Single Pass Honing Machine

Khushbu Engineers offers Single Pass Honing Machine, Model SP 650. This is designed for higher productivity and accuracy of bore geometry. Very close tolerances can be achieved consistently with required surface finish through single pass honing process. In single pass honing, a rotating diamond impregnated tool is passed once through the bore. Either the tool or the job is floating. The removal of material is done by diamond cutting points. High wear resistance of diamond-impregnated tool ensures the repeatability of the bore size within 0.001-0.003 mm. While, bore roundness, straightness and surface finish can be achieved within desired tolerance. Life of the diamond-plated tool is extensively high, resulting in low cost operation. It is applicable for any types of bores, like through stepped or blind and almost all type of material combinations. The operation of this machine reduces the cycle time resulting in higher productivity. With automation, production rate of 400 nos./h can be achieved. It is very simple operation as compared to conventional honing. Features of the single pass honing machine are servo controlled vertical motion and indexing, Siemens/Mitsubishi controller, CNC index table, ball screw and LM guide, automatic lubrication system, overload sensors, precision class spindle bearing, stroke length 450 mm, variable spindle speed, compact machine base, interlocks 8 hp power consumption, etc. Benefits: higher production rate, low operation cost, low labour cost, quality consistency, bore geometry improvement, frequent inspection not required, etc.
