Schmidt & Heinzmann (Bruchsal, Germany) highlights its newly developed deburring cell, an extension of the company’s product portfolio, which is said to cover almost the entire manufacturing process for composite materials, from the manufacture of semi-finished material, through the cutting and stacking of the individual layers, to press automation.

The deburring cell was developed so as to be directly integrated into the press automation. After pressing and cooling, the component is automatically fed into the deburring cell, reducing the logistical effort involved in component manufacture. Emissions are also significantly reduced by the housing of the cell and its intelligent extraction and dust removal, the company notes, and an automatic quick changer for tools increases the availability of the entire line.

Schmidt & Heinzmann also offers economical and efficient solutions for the processing of dry fibers via an intelligent nesting process which enables optimal cutting pattern for reduced material waste. When using several materials within one stack, Schmidt & Heinzmann relies on its Multiple Cutter Concept (using a polygon knife, round knife, ultrasonic knife and so on), meaning there is one cutter for each material, shortening cycle time and increasing process reliability. The precise stacking of single-layer cuts is made by a variable gripper device which holds the cuts with vacuum, needles or finger modules. Afterwards, the stacks are permanently fixed by ultrasonic welding for further transport or can be processed into preforms by using a preforming center from Schmidt & Heinzmann. Labeling of the stack or preform as well as camera-based quality control are also possible.

According to the company, different sensors ensure a stable process both during cutting and stacking and adjust defined process parameters independently, if necessary. The control-integrated production planner monitors the entire process and thus enables optimal cutting, handling and stacking sequences.
