Workpiece processing bench

A workpiece processing system comprising:

• a moveable and demountable workpiece processing comprising:
• a hollow mounting beam for mounting equipment,
• a workpiece processing tool releasably mounted on the mounting beam,
• a positioning arm which is mounted movably in a longitudinal direction inside the hollow mounting beam and which includes a workpiece stopper at an end distal from the workpiece processing tool, and
• a drive unit, mounted on the mounting beam, comprising:
• displacement means configured to move the positioning arm to a desired position,
• wherein the displacement means comprises a gear drive, which engages in a rack of teeth on the positioning arm to move the positioning arm to a desired position;
• and
• a length control unit for controlling the displacement means, wherein the length control unit comprises:
• a length gauge configured to measure the length Lmeasured from the workpiece stopper to a predetermined surface of the workpiece processing tool;
• and
• a wireless communication unit configured to at least receive information from a user-controlled device about a desired length of Lworkpiece from a first end of a workpiece to a processing position on the workpiece,
• wherein the length control unit is further configured to position the workpiece stopper of the positioning arm at a desired length Lworkpiece from the workpiece processing tool, by moving the positioning arm until Lmeasured=Lworkpiece so that the workpiece can be processed at a desired length Lworkpiece from the first end of the workpiece when it rests against the workpiece stopper;
• and
• a user-controlled unit configured to send information about desired lengths for processing a workpiece to the wireless communication unit.

A method for using a moveable and demountable workpiece processing system comprising:

• a hollow mounting beam for mounting equipment,
• a workpiece processing tool releasably mounted on the mounting beam,
• a positioning arm which is mounted movably in a longitudinal direction inside the hollow mounting beam and which includes a workpiece stopper at an end distal from the workpiece processing tool, and
• a drive unit, mounted on the mounting beam, comprising:
• displacement means configured to move the positioning arm to a desired position,
• wherein the displacement means comprises a gear drive, which engages in a rack of teeth on the positioning arm to move the positioning arm to a desired position;
• and
• a length control unit for controlling the displacement means, wherein the length control unit comprises:
• a length gauge configured to measure the length Lmeasured from the workpiece stopper to a predetermined surface of the workpiece processing tool;
• and
• a wireless communication unit configured to at least receive information from a user-controlled device about a desired length of Lworkpiece from a first end of a workpiece to a processing position on the workpiece,
• wherein the length control unit is further configured to position the workpiece stopper of the positioning arm at a desired length Lworkpiece from the workpiece processing tool, by moving the positioning arm until Lmeasured=Lworkpiece so that the workpiece can be processed at a desired length Lworkpiece from the first end of the workpiece when it rests against the workpiece stopper;
• and
• a user-controlled unit configured to send information about desired lengths for processing a workpiece to the wireless communication unit, the method comprising:
• receiving, using the communication unit in the length control unit, a desired length Lworkpiece from the user-controlled unit,
• measuring, using the length gauge, the length, Lmeasured, from the workpiece stopper to a predetermined surface of the workpiece processing tool,
• moving the positioning arm using the displacement means until Lmeasured=Lworkpiece, if the length control unit registers that Lmeasured is different from Lworkpiece.
