Vikrant Special Machines Pvt Ltd offers an Edge Rounding Machine. With an edge-rounding machine, in one pass it is possible to process both sides of the parts. With typical belt machines the parts need to pass through twice to do the same work. A strip is fed continuously through adjustable guides into the 2 machining stations, viz., a. Gang milling for 'T' section, and b. Rounding/taper machining. At each machining station spring loaded pressing rollers hold the strip during the machining operation. The number of adjustable guide rollers is provided at entry and exit ends to guide the strips through machining. A centralised powerful vacuum dust extraction is provided at two points. For accommodating various widths of strips one of the rounding cutter heads will be adjustable in the horizontal plane. To accommodate various thicknesses of strips, the machining heads will have vertical adjustment also. The gang milling cutter set consists of 3 side and face cutters, 2 units of dia 100 mm, and the sandwiched cutter of dia 90 mm x 11 mm wide. For rounding operation, two concave cutters of dia 63 mm with r = 2. For taper milling one of the above stations will be provided with suitable cutters to suit job profile. For strip feeding, two AC motors with synchronized speed will be provided at entry and exit points of the strip.
