    1550 Inst Issue 6 05/09/06 6. Machine Controls All of the machine controls are located on the front control panel as shown in Diagram 3 below. Diagram 3. Machine controls 1. Emergency Stop Buttons. Disable all machine movements. Push to operate.
  • Page 9 1550 Inst Issue 6 05/09/06 11. Extraction Over-ride Switch. Switches on the Extraction system only, e.g. for swarf clearance while changing cutter hubs. 12. Hour Counter – Machine. Counts the Total Number of machine running Hours. This Counter cannot be reset.

  • Page 10: To Polish An Edge

    Select your piece of material The 1550 will accept pieces of material of thicknesses up to 55mm. Should you wish to polish thinner materials, these can be polished as packs up the 55mm maximum. The minimum panel size which should be polished is 100mm square. The ends of longer rods or bars of material can also be polished, but care should be exercised.

  • Page 11: Accessing The Cutter Area

    1550 Inst Issue 6 05/09/06 8. Accessing the Cutter Area The cutter area is accessed by opening the transport systems. Remove the four cap head screws (1) and (2) in Diagram 5 below. Note that screws (1) are much longer, as they extend down to contact interlock microswitches beneath.

  • Page 12: Opening The Main Cabinet

    1550 Inst Issue 6 05/09/06 9. Opening the Main Cabinet The control enclosure across the front of the machine is hinged from the right hand side. There is a single handwheel (1) in Diagram 7 below) which must be unscrewed.

  • Page 13: Changing A Cutter Hub

    1550 Inst Issue 6 05/09/06 10. Changing a Cutter Hub Access the cutter area as shown in Section 9 above. Remove the 3 screws [(1) in Diagram 9 below] which secure the cutter cover. Lift the cutter cover off the machine.
  • Page 14 1550 Inst Issue 6 05/09/06 Screw on the cutter shield, and using a 4mm Hexagon Key tighten the central grub screw until the cutter hub is released from its taper. Remove the old cutter hub. Clean the taper on the spindle, and the tapered bore of the new hub.

  • Page 15: Cutting Principles

    Issue 6 05/09/06 11. Cutting Principles The 1550 removes 0.75mm of material from the stock being polished. When dealing with these small amounts, machine adjustments become imperative to optimum performance. Below is a description of the machine adjustments which are available.

  • Page 16: Transport Parallelism

    1550 Inst Issue 6 05/09/06 Transport Parallelism The transport pressure plates are spring loaded to accommodate material thicknesses from 3-50mm (0.125”-2”). The plates are mounted on linear guides, and therefore will not twist to conform to the material. For this reason, it is important to ensure that the pressure plates are parallel, so that the material being polished is gripped all the way through the polishing operation.

  • Page 17: Transport Pressure

    1550 Inst Issue 6 05/09/06 Transport Pressure Material to be polished is loaded vertically onto the infeed track. The transport system grips the material and transports it across the cutter (arrow 1 in Diagram 13 below). The transport also applies a gentle downward pressure (arrow 2 in Diagram 13 below) This ensures that the material is supported by the smooth surfaces of the feed tracks.

  • Page 18: Feed Track Alignment

    1550 Inst Issue 6 05/09/06 Feed Track Alignment The machine removes 0.75mm of material per cut. If the feed tracks were level, the material would be unsupported once it was polished. This would cause the material to fall onto the outfeed track as it left the transport and could mark the finish on longer pieces.

  • Page 19: Cutter Cover

    1550 Inst Issue 6 05/09/06 Cutter Cover The cutter cover extends the feed tracks over the cutter aperture, supporting the material, which improves finish quality. The left hand section (1 on Diagram 15 below) is level with the infeed track. The central and right hand sections (2 on Diagram 15 below) are level with the outfeed track.

  • Page 20: Spindle Tilt

    1550 Inst Issue 6 05/09/06 Spindle Tilt The cutting action takes place on the left hand side of the cutter revolution. To avoid leaving “backswipes”, or witness marks from the right hand side of the cutter, the spindle is tilted to 0.14°. This leaves approximately 0.3mm of clearance between the cutter and the material on the right hand side of the cutter revolution.

  • Page 21: Effect Of Cutter Height - Cutter Too Low

    1550 Inst Issue 6 05/09/06 Effect of Cutter Height – Cutter Too Low Should the cutter be too low, the following will occur: The front corner of the material will hit the centre island of the cutter cover after polishing. This will leave a mark in the finish. (1) in Diagram 17 below.

  • Page 22: Effect Of Cutter Height - Cutter Too High

    1550 Inst Issue 6 05/09/06 Effect of Cutter Height – Cutter Too High Should the cutter be too high, the following will occur: The machine will remove too much material from the edge being polished. This will leave the polished material above the outfeed track level.

  • Page 23: Effect Of Panel Thickness On Cutter Height

    1550 Inst Issue 6 05/09/06 Effect of Panel Thickness on Cutter Height While the cutter should be level with the outfeed track, this position will vary depending upon the thickness of material being polished. This is because of the spindle tilt as described above.

  • Page 24: Cutter Height Adjustment

    1550 Inst Issue 6 05/09/06 12. Cutter Height Adjustment The Cutter Height assembly comprises the following elements: Clamping Handle [(1) in Diagram 20 below]. This clamps the spindle. Move to the left to unclamp. Move to the right to clamp. Note that firm pressure must be applied to clamp the spindle.
  • Page 25 1550 Inst Issue 6 05/09/06 The procedure for adjusting the cutter height is as follows: Switch the machine off at the Mains I-O switch. Ensure that all motors have stopped. Open the main cabinet Unclamp the spindle. Remove the index pin, and place into its new hole.

  • Page 26: Maintenance

    The only regular maintenance which is required is the changing of cutter hubs. Periodically the transport belts may require servicing, please refer to the separate Service Manual for information regarding this. Should there be any queries regarding the 1550 Diamond Polisher, please contact the manufacturer or their nominated Distributor.
