Automatic coating machine CBC 200

CBC 200 HELLER coating modules are used for coating cylinder bores in crankcases using CBC technology (CylinderBoreCoating). The CBC thermal coating process, developed in cooperation with Daimler, is based on electric arc wire spraying and is the only process that can be used for higher production volumes. HELLER CBC, therefore, is expanding our process chain in crankcase production by a crucial operation. Systems as flexible as you like – as a bypass solution or a precisely tailored manufacturing concept. Key facts The benefits of HELLER CBC at a glance thermal coating process for cylinder bores based on electric arc wire spraying 4-stage process: roughening, coating, finish boring and honing coating of all cylinder faces with bore diameters from 70 to 150 mm reduced fuel and oil consumption thanks to 50 % lower friction coefficients between piston and cylinder size and weight saving with the motor: more compact crankcase design due to the absence of cast iron liners and shorter distance between the cylinder bores coating with the HELLER CBC 200 coating module CBC process integrated into every large series production facility – as a bypass solution or a complete process from HELLER The mechanical foundation of the CBC coating process is the adequate preparation of the cylinder bore. A number of different roughing technologies are available for producing different surface conditions. To achieve the quality required for the coating process carried out in the second step, it is vital to create a structured surface quality whilst guaranteeing a precisely defined bore centre.
