How much does the Palmary OCA-3295H cost?
Price estimate
We do not have a price for the Palmary OCA-3295H 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 OCA-3295H has 950 mm (37.4 in) between centers, the longest of the three wide-wheel CNC plunge cylindrical grinders in the OCA-H group. Swing is Ø320 mm (12.6 in) and maximum grinding diameter Ø300 mm (11.8 in).
What a buyer gets for the length is a machine able to plunge-grind seats near both ends of a shaft almost a metre long. What stays fixed is the 150 kg (331 lb) load between centers and the 35 kg (77 lb) limit on the work spindle alone. A long part under a wide plunge cut wants support, and Palmary's options include a 2-point steady rest set and an adjustable 3-point steady rest.
The table stroke is 1,200 mm (47.2 in), equal to that of the OCA-3265H, and the table swivels 0° to 10°. The workhead covers -30° to +90° and 0 to 300 rpm with an 0.8 kW (1.1 hp) AC servo motor. Its low power is a reminder that in plunge grinding the work turns slowly against a wheel doing the cutting.
That wheel is Ø610 mm, listed 80 mm wide with 150 mm as an option, on an 11 kW (14.8 hp) motor. Slides are hydro-static throughout, according to Palmary. The enlarged guard is meant to house an automatic loader. Standard items include a FANUC CNC controller and a linear scale for X. Palmary prints no weight for this model; total power is 24 kVA and the coolant tank holds 230 L (60.8 gal).
