We do not have a price for the Campbell Grinder 750D1000 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 Campbell Grinder 750D1000 is a CNC vertical ID/OD grinder for cylindrical parts, with a swing diameter of 1,100 mm (43.3 in) and a part height of 550 mm (21.7 in). Campbell builds the 750 series specifically for this kind of part and names bearings, aerospace and power generation as the industries where the design has been successful.
The part stands with its axis vertical on a rotary table driven at 150 RPM. Campbell's point is that this removes the need for a steady rest or tailstock, since a ring sits flat on the table instead of hanging from a chuck. The base machine has two CNC axes, X and Z, each with an accuracy of 5 microns (0.0002 in).
The grinding spindle runs from 1,500 to 7,200 RPM and is an OD/ID spindle as standard. Roller ways and linear glass scales are fitted on all axes, the dresser is a single point unit, and the control is a FANUC CNC.
From there the machine is extended by options. Campbell states that it is available with up to five axes of motion: a B-axis spindle swivel and a high speed C-axis are on the list, as are an ID shoe for bearing grinding, a CDCF dresser, a magnetic chuck and a hydrostatic table bearing. An optional tool changer changes out wheels, tools and coolant nozzles.

Frequently Asked Questions
01
The table gives a swing diameter of 1,100 mm (43.3 in) and a part height of 550 mm (21.7 in). Campbell's documents do not agree on the diameter of the table itself, so confirm the table and fixture size with the maker for your part.
02
Two in the base specification, X and Z. Campbell says the machine is available with up to five axes of motion, and the option list includes a B-axis spindle swivel and a high speed C-axis. The table drive of the base machine runs at 150 RPM.
03
An OD/ID grinding spindle with a speed range of 1,500 - 7,200 RPM. A chiller with spindle loop is on the option list, and an optional tool changer changes out wheels, tools and coolant nozzles for specific part features.
04
Campbell describes the 750 as a highly rigid platform configured to machine a part with its axis vertical. In that position the part needs no steady rest or tailstock, which the maker says enhances accuracy and repeatability. The stated accuracy of both the X axis and the Z axis is 5 microns (0.0002 in).
