Price estimate
We do not have a price for the Palmary OCA-3265H 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-3265H is the 650 mm (25.6 in) version of Palmary's wide-wheel CNC plunge cylindrical grinder. It swings Ø320 mm (12.6 in), grinds to Ø300 mm (11.8 in) and carries 150 kg (331 lb) between centers.
A longer plunge grinder is for shafts with more than one wide seat. With 1,200 mm (47.2 in) of table stroke the wheel can plunge at one position, traverse at 10 m/min (394 ipm) and plunge again, all within a single clamping. The table feed is a 1.4 kW (1.9 hp) AC servo and the wheelhead feed 2.5 kW (3.4 hp), with a 0.001 mm minimum setting unit on X.
Palmary's page makes two claims about the grinding end that the table does not repeat. The wheel drive is variable frequency and, Palmary says, can reach a cutting speed of up to 60 m/s; the table's linear velocity row gives 33 m/s (6,496 ft/min). And the wheel spindle is described as taking a wheel up to 125 mm wide, where the table gives 80 mm with 150 mm optional. The motor is 11 kW (14.8 hp).
No weight is printed for this model; the weight row is filled only for the shortest machine in the group. Slides are hydro-static, the tailstock is a taper fine adjustment type, and the control is a FANUC CNC that Palmary describes as conversational. An outside diameter measuring system is offered as an option. Total power is 24 kVA.

Frequently Asked Questions
01
650 mm (25.6 in) between centers, Ø320 mm (12.6 in) swing, Ø300 mm (11.8 in) maximum external grinding diameter. X stroke is 360 mm (14.2 in) and Z stroke 1,200 mm (47.2 in). Load between centers is 150 kg (331 lb).
02
The specification table gives a linear velocity of 33 m/s (6,496 ft/min). Palmary's description says the variable frequency wheel speed control can reach a maximum cutting speed of 60 m/s. Which applies depends on the wheel and guarding supplied, so have it confirmed.
03
Palmary's table does not say. The weight row gives 5,600 kg (12,346 lb) for the OCA-3235H and is blank for this model. Request the weight and floor plan with the quotation; the supply requirement is listed as 24 kVA.
