Sequence of operations

Comments

1. Preparing work materials, position reference faces to workpiece.

Check the completeness and sound condition of the workpieces, aids and machine.

2. Arrest the cutter arbor and fix the circular saw blade between two chucking disks to the milling arbor, subsequently remove the catch.

Use a milling arbor (without top bearing tenon) of 25 mm.

3. Fold width = 13 mm to be set, following setting again lock the milling support.

Tool running direction must ensue counter to direction of feed (counter rotation); use sharp tools only!

4. Set the stops of the guide rule in line with the machine tool diameter.

Loosen milling support and set the spindle height at 13 mm between machine table and saw blade top edge.

5. Fold depth = 5 mm to be set, arrest the guide rule after setting.

Set the workpiece in parallel position to the guide rule by the saw blade. Ensure a fold depth of 5 mm.

6. Steel strip deflector is attached to the guide rule.

Position the steel strip deflector about 8 mm above the workpiece. The steel strip deflector should prevent hand contact with the turning workpiece.

7. Check the machine in respect of labour safety requirements.

Ensure that the work table is in a clean condition. Check once again that the tool, stop and steel strip deflector are properly secured. Check the unimpeded running of the spindle.

8. Switch on the exhaust device, switch on the main switch of the machine. Preselect a spindle speed of 3000 min^-1 and then switch on the machine.

Ensure the correct rotational direction of the spindle. A wrong rotational direction can cause serious accidents!

9. Saw the first indentation for the fold.

Place the workpiece with the wide reference face onto the machine table and position the tool in line with the stop rule. Ensure that the hands are kept clear of the tool working area.

10. Switch off the machine and the exhaust facility.

11. Set up the machine for cutting out the fold depth.

Remove the steel strip deflector. Setting ensues are for the work steps 3., 4. and 5., whereby at the milling support the fold depth is set at 5 mm between the top edge of the saw blade and the machine table. The fold width of 13 mm is set at the guide rule.

12. Fix the pressure comb to the machine table.

The workpiece shall be lightly and evenly pressed to the stop face of the guide rule.

13. Check the machine in respect of adherence to labour safety requirements.

Ensure that the work table is in a clean condition. Check once again that the tool, stop and pressure comb are properly secured. Check the unimpeded running of the spindle.

14. Switch on the machine.

15. Saw the second indentation for the gold.

Place the workpiece with the narrow reference face onto the machine table and position the tool in line with the stop rule. Ensure that the hands are kept clear of the tool working area. Watch out! Do not remove residue material manually. Danger of accidents.

16. Switch off the machine, main switch and exhaust device.

17. Check the fold dimensions and control quality parameters.
