16*200--30*500（mm）

Top, machine tool components in machining. It can support parts with complex end faces and parts that do not allow center holes. The center is mainly composed of an ejector pin, a clamping device, a housing, a fixed pin, a bearing and a mandrel. One end of the ejector pin can push against the center hole or the inner hole of the pipe material, and the other end can push against a 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, threading and reaming of workpieces. A universal machine tool accessory tip, which 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, which is embedded and matched with a fixed pin. The characteristic is that one end of the tip is a convex pointed cone and oblique spline, and the other end is a concave hemispherical and tapered blind hole.
