HELLER expands the process chain in crankcase manufacturing – comprising qualification, pre-machining and finish-machining – by the CBC CylinderBoreCoating process. CBC is a technology for the coating of cylinder bores of aluminium crankcases using electric arc wire spraying. For this new process, HELLER has developed the CBC 200 coating module.
2) Pre-machining including fineboring and roughing of cylinder surfaces on a HELLER MC 20 machining module
3) Heating of the crankcase
4) Coating of the cylinder surfaces without structural changes of the aluminium base material in the CBC 200 coating module
5) Precise finish-machining including hard fineboring on a HELLER MC 20 machining module and final „Spiegel-Honen“ (polishing by honing)
Coating speed: approx. 30 sec. per bore workpiece
Changing time: approx. 20 sec.
Burner and wire change time: approx. 180 sec.
Engine types: I3 to V12
By the end of 2016, 32 CBC 200 machining modules will have been delivered and installed. Until 2018, a total of 65 systems for the coating of 26 million cylinder bores worldwide will be in operation. (updated: November 2016)
