Comprehensive grinding solutions on offer from Hardinge Grinding Group at Grindtec

Kellenberger, the Swiss manufacturer of high precision grinding machines, is representing the interests of the international Hardinge Grinding Group at the Grindtec exhibition with a comprehensive exhibit on Stand 5129 in Hall 5.

Featured on the stand will be four machines from Group companies – the newly introduced Kellenberger 100 concept that can be tailored to meet specific customer requirements, the highly popular Kellenberger VARIA 1000 universal cylindrical machine, the latest Hauser 2000 jig grinder with its new frame design and a Hardinge Super-Precision Quest GT 27 which offers turning and grinding in a single set up.


The latest Kellenberger 100 series platform sees the high-performance, economical grinder segment in the Group’s portfolio being completely overhauled to meet a range of future manufacturing demands. Based on a modular design, it incorporates key elements of Kellenberger’s Vista and Vita model ranges, the Jones & Shipman Ultramat CNC and Ultragrind 1000 and the Tschudin T25, aspects of which have been integrated into the new range. 

Kellenberger has developed a platform on which diverse machine concepts can be realised in line with customer budgets and performance expectations. In effect, offering the most diverse range of configurations to achieve the widest range of grinding operations at a highly competitive price.

In terms of functionality the new 100 platform far exceeds the capabilities of many existing grinding machines. Because of its modular configuration, assembly of 100 series machines is simplified making it possible to optimize manufacturing costs for the machine and ensure an excellent price/performance ratio for the purchaser.  Numerous ‘standard’ options can put the customer’s finishing touches on each individual machine.

The user-friendly and ergonomic design of the Kellenberger 100 machines also features a new, simple operator guidance system with an intuitive touchscreen panel. The machines are equipped with the latest Fanuc 31i CNC controls with 19″ touchscreen and a newly designed cycle programming or workpiece-related graphic programming is an option.

The machine featured at Grindtec will be the 1000mm between centres variant, the other option being a 600mm unit.  It will be equipped with a WeFlex automated load / unload system supplied by Wenger AG.  This is an option that can be fitted to any Kellenberger 100 derivative.

With more than 1000 Kel VARIA machines in use worldwide, the VARIA universal cylindrical grinding machine range epitomises the best in working and surface quality among Kellenberger’s range of products. It has consistently been upgraded throughout its 20 year life but now, with its larger work space, distinctly longer machine table and distance between centers of 1600 mm, it is equipped for a very wide range of machining possibilities.

Aimed at the demanding environments involved in high-precision production of prototypes and small and medium-size components, typical areas of use include machine construction, the production of tools and moulds, the fabrication of precision components for the automotive, electronics and aircraft industries and sub-contract shops with their wide variety of needs.

The VARIA is available with distances between centers of either 1000 or 1600 millimeters, and heights of centers of either 200/250 or 300 mm as required. More than 30 wheelhead variations with external and internal grinding spindles permit an array of machining possibilities and the right application-specific configuration at all times. 

The Hauser 2000 jig grinder is the new successor to the well-positioned H35-400 model, which set industry benchmarks in terms of precision and performance for jig grinders.

The 2000 is a universal jig grinder with proven technical features such as automatic taper grinding, automatic grinding tool changer (ATC) and automatic pallet changer (APC).  It not only meets the demand of the market for combined grinding and hard milling on a single jig grinder, but also enables further improvements in machining precision to meet future requirements.

The main technical feature is the dual-frame design, which significantly increases the rigidity of the grinder and therefore ensures even higher precision. In this box-type design, the machining head is positioned centrally within the machine frame, thus enabling machining forces to be optimally controlled.

Almost no transverse forces are created and as the tool machining point is located at the center of the machine, practically all thermal expansion effects are eliminated.

With higher dynamic axis movements and significantly greater rigidity, the Hauser 2000 gives the best possible conditions for finishing with hard precision milling.

Finally, the Hardinge Quest GT 27 SP creates a combination of `state-of-the-art` manufacturing – such as turning and grinding in one setup – with an automatic loading and unloading system, offering great potential to significantly reduced production costs.

With the Quest GT 27 SP CNC Turning and Grinding Centre, equipped with an optional integrated parts handling system, Hardinge offers an outstanding technical and economic solution.

The Quest GT 27 SP is a combined High Accuracy Turning & Grinding Centre, specially designed for the high precision manufacturing of complex components in a single set-up. This machine features a 10hp, 8,000rpm main spindle with 27mm bar capacity, upgradeable to 42mm if required.

As a new option the machine can now be equipped with an automatic flexible loading and unloading system.  This features twin belt conveyors with a compact and space saving 6-axis robot cell mounted above the machine. It has a workpiece specific three jaw double gripper system for workpiece handling.

The Hardinge Quest GT 27 SP TURN/GRIND is ideally suited for stand-alone hard turning, hard turning and grinding or simply grinding operations to produce complex and high precision components.

Surface finishes (turning) of 0.2µ and exacting part roundness of < 0.4µ can be achieved. A total variation on component diameter of < 3µ provides outstanding machining results equivalent to grinding.
