How much does the Reishauer RZ 260 cost?
Estimated price range
Our best estimate for a cnc gear cutting machine in this class — not a quote from Reishauer. Configuration moves it a long way.
Overview
Reishauer's RZ 260 is a gear grinder built around a grinding wheel of up to 275 mm outside diameter, a maximum operating speed of 100 m/s and a Siemens SINUMERIK ONE control. Its working range is gears of 19 – 262 mm diameter in modules of 0.5 – 5.0 mm.
Two rows of the table are choices, not fixed values. Grinding wheel width is given as 125 / 160 mm and the diameter of the dressing tools as 123 / 140 mm. Wheels and dressing tools are consumables that must match the machine as built, so pin down which width and which dressing tool diameter the machine is configured for before buying tooling for it. This matters just as much on a machine that changes hands.
For installation, the footprint is 2880 mm wide by 2310 mm deep, and the height of 2920 mm is the dimension to compare with door openings and the crane hook. Weight is 9600 kg, a figure that already counts the W-axis. The RZ 160 is listed at the same 9600 kg with the same control, so the foundation and rigging are no lighter for choosing the smaller model. The RZ 550 is listed at 12,900 kg.
On the workpiece side the limits are modest: 50 kg including workholding, a shaft length of 490 mm, a grinding stroke of 180 mm, and a workpiece speed of 1600 min⁻¹. The grinding head swivel angle is ± 48°.

Strengths & Limitations
Strengths
- Maximum operating speed of 100 m/s on a grinding wheel up to 275 mm in outside diameter
- Grinding wheel width can be 125 or 160 mm, with dressing tools of 123 or 140 mm diameter
- Footprint of 2880 x 2310 mm at a machine weight of 9600 kg including the W-axis
- Module range of 0.5 – 5.0 mm across gear diameters of 19 – 262 mm
- Runs the Siemens SINUMERIK ONE control, the same control listed for the RZ 160 and RZ 550
Limitations
- Only 50 kg of workpiece weight, workholding included, on a 9600 kg machine
- Machine height of 2920 mm needs checking against doors and crane clearance before delivery
- Operating speed, wheel diameter and wheel width are the only wheel figures listed; the table gives no drive power for the grinding spindle
- Grinding stroke of 180 mm limits the width of gearing that can be ground in one pass along the shaft

Frequently Asked Questions
01
The grinding wheel has a maximum outside diameter of 275 mm and a width of 125 or 160 mm. The maximum operating speed is 100 m/s. The table lists both widths without saying which one a given machine carries, so confirm it with Reishauer or on the machine.
02
The diameter of the dressing tools is listed as 123 / 140 mm, two sizes. As with the wheel width, the table does not say which is standard, so check the size fitted before ordering dressing tools.
03
The machine is 2880 mm wide, 2310 mm deep and 2920 mm high, and it weighs 9600 kg including the W-axis. Those are the machine's own figures; the table gives no figure for the space around it, so plan access for loading, wheel changes and service separately.
04
05
Workpiece diameter 19 – 262 mm, module 0.5 – 5.0 mm, shaft length up to 490 mm, grinding stroke up to 180 mm and a workpiece weight of 50 kg including workholding. The workpiece turns at up to 1600 min⁻¹ and the grinding head swivels ± 48°.
