The machine is designed for sharpening various kinds of carbide tipped saw blades from size 80mm to 700mm.It's also suitable to grind other material, such as plastic, wood, aluminum alloy for different purpose like furniture manufacturing, decoration etc. Its fascia can support the teeth of saw blades and other parts in order to prevent jumping and improve grinding quality .This item can shapen all the round saw blade, such as Skil saw. It adopts multi angle of swing, three dimensional slide structures to be in adaptation to the grinding of hard alloy saw blades with many specifications and purposes, which enables the grinding mill to maintain high accuracy and easy operation on any condition. It can work on diameter 3.15"-27.5"(80mm-700 mm)The fuselage is made of aluminum, which is long-lived and not easy to be corroded. Pure copper motor, stronger stability and higher efficiency, can work continuously for 20 hours a day With a precise scale, it is easy to adjust the feed angle and reduce the accuracy error.Worktable with a rotary table, easy to adjust sharpening feed angle. Grinding head has positive and negative 20 rotation mechanism,it meet the request of oblique edge blade sharpening.
