths
- 4,000 mm (157.5 in) between centers, the longest in the OCD-45 series
- 4,620 mm (181.9 in) of table stroke
- Wheel up to 125 mm wide on an 11 kW (14.8 hp) spindle
- Hydraulic tailstock and X-axis linear scale are standard accessories
Limitations
- 800 kg (1,764 lb) between centers is modest for a 4,000 mm (157.5 in) part
- Table swivel of 0° to 3° and a fixed work spindle head
- 18,000 kg (39,683 lb) and a very long footprint; the page gives no floor dimensions
- Rapid traverse of 10 m/min (394 ipm) over a long table stroke
