The WVN-300 hone is constructed in two pieces. For instance, it consists of the honing section and the work-holding section. The hone section is made from welded structural tubing with excellent rigidity. On the top of this section there is a base that supports the honing head, and displacement guides that move the hone head back and forth.

Product Info


The hone head inline movement is driven electronically. For example, the hone head rotation turns through a variable reducing motor that allows the hone head to cover the 1.58” – 32” honing range. The R.P.M change is performed manually. Additionally, the hone head expansion is performed electronically by a motor and reducer directly from the control panel. There are two steady-rests, one of which is fixed one at the end of the table, and another that is adjustable to help support the work piece.
