2 Technical specification LSM 22 MAIN FEATURES for diamond saw blades with diameters ranging from.25 mm manual linear table and built-on rotatory table for taking up the blanks automatic segment feeding by means of belt-type magazine additional manual axis for welding of drop segments on both sides exact segment positioning by means of solid centric gripper segment feeding with water cooled gripper jaws laser head with water cooled optic, fixed beam angle of 3 flying optic with 2 axes adjustable C-axis (height of focus point) with measuring water cooled support of blank additional blank cooling via air nozzles central operating panel and CNC-control protection in conformity to the CE regulations (macrolon) OPTIONS - E..: combination air dryer / activated carbon filter (required option) - E..2: resonator base cabinet incl. adjustment, water filter and water connections (required option for CO 2 laser) - E..3: additional workpiece carrier - E..4: software for twin segments - E..5: software for triple segments - E..6: software for tack welding Universal Beam Switch / Universal Beam Switch Controller - E.5: Universal Beam Switch UBS 2 - E.6: Universal Beam Switch Controller UBC The LSM 22 can be connected by beam switch UBS 2 and beam switch controller UBC to other laser welding machines. Consequently, both machines can be operated independently with just one laser source. The beam switch controller UBC guarantees a safe maintenance and setting-up of the non-producing machine. CO 2 laser - E.7.: CO 2 laser Rofin Sinar 2 kw or - E.7.2: CO 2 laser Rofin Sinar 2,5 kw - E.7.3: cooling unit for laser 5 Hz (required option) or - E.7.4: cooling unit for laser 6 Hz (required option) - E..7: connection to existing laser source - fiber laser as laser source on request LSM 22 page 2 of 4 V2926; sz

3 FUNCTIONING The blank is placed manually on the rotary table and clamped manually. Then with the first adjustment the blank is moved manually to its welding position by means of a linear axis. The position of the linear axis is indicated precisely by a position encoder. The alignment for the first tooth has to be done manually. The segments are fed by a belt-type magazine and put against the blank by means of a solid gripper. The laser head mounted on the CNC-controlled X-Y linear table welds the segment on the blank. The blank is rotated automatically to the next tooth, meanwhile the gripper places the next segment at disposal. The operator changes the blank manually. If the blank has the same dimensions, alignment for the first tooth is automatic. In order to weld drop segments the blank is moved manually out of the center via an additional axis. The alignment for the first tooth has to be done manually by the operator. Welding the first segment and rotation to the next tooth is automatic. The procedure of moving the additional axis out of the center can be done on both sides to permit welding on upper and bottom side of the blank.
