Mapal already offers a wide range of innovative machining solutions for manufacturing individual parts and components in electric vehicles. However, the challenge is an ongoing one that Mapal is continuing to meet. High precision for large diameters using ultralight tools One of the core challenges in electrified automotive powertrains is the high-precision machining of the main bore in the stator housing. Presenting a challenge for the tool and machine, all other steps in the production of the stator housing can be carried out on machines with a HSK A63 spindle configuration. However, in most instances the main stator bore requires machining with HSK A100 spindle. This is down to two factors: firstly, the high cutting torque requirements of up to 500Nm; and secondly, the maximum permissible tool weight and tilting moment. Cost-effective manufacturing with short cycle-times calls for a solution whereby complete machining can be carried out on a single machine with small spindle connections. This is because these machines are characterised by their high spindle speeds, lower investment and operating…
