Our best estimate for a cnc gear cutting machine in this class — not a quote from Reishauer. Configuration moves it a long way.
Overview
The Reishauer RZ 1000 is a gear grinder for large workpieces: diameters from 60 mm to 1000 mm, shafts up to 800 mm long and a maximum workpiece weight of 1200 kg. It grinds by two processes. Generating grinding covers modules of 0.5 – 10.0 mm, and profile grinding extends the range to 0.5 – 14 mm.
Size is the reason to choose it, but the working stroke deserves a close look. The maximum grinding stroke is 300 mm, so the gearing itself, with run-in and run-out, has to fit inside that stroke even when the shaft carrying it is 800 mm long. The grinding head swivels ± 45°, which bounds the helix angles that can be ground. Tooth counts from 5 to 800 are covered.
The grinding wheel is up to 300 mm in diameter and 145/160 mm wide, and runs at a maximum operating speed of 80 m/s. Dressing rolls are 123 – 160 mm in diameter. The work spindle turns at up to 600 min⁻¹, a figure that fits big gears with many teeth, which rotate slowly against the wheel.
The control is a Siemens SINUMERIK ONE. On-board measuring with closed loop functionality appears under hardware options, so specify it at order instead of assuming it. At 15,500 kg the RZ 1000 is heavier than the RZ 550 at 12,900 kg, which runs the same control.

Strengths & Limitations
Strengths
- Takes workpieces from 60 mm to 1000 mm in diameter and up to 1200 kg
- Two processes on one machine: generating grinding for modules of 0.5 – 10.0 mm and profile grinding for 0.5 – 14 mm
- Grinding head swivels ± 45°, and tooth counts from 5 to 800 are covered
- Maximum operating speed of 80 m/s with a grinding wheel up to 300 mm in diameter
- Siemens SINUMERIK ONE control, the same control listed for the RZ 550
Limitations
- Grinding stroke is 300 mm at most, well short of the 800 mm maximum shaft length
- Work spindle speed tops out at 600 min⁻¹
- On-board measuring with closed loop functionality is a hardware option
- Workpieces under 60 mm in diameter are below the stated minimum
- At 15,500 kg the machine needs foundation and rigging planned around it

Frequently Asked Questions
01
Workpiece diameter runs from 60 mm to 1000 mm, shaft length up to 800 mm and workpiece weight up to 1200 kg. The number of teeth can be anywhere from 5 to 800. The maximum grinding stroke is 300 mm, which limits the length of gearing that can be ground on a long shaft.
02
It depends on the process. Generating grinding covers modules of 0.5 – 10.0 mm. Profile grinding covers 0.5 – 14 mm, so gears coarser than module 10.0 mm are ground by the profile method.
03
Reishauer lists on-board measuring with closed loop functionality under hardware options, so it is not part of every machine. If the process depends on measuring the gear on the machine and feeding corrections back, make sure the option is on the order.
04
The grinding wheel has a maximum diameter of 300 mm and a width of 145/160 mm, with a maximum operating speed of 80 m/s. Dressing rolls are 123 – 160 mm in diameter. The grinding head carrying the wheel swivels ± 45°.
05
On the figures available for both, the RZ 1000 weighs 15,500 kg against 12,900 kg for the RZ 550, and both run the Siemens SINUMERIK ONE control. What defines the RZ 1000 is its 1000 mm maximum workpiece diameter and 1200 kg workpiece weight.
