WHAT IS HONING?

High precision honing is a super-finishing process performed removing a small amount of stock from cilindrical-shaped bores of components belonging to various industrial applications. The process is established to improve the bore’s geometric accuracy, up to sub-micron tolerances.
Stock removal is achieved through special abrasive spindles, single or multi-stroke. Upon the customer’s priority, the machine can be built with single or multi-stroke spindles: Melchiorre supplies both solutions.

MELCHIORRE MACHINES

Melchiorre machines, series “ELV”, are equipped with electro-mechanical movements controlled by PLC. This system, patented, allows to achieve the strictest accuracies and the highest stock removal rates. The monolithic structure guarantees extreme stiffness, avoiding every vibratory phenomenon.
Working parameters are set through a touch screen operator panel: different programs can be stored following each component in process.
To achieve the best quality, in-process and post-process measurement systems are avaibable, for a direct control during the process operations.
Very precise spindles, single or multi-stroke, are installed for a perfect quality repeatability. The tables, as well, are designed upon the specific application: rotating, cross, transfer, etc. Thanks to the flexible manufacturing, some characteristics of the machine can be changed without any deep modification to the existing structure (i.e. number of rotating tables forn the single stroke machines).
Spindle strokes are available upon request, up to 1000 and more mm. Bore diameters up to 250 mm. Whenever needed, to increase farther the production, Melchiorre supplies also the automation to load-unload the parts.
