No clutch and brake on the machine design and application of impact

No clutch and brake tools,such as desktop milling machine Z7030,in emergency braking or the use of disk-shaped milling cutter parts,linkage spindle speed movement of the belt pulley wheel groove,easy to rupture,resulting in the machine can not run.Spindle speed of the belt movement with DaLun wheel design of the structure of the sleeve type structure with combination,can improve no clutch brake equipment and DaLun hub of machine tool impact strength,avoid the emergency brake or processing components with wheels are caused by a ruptured the keyway machine downtime.
