The OERLIKON K4a is a manual gear hobbing machine designed for precision gear manufacturing. It supports a wide range of gear modules, with a largest module of 30.0 and a smallest module of 2.0, allowing for versatile gear production. The machine accommodates a maximum gear ratio of 1:8, enabling the machining of various gear sizes. It can handle gear pitch diameters up to 1250 mm at a 1:1 ratio and up to 1600 mm at a 1:8 ratio. The maximum number of teeth it can process is 300, with minimum teeth counts of 20 at a 1:1 ratio and 10 at a 1:8 ratio. The maximum tooth width supported is 300 mm. The brushing heads have a stroke range from 50 mm minimum to 320 mm maximum, providing flexibility in finishing operations. The base gear radius ranges from a minimum of 170 mm to a maximum of 950 mm. The machine allows for a cone angle of inclination between 7° and 83°, with addendum and dedendum angles up to 6°30 and 7°30 respectively. The distance of the faceplate from the top of the cone ranges from 170 mm to 950 mm. Visually, the machine is painted green and features a large handwheel on the side for manual operation. The machine bed holds various metal parts and tooling, along with pallets containing gear components and a cardboard box. A cloth is tied around the handwheel, possibly for protection or cleaning. The machine shows signs of use with some wear marks and dirt on its surfaces, indicating it has been utilized in an industrial workshop environment. The table includes T-slots below a large circular cover, which supports versatile mounting and fixturing options. This machine is suitable for workshops requiring manual gear hobbing capabilities with a broad range of gear sizes and specifications.
