16 2.1 Product - overall view MiniCutter Design and functions The laser head is used for the distance-controlled laser cutting of metals using fibre-coupled lasers. The laser head can be fitted to robot arms, multi-axis laser machines and other positioning systems. It is precisely engineered, rugged, service-friendly and can be adjusted easily. All media connections are located on the laser head. The laser head includes capacitive distance sensors that constantly record the standoff distance between the nozzle (nozzle electrode) and the workpiece. The system electronics analyses the sensor signal that is used to control a linear drive. Fibre plug-in connection (collimator) Laser beam position Focusing lens Focal position (adjustment module) Protective window cartridge Cutting gas The collimator is fitted firmly to the laser head and includes a fibre socket (QBH) and a collimating module (collimating lens with f C 75 focal length). The laser beam position adjustment device is integrated in the collimating module. Two Allen (socket) head screws (SW2) are used for centring the beam. The horizontal adjustment range is ±1.0 mm. Lenses with focal lengths from F75, F100, F125 to F150 can be used. The maximum clear optical diameter (clear aperture) is 20 mm. The vertical adjustment range lies between -4 and +4 mm for all focal lengths. The focal position is set using a large scaled dial (graduation of 0.25 mm) and an Allen key (size 4). The protective window cartridge (secured with two screws) is located below the focusing lens. The protective window (OG) is pressure-proof and can withstand maximum laser head pressure. The laser head can be operated at a cutting gas pressure of up to 25 bar (2.5 MPa). The cutting gas also cools the protective window. Cutting gas quality in compliance with ISO :2010; Solid particles - Class 2, Water - Class 4, Oil - Class 3 (see Table 7-2, page 7-41). The purer the cutting gas is the longer the protective window's life will be. Sensor insert, nozzle (nozzle electrode) The sensor insert (SE) is fitted firmly to the laser head. The nozzle (DE) is screwed into the sensor insert and can be replaced easily if worn. Precitec nozzles and sensor inserts are very precisely engineered. Because of the minimum concentricity tolerance any re-adjustment work can be reduced or avoided when replacing these parts. Please refer to Chapter 7.2 "Parts available", page 7-43 for the nozzle (DE) diameters that can be supplied. Fixing to the machine Four threaded holes M5x0.8 (9 mm deep) at the back of the laser head are used for fixing it to the machine. Two pin holes ø2.5 F7 (6 mm deep) are used to position the unit precisely and in such a way that this position can be reproduced. 2-8 Precitec GmbH & Co. KG EN 11/2014 D

17 2 Product description Distance controller Distance sensor system (Lasermatic ) Z For distance-controlled cutting, the laser head is equipped with the capacitive Lasermatic Z distance sensor system. Together with the other control loop components the system guarantees a constant standoff distance (focal position) between the nozzle electrode and the workpiece during laser beam cutting if there are no edges or large workpiece surface bulges in the sensor's scanning range. The MCX connection for the distance sensor system is located on the laser head (sensor cable, max. 20 m) Protective equipment Collision detection Protective cap Protective window When Precitec analysing electronics are used, an electronic collision signal is emitted when the sensor insert or the nozzle contacts the machine mass. The signal either stops the drive or enables the laser head to take evasive action. A protective cap is fitted between the nozzle electrode (DE) and the sensor insert (SE). It prevents any dirt from getting into the sensor insert. The protective window (OG) can be replaced or cleaned easily if it is soiled. This neither affects lens nor the laser head adjustment.

35 4 Commissioning Two adjusting screws (1, 2) are used to centre the beam position. Adjustment range: ±1.0 mm Tool: Allen key (size 4) If the machine manufacturer does not prescribe a different procedure, we suggest that you follow the steps described below: 1. Screw in a nozzle with a large nozzle opening. The nozzle opening should be considerably larger than the laser beam diameter at the nozzle opening. If the nozzle is too small for the nozzle opening, the nozzle can be removed. 2. Glue the sample under the nozzle. Caution laser beam - Wear laser goggles! During commissioning the laser machine may operate in laser class 4: The laser beam may cause eye damage. Do not look directly at the laser beam even using optical instruments. Use laser goggles complying with DIN EN 207 and BGV B2. 3. Trigger a low-power laser pulse and judge the penetration in the sample. The penetration must be round and in the centre of the nozzle opening. If not, the lens must be centred. 4. Centre/align the beam position using the adjusting screws (1, 2) on the laser head. Attention: The maximum adjustment range is ±1.0 mm. 5. Use a new sample. Trigger a low-power laser pulse and judge the penetration in the sample again. The penetration must be round and in the centre of the nozzle opening. Repeat the procedure from step 2 until the laser beam is in the middle of the nozzle opening. When the laser beam is in the middle of the nozzle opening, a nozzle with a smaller opening should be screwed into the sensor insert. Then repeat step 2 until the laser beam is in the middle of the nozzle opening again. When the laser beam has been adjusted, the laser beam must be in the centre of the nozzle (nozzle with the correct opening diameter for the cutting process). To avoid any damage, do not obstruct the laser beam. D Precitec GmbH & Co. KG EN 11/

36 4.2 Adjusting the laser beam MiniCutter Setting the focal position When adjusting the focal position, the system must not be under pressure (no cutting gas) and the distance controller must be switched off. 1 (size 2) 2 4 mm +4 mm (size 4) 1mm 580-LCfl-09 Fig. 4-2 Commissioning: Laser beam - Focal position 1 Clamping screw (size 2) (adjusting screw) 2 Adjusting screw, vertical adjustment Changing the focal position Use the adjusting screw (2) to adjust the head vertically. The adjustment range can be read on the scale. Modify the focal position. Loosen the clamping screw (size 2) (1). Turn the adjusting screw (2) using the Allen key (size 4) and centre the laser head's focal position correctly. Note: When the focal position has been changed, secure the adjusting screw with the clamping screw (1). Adjustment range Adjustment range: +4 to -4 mm (all focal lengths) (scaled dial with 0.25-mm graduation) Nominal focal position: 1 mm in front of the nozzle tip (view from the outside onto the nozzle tip) The zero mark on the scaled dial stands for the lens' theoretical zero position with a focal point of 1 mm below the nozzle (DE). Typically, focusing lenses are manufactured with a maximum nominal focal length tolerance of ± 1% (according to the manufacturer's specifications). As a result, the adjustment range can be limited. The focal position can thus vary depending on the lens. This must be taken into consideration when carrying out any adjustment Precitec GmbH & Co. KG EN 11/2014 D

37 4 Commissioning Setting the focal position If the machine manufacturer does not prescribe a different procedure, we suggest that you follow the steps described below: 1. Put a sample under the laser head (nozzle). Caution laser beam - Wear laser goggles! During commissioning the laser machine may operate in laser class 4: The laser beam may cause eye damage. Do not look directly at the laser beam even using optical instruments. Use laser goggles complying with DIN EN 207 and BGV B2. 2. Trigger a (low-power) laser pulse and judge the penetration in the sample. 3. Change the nozzle standoff distance to find the smallest penetration. 4. For the smallest penetration determine the standoff distance (d) between the nozzle and the sample surface. 5. If the measured standoff distance (d) does not match the desired standoff distance (Zn), you must adjust the lens by the difference in the direction of the linear drive. Loosen the clamping screw (SW2) (1). Turn the adjusting screw using the Allen key (size 4) and centre the laser head's focal position correctly. When the focal position has been changed, secure the adjusting screw with the clamping screw (1) (see Fig. 4-2, page 4-28). Note down the setting (on the scale) for reference. Adjusting the scale reading (reference adjustment, optional) (size 2.5) LCfl-08 Fig. 4-3 Commissioning: Laser beam - Reference adjustment 3 Scaled dial (scale, 0.25-mm graduation) 4 Fixing screws (SW2.5) (2x) Scale Reference adjustment Loosen the fixing screws (4). The zero mark can then be calibrated to the new position. When adjustment is complete, secure the scaled dial again. D Precitec GmbH & Co. KG EN 11/

38 4.3 Checking the standoff distance MiniCutter 4.3 Checking the standoff distance When checking the standoff distance, the system must not be under pressure and the laser must be switched off. The standoff distance (nominal distance, Zn) is the distance between the tip of the sensor (nozzle/nozzle electrode) and the surface of the workpiece. Analysing electronics I/O 1 2 EG PLC Fig. 4-4 Commissioning: Laser beam - Standoff distance MiniCutter-Zn / EG-e BNC connection (1, label) 2 Sensor cable (max. 20 m) Use [NomClrNr] to select one of the predefined standoff distances Zn1 to Zn4. The selected standoff distance is the nominal value to be used by the adjust box (EG8110). The standoff distance can only be selected on the adjust box EG8110 if [PaSelct] is enabled. 1. Enable Automatic mode. 2. Select nominal distances (Zn) one after the other and follow the on-screen display. The actual distance and the standoff distance must match. 3. Check or measure the standoff distance (e.g. Zn1). Select the standoff distance, enable manual mode and measure the actual distance between the nozzle and the workpiece. Should the measured value deviate from the displayed standoff distance, calibration must be repeated with the correct characteristic curve. For detailed information on selecting and setting standoff (nominal) distances (Zn) using the analysing electronics, please refer to the separate Adjust Box EG8110 documentation Precitec GmbH & Co. KG EN 11/2014 D
