PRE-TREATMENT, SURFACE PREPARATION, DEGREASING & CLEANING Linked Cleaning and mass fi nishing solution for brake components Continuous processing of parts that must be glued together LUMAG, a well-known Polish brake pad manufacturer, presented Rösler with the challenge of fi nishing a surface in order to maximize its adhesion characteristics for a subsequent bonding stage. Rösler offered a solution for de-oiling and surface fi nishing of brake pad carrier plates directly linked to a punch press. LUMAG Sp. z o.o., founded by Mr. Marek Zak in 1988, is specialized in the production of brake pads for drum and disk brakes for commercial vehicles. For the latter the company, located in Budzyn, Poland, developed its own manufacturing technology resulting in significant quality improvements. In addition, LUMAG develops, produces and sells brake pads for passenger cars and motorbikes under the trade name Breck. De-oiling, deburring and surface roughening As a result of changing the production method for the brake pad carrier plates, from casting to stamping, LUMAG decided to install a new in-house manufacturing line for these products. This included a solution for de-oiling, deburring and surface roughening of the stamped carrier plates with lengths of 210-250 mm and widths between 90-110 mm. It should be noted that the components have a slit or drilled hole for placing a sensor, which monitors the wear of the brake pad. These steps were intended to ensure that the delicate stampings provide optimum adhesion characteristics for the following bonding of the brake pads. Another requirement presented by the customer was to directly link the finishing equipment with the punch press, maintain extremely gentle processing and complete automation of the cleaning (de-oiling) and mass finishing stages in continuous feed operation. LUMAG decided to partner with Rösler for The fully automatic de-oiling/washing and mass fi nishing system is directly linked to the punch press and allows for continuous feed operation. The only manual operation is the replacement of the full transport bins every few hours. 50 OCTOBER 2019 read online: www.surfaceworld.com
