The four-axis turning cell with two turrets, NC-quill and steady rest is the ideal basic setup for shaft machining. Complex turning jobs can be combined with simple drilling and milling operations without the need for reclamping, and with maximum precision whether in small lots or large series.
The sophisticated component handling lends itself to a wide application spectrum. The system can be expanded to add further technology or to increase lot sizes.
When both ends of a shaft require machining using conventional production cells, it is always necessary to reclamp the workpiece. When geometries have mutual reference points, it is often impossible to keep the process stably under control, despite complex orientation and expensive clamping technology.
Our F machine has a sliding centre drive which eliminates this potential for error, because it enables both ends to be machined without reclamping. Using the optional second sliding vice, very short protruding lengths can be realised even for components of up to 800mm – with process reliability and patented engineering.
The combination of turning and milling in a swivelling B axis opens up a wide range of applications, for example when machining camshafts. The integrated tool changer further enhances the degree of variability available.
When it comes to more complex milling operations, we also offer a fixed milling axis, with a performance and rigidity dimensioned for deep drive slots.
When it comes to soft or hard machining, our double grinding cell can do both. In combination with an end facing machine, vertical turning cell or worm milling machine, the shaft line obtained is of a single piece and sets standards in terms of cost-effectiveness and process reliability.
The vertical worm milling machine is used for producing shafts for screw compressors, screw spindle pumps, extruder screws, rotating spindles, steering spindles, screw conveyors and drilling tools. The high rate of material removal results in a 50% reduction in unit costs compared to grinding.
The combination of a worm milling machine with a four-axis vertical turning cell represents an integrated process.
Guaranteeing process reliability in production when performing hobbing operations requires a wide knowledge of hobbing technology. Which is why Schuster-Maschinenbau has entered into a close cooperation with Gleason Pfauter Maschinenfabrik GmbH, a company which specialises in the entire process, comprising such areas as dimensioning the milling unit, tool technology, and measuring procedures. Gleason Pfauter is also responsible for the sale of this machine.
The availability of a production line is only as high as the availability of the weakest sub-process. On the basis of an FMEA, Schuster-Maschinenbau has developed a stable end facing unit which replaces the low performance and service life of powered tool holders with considerably more powerful individual milling spindles. This greatly benefits the cycle times and availability of the entire production line.
