Hardinge Inc. introduces the new Kellenberger 100 (pictured) and Kellenberger 1000 Universal CNC grinding systems. These innovative systems improve the precision and productivity for the most demanding range of machining applications. The updated functional and user friendly design elements on both of these systems allow you to have the control and performance you require.
“These systems were made to satisfy the requirements of our customers. We took their feedback and from the rigid base to the hydrostatic guides on all axis, all the way to the new user interface on our controls we delivered two systems that will meet the most demanding of those requirements, and if Industry 4.0 is an important topic for you these machines are equipped with OPC UA communication gateways for secure external access, the machines are well prepared for the future.” Helmut Gaisberger, global product manager grinding.
The Kellenberger 100 is a new high-performance, economical grinder for any of universal grinding requirements. The machine is the combination of capabilities that are found in the VISTA and VITA machines, as well as the Tschudin T25, and the Jones & Shipman Ultramat CNC and Ultragrind 1000. It delivers a diverse of configuration options for a range of grinding operations for customers looking to optimize production costs for the machine and ensure an excellent price/performance ratio.
Customers can now get:
• New compact wheelhead design - The Kellenberger 100 has a new tandem grinding wheelhead in compact and collision free construction with the motor spindle. Reinforced casing for larger grinding wheel diameters for internal grinding. Choice of 10 wheelhead variations for the optimal layout of the machine based on the components to be processed.
• Increased productivity with higher grinding wheel drive power.
• Enhancing performance o Realize new dressing concept by extended travel of X and Z axes
• Greater Profile Accuracy with Redesigned Z-guideways.
• High precision B-axis with direct drive and absolute measuring system
• Increased accuracy for noncircular grinding with C-axis with direct drive.
The user-friendly and ergonomic design of the Kellenberger 100 machines with a new, intuitive operator guidance system on a touchscreen panel. The machines are equipped with the latest FANUC 31i CNC with 19" touchscreen, The User Interface is available in two different versions: BLUE Solution - the intuitive touch programming and RED Solution - the extended graphic programming.
The new Kellenberger 1000 is the next generation of the VARIA universal cylindrical grinding machine that has been the standard in high precision grinding for over 20 years. The Kellenberger 1000 offers advanced technology, design and features for high-precision production of prototypes and small and medium-size series.
Customer can now get:
• Genuine precision and productivity with hydrostatics – The Kellenberger 1000 features the newest generation of hydrostatic guideways for superb precision and productivity. They provide excellent damping, stick-slip-free operation, high rigidity, and a constant machine temperature, resulting in outstanding surface quality and more reliability without any friction loss and wear.
• Best in class for Taper-, Thread-, Profile- and out of Round Grinding
• Supreme Stability and Rigidity with Larger Workspace - In the new Kellenberger 1000, the machine table has been considerably extended, so it allows unmatched, optimal positioning of the grinding wheel and a larger travel distance, ready for a wider variety of machining options and application-specific configurations. With the reinforced machine bed, Kellenberger 1000 can now work with workpieces of up to 300 kg and larger heights of and distances between centers, offering consistently better performance.
• Flexibility with Unique machine concept - The Kellenberger 1000 is available with distances between centers of either 1,000 or 1,600 millimeters, and heights of centers of either 200/250 or 300 mm, as required. Travel on the X-axis and Z-axis has been extended. 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.
• More Operator Friendly and Reliable with Functional Machine Casing - The increased sheet metal thickness means even more process reliability, allowing larger internal grinding wheel diameter of up to 125mm.
• Compact and Maintenance-Friendly Elements such as the power supply, electrical cabinet, and a central connection point for lubricating coolant, water cooling system, and compressed air were all integrated into the casing. The Kellenberger 1000 is known for the compactness of the space it requires for setup.
• Optimized Energy Management Performance-optimized central cooling system for minimized thermal drift with the result in minor deviation on the workpiece.
Related Glossary Terms
- centers
centers
Cone-shaped pins that support a workpiece by one or two ends during machining. The centers fit into holes drilled in the workpiece ends. Centers that turn with the workpiece are called “live” centers; those that do not are called “dead” centers.
- computer numerical control ( CNC)
computer numerical control ( CNC)
Microprocessor-based controller dedicated to a machine tool that permits the creation or modification of parts. Programmed numerical control activates the machine’s servos and spindle drives and controls the various machining operations. See DNC, direct numerical control; NC, numerical control.
- coolant
coolant
Fluid that reduces temperature buildup at the tool/workpiece interface during machining. Normally takes the form of a liquid such as soluble or chemical mixtures (semisynthetic, synthetic) but can be pressurized air or other gas. Because of water’s ability to absorb great quantities of heat, it is widely used as a coolant and vehicle for various cutting compounds, with the water-to-compound ratio varying with the machining task. See cutting fluid; semisynthetic cutting fluid; soluble-oil cutting fluid; synthetic cutting fluid.
- cylindrical grinding
cylindrical grinding
Grinding operation in which the workpiece is rotated around a fixed axis while the grinding wheel is fed into the outside surface in controlled relation to the axis of rotation. The workpiece is usually cylindrical, but it may be tapered or curvilinear in profile. See centerless grinding; grinding.
- dressing
dressing
Removal of undesirable materials from “loaded” grinding wheels using a single- or multi-point diamond or other tool. The process also exposes unused, sharp abrasive points. See loading; truing.
- grinding
grinding
Machining operation in which material is removed from the workpiece by a powered abrasive wheel, stone, belt, paste, sheet, compound, slurry, etc. Takes various forms: surface grinding (creates flat and/or squared surfaces); cylindrical grinding (for external cylindrical and tapered shapes, fillets, undercuts, etc.); centerless grinding; chamfering; thread and form grinding; tool and cutter grinding; offhand grinding; lapping and polishing (grinding with extremely fine grits to create ultrasmooth surfaces); honing; and disc grinding.
- grinding machine
grinding machine
Powers a grinding wheel or other abrasive tool for the purpose of removing metal and finishing workpieces to close tolerances. Provides smooth, square, parallel and accurate workpiece surfaces. When ultrasmooth surfaces and finishes on the order of microns are required, lapping and honing machines (precision grinders that run abrasives with extremely fine, uniform grits) are used. In its “finishing” role, the grinder is perhaps the most widely used machine tool. Various styles are available: bench and pedestal grinders for sharpening lathe bits and drills; surface grinders for producing square, parallel, smooth and accurate parts; cylindrical and centerless grinders; center-hole grinders; form grinders; facemill and endmill grinders; gear-cutting grinders; jig grinders; abrasive belt (backstand, swing-frame, belt-roll) grinders; tool and cutter grinders for sharpening and resharpening cutting tools; carbide grinders; hand-held die grinders; and abrasive cutoff saws.
- grinding wheel
grinding wheel
Wheel formed from abrasive material mixed in a suitable matrix. Takes a variety of shapes but falls into two basic categories: one that cuts on its periphery, as in reciprocating grinding, and one that cuts on its side or face, as in tool and cutter grinding.
