Honing

DIAMOND TOOLS FOR HONING

 

„Honing“ is a process of precision surface on a workpiece, i.e on various materials, such as hardened iron, steel, bronze, ceramics, glass, graphite etc.

Honing tools (abrasives) are fixed onto specific hone heads (mandrels) by brazing or sticking, or they are set into the spindle lathe carrier. The head with the abrasive perform three motions:

- rotary motion
- axial motion, and
- radial motion for approaching the abrasive to the workpiece

Honing is mostly used on inner cylindrical surfaces of various radius, rarely on outer surfaces, because the outer surface finishing can be easily done by superfinishing. The type of the head carrier and the honing tool (abrasive) should be conformed to the size of the workpiece opening.

Proportion between the workpiece opening length (L) and the radius (d) should be L/d ≥ 2.

Tool cross-trace angle (α) depends on the perimeter and axial speed, but it mostly makes 45°, depending on the type of material.

The honing pine should not be pulled out over 1/3 of its length.
Possible after-honing surface finishing depends on the honed surface radius, material type, and honing precision (rough or finishing).

Besides appropriate selection of perimeter and axial sped, as well as diamond type and granulation (diamond or boron), it is also important to exert appropriate pressure onto the abrasive stone, to select appropriate temperature, and to provide lubrication and cooling during honing.

By diamond tool honing you will:

- improve geometric form of the workpiece
- get a functional surface texture
- avoid uneven spots

Honing is mostly applied in:

- auto and motor industry
- hydraulics and pneumatics field
- compressors
- precise mechanics

After twenty years of work practice, “DIJAMANT” craft workshop can offer a wide range of honing tools, size and quality of which depends on customer requirements.
