Gühring 100 15 Flute Grinder
Serial Number: 1399
Technical Evaluation of the Gühring 100
Flute Grinding Machine (Serial No. 1399)
1. Technical Evaluation Overview
The Gühring 100 is a flute grinding machine intended for manufacturing or regrinding flutes on cutting tools such as drills, end mills, or similar rotary tools. Beyond the model designation (100) and serial number 1399, no technical specifications are provided regarding tool diameter range, flute count capability, axis configuration, grinding wheel size, control system, or automation level.
Due to the absence of these details, no quantitative assessment of capacity, accuracy, or productivity can be made based solely on the provided information.
2. What to Check Before Buying
Given the lack of specifications, inspection should focus on establishing the machine’s actual capabilities and condition. Mechanically, the grinding spindle should be checked for runout, vibration, and bearing noise. Slideways or linear axes should be evaluated for smooth travel, backlash, and wear.
The workholding system (collets, chucks, or arbors) should be identified and checked for compatibility with the tool diameters intended for use. Grinding wheel mounting, dressing systems (if present), and coolant delivery should be inspected for completeness and functionality.
If the machine is CNC- or NC-controlled, the control system type, software version, and parameter backups should be verified. For mechanically or cam-controlled versions, condition of cams, linkages, and feed mechanisms should be assessed. Availability of manuals and electrical or mechanical diagrams is particularly important when specifications are undocumented.
3. Typical Industrial Applications
Without assuming specific capacities, machines of this type are generally used for flute grinding on rotary cutting tools, supporting tool production or reconditioning operations. Typical applications may include drills, reamers, and end mills, provided tool size, flute geometry, and material requirements fall within the machine’s verified limits.
4. Common Risks in Used Machines
Common risks with used flute grinders include spindle wear, loss of geometric accuracy in slides, and deterioration of dressing or coolant systems. For older machines, obsolescence of control or electrical components and missing documentation can significantly impact usability. Incomplete tooling or missing machine-specific accessories may also restrict practical operation.
5. Maintenance and Service Considerations
Maintenance needs depend entirely on the machine’s actual design, usage history, and condition, none of which are specified. Routine attention should be given to spindle lubrication, slideway condition, and grinding wheel interfaces. Long-term service planning should consider availability of spare parts, technical documentation, and qualified service support for this specific Gühring model.
Final Note:
The information provided is insufficient to define the technical capabilities or condition of the Gühring 100 flute grinder. Critical details—such as grinding capacity, control system, axis configuration, and service history—should be verified through documentation review and on-machine inspection before any technical conclusions are drawn.
