● Thread turning device Thread turning device is a sort of slicing device, that's a sort of device used for thread slicing on a turning gadget.

● Thread turning equipment are divided into  categories: inner thread turning equipment and outside thread turning equipment. From the preliminary degree of mechanical manufacturing, thread turning equipment that require hand-grinding welding heads, thread turning equipment floor from high-velocity metallic materials, and high-velocity metallic comb blades Type thread turning equipment and gadget clamp thread turning equipment, etc. The gadget clamp thread turning equipment are presently broadly used gadget clamp thread turning equipment. The gadget clamp thread turning equipment are divided into  parts: a shank and a blade. It is geared up with a shim, that's pressed with screws, and the blade is hooked up at the shim. The blades are divided into tough alloy uncoated blades (blade used to technique non-ferrous metals, including aluminum, aluminum alloy, copper, copper alloy and different materials) , Carbide lined blades (used to technique metallic, solid iron, stainless metallic, alloy materials, etc.).
