Price estimate
We do not have a price for the Palmary OIG-200L50 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-200L50 is the long-bed CNC internal grinder of the OIG-200 family, accepting workpieces up to 500 mm (19.7 in) in length. The bore limit is Ø150 mm (5.9 in) and the chuck limit Ø200 mm (7.9 in), as on the shorter models.
Half a metre of part needs a long Z stroke to get the wheel in and back out to the dresser. The table gives 710 mm (28.0 in), and the Z axis motor is raised to 4.4 kW (5.9 hp) to move the heavier table; the other OIG-200 models use 1.8 kW there. X travel is 480 mm (18.9 in). Rapid traverse on Z is 10 m/min (394 ipm).
Deep-bore grinding is a stiffness problem more than a power problem. The longer the quill, the lighter the cut it can take without deflecting, and no machine specification removes that. What the OIG-200L50 offers toward it is an optional 2.25 kW wheel motor, a wheel spindle speed range of 10,000 to 50,000 rpm so that wheel speed can be matched to quill and wheel size, slides on roller type linear guideways, and an optical scale on the feed axis.
The workhead has a 2.25 kW (3.0 hp) motor and swivels +1° to -1° for taper correction. It carries 50 kg (110 lb). Standard accessories include a FANUC CNC controller, enclosure, diamond dresser and X-axis linear scale. At 5,700 kg (12,566 lb) it is the heaviest single-spindle OIG.

Frequently Asked Questions
01
Up to 500 mm (19.7 in) of workpiece length, with bores up to Ø150 mm (5.9 in). The Z axis travels 710 mm (28.0 in) and the X axis 480 mm (18.9 in).
02
The maximum load of the work spindle, tool holder included, is 50 kg (110 lb). That is the same figure as for the OIG-200 and OIG-200L35, so a long part has to be light, such as a sleeve or thin-walled cylinder.
03
It has 710 mm (28.0 in) of travel and a 4.4 kW (5.9 hp) motor. The OIG-200L35 has 450 mm (17.7 in) of Z travel with a 1.8 kW (2.4 hp) motor. Minimum setting unit is 0.001 mm on both.
04
A FANUC CNC controller, fully enclosed splash guard, one grinding wheel spindle, linear scale for the X axis, diamond dresser, automatic belt tension adjustment, electric system, coolant tank with pump, work lamp and tools.
