How much does the Palmary OIG-200L35 cost?
Price estimate
We do not have a price for the Palmary OIG-200L35 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 OIG-200L35 is the 350 mm (13.8 in) workpiece-length version of the OIG-200 CNC internal grinder. Bore capacity stays at Ø150 mm (5.9 in) and the chuck at Ø200 mm (7.9 in); what changes is how long a part the machine will hold and turn.
A longer part overhangs the chuck further, and the table shows the workhead rebuilt for it. Its motor is 2.25 kW (3.0 hp), three times that of the short model. Its swivel, on the other hand, is cut to +1° to -1°: enough to correct taper in a long bore, not enough to set a taper angle. Shops that grind tapered bores by swivelling the workhead should stay with the OIG-200.
The Z axis travels 450 mm (17.7 in) and the X axis 480 mm (18.9 in), with 1.8 kW (2.4 hp) servos on both and a 0.001 mm minimum setting unit. Slides run on roller type linear guideways, and Palmary notes an optical scale on the feed axis.
The wheel spindle is the family's Ø90 mm (3.5 in) unit at 10,000 to 50,000 rpm. For this model the table adds an optional 2.25 kW wheel motor beside the standard 1.5 kW, a sensible upgrade when deep bores call for long quills and steadier power. FANUC control, a fully enclosed splash guard and a diamond dresser are standard. The machine weighs 5,000 kg (11,023 lb).

Frequently Asked Questions
01
350 mm (13.8 in). The maximum internal grinding diameter is Ø150 mm (5.9 in) and the maximum chuck outer diameter Ø200 mm (7.9 in). Z axis travel is 450 mm (17.7 in).
02
Only slight ones by workhead swivel, which is +1° to -1° on this model. Steeper tapers would have to be generated by the CNC moving X and Z together. The shorter OIG-200 swivels +7° to -8°.
03
Grinding wheel 1.5 kW with 2.25 kW as an option; workhead 2.25 kW (3.0 hp); X and Z axis infeed tables 1.8 kW (2.4 hp) each; hydraulic pump 0.75 kW (1.0 hp); coolant pump 0.09 kW.
04
Yes. The OIG-200L50 takes workpieces up to 500 mm (19.7 in) long, with 710 mm (28.0 in) of Z travel and a 4.4 kW (5.9 hp) Z axis motor, and weighs 5,700 kg (12,566 lb).
