'Helix' – helical groove milling
The Schuster 'Helix' helical groove milling machine comprises three construction sizes with one or two spindles for diameters of up to 50mm and lengths of up to 1,350mm. Compared with standard solutions, this procedure offers considerable benefits in terms of process speed and helix angle (compared to spinning) or hard machining and contour variability (compared to rolling).
Manual loading machine – for safe and easy assembly of rock drills.
The heart of the finished, grooved rock drill is applied in the manual loading machine stage – this is the carbide cutter. Due to the large dimensions of the rock drill and the small lot size involved, this work sequence – assembling the carbide cutters – is performed with the aid of a special machine.
This tailor-made solution means that a manual workplace is both rational and ergonomic, i.e. there is no bottleneck in small work sequences and quality and safety remain at a uniformly high level.
The process of tumbling results in the smoothing and hardening of a metallic surface without chip removal, using rollers. Tumbling is a very fine machining process that subjects the edge layers of the component to plastic (permanent) deformation. Moreover, it is the only non-cutting production procedure which is able to achieve surfaces of this form. Tumbling involves the use of one or several rollers onto which a force (tumbling force) is applied perpendicularly to the running surface.
