Price estimate
We do not have a price for the Campbell Grinder 930E750 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 930E750 is a 5-axis CNC vertical creep feed grinder with a 750 mm (29.5 in) table and a part height of 750 mm (29.5 in). It is the largest 930 model whose spindle is listed at up to 60 HP (44.7 kW).
Campbell describes the 930 as its traveling column vertical grinder combined with a 5-axis layout, and the structure is what the buyer is paying for at this size. The frame is a large box section, built for stiffness and machine geometry. The column moves in X, Y and Z on precision roller ways, and all three axes are driven by linear motors, so there are no screws to wear in a machine that spends its life under creep feed loads.
Feedback is direct, from linear glass scales. The stated accuracy is 5 microns (0.0002 in) for each linear axis and 10 arc seconds for both the C axis table spindle and the B axis spindle swivel. On a part this wide an angular error at the table grows with the radius, which makes the rotary figure the one to study.
The grinding spindle is direct drive and liquid cooled, and the machine is fully enclosed. A high-speed C-axis rotary table, a spindle mounted dresser with dress roll changer and a wheel balance system are among the options. The control is a Fanuc 31i.

Strengths & Limitations
Strengths
- 750 mm (29.5 in) table and 750 mm (29.5 in) of part height
- Linear motors on X, Y and Z
- Large box section frame for stiffness and machine geometry
- Direct feedback from linear glass scales on all axes
Limitations
- Spindle power is up to 60 HP (44.7 kW), where the 930E1000 is listed with up to 100 HP (74.6 kW) at the same part height
- Rotary axis accuracy is 10 arc seconds, which matters more as the part radius grows
- The high-speed C-axis and the spindle mounted dresser are options

Frequently Asked Questions
01
The table is 750 mm (29.5 in) and the part height 750 mm (29.5 in). The 930E1000 has a 1,000 mm (39.4 in) table but the same part height, so this is already the tallest envelope in the series.
02
X, Y and Z are driven by linear motors and guided on precision roller ways. The rotary axes are the C axis table and the B axis spindle swivel. Position feedback is direct, and linear glass scales on all axes are part of the standard feature list.
03
The catalogue gives 5 microns (0.0002 in) for each of the X, Y and Z axes, and 10 arc seconds for the C axis table spindle and for the B axis spindle swivel. The product page for the model prints a different rotary figure, so have Campbell confirm it in the quotation.
04
Campbell lists disk and roll form dressers, a spindle mounted dresser with optional dress roll changer, a wheel balance system, part and tool probing, a tool and nozzle changer, milling and drilling, coolant through the tool and a high-speed C-axis rotary table.
