Processing

Widening

It is possible to widen the tube ends in the dimensional range from 5 to 75 mm.

Close

Notching

Down to a wall thickness of 2 mm pieces may be cut out on one side of the tube.

Close

Round Tube Components

Components from round tube can be provided in the dimensional range from 2 to 100 mm.

Close

Perforating

Perforations can be applied to almost any part.

Close

Bordering

Bordering means that the edges are doubled over. This process may be applied down to a wall thickness of 1.5 mm.

Close

Burr Removal With Brush

Outside diameter 8.0 to 50.0 mm, length 30 to 300 mm, wall thickness 1.0 to 4.0 mm. The rotating brushes will knock off the burr. This burr removal process is particularly suited for long parts.

Close

Turning

Outside diameter from 2 to 100 mm. Turned parts of up to 300 mm length.

Close

Machining Of Ends

Machining operation to remove burr and produce smooth, clean and angular tube ends but also for chamfering and special edge forms of all kind. The dimensional range for the outside diameter is from 8 to 80 mm.

Close

Degreasing

Tube ends can be PER-degreased in closed facilities.

Close

Burring

Equipment is available for both burr removal with brushes and grinding.

Close

Centrifugal Force Grinding

Outside diameter 2.0 to 3.0 mm, length 2.0 to 50 mm, wall thickness 0.2 mm to solid material. Centrifugal force grinding is a particularly intensive way of grinding.

Close

Chamfering

It is possible to chamfer the tube edges at the ends. By experience we recommend for most applications a rounding of the edges by grinding.

Close

Mitering

It is possible to miter on both sides starting with an outside diameter of 5 mm.

Close

Burr Removal By Grinding

Outside diameter 2.0 to 100 mm, length 2.0 to 250 mm, wall thickness 0.2 mm to solid material. Grinding rounds sharp edges. The burr is doubled over but not removed.

Close

Calibrating

The calibrating of tubes allows for very tight outside diameter tolerances.

Close

Laser Processing

In one operation it is possible to produce complex contours. This may allow you to do without further processing steps like perforating, punching, sawing and milling. Up to outside diameter of 150 mm, for square components 120 x 120 mm. Wall thicknesses: steel down to 6 mm, stainless steel down to 5 mm, aluminium down to 4 mm.

Close

Knurling

Knurls may be applied to tubes starting from a wall thickness of 1.5 mm.

Close

Cleaning

On alkaline base in steam degreasing plants and by ultrasound.

Close

Forming Of Tube Ends

Forming operations to tube ends in one or several steps for a local shaping of form elements of different kind. The different shapes of forming may be combined with each other.

Close

Sawing

Outside diameter 2.0 to 100 mm, length 2.0 to 500 mm, wall thickness 0.2 mm to solid material. Automatic precision saws guaranty edges and tolerances from ±0.05 mm, which have almost no burr.

Close

Slotting

Partial and even continuous slotting of tubes.

Close

Punching

Up to tube diameter of 70 mm.

Close

Heat Treatment

For the entire range of dimensions we offer heat treatments like

• Stress relief annealing
• Soft-annealing
• Standard annealing

Close

Washing

Outside diameter 5.0 to 100 mm, length 2.0 to 300 mm, wall thickness 0.2 mm to solid material. Surface impurities are removed in one washing operation.
