Price estimate
We do not have a price for the Palmary OCD-65400 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-65400 is the largest cylindrical grinder in Palmary's catalogue by envelope: Ø650 mm (25.6 in) of swing and 4,000 mm (157.5 in) between centers. It is a heavy duty CNC machine with a table stroke of 4,620 mm (181.9 in).
Envelope and load do not scale together here, and a buyer should be clear about it. The part may be up to Ø620 mm (24.4 in) across and four metres long, but it may weigh no more than 800 kg (1,764 lb) between centers. That suits tubes, sleeved and rubber-covered rolls and fabricated rollers. It does not suit solid forged rolls of that size.
Palmary gives the weight as 18,000 kg (39,683 lb) and the supply as 33 kVA. The same weight is printed for the OCD-45400, which has a smaller swing, so treat it as a guide and get the shipping weight confirmed. No floor dimensions are stated.
The working parts are those of the OCD-65 series. A Ø610 mm wheel, 50 to 125 mm wide, runs at 33 m/s (6,496 ft/min) on an 11 kW (14.8 hp) motor in hydro-static bearings. The work spindle turns at 0 to 210 rpm on a 5.5 kW (7.4 hp) servo motor, and its head is fixed. Table swivel is 0° to 3°. X and Z resolve 0.001 mm, with a linear scale on X. Control is by FANUC CNC, and gap control, a touch probe and an in-process gauge can be added.

Strengths & Limitations
Strengths
- Largest envelope in Palmary's cylindrical range: Ø650 mm (25.6 in) swing, 4,000 mm (157.5 in) between centers
- 4,620 mm (181.9 in) table stroke
- 5.5 kW (7.4 hp) servo workhead with speeds from 0 to 210 rpm
- Gap control, touch probe gauge and in-process gauge available as options
Limitations
- 800 kg (1,764 lb) load limit is small against the envelope
- Table swivel 0° to 3°; work spindle head fixed
- Listed weight of 18,000 kg (39,683 lb) is the same as the smaller-swing OCD-45400, so confirm it
- Semi-enclosed splash guard on a machine with a 230 L (60.8 gal) coolant system

Frequently Asked Questions
01
Up to Ø620 mm (24.4 in) in diameter and 4,000 mm (157.5 in) between centers, with Ø650 mm (25.6 in) of swing over the table. Weight between centers is limited to 800 kg (1,764 lb).
02
Only small ones. The load between centers is 800 kg (1,764 lb), far below the weight of a solid steel body filling the Ø620 mm (24.4 in) by 4,000 mm (157.5 in) envelope. The machine fits hollow, sleeved or covered rolls of that size.
03
The table gives a net weight of 18,000 kg (39,683 lb), identical to the figure printed for the OCD-45400. Total power is 33 kVA. Coolant capacity is 230 L (60.8 gal) and the three oil tanks hold 31 L (8.2 gal) each.
04
A FANUC CNC controller and a linear scale for the X axis are standard accessories. The minimum setting unit on X and the minimum input increment on Z are both 0.001 mm. Ballscrews are lubricated automatically from a 0.7 L tank.
