To choose a suitable elastic rotary ejector pin, look for a manufacturer with guaranteed quality. The elastic rotary ejector pin is mainly used for processing shaft sleeve parts on larger lathes. Due to its large load-bearing capacity, it can absorb the thermal deformation of the workpiece through automatic adjustment and control thermal stress. Therefore, it is most suitable for high-speed and powerful cutting.
The working principle of the driving ejector pin: The driving ejector pin is a new type of machine tool accessory. It relies on the driving claw to embed the end face of the workpiece so that it can rotate with the machine spindle, thus completely replacing the chicken core chuck and chuck. Connection between the driving ejector pin and the machine tool: There are three types of connection methods for the machine tool: Morse taper shank, flange connection and soft claw clamping, which are easy and reliable to install and use;
The driving ejector pin has a special tip for various types of machine tools Uniquely designed, the three categories of driving ejector pins for turning, grinding and gear processing meet the needs of various occasions. The ejector pins adopt patented dynamic balancing and automatic compensation systems inside, so even if the tip is against a blank part or a bevel, it can still be processed. There are three connection methods with the machine tool: Morse taper shank, flange connection and soft claw clamping. It is easy and reliable to install and use. In the finishing turning and grinding series, the fixed connection of the central ejector pin enables accurate positioning of the axial dimensions. The ejector body can be used with drive paddles of different specifications to process bushing parts with an outer diameter of 5 to 400mm or even larger.
There are many types of rotary ejector pins. When we use them, we choose different rotary ejector pins according to the specific conditions of use. Heavy-duty elastic rotary ejector pins are mainly used for processing shaft sleeve parts on larger lathes. Due to its large load capacity, it can absorb the thermal deformation of the workpiece through automatic adjustment and control thermal stress. Therefore, it is most suitable for high-speed and powerful cutting. Ejectors can also be used for drilling, threading and reaming workpieces. A universal machine accessory thimble for machine tools. 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, which is embedded and matched with a fixed pin. The characteristic is that one end of the ejector pin has a convex pointed cone and oblique spline, and the other end has a concave hemispherical and tapered blind hole.
