Drill Chuck is one of the main parts of the power tool industry and machine tool industry, widely used in hand drill and a drill press. Connected to the drill chuck, for holding the attachment shank type tools. Its threaded connections and connection cone drill two way connection. Threaded connection is mainly used for the Dongying hand drill machine tool accessories, cone connection is mainly used for drilling. Drill chuck from the structure and manpower mainly wrench type two categories. CHUCK wrench to tighten wheel wrench required, mainly for the machine tool industry, such as on a bench and hand drill. Because it is by drill chuck wrench wrench to tighten the clamps round of Linyi machine tool accessories, and pull the wheel is an extended arm of the bevel gear Zaozhuang tool accessories tool belt, so the tightening process, may serve to increase the torque input effect, so the chuck clamping force. Because wrench chuck simple structure, easy processing components, cheap, reliable performance, so its wider use. Three main parameters are precision drill chuck clamping force and clamping range. Runout accuracy is used to control the clamp handle class tools to ensure the accuracy of machining hole. Clamping force is to ensure the holding of the handle class tool does not slip, prevent slipping handle class tools and unable to work. Under normal circumstances the accuracy requirements for the chuck on the high bench for some, but for precision hand drill chuck on relatively low. Clamping range is used to control the chuck gripping means minimum and maximum diameter, in order to meet operational needs. Specification refers to the maximum diameter of the chuck clamped. Cone drill chuck features: a high-precision tapered bore 2 shell in the harsh environment can effectively prevent rust 3 jaws special treatment, with good abrasion resistance four precision accurate and reliable, durable Linyi machine tool accessories, machine tool accessories tools, provided by the Shandong Shandong Bot Bot Seiko Seiko Corporation.
