Price estimate
We do not have a price for the Palmary OCD-42100 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-42100 is the 1,000 mm (39.4 in) model of the OCD-42 CNC cylindrical grinders and sits in the middle of five bed lengths. It swings Ø420 mm (16.5 in) over the table and grinds diameters up to Ø400 mm (15.7 in).
A metre between centers with this swing covers a wide spread of work: transmission shafts, small rolls, hydraulic rods, machine spindles. The limit that decides what actually fits is weight. Palmary rates the centers at 150 kg (331 lb), so a solid steel roll near full diameter is out of range and belongs on the heavy duty OCD-45 series.
The table travels 1,315 mm (51.8 in) and swivels from -3° to +8°. That two-sided swivel first appears at this length in the 42 family; the OCD-4240 and OCD-4260 swivel in one direction only. The wheelhead has 260 mm (10.2 in) of stroke with a linear scale, and both axes rapid at 10 m/min (394 ipm). A 1.5 kW (2.0 hp) servo motor drives the work spindle at 10 to 300 rpm.
Grinding power is 5.5 kW (7.4 hp) on a Ø405 mm wheel that may be 50 to 75 mm wide. The wheel spindle runs in hybrid hydro-static bearings and the tailstock sits in an automatic oil bath. FANUC control and full enclosure are standard. Net weight is 4,500 kg (9,921 lb), total power 18 kVA.

Strengths & Limitations
Strengths
- 1,000 mm (39.4 in) between centers under a Ø420 mm (16.5 in) swing
- Two-sided table swivel, -3° to +8°
- 1,315 mm (51.8 in) of table stroke for traverse grinding and dressing run-off
- Tailstock with automatic oil bath lubrication and an oil level gauge
Limitations
- 150 kg (331 lb) between centers limits how much of the Ø400 mm (15.7 in) capacity can be used on solid parts
- Workhead motor is 1.5 kW (2.0 hp); the 2 kW motor comes only with the OCD-42150 and OCD-42200
- Wheel width tops out at 75 mm, so wide plunge cuts take several passes
- Hydraulic tailstock and steady rests are options

Frequently Asked Questions
01
External diameters up to Ø400 mm (15.7 in) on parts up to 1,000 mm (39.4 in) between centers, weighing no more than 150 kg (331 lb). Palmary says the work spindle head suits external and face grinding, and internal diameter grinding with the optional attachment.
02
From -3° to +8°. The shorter OCD-4240 and OCD-4260 swivel 0° to 12° and 0° to 10°. The work spindle head swivels separately, from -30° to +90°, and the tailstock offers ±0.03 mm of fine adjustment for removing taper.
03
Wheel spindle 5.5 kW (7.4 hp), workhead 1.5 kW (2.0 hp) AC servo, wheelhead feed 1.2 kW (1.6 hp) AC servo and table feed 1.8 kW (2.4 hp) AC servo. The optional internal grinding spindle is 0.75 kW (1.0 hp). Total power is 18 kVA.
04
Same length and travels, more swing. The OCD-32100 swings Ø320 mm (12.6 in) and weighs 4,300 kg (9,480 lb). The OCD-42100 swings Ø420 mm (16.5 in) and weighs 4,500 kg (9,921 lb). Both carry 150 kg (331 lb) between No. 4 Morse taper centers.
