Machine Comparison
Reishauer RZ 260 vs Reishauer RZ 550
Reishauer vs Reishauer · CNC Gear Cutting
Summary
The Reishauer RZ 260 and the Reishauer RZ 550 are both gear grinding machines from the same maker, and both run the Siemens SINUMERIK ONE control. Reishauer publishes few comparable figures for this pair, so the table holds only the control and the machine weight.
On weight, the Reishauer RZ 260 is listed at 9600 kg (incl. W-axis) and the Reishauer RZ 550 at 12,900 kg. Beyond that, the difference is the work each one is aimed at: the Reishauer RZ 260 at smaller gears and shaft-type parts in fine to medium modules, the Reishauer RZ 550 at larger and heavier gears, including coarse pitches done by profile grinding.
Specifications Comparison
| Specification | Reishauer RZ 260 | Reishauer RZ 550 |
|---|---|---|
| Control | Siemens SINUMERIK ONE | Siemens SINUMERIK ONE |
| Machine Weight | 9600 kg (incl. W-axis) | 12,900 kg |
Advantages
Reishauer RZ 260
- Lighter machine at 9600 kg (incl. W-axis) against 12,900 kg
- Aimed at smaller gears and shaft-type parts in fine to medium modules
Reishauer RZ 550
- Aimed at larger gear diameters and heavier workpieces
- Suits job and batch work that mixes generating and profile grinding
- Covers coarse pitches by profile grinding
Verdict
Choose by gear size. A shop grinding smaller gears and shaft-type parts fits the Reishauer RZ 260, the lighter machine at 9600 kg (incl. W-axis). A shop with larger gears, coarse pitches, or mixed job and batch work that calls for both generating and profile grinding fits the Reishauer RZ 550 at 12,900 kg. Both use the Siemens SINUMERIK ONE control, so the control is not a deciding factor.
