KEL-VERA
The on-going consequent development has led to the introduction of this extremely compact machine which is based on a visionary modular concept. The new design of the hydrostatic guideways is meeting even the extremest requirements on universal as well as on production grinding.
Building-up on their experience of more than 15 years with hydrostatic guideways KELLENBERGER is launching a completely new range of machines. The objective rigorously striven for had been to develop a compact machine which can be used for the grinding of any kind of components with a length of up to 400 mm.
The concept is based on platforms for the table slide and wheelhead supports, and also for applications where the table slide is the direct starting basis. The new machine models are offered in their standard configuration. Application- and customers-specific versions, however, are also available. The new very rigid hydrostatic guideways provide the basis for higher performance and dynamics in the X- and Z-axes. Further, the productivity and precision on unround grinding are significantly enhanced.
As an option automatic loading and unloading systems, integrated into the machines, can also be delivered.

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.

• Undercuts
• Flutes
• Tapers
• Chamfers

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.

QUICKPOINT's great advantage: This technology can be used for a wide range of applications in combination and combines this with extremely high productivity. Compared with conventional OD grinding - especially when grinding Tungsten Carbide - the QUICKPOINT method can
increase productivity by up to 600%!
QUICKPOINT grinding is a high-speed “peel grinding” process based on point contact between grinding wheel and workpiece. The QUICKPOINT process requires highly
wear resistant CBN or diamond grinding wheels which are typically only a couple of millimeters wide. Tilting the abrasive wheel to the horizontal workpiece axis creates a
relief angle that reduces the contact zone between abrasive wheel and workpiece from a contact line to a contact point.

The JUCAM series unround grinding machines from JUNKER are a versatile solution for complete machining of camshafts. All cam contours are covered:
• cylindrical
• concave/convex
• with/without chamfers
• with/without radius
• with tangent
• polygon/elliptic
Depending on the type of machining and the production quantity you need, JUNKER designs custom platforms and wheelheads and installs them on your JUCAM machines.
Cams, bearings, ends, thrust bearing shoulders, and camshaft adjustment seats can be ground in one clamping by JUCAM unround grinding machines. The use of
CBN grinding wheels makes rough grinding possible as well as precise finish grinding. These machines are not only used in the automotive industry but also in the textile
and pump industry as well as in cutting tools and gun drills.
