With the Trotec rotary engraving attachment, you can use your Speedy laser engraver to process tumblers, cups, vases and bottles of various sizes and diameters.
When the rotary engraving attachment is inserted, the axis movement in the Y direction is replaced by a rotary movement. With the special roll attachment, you can even process objects with large or small openings that do not fit into the cones of the standard configuration.
First, move the table of the laser machine to its lowermost position. On the Speedy 360 and Speedy 400, the front door can also be opened, simplifying insertion. Now switch off the laser. To install and remove the rotary engraving attachment, the laser must be switched off. This ensures safe handling in the processing area.
Now insert the rotary engraving attachment into your laser, and fix it with the clamps on the rulers of the ferromagnetic engraving table or vacuum table. Then connect the device via the connecting cable on the inside of your machine. Now switch on the laser again. This starts the homing process of the laser, and the rotary engraving attachment automatically rotates to the 0° position.
®. Next, go to the JobControl® Print window, check the "Rotary Attachment" option, and enter the height of your graphic and the diameter of the workpiece on the right-hand side. Measure the diameter at the point where you want to laser engrave your workpiece. This causes the JobControl® software to calculate the circumference of the object and automatically adapt the job size. Using these settings, the software also calculates the angle for rotation during the engraving. The height of the plate in JobControl® thus corresponds to the circumference of the workpiece.
Then select the desired parameter and send the job.
Select “Minimize to Job Size” to facilitate the positioning of the job in JobControl®.
Now clamp the desired workpiece into the rotary engraving attachment and fix it with springs. Make sure the workpiece is not clamped too tightly or too loosely. This will allow quick exchange of the workpiece to be engraved as well.
If the workpiece is not cylindrical but conical, as wine glasses are, using the Speedy 300, 360 and 400, you can align the engraving area parallel to the working table using the rocker lever on the left side. In addition, the cones are height-adjustable on both sides in order to permit work with various workpiece diameters.
If you want to engrave glasses or cups with handles, they must be placed so that the handle is not rotated into the engraving field. First, move the Y axis (rotary motion) to the very top. Clamp the workpiece so that the handle is slightly above the laser beam. Since the workpiece is rotated backwards for the laser process, there is no risk of collision with the laser head.
For safety, detach the nozzle in order to avoid collision with the rotary engraving attachment. Then focus onto the engraving area of the workpiece.
Depending on the machine, workpieces of various sizes can be engraved. For more information, access our online overview What is the maximum dimension for rotary engraving attachments?
