Precision Honing Machines
Small bore diameters often place different demands on the production technology as large ones. Problems such as a less favorable length/diameter ratio of the bore and less available space have to be solved.
Due to the customer requirements we have continuously improved our lifehone machine. Market-proven functional modules have been included in a modular design - the result: a cost-efficient machine, short delivery times and functionally advanced components.
Whether constructed as a multi-spindle transfer solution for mass production, or as single-spindle design for small batches - highly accurate parts with honing diameters up to 90 mm can be processed optimally with the appropriate machine. Characterized by ease of use and high performance, you will find the right solution for your requirements and process conditions.
We select the appropriate honing unit based on workpiece design and the required speed dynamics. The Gehring honing control allows for precision controlled stroke speeds and reversal precisions. For the stroke drive you can choose between a ball screw or a linear motor.
The user-friendly and clear graphic interface of the Gehring operator panel (GOP) as well as the program assistant eases machine operation significantly. After entering a few relevant parameters about the component, material and tool, the process and stock removal can be defined, and honing can be started once the tool has been positioned. The stroke position and all other relevant parameters for machining the component are automatically calculated.
The bore diameter and the conicity will determined by a pneumatic gauging system and graphically shown on the display of the honing control. Depending on customers request, in-process as well as pre and post gauging systems can be installed.
It is possible to integrate a brushing process to deburr slight burrs at the edges of holes or cross holes produced by honing. An option is also available for the integrated cleaning of the workpiece by centrifugal application or air blowoff station.

The single spindle version of the Lifehone series is impressive with its compact design and small footprint. Depending on the machining task and the batch size, this type of machine can be equipped with a fixed or rotary table and up to 4 stations.

Compared to the single spindle honing center, this option is 60 cm wider. The two spindles allow for a two stage honing process, and therefore shorter honing times and honing of more material. Rotary tables with maximum of 8 stations offer place for gauging operations or brushing operations.

This machine is especially designed for the needs of machining of transmission parts, for examples gears. The integrated gripper transport offers the possibility to cycle gears with different diameters. Furthermore, the user only needs one fixture below the two spindles.

Alternatively equipped with a six or eight sided inner column, you can fix up to 7 honing spindles. With this feature, we can assure short cycle times and multistep processes. Pre and post gauging stations are fixed on the opposite side to optimize the interior space of the machine in the best way possible.

Our three-spindle lifehone hones the workpieces horizontally. The machine is loaded via a handling system from the pallet. In general, the number of workpieces per pallet is between 5 to 10 pinion gears. The advantage of this pallet method is the shortened processing time per workpiece.

The transfer design of the lifehone series is usually recommended for solutions with four or more spindles. Depending upon the desired cycle times and honing process the machine is designed with the correct number of spindles. This design also makes sense when different bore diameters must be processed on one workpiece.

The super finishing of high-precision components depends on the perfect coordination of all influencing factors to the honing process such as the honing tool, abrasives, fixtures, feeding and gauging systems. All of these elements must be perfectly matched to one another to achieve an optimal result. We supply you with the complete package from the abrasives to the machine, so that you always receive the perfect solution for your application.
The single-stone L series tooling system is especially designed for honing high-precision bores with a diameter range of 3–15 mm. The tool joint and base are assembled by means of “thermal shrinkage”. This joint features high concentric accuracy (≤ 5 μm) as well as the capability to transfer high torque and axial forces.
Besides tools and abrasives, we offer you various automation concepts - Automatic loading or unloading with robot or gantry are possible.
