FAQ / Details

Which items of mine are suitable for honing?

The following are typical examples of items whose quality can be improved through honing or are ideal for reworking:

  • Bearing bushes
  • Piston pin bushes
  • Planetary gears
  • Toothed wheels
  • Sprockets
  • Rotors
  • Gear wheels
  • Camshaft bearings
  • Valve blocks
  • Pressure cylinders
  • Connecting rods
  • Piston bearing surfaces
  • Main bearing bores
  • Brake and clutch cylinders
  • Rockers
  • Control housings
  • Pulleys
  • Spring plates
  • Eccentrics
  • Hydraulic parts

What can I achieve through honing?

Correcting cylindrical forms and positional tolerances using honing delivers many results:

  • Material removal
  • Increased friction coefficients
  • Modified peripheral zone properties
  • Improved surface quality
  • Increased contact areas
  • Precision reworking
  • Corrected bore positions

Creating functions for gliding, sealing and/or guiding

Our end-to-end quality assurance process guarantees the best results, specifically:

  • Inward goods inspection: when the workpieces arrive, unit quantities are reviewed based on the consignment notes. Measuring tools and devices are selected to suit the product and are set down in an inspection plan. A visual inspection is performed under a microscope.
  • Ongoing checks: various measuring tools are used during the honing process, including dial gauges, surface meters, limit plug gauges, bore gauges, nozzle plug gauges, form testers and a coordinate measuring machine.
  • Final checks: prior to washing and packing in our logistics area, workpieces are checked once again in our quality assurance area, depending on the quality requirements.
  • Approval for delivery and the customer-specific documentation

Which machines does Frankenstein Präzision work with?

We use special measuring devices for all parameters. These automatically align your workpieces through centring and levelling processes. Some of the devices we use:

Talyrond 290 and Talyrond 585 are form testers that enable us to perform analyses of roundness, linearity, parallel alignment, coaxiality and evenness.

The Talysurf 50 is a surface meter. We use this to measure the surfaces of your workpieces and identify any potential deviations.

The Contracer CV3000 is a profile measuring device that we can use to measure the edges of your workpiece by tracing the contours. This helps us to identify deviations such as the formation of burrs.

The Zeiss Contura G2 is a coordinate measuring machine that we use to check the shape and position measurements of your workpiece and identify any potential deviations. This measuring machine is suitable for larger drill holes.

You want to achieve the best possible surface quality, shape or positional tolerance. With Frankenstein Präzision, you can be sure your requirements will be met. We achieve the best results in the smallest areas:

  • Maximum accuracy guaranteed down to < 1 µm
  • Honing diameters of 3 – 90 mm
  • Workpiece lengths up to 100 mm (standard)
  • Workpiece lengths up to 200 mm (special tools)
  • Roundness ≤ 0.5 µm
  • Cylindricality ≤ 2 µm
  • Surface Rz ≤ 1.5 µm
  • Diameter tolerance ≤ 1.5 µm
  • Linearity ≤ 0.5 µm
  • Angular position ≤ 3 µm
  • Parallel alignment < 3 µm
  • Squareness < 3 µm
  • Axial runout < 5 µm
