As a system supplier to the automotive industry, HELLER develops manufacturing solutions for the flexible complete machining of crankshafts and camshafts. We are one of the few suppliers worldwide that has extensive experience across the entire process chain. The HELLER RFK/DRZ/MCC 15/RFN production systems and various machining centres offer the core processes for pre-machining crankshafts and camshafts. These efficient custom machines can be equipped as a stand-alone solution or as interlinked individual machines within a manufacturing system. Key facts comprehensive HELLER expertise across the entire process chain customised process engineering matched to the requirements concerned responsible overall project management highly productive complete solutions using: external or internal milling, turn-chasing, milling, drilling and thread cutting use of other technologies, or also in combination External milling of crankshafts External milling is a flexible and productive method used primarily in the mass production of small to medium-sized crankshafts. The RFK crankshaft production systems from HELLER are for machining concentric and eccentric bearing points, cheek faces and cheek outer diameters as well as special contours in a highly productive manner – often in just one set-up. tool generates the cutting speed workpiece generates the feed rate use of external cutters cutter diameter can also be used for most hollow cam profiles. tool profile is designed according to the profile to be milled for the machining of crankpins, 2 interpolating NC axes are used which are positioned eccentrically to the workpiece centre and/or the concentric main bearings of crankshafts
