Precise clamping down to
the nearest thousandth percent: With its high-precision power chuck of the HPF
series, the SAV Group provides a clamping device with a run-out reproducibility
of less than 0.003 mm.
SAV developed the 3-jaw
chuck with large throughput especially for use in machining technologies that
require the highest precision. This makes it the ideal clamping chuck for
cylindrical grinding, hard turning and precision turning with counter spindle
and suitable for internal and external stresses. Based on decades of know-how
in rotary clamping technology and high-precision manufacturing methods, the HPF
series of SAV achieves a run-out reproducibility of less than 0.003 mm.
The innovative jaw
interface, which was developed by the experts in the rotating clamping
technology especially for the HPF series, guarantees exceptionally precise
exchange reproducibility. The wedge hub connection between the base and
mounting jaw ensures that the rework of the clamping points is not required
after changing the jaw.
Low maintenance: no lubrication, less cleaning
A permanent lubrication and thus a constant clamping force ensures
the oil capacity. The clamping chuck is sealed against the penetration of dirt
and coolant as well as against the leakage of the lubricant and hence is
virtually maintenance-free. The design-optimised double-angle housing guides
the dirt away from the clamping point by using centrifugal forces. An
anti-stick coating also ensures that no dirt adheres to the chuck. The expense
for cleaning work is therefore significantly reduced.
Despite its lightweight design, the HPF series 3-Jaw
high-precision power chuck is particularly wear-resistant. Since selected
materials such as high-strength aluminium are used, customers benefit from a
long service life. The chuck is actuated by a force clamping cylinder.
