The system is especially suited to the Delapena range of honing machines which possess the power and performance to accurately hone bore diameters up to 762mm. The simple interchange of honing heads ensures application versatility and production efficiency. The vertical honing system can also be used with a variety of equipment, including tube hones, borers, radial or pillar drills and portable power tools.
The Friction Feed Unit
The friction feed unit facilitates honing stone contraction and expansion whilst the stones are rotating in the bore, eliminating the need to halt the process to adjust honing pressure. Control of stone pressure provides improved accuracy and consistency of the honing process.
The Honing Heads
The three smaller honing heads use a twin cone expansion mechanism. These heads accommodate stone sets mounted directly to the head and are suitable for bore diameters of up to 68.3mm. The three larger hone heads use a rack and pinion expansion mechanism.
Driveshafts are available in a wide range of lengths for both friction feed and manually adjusted operation. Standard manual driveshafts have a hexdrive.
The Stone Sets
Unless otherwise ordered, standard stone sets will be supplied as follows :
Where bore irregularities, such as ovality need to be corrected, two stones and two guides should always be specified.
The Stone Carriers
For smaller diameters, within the standard head range, stone sets are mounted directly onto the hone head. For standard head applications of greater than 92.25mm diameter and all major and giant head applications stone carriers are required. These reusable units take replaceable, plug-in stone sets, which are interchangeable to ensure that a small range of stones cover a wide variety of applications.
The Stone Supports
For bore diameters greater than 158.75mm, additional rigidity is provided to the honing head assembly by incorporating a stone support. The stone support steadies the stone carriers and stones to ensure consistent honing performance.
The CG100 Adaptor
Where it is required to hone smaller diameters than 25.4mm and it is not possible to use a hand operated horizontal honing machine, e.g. where the component is too heavy or bulky to be held by hand or for honing bores in situ, the Delapena CG100 adaptor may be used.
