Flat shape
|
|
|
|
 |
The U-shaped design is generally used in a horizontal, lying position for milling table guides. With this design the maximum width of the telescopic cover should be limited to 1.5 m.
|
|
|
|
Roof shape, centric (eccentric)
|
|
|
|
 |
This design is always advisable when cooling lubricants are used. The inclined surface allows the water and naturally also the chips to run off more easily. With large covers (> 3 m width) for reasons of stability, etc. at least three roof angles should be provided.

Flattened roof shape
|
|
|
|
 |
The flattened roof shape is a special construction method with two roof angles. Primarily for dry operation and widths > 3 m.
|
|
|
|
Shape with incline to one side
|
|
|
|
 |
The shape with incline to one side has a special roof shape. Depending on the possible incline, covers can be constructed with widths of up to 1.5 m. This shape is likewise a recommended solution when large amounts of coolant are present. Depending on the angle of incline, this form also helps to discharge coolants / chips.

Vertically-installed telescopic cover
|
|
|
|
 |
Standing covers are used on larger machine tools, mostly in the area above and below the cross beam. They can take many different shapes.
|
|
|
|
Cross-beam cover
|
|
|
|
 |
These covers are predominantly used on large gantry machine tools on a cross beam to the left and right of the support. The boxes are suspended vertically and protect the support guides from chips and cooling lubricants.

|
|
|
Blind cover
|
|
|
|
 |
With blind telescopic covers, the cover plates move in separate guide rails, each of which is mounted on the machine at the sides. It is used exclusively in a vertical arrangement. The guide rails are generally made of brass.

Tubular cover, polygonal cover
|
|
|
|
 |
Tubular covers or covering shafts, spindles, etc. They can be made either with a round or a polygonal shape.
