Cangzhou De'an manufacturer supplies security brand explosion-proof top

Top, machine tool component in machining. It can support parts with complex end faces and parts that do not allow center holes. The center is mainly composed of the ejector pin clamping device housing, the fixed pin bearing and the mandrel. One end of the ejector pin can push the center hole or the inner hole of the pipe material, and the other end can push the spherical or tapered part. The ejector pin is fixed by a clamping device. When the part does not allow or cannot drill a center hole, the clamping device can be used to directly clamp the turning. The housing and mandrel are drilled with pin holes, and fixed pins are inserted or removed to achieve the dual purpose of the top. The center can also be used for drilling and reaming of workpieces.
A universal machine tool accessory top. It consists of a three-jaw self-centering chuck or a four-jaw chuck connected to the casing through fasteners. There is a bearing between the casing and the mandrel, and a fixed pin. Embedded fit is characterized by a convex pointed cone and oblique spline at one end of the tip, and a concave hemispherical and tapered blind hole at the other end.
