What is the definition of Honing?

Bore and surface honing are just one of the many state-of-the-art precision surfacing solutions offered by PSS Group. 

What are honing stones and tools? These are horizontal and vertical honing processes mostly used for finishing. Flat honing and single pass honing manufacturer.

Horizontal and vertical honing machines are metal abrading tools and the honing process utilizing hard tooling or honing stones and perishable abrasives stones for the correction of

  • Diameter or ID honong
  • Shape honing
  • Surface finish for flat honing
  • Positional tolerances of bores

The horizontal and vertical honing process mostly used for finishing was developed to allow for perfection of iner diameter bore, diameter size control, desired surface finish and surface structuring. Precision Surface Peter Wolters can help you develop the horizontal and vertical honing process that can provid size and generate the finish and cosmetic results on the interior of metal shapes or cylindrical interdiameter bores.

Honing is mostly used for finishing. Honing ises an expanding abrasive diamond or slury stone. These honing stones use a suitable grit and grade against the work surface. The stones are rotated with a specific speed and force, reciprocated in the part with hone abrasive under controlled pressure. Peter Wolters has decades of knowlege combining rotation and reciprocation to generate the perfect hatch pattern in the surface of the part being honed.

Why use a PSS, Barnes and Peter Wolters honing machines?

Precision Surface / Peter Wolters can provide and help you:

  • Use honing machines that are capable of removing the stock
  • Generating define exacting specifications
  • Define diamond bore tolerances sizing 
  • Bore and auto polishers 
  • Finishing and buffing bores of almost any material such a: buffing sprayed coatings, CGI, Ceramics, etc.

Define Honing Process in:

The honing process in manufacturing provides the final size and desired pattern on the inner diameter of a metal tube and a metal cylinder bore. Metal and surface finishing is often developed by properly applying pressure on diamond abrasive stones that have the right grit and grade against the work surface. The stones are rotated and reciprocated in the part with hone abrasive under controlled pressure. Combining rotation and reciprocation produces a cross-hatch pattern in the surface of the part being honed.

Precision Surface PSS and Barnes Honing Machines Perform 3 Operations

First, vertical honing is capable of removing the stock up to the ruptured metal and reaches base metal. 

Second, a finish honing pattern is generated to provide the best possible surface for promoting optimum lubricating conditions.

Third, honing stones assures extremely accurate straightness, roundness and size of the cylindrical surface.

What is honing


What is single pass honing machine?

Single pass honing is done with a diamond abrasive products and powders.  Boring bar type honing tool. This type of honing tool generates a round and straight, un-tapered bore in the first pass of the tool through the part. Single pass honing is ideally suited for honing engine crank and cam bores. The shape and size is achieved in one pass, there is no pattern in the finished part. The single pass tool expands the hone stones this adjusts the cone shape similar to standard tooling. Single pass honing stones are not expanded and retracted as with conventional honing. The single pass stones are only expanded to achieve the final size. Please note that single pass hone tool is much longer than standard hone tooling.  Super abrasive coatings across the entire length and the tapered portion about 4.5 inches and has a final size section of 2.5 inches. The single pass tool has no in-process hone expansion, the machine must be stopped to adjust the tool.

When to Choose Precision Surface Single-Pass Bore Honing Tools?

Single-Pass honing machines, also called Bore Finishing, is selected for a variety of applications that have special needs involving honed cavities:

  • Small diameter honing tool machine (normally within 2”)
  • Bore Honing tools for High-production quantities
  • Proper bore honing tools can reduce the cost per part
  • Reduced down-time for CNC honing tool change-over
  • Repeatable accuracy for dimensional tolerances such as bore size, roundness, surface finish
  • Only super-abrasive materials (Diamond and CBN) are used for the Single-Pass processing
  • A high rate/volume of coolant is needed to constantly remove the chips from the honing area
  • Oil or water-base coolants may be used for Single Pass honing, though oil is the most common

Single Pass bore honing process is limited to the types and volumes of material that can be removed. Specifically, the size and volume of chips removed must be no greater than there is clearance between the super-abrasive grits on the tool sleeve. As such, the Single Pass bore honing process is best suited for honing operations that produce a relatively small amount of chips, such as interrupted or short length bores. It is most successful (but not limited to) in honing cast iron and powdered metals.

Applications that feature a long length of material to be honed, small quantities and/or requiring a lot of material to be removed, are not the best suited parts for Single Pass honing. Rather, they may be best served using conventional Stroke Honing. In many cases, conventional Stroke Honing can also provide excellent dimensional geometry for these types of applications.
