GEHRING 630-1 LR CNC Vertical Honing Machine – Technical Evaluation (Year 2017)
1. Technical Evaluation Overview

The GEHRING 630-1 LR is a CNC vertical honing machine manufactured in 2017, configured with 3 controlled axes. Based strictly on the provided information, the machine is equipped with a HAINBUCH hexagonal collet sleeve with a diameter of Ø65 mm and utilizes VDI40 tool holders. A hydraulic holder for reduction bushings is included, indicating flexibility for adapting tooling diameters within the VDI40 system.

No numerical stroke values, spindle speeds, honing diameter ranges, or achievable surface/roundness specifications are provided. As such, the technical assessment is limited to configuration, tooling interfaces, and supplied accessories rather than performance metrics. The description positions the machine for precision honing applications, but all process capability parameters must be verified.

2. What to Check Before Buying

Given the absence of core performance specifications, inspection should focus on the following:

Mechanical and axis system:

Functional verification of all 3 CNC axes, including smoothness, repeatability, and positional accuracy.

Condition of vertical slideways and alignment relevant to honing straightness and cylindricity.

Integrity and condition of the HAINBUCH Ø65 mm collet sleeve, including clamping repeatability and wear.

Tooling and holders:

Condition and compatibility of VDI40 hydraulic toolholders, including the supplied Ø20 ISCAR holders and reduction bushings (20→13 mm and 20→14 mm).

Verification that the hydraulic holder for reduction bushings operates leak-free and maintains clamping pressure.

Inspection of MAPAL holders, brackets, and reamer plates for wear, completeness, and suitability for the intended honing tasks.

Coolant and auxiliaries:

Functional check of the internal coolant pickup, ensuring proper delivery and filtration.

Verification of all auxiliary items (drawbar adapter, unclamping tool, cables) for correct fit and operation.

CNC and electrical system:

Identification of the CNC control type and software version (not specified).

Availability of machine parameters, backups, and alarm history.

General condition of electrical cabinets and hydraulic components.

3. Typical Industrial Applications

Based strictly on the stated configuration and tooling interfaces, the GEHRING 630-1 LR is technically suitable for:

Precision internal honing operations requiring stable vertical alignment and controlled axial motion.

Finishing of cylindrical bores using VDI40-based tooling systems and hydraulic clamping solutions.

Applications where quick changeover and accurate workholding via HAINBUCH collet systems are required.

Specific bore diameter ranges, achievable tolerances, and production suitability cannot be determined from the provided data.

4. Common Risks in Used Machines

For used CNC vertical honing machines of this class, typical risks include:

Guideway or axis wear, affecting straightness and surface quality.

Hydraulic system issues, particularly in toolholders and clamping interfaces.

Tooling mismatches, where supplied holders may not align with intended bore sizes or processes.

Incomplete technical documentation, especially regarding CNC configuration and machine parameters.

5. Maintenance and Service Considerations

With no service history or maintenance data provided, only general considerations apply:

Regular inspection of axis systems, clamping interfaces, and hydraulic components is essential for maintaining honing accuracy.

Toolholders, reduction bushings, and collet systems should be checked for wear and proper sealing.

CNC parameters and machine data should be backed up prior to operation.

Any maintenance or refurbishment planning should rely on on-site inspection and functional testing rather than assumptions about service intervals or spare part availability.

Final Note:
The GEHRING 630-1 LR, as described, is a modern CNC vertical honing machine with a defined tooling interface and an extensive set of accessories. A complete technical evaluation requires verification of honing diameter range, stroke lengths, spindle characteristics, CNC control details, and achievable accuracy through direct inspection and testing.
