Uncertain

We do not have a price for the Palmary PCB-6020-3 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.

Palmary PCB-6020-3 — price

Price estimate: uncertain

We have no price for the Palmary PCB-6020-3 that we can cite and no estimate we can stand behind, so this page shows no number rather than a guess. A quote from Palmary or an authorised dealer is the reliable figure.

What moves the final price

  • Spindle, control and probing options
  • Tool changer capacity and tooling package
  • Automation — pallet changers, bar feeders, robot cells
  • Freight, rigging, installation and training
  • Region, dealer and time of year

Overview

The Palmary PCB-6020-3 is a 3-axis CNC centerless grinder with a Ø610 mm grinding wheel, 205 mm wide, on a bearing-type spindle. Its standard range is Ø2 to Ø80 mm, with Ø70 to Ø150 mm as an option.

The suffix is the axis count. Palmary describes the design as 3 axes of CNC control, extendable up to 6, built for high grinding accuracy and rigidity. Lower and upper slides are square slides moved by ball screw and reducer.

A Ø610 mm wheel is a third larger than the wheel of the PCB-4520, and the weight shows how much more machine stands behind it: 5,800 kg (12,787 lb). The regulating wheel is Ø330 mm by 205 mm, runs at 10 to 200 rpm, tilts ±5° and swivels ±0.5°. Wheel speed is 45 m/s (8,858 ft/min).

On one point the published table is no help. The rows that should give the grinding and regulating wheel motors are printed under lubrication labels, so this page leaves the motor ratings out; get them from the quotation. What the table does state clearly is the lubrication itself, oil mist for the grinding wheel spindle and grease for the regulating wheel spindle, and a 125 L (33.0 gal) coolant tank.

A FANUC CNC controller is standard. Palmary offers a high-speed loading and unloading attachment, custom loading devices and an outer diameter measuring device as options.

Frequently Asked Questions

01 What does the "-3" mean in Palmary PCB-6020-3?

Palmary describes the machine as designed for 3 axes of CNC control, with up to 6 axes possible. The related PCB-6020GF-4 is described as a 4-axis machine. The page does not list which three axes are fitted.

02 What is the grinding range of the PCB-6020-3?

Ø2 to Ø80 mm as standard, with Ø70 to Ø150 mm listed as an option. The grinding wheel is Ø610 x 205 mm on a 304.8 mm bore and the regulating wheel Ø330 x 205 mm on a 152.4 mm bore.

03 What motor does the PCB-6020-3 have?

The specification table on Palmary's page prints the motor rows under lubrication labels, so the ratings are not reproduced here. Ask Palmary to confirm the grinding wheel and regulating wheel motors for your configuration.

04 How does the PCB-6020-3 differ from the PCB-6025-3?

The PCB-6025-3 has 255 mm wide wheels and a 140 L (37.0 gal) coolant tank. The PCB-6020-3 has 205 mm wide wheels and a 125 L (33.0 gal) coolant tank. Both are listed at 5,800 kg (12,787 lb).
