Correct measurement is essential for perfect results. It is the reference that defines the machining height, alignment and stability.
When measuring a vacuum cup, the only valid reference point is the support surface on the machine.
In practical terms: the correct height of a vacuum cup is the distance from the machine’s support surface to the point where the panel rests under working conditions. Anything else creates cumulative height errors, affects alignment and introduces instability in machining.
In modular vacuum systems, height is not just a specification. It is a structural reference that determines precision. Understanding how to measure it correctly is fundamental when selecting or configuring a system. You can explore our full range of modular vacuum blocks and cups here.
Because Vacuum CNC systems are built around a base + interchangeable cup architecture, height can be adapted without replacing the entire unit. This modular approach eliminates cumulative errors and allows fast configuration changes directly on the CNC table. Discover how our system works in detail.
Correct measurement is not a detail. It is the structural reference that defines machining height, alignment and long-term stability. When the reference point is clear, precision becomes repeatable. When it is not, small errors accumulate and compromise performance. In CNC workholding, speed and stability do not start at the spindle: they start at the support surface. Precision begins with the right reference.
