How much does the Reishauer RZ 160 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
The Reishauer RZ 160 is a continuous generating gear grinding machine for small gears and geared shafts: gear outside diameters up to 162 mm (6.4 in), modules of 0.5 – 4 mm and a workpiece weight of no more than 30 kg (66 lb). Reishauer designates the current version RZ 160 4.0.
The weight limit is the figure to check first, because the 30 kg (66 lb) includes the fixture. A heavy clamping arbor comes straight out of what is left for the part. Inside that limit the machine accepts shafts up to 490 mm (19.3 in) long with a maximum grinding stroke of 180 mm (7.1 in), so a long transmission shaft fits as long as its gearing sits within the stroke.
The work spindle runs at 3,000 min-1 and the maximum grinding speed is 100 m/s. In continuous generating the work spindle has to keep step with the wheel, so a fast work spindle is what allows gears with few teeth to be ground at full wheel speed. The grinding wheel is up to 275 mm (10.8 in) in outside diameter with a face width of 125 or 160 mm, the dressing tool is 123 or 140 mm in diameter, and the grinding head swivels ±48°.
The machine weighs 9,600 kg (21,164 lb). It is lighter than the RZ 550 at 12,900 kg and the RZ 1000 at 15,500 kg.

Strengths & Limitations
Strengths
- Maximum grinding speed of 100 m/s with a work spindle speed of 3,000 min-1
- Shafts up to 490 mm (19.3 in) long fit, with 180 mm (7.1 in) of grinding stroke
- Grinding head swivel angle of ±48° for helical gears
- Grinding wheel face width of 125 or 160 mm on a wheel up to 275 mm (10.8 in) in outside diameter
- Covers modules of 0.5 – 4 mm on gears up to 162 mm (6.4 in) outside diameter
Limitations
- Workpiece weight is limited to 30 kg (66 lb) including the fixture
- Gear outside diameter stops at 162 mm (6.4 in) and module at 4 mm
- Grinding stroke of 180 mm (7.1 in) is far shorter than the 490 mm (19.3 in) shaft length, so only part of a long shaft can be ground

Frequently Asked Questions
01
The maximum gear outside diameter is 162 mm (6.4 in) and the module range is 0.5 – 4 mm. Shafts can be up to 490 mm (19.3 in) long, and the maximum grinding stroke is 180 mm (7.1 in).
02
30 kg (66 lb), and that figure includes the fixture. Weigh the clamping arbor or fixture first and subtract it, because what remains is the real limit for the part.
03
The grinding wheel has a maximum outside diameter of 275 mm (10.8 in) and a face width of 125 or 160 mm. The dressing tool diameter is 123 or 140 mm. The table gives two values for each without saying which is standard, so settle the choice with Reishauer when ordering.
04
The maximum grinding speed is 100 m/s and the work spindle speed is 3,000 min-1. The grinding head carrying the wheel swivels ±48°.
05
The RZ 160 weighs 9,600 kg (21,164 lb). That is less than the RZ 400 at 14,000 kg (30,865 lb), but it is still a load that calls for a checked floor and a rigging plan.
