Spin windows 

Our spin windows clear the view
When machine tools are in operation, the view into the interior is severely restricted by flying chips and cooling lubricant splashing around.
Our SPINVISTA ensures a clear view of the manufacturing process:
It rotates at such a high speed that liquids and debris are kept away from the disc. The result is a clear view of the manufacturing process.
The SPINVISTA is available in two versions:
SPINVISTA EVO with an outside diameter of 253 mm and a visible area of approx. 284 cm²
SPINVISTA NEO with an outer diameter of 290 mm and a visible area of approx. 430 cm²

SPINVISTA - also for particularly demanding applications

High-quality materials are used in our SPINVISTA. The housing surface consists of hard anodized aluminum and is therefore resistant to abrasion and has excellent thermal conductivity.
If required, we can also equip the SPINVISTA with ATEX protection; the motor and electronics are fully encapsulated and are thus protected against sparks and moisture. 

Diverse installation options

The SPINVISTA pivot windows from HEMA can be attached to both windows and operator doors. Thanks to the flat design, it can be adapted to a wide variety of window or door designs, and if there is enough space, it can even be attached to sliding doors. The SPINVISTA can be mounted at any angle of rotation, and there are three positions to choose from for the connections to the connection box.

The operating principle of spin windows

Spin windows make use of centrifugal force: It moves dirt and liquids away from the center of the pane and enables a clear view into the interior of the machine.

Which coolants is SPINVISTA suitable for?

The SPINVISTA offers the best view of the manufacturing process in systems in which water-based coolants or thin-bodied mineral oils are used. On request, you can find out which oils the turning window is suitable for. In environments with oil-based coolants, we also recommend using a disc with a special coating.

Machine Safety Windows

During machining, chippings are produced that can be swirled around inside the machine. It can also happen that tensioned workpieces are loosened or a tool breaks off due to incorrect operation and flies through the workspace with great force. Therefore, the use of a safety window is recommended to protect the operating personnel. If only simple polycarbonate windows are used in the equipment of machine tools, they quickly become brittle due to the permanent contact with coolants and lose their retention force. For this reason, HESTEGO uses a combination of safety glass and polycarbonate for the manufacture of its machine safety glass. In general, we recommend the replacement of machine safety windows after a period of use of 5 years based on the recommendations of the employers' liability insurance association and the VDW.

Our service - from advice to installation
• We will advise you on the upcoming replacement of your machine safety panes
• We replace your machine safety pane
• We retrofit your old machine according to the current safety requirements for machine safety panes
• We keep track of things for you - and remind you to replace the lenses in the frame in good time

Impact tests

Our machine safety windows have been designed according to the standards for cutting machine tools.
By their encapsulation and sealing, the safety windows are permanently and effectively protected against external influences.
The retention capacity is tested at external institutes in accordance with the applicable standards for machine tools. Therefore the safety windows are bombarded with projectiles weighing up to 2.5 kg and hit the disc at a speed of up to 80 m / s and an energy of up to 8,000 Nm.
If they come into contact with aggressive cooling lubricants, polycarbonate panes without additional protection lose their safety restraint function partially or completely after just a few months of use. This is why HESTEGO manufactures its machine safety panes as composite safety panes made of polycarbonate and safety glass.
