The invention relates to the technical field of manufacturing and processing of marine turbochargers, in particular to a method and a device for processing a ring thrust bearing of a marine supercharger, which are characterized in that after a set of preparation process including rough turning, heat treatment, semi-finish turning and inner hole accurate grinding is adopted, a special taper mandrel for grinding is used for clamping the bearing, and the bearing is clamped by a conical mandrel for grinding; the taper mandrel for grinding has the precise taper of 1: 5000, high surface quality and rigid design matched with the length of a bearing, accurate grinding of all outer circles and end faces is completed through one-time clamping of double tips of a numerical control grinding machine, and online detection is achieved in cooperation with a special auxiliary detection tool. The problem that the form and position precision is difficult to guarantee due to clamping deformation and repeated positioning errors in traditional machining is effectively solved, and therefore high-precision (such as roundness, coaxiality and parallelism are in the micron level), low-deformation, efficient and stable machining is achieved at the same time in the manufacturing process of the large thin-wall annular thrust bearing.

A kind of aluminum double fork arm steering knuckle lower swing arm inverted taper hole processing method and device, adopt drill bit, ball head milling cutter, dovetail milling cutter, single blade reverse scraper, after drilling in closing end, minimum radius allowance is controlled at 0.3mm, ball head milling cutter is according to three-dimensional solid cone spiral side milling wide mouth end, dovetail milling cutter is according to layered way and is carried out semi-finishing and is connected with wide mouth end, after processing, the allowance is controlled as 0.05mm, finally utilize single blade reverse scraper and do finishing, the order is first circle arc feed and retreat tool and do circular interpolation processing, after processing, the allowance is 0.01mm, second circle is also arc feed, after removing the remaining allowance, do third circle arc interpolation finishing tool processing without retreat tool, after processing, arc retreat tool, then tool returns to center position according to the calculation result spindle back direction and is pulled back to finish taper surface, without cutting allowance, simply with finishing tool to finish processing, to reach the purpose of improving surface quality.Thus can replace expensive angle head and realize stable and efficient processing.

This utility model discloses a cutting device for stainless steel coil production, relating to the technical field of cutting devices. The utility model includes a support frame, and further includes: a support part mounted on the support frame for supporting the device on the support frame; a positioning part disposed on the support part for positioning the coil; and a fixing part mounted on the support part for reinforcing the coil. After the coil is placed on the support part, it is centered by the positioning part, preventing deviation during cutting. After being positioned by the positioning part, the coil is further reinforced by the fixing part, further improving the stability during cutting. By setting the positioning part, after the stainless steel coil is in place, a hydraulic push rod is activated, which pushes a corresponding sliding block to move. The sliding block is connected to a transmission mechanism formed by a side connecting rod and a main connecting rod.
