In precision, grinding efficiency and geometric capacity the 5-axis CORVUS CNC machine is way out in front. Key elements are a mechanical construction as solid as a rock, the FANUC 160-M8 control and the Schneeberger QUINTO software. Largely identical subassemblies in the five axes and standard modules from the Schneeberger programme guarantee robust quality. Technology packages taken for granted with Schneeberger include the double spindle for up to 6 grinding wheels, valve-controlled coolant for each wheel, 3D probe and loading robot.

Grinding machines of camshafts CBN of production.
Series GC is made up of very compact and very nimble machines equipped with grinding stones CBN and intended for the mass production of camshafts.
These new machines are a digest of technological innovations, space on the ground at summer reduces considerably thanks to a very compact structure.
Consequently the rigidity of the frame is increased, only three fulcrums are today necessary and ensure a stability out-par by minimizing the negative impact of the variations of the ground the wire of time.
The kinematics in advance of grinding stone is entirely hydrostatic, as well the screw in advance as the slides of the door grinds, to ensure an extreme precision of correction of the profiles and a very weak response time.
Beyond that, the longevity of these elements is geared down and the better controlled maintenance costs.
On the automation plan, machines GC embark series a standard CNC GC50 of manufacture TOYODA, or with the request a CNC Fanuc, always with an interface HMI.
Interface HMI of a great ergonomics gets cycles very simplified operators and easy programming, functions of detection of breakdown
and a monitoring of the state machine in real-time reduce the downtimes machine to just in the event of anomaly.
Thanks to a capacity of removal impressive matter and a circumferential speed of grinding stone of 120 Meters/Second, very short cycle times are obtained even under difficult conditions.

The ShaftGrind Series offers many advantages, for example in the field of
high-productivity CBN grinding solutions.
Plunge and longitudinal grinding and high-speed rough grinding (HSP grinding) are all used here. In terms of plunge and longitudinal grinding using CBN wheels, the solution featuring a inprocess measuring system offers a high degree of flexibility and extreme precision, even when
processing large components. The non-round package and the WOP-G programming system mean that processing involving both cylindrical and non-round grinding (concave and convex forms) on a single workpiece in a single clamping operation with a very high level of precision have become a reality. From just a few data, the WOP-G programming system defines harmonious speed profiles and thus constant cutting conditions.
The combination of the ShaftGrind Series with high-speed grinding (HSP grinding) allows a high level of productivity with small batch sizes and small families of components. The amount of retooling and adjusting work is minimised thanks to the use of standardised grinding tools and extremely simple workpiece synchronisation.

Centerless grinding involves the workpiece being simultaneously machined and guided on its generated surface. The line contact on a grinding wheel forms the grinding line, the workpiece lies flush with the regulating wheel and is held in place from below by a guide rail.
During grinding, the center of the workpiece lowers as its diameter is reduced through abrasion. This causes the workpiece to migrate towards the regulating wheel. JUNKER’s electronic control system compensates for this position change by tracking the grinding wheel so that precise machining is guaranteed at all times.
Centerless cylindrical grinding is also the ideal solution for workpieces that are difficult to hold due to their shape or small dimensions.
