Mechanical Cutting Head Setup Optimax / Formline

When changing the cutting head on an Optimax / Formline you must ensure that the following points are observed and controlled:

• The basic height of the cutting head should be set up so that the head, when extended, the head can be lowered to approximately 1mm above the table top felt. It should at least be able to come down 1mm more than the top of the thinnest glass that you cut on the machine. The head must be high enough when retracted, to ensure that the thickest glass you cut on the machine can pass under the head with the transport belts up, without hitting the cutting wheel holder!

• To adjust the basic height of the cutting head you loosen the 4 bolts (two on each side of the head) holding the head in place and adjust the height by raising and lowering the complete head. With the cutting head in the UP position, the bottom of the pillar post to the felt should measure 32.5mm.

• Now you must ensure that the cutting head is exactly 90° to the table top. To do this place a piece of glass on the table and use an angle to control the settings and adjust if necessary.

• Now that the cutting head is mechanically setup so that the height and angle are correct you need to set the cutting wheel holder so that it is looking exactly down the long edge of the glass (90° to the bridge).

Twin Cutting Head setup

The twin cutting head is basically setup the same as a single head.

• First it is important to setup the “main” cutting head as described above. Once this has been done you can setup the second cutting head so that it is parallel to the main cutting head.
• Both heads should be set to the same height and be exactly 90° to the glass !
• The distance between the main turning shafts of the two heads should be 130mm +/- 1mm
• The Power grip drive belt 350 5MGT (pos.26) should then have the correct tension. The Power grip belt has equal addendum teeth that fit exactly into the two belt sprockets. This allows you to run with a low tension belt without having positioning deviation problems.
• Attention if the belt tension is too high this may cause contouring errors on the C-Axis drive !
• If it is necessary to adjust the second cutting head position you must check the offset value set in the Hegla.ini file (C:\stdmmi\hegla.ini).

[HilfsSchnitt]

WKZ_Offset_X=-129.7 this is the distance from the main cutting head to the second head in X direction in mm
WKZ_Offset_Y=0 this is the distance from the main cutting head to the second head in Y direction in mm
