Zero Point Clamping System
The ZeroClamp zero point clamping system is the modern alternative to the conventional T-slot table: Drastically reduces the setup times and increases your machine capacity.
Maximum user-friendliness
Highest degree of accuracy
Repeat accuracy of less than 2.5 μm.
Simple logistics
Just one type of clamping stud.
The key benefit
Thermal symmetry.
No tilting
Uncomplicated joining and removing.
One system for the entire process chain
Milling, turning, right up to quality assurance.
-90 %
Reduce setup times by up to 90%
+ 330 h
Additional production time per year
Save
29,700 euros per year
Assumption: 2 setup processes/shift; 2 shifts; 220 work days/year; machine-hour rate €90.00
Setup processes in comparison
Conventional setup process
1. Clean the machine table
2. Clean the clamping device contact surfaces
3. Position via the slot nuts
4. Align
5. Fasten with clamping screws
6. Determine the zero points
7. Start the program
8. End the program
.
Disadvantage:
It is difficult or even impossible to interrupt the process (completely remove the component from the machine table).
→ Machine standstill or workpiece is scrapped.
ZeroClamp setup process
1. Clean the machine table (reduced)
2. Clean the clamping device contact surfaces
Biggest time factor completely omitted!
3. Start the program
4. End the program
Benefit:
The process can be interrupted without a problem at any time.
→ Continued machine use.
Multiple benefits for day-to-day production work
Milling
Direct clamping of the component onto a base unit. Holes as sockets for the clamping studs are specified at the design stage. Components can be changed quickly and accurately (across all machines).
Turning
In the case of turning operations as well, the productivity increases are used to best advantage with pre-balanced base units. Maximum safety with high forces thanks to additional retaining elements.
Spark erosion
Functions reliably even under water or in dielectric. The base units are equipped with special drain holes so that the water can escape when the pots are opened.
Quality assurance
There are also setup and non-productive times during measuring which can be reduced. Furthermore, the machining process can be interrupted for intermediate measurements on the measuring machine (the clamping studs are not removed for this purpose) before continuing with the process.
The center piece
Simple assembly with few components and very high repeat accuracy for at least one million cycles!
Pneumatic System:
Only 5.5 bar air pressure is required to release the clamping studs.
For comparison: classical systems
Difficult compensation for thermal expansion
Too much clearance
Positioning via a cylindrical or conical clearance fit.
Example of stud/socket clearance fit:
Ø 35 h5/H5 = 22 µm.
ZeroClamp thermal symmetry and accuracy
Thermal symmetry –
Fixed zero point in the center of the table
Compensation for thermal expansion always symmetrical about the center axis.
Fixed zero point in the center of the table: Pitch errors can be compensated up to ±0.05 mm per clamping pot.
Highest degree of accuracy –
Clearance-free fit
Clearance-free fit enables a perfect form fit with a repeat accuracy of less than 2.5 μm.
The hyperstatic interface ensures axial face contact and zero radial clearance.
The ZeroClamp benefit
Easy to handle from a logistical point of view.
No differentiation between zero pins, floating pins, and free pinsJust one clamping stud type required!
