The present invention relates to a hydraulic chuck having a grinding wheel Vigan feeding head structure and the back-operated flow path structure.
Thus in the oil pressure chuck is a technical base is composed of a head and body of the present invention, the inclined plane having a slope at an angle set, loading the front end rim of the head is formed in the end mill (tools: Tool) polished during polishing in the mounted state prevent the wheels from getting (polished is conveyed in the axial direction from the grinding table, the wheel is prevented touching phenomenon at the front end border edge side of the head that bite the end mill) bar, which rupture of the polishing head, to prevent damage and breakage and it is characterized in that by grinding so that the fluid contained within the head such that no leakage safety and workability is significantly improved.
Thus, the present invention is the slope of the head (polishing interference-proof structure of the wheel) due to the formation from the high to the rear of the injection hole mounting part according to the narrowed mounting the front end side border exterior diameter governments promote a fluid-filled safety On the other hand, the fluid receiving Section width portion bar, which of Ø3 ~ 5 small diameter to allow miniaturization of the end mill is attached (previously, also fitted to the collet in the middle) is formed to be clamped on a small-diameter tool (end mill) smoothly without collet using to allow to be characterized.
In addition, the present invention provides an alternative embodiment, the head and the body are integrally formed (the axis a machining center new equipment yeoseo the axial center of the spindle to the correct state, that is, applied to do not need to precisely align the concentric structure), or the head and the main body is removable to enable any of the forms that are assembled (machining center is used equipment applies in the case of form due to the axial center deformation of the spindle must be updated to adjust the axial center of the head relative to the body assembly to the spindle) It is formed.
Thus, the invention is an additional embodiment example, the head and the body relative to the main body when the separating structure to the head can easily and quickly set up the concentric (axial center) leveling adjustment settings groove (and the adjustment screw) and the vertical axis which is characterized in that the processing quality because of the superior end mill secured precision jangchakseong bar, to adjust the groove is easy to work precisely and concentrically sophisticated (axial center) set against formation to occur.
