SEMA deburring machine types - The right machine for every deburring application

Every deburring machine from SEMA Machine Tools is specially adapted to the customer wishes and production conditions. In the area of deburring, a distinction is made between the following machine types:

Rotary transfer deburring machines

 - For short machining times and multiple deburring steps

Deburring with the SEMA rotary transfer machine

The rotary transfer machines can be equipped with 2 to 12 stations. The first station is always the workpiece clamping position. The other stations can be equipped with various machining units, such as: milling spindle, planetary deburring head, turning device, brush unit, etc.

The rotary table is situated in the middle of the machine. The individual clamping mechanisms for the workpieces are mounted to this. The individual machining units are situated outside, around the rotary table. The machining units are mounted to NC feed axes (1-axis, 2-axis, 3-axis or 4-axis).

The system is operated from a swivelling control panel. Large sliding doors ensure optimal access to the individual machining units for equipping and changing tools.

End deburring machines

- For cylindrical and shaft-shaped parts

The machines are designed for longer workpieces up to a maximum length of 2,500 mm. The workpieces are clamped between two tips, with one tip on the drive side and the counter-tip following.

Depending on the machining required, several different machining units can be mounted in this case as well. These are also attached to NC feed axes (1-axis, 2-axis, 3-axis or 4-axis).

The machine can be equipped either from the front or from above.

Flexible deburring cells

- For complex machining contours

These deburring machines are equipped with a robot for handling either the workpieces or the tools. This choice depends mostly on the part size or the number of machining tools. The robot cells are completely covered so that the cell can be connected to an external vacuum system.

The workpieces can be brought to the robot cell on a conveyor belt, stack magazine, tray or individually.

Workpiece handling: The robot grips a workpiece from a defined position and holds the workpiece precisely against the fixed deburring spindles. Various deburring spindles can also be used here (brush, milling and other deburring spindles). A turning device or SPC and defective parts tray can be additionally integrated into the cell.

Tool handling: The workpiece is clamped in a fixed position. The robot makes use of a tool magazine and holds the various tools precisely against the workpiece. Tool handling offers less flexibility in terms of tools because the dimensions and weights of the tools (including motor) are limited.

Single-spindle deburring machines

- For larger parts and smaller lot sizes

Single-spindle deburring machine with milling pins from SEMA

These machines have been designed for larger workpieces with a maximum workpiece diameter of 800 mm. The central tool clamping spindle is situated in the centre of the machine.The individual machining units are installed around the outside of the workpiece spindle. The machining units are mounted to NC feed axes (1-axis, 2-axis, 3-axis or 4-axis). Depending on the machining requirements, various machining units can also be used here.

The machine can be equipped either from the front or from above.
