Honing is the cutting technique of choice when you want to achieve precise accuracy, roundness and roughness. We are happy to tell you more about what honing is and why it is used. Also discover the power of honing and learn how we can use honing technology for you.

What is honing?  
Internal diameters ranging from ø 1.55 mm to ø 1,880 mm and lengths of up to 27,000 mm.
When honing internal bores, the honing tool rotates in the longitudinal direction of the workpiece under permanent surface contact in the bore along the longitudinal axis of the workpiece.
The simultaneous stroke and rotating movement ensures the cross-grinding characteristics of honing.

Internal honing 
Internal diameters ranging from ø 1.55 mm to ø 1,880 mm and lengths of up to 27,000 mm.
When honing internal bores, the honing tool rotates in the longitudinal direction of the workpiece under permanent surface contact in the bore along the longitudinal axis of the workpiece.
The simultaneous stroke and rotating movement ensures the cross-grinding characteristics of honing. 

External honing 
This also applies to external honing of shafts. However, in this case, it is the workpiece that rotates instead of the tool. The external dimensions of the shafts vary from ø 50 mm to ø 400 mm, with lengths of up to 6,500 mm.

Honing bends 
For a business relation in the process industry, we have developed a honing device to hone bends with a radius of 180 degrees, depending on the internal diameter.  

How is honing performed?
Honing is carried out using machines specially designed and developed for this operation. The machines are available in both horizontal and vertical versions.

A wide variety of honing tools are used. These include honing heads and honing mandrels. We  also use different types of honing stones for final processing of:

• Diameter
• Form
• Surface roughness
• Position tolerances of bores (squareness)

The honing process is designed to allow perfection of bore geometry, size control, final surface finish and surface roughness. The honing process provides the final dimensions and creates the desired finishing pattern on the inside of tube or cylinder bores. The finish is achieved by selecting the right honing stone of suitable grain and quality for the work surface. The stones are rotated and moved back and forth along the surface to be honed under controlled pressure. By combining rotation and reciprocating motion, a honing angle is created on the surface of the product to be honed.

The advantages of honing
Honing is a cost-effective processing method for:

• Machining: today's techniques allow for larger material removal;
• Generation of accurate tolerances;
• Generation of accurate surface roughnesses;
• Machining bores in almost any material, such as: steel, stainless steel, cast iron, aluminium, brass, cutting metal, but also sprayed coatings, hard chrome, ceramics etc.
