We do not have a price for the Palmary PCB-4520 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 PCB-4520 is a CNC centerless grinder with a Ø455 mm grinding wheel on a bearing-type spindle, for work from Ø1 to Ø80 mm. It is the PCB-series counterpart of the FCL-18 and uses the same wheel diameter and 205 mm width.

Palmary draws the comparison itself. Against the FCL series it claims a 26% energy saving for this machine, and it attributes precision and rigidity to high-accuracy NN bearings in the grinding wheel spindle. The table adds a faster wheel: 45 m/s (8,858 ft/min), where the FCL-18 runs at 33 m/s.

The slides are different too. Upper and lower slides are listed as square slides driven by ball screw and reducer. Palmary describes the machine as designed for up to 6 axes of CNC control, with servo motors on the driven axes. The grinding wheel spindle is lubricated by oil mist and the regulating wheel spindle by grease.

Grinding power is 15 HP (11 kW), with 20 HP (15 kW) as an option. The regulating wheel is Ø260 mm by 205 mm on a 2 kW (2.7 hp) servo, 10 to 300 rpm. It tilts ±5° and swivels ±0.5°. Dressing is by single point, with a diamond roller dressing device optional. A FANUC CNC controller is standard, and the machine weighs 3,800 kg (8,377 lb), against 2,900 kg (6,393 lb) for the FCL-18.

Frequently Asked Questions

01 What is the grinding range of the Palmary PCB-4520?

Ø1 to Ø80 mm as standard. The grinding wheel is Ø455 x 205 mm on a 228.6 mm bore and the regulating wheel Ø260 x 205 mm on a 101.6 mm bore. Wheel speed is 45 m/s (8,858 ft/min).

02 How does the PCB-4520 differ from the FCL-18?

The FCL-18 is an alloy bearing spindle machine running at 33 m/s (6,496 ft/min) and weighing 2,900 kg (6,393 lb). The PCB-4520 has a rolling bearing spindle at 45 m/s (8,858 ft/min), ball screw slides and weighs 3,800 kg (8,377 lb).

03 What motors does the PCB-4520 have?

The grinding wheel motor is 15 HP (11 kW), with a 20 HP (15 kW) motor as an option. The regulating wheel is driven by a 2 kW (2.7 hp) servo motor and runs from 10 to 300 rpm.

04 How are the spindles of the PCB-4520 lubricated?

The grinding wheel spindle uses oil mist lubrication and the regulating wheel spindle oil grease. The slides have an automatic lubricator. Tank capacities are 1.0 L for the grinding wheel spindle lubrication system and 4.0 L for the table slides.
