Observing the actual machining process in the CNC machine without
being impacted by coolant or chips can optimise manufacturers’ processes
and improve working ergonomics and productivity. Especially during
intensive coolant use, clear visibility can increase workers’
productivity by reducing the time taken for setup and prove-out.
machines prevent the door being opened during operation for safety
reasons, which makes it difficult for operators to view operations and
cutting conditions. Despite high quality coating of the machine windows
and modern machine tool design, they still need a “windscreen wiper”, a
spin window or rotary wiper, which cleans the window by centrifugal
Dimac Tooling offers the integration of one of the most
modern intelligent spin window solutions, the Pioneer rotary wiper spin
window. The spin window is designed to provide visibility into machines
with coolant system pressures of up to 80 bar, such as those found on
through-tool coolant delivery systems. It comes standard with
carbon-coated glass for resistance to chip activity and low maintenance
A spinning disk is mounted on the machine side, giving
clear vision to the process by its high rotational speed (2000 rpm). The
window features a built-in chip protection with specially designed base
and disc ring.
Normal installation requires no holes in the machine
tool window and increases the life of polycarbonate safety panels. A
high-tech adhesive sheet is used for bonding the spin window to the
desired position. Additionally, the systems help address safety concerns
because users have no need to bypass machine interlocks. Operators can
view the process while remaining behind the safety window of the
The compressed-air-driven spin windows are suitable for
all types of CNC milling machines, lathes and machining centres, both in
original equipment and for retrofitting. Simple installation and
optimum maintenance due to modular design reduce the costs.
