Product Details
The KERN Pyramid
Nano has been developed for applications which require maximum
accuracy and surface finish on larger workpieces. An integrated
automatic workpiece changer allows unmanned operations even for 5
axes simultaneous jobs.
Virtually Perfect Nano Precision
The precision of the Kern Pyramid Nano goes beyond nano precision
with positional accuracy within ± 0.3µm. To
demonstrate the accuracy of the Kern Machining systems with
Hydrostatic drives, Kern was able to drill five consecutive holes
into an actual hair from a Kern Employee. Not only is the Kern
Pyramid Nano able to successfully position over the hair, it is
able to make a clean hole through the hair because of how
vibration free it is.

The
KERNPyramid Nano is a cost effective nano precision maching and
large volume cutting amchine. With precision features such as a
laser tool length measuring system, touch probe system with
infared transmission and hydrostatic axes and guideways the Kern
Pyramid Nano is able to tackle precision machining operations
other machines simply can’t handle.
The
KERNPyramid Nano is perfect for making rapid prototypes, die and
tool making as well as precision molds. The nano µm
precision is perfect for making difficult to make parts.
Hydrostatic drives and
guideways
The hyrdostatic drives and guideways of the Kern Pyramid Nano
allow for the most accurate surface finishing. The hydrostatic
drives are also able to provide fast acceleration with maximum
vibration dampening.
Advantages of the hydrostatic system:
- Finest surface finishes with hydrostatic dampening
- Smallest movements of the axes 0.1µm
- Wear-free guideways and drives
- Almost frictionless movements . no “slip stick” effect, even
when moving in small increments - Low sensitivity at high machining forces
- High dynamic rigidity
- Permanently cooled circulating hydraulic oil flows through
axes, drives and machine frame - The highly dynamic third axis construction does not require
counter-balance weights - All motors are mounted outside of the axes – thus minimizing
possible temperature influence - Approx. 50% lower energy costs in comparison to linear drives
- No unacceptable cogging effects, as seen with linear drives
