- Reproducible zero point for workpiece and fixture.
- Workpiece changes in seconds — set-up often in parallel with machining time.
- Repeatability in the µm range, ideal for automation and pallets.
What is a zero-point clamping system?
A zero-point clamping system defines a fixed, reproducible reference position — the zero point — on the machine table. Workpieces, fixtures, or pallets are changed in seconds with precise positioning via clamping pins.
Operating principle
A clamping module sits on the machine table, and a clamping pin on the workpiece or fixture. When the pin is inserted, the module centers and locks it with a defined pull-in force — always in exactly the same position.
What are the benefits?
- Shorter set-up times: changeovers in seconds, set-up often in parallel with machining.
- High repeatability: reproducible positioning in the µm range.
- Automation-ready: ideal for pallet and multi-machine operation.
When is it worthwhile?
Wherever changeovers are frequent, many variants are produced, or production is automated. The set-up and alignment time saved usually pays for the system quickly.
Frequently asked questions
How much set-up time does a zero-point clamping system save?
Workpiece changes are shortened from minutes to seconds; in addition, set-up can often take place in parallel with machining time. The exact savings depend on part variety and quantities.
What repeatability can be achieved?
Standard systems achieve repeatability in the µm range — sufficient for demanding machining and measuring tasks.
