Overview
The Reishauer RZ 260 is a CNC gear grinding machine for workpieces from 19 to 262 mm in diameter, in modules from 0.5 to 5.0 mm. Reishauer's table puts three more limits on the part: a shaft length of up to 490 mm, a maximum grinding stroke of 180 mm, and a workpiece weight of 50 kg that includes the workholding.
Read those three limits together. The 50 kg covers the arbor or clamping fixture as well as the gear, so heavy workholding comes straight off what is left for the part. A solid steel gear close to 262 mm in diameter gets heavy quickly, which makes weight the thing to check before the dimensions on larger parts. A shaft may be 490 mm long, but the stroke is 180 mm, so the toothed section and the run-in and run-out around it have to sit inside that distance.
The grinding head swivels ± 48°, which bounds the helix angles that can be set. The workpiece turns at up to 1600 min⁻¹ and the maximum operating speed is 100 m/s. On the tooling side the grinding wheel is up to 275 mm in outside diameter and 125 or 160 mm wide, and the dressing tools are 123 or 140 mm in diameter.
The control is a Siemens SINUMERIK ONE. The machine measures 2880 x 2310 x 2920 mm (width x depth x height) and weighs 9600 kg including the W-axis. For parts beyond its limits, the RZ 800 is listed for workpieces up to 800 mm and 1,200 kg at a machine weight of 15,500 kg.

Strengths & Limitations
Strengths
- Covers workpiece diameters from 19 to 262 mm and modules from 0.5 to 5.0 mm on one machine
- Shafts up to 490 mm long fit, with a maximum grinding stroke of 180 mm
- Grinding head swivel angle of ± 48° for helical gearing
- Workpiece speed up to 1600 min⁻¹ with a maximum operating speed of 100 m/s
- Siemens SINUMERIK ONE control
Limitations
- Workpiece weight is limited to 50 kg, and that figure includes the workholding
- The 180 mm grinding stroke covers only part of a 490 mm shaft, so long gearing or widely spaced gears on one shaft may not be reachable in one setup
- Module stops at 5.0 mm and diameter at 262 mm; the RZ 800 is listed to 10 mm module and 800 mm
- Wheel width (125 / 160 mm) and dressing tool diameter (123 / 140 mm) are each listed as two values, with no indication of which is standard

Frequently Asked Questions
01
Workpiece diameters from 19 to 262 mm and modules from 0.5 to 5.0 mm. Shafts can be up to 490 mm long, and the maximum grinding stroke is 180 mm, so the gearing on a long shaft has to lie within that stroke.
02
50 kg, including the workholding. Weigh the arbor or fixture first and subtract it: what remains is the real limit for the gear or shaft. On parts near the 262 mm diameter limit this is usually the figure that decides whether the job fits.
03
The grinding head has a swivel angle of ± 48°, in both directions. That is the range available for setting the wheel to the helix of the gear, so check the helix angle of the part against it together with the 180 mm grinding stroke.
04
Reishauer lists a Siemens SINUMERIK ONE as the control. The table gives the control by name only and no further control features, so anything specific you need from it should be confirmed in the quotation.
05
The RZ 800 is the machine for much larger work: workpieces up to 800 mm in diameter and 1,200 kg, with a 300 mm grinding stroke. The RZ 800 weighs 15,500 kg against 9600 kg including the W-axis for the RZ 260. The RZ 260 runs the workpiece faster, 1600 min⁻¹ against 600 min⁻¹ on the RZ 800.
