The invention provides an inner-cooling type hobbing cutter which comprises a cutter rod and a hobbing cutter body. An oil hole channel is arranged in a chip containing groove, corresponding to front cutter faces of cutter teeth, of the hobbing cutter body. A hole plug is correspondingly arranged on the upper portion of the oil hole channel, and the lower portion of the oil hole channel is communicated with a cutter retreating groove of the hobbing cutter body. The whole plug with an jet hole in the head portion is connected with the oil hole channel through threads. A cutter rod axial oil hole and cutter rod radial oil holes communicated with the cutter rod axial oil hole are formed in the cutter rod. The cutter rod axial oil hole is communicated with a center hole of a connector stator through a center hole of a connector rotor. The oil hole channel in the hobbing cutter body and the hole plug for opening and closing the hole channel are adopted, cutting oil / liquid and compressed air are directly jetted on the front cutter faces of the cutter teeth of the hobbing cutter body through the oil hole channel, the cooling and lubricating function is fully achieved, the temperature of the hobbing cutter is reduced, the service life of the hobbing cutter is prolonged, the hobbing cutter can direct jet cooling media nearby a cutting area, cutting heat is taken away to the greatest extent, and the influence of the cutting heat on hobbing machining is reduced.

A demetallating process for the hydrocarbon oil includes such steps as mixing the acetylacetone as demetalating agent with raw hydrocarbon oil, water and demulsifier, and oil-water separation. Its advantage is high effect to remove Ca, Mg, Fe, etc.

The invention provides a method for machining a narrow groove system impeller, a grinding head and a preparation method of the grinding head. The grinding head is a cylinder. The top end of the grinding head is in the shape of a spherical surface, and a spiral groove is formed in the side wall of the grinding head. The preparation method includes the steps that materials for use are calculated; ingredients are weighed; wetting and material mixing are performed; pressing of grinding head sand blocks is performed; drying is performed; the firing link is performed; and the grinding head sand blocks which are qualified through checking are selected and enter an adhesion processing procedure of a cutter handle, the cutter handle is bonded, after adhesives are cured and stabilized, laser dressing is performed, grooving is performed, and acceptance check of the grinding head is performed, and therefore preparation of the grinding head is completed. The method for machining the narrow groove system impeller through the grinding head includes the steps that fluttering stability analysis is performed, and a stable lobe graph of a grinding system is established; the technological parameter selecting range of stable grinding is determined; and technological parameters of stable grinding are selected, and the grinding head is installed for grinding machining. By means of the grinding head, the grinding temperature is effectively lowered, the adhesion and abrasion effects of cuttings on the grinding head are reduced, the machining surface burning problem is reduced, and better machining surface quality is acquired.

The invention belongs to the technical field of metal cutting tools, and relates to a self-cooling hob that prevents chips from remaining. It is characterized in that it includes a hob body and a rotating installation head; At the installation end, a central hole is opened in the hob body, and a spiral blade is fixedly arranged in the center hole; a channel is opened inside the first installation end, and the channel communicates with the center hole; through holes are evenly opened on the circumferential side of the first installation end, and the through hole It communicates with the channel; the rotating connector is rotatably installed on the first installation end, and the rotating connector covers the through hole; the connecting port is provided on the rotating connecting head, and the connecting port communicates with the channel through the through hole; the rotating connecting head is also provided with a leak A pressure port and a pressure relief port are provided with a convex ring and a pressure relief valve, and the pressure relief port communicates with the channel through a through hole. The invention can not only flush away chips at the bottom of the cutting edge, but also reduce the influence of cutting heat on gear hobbing, reduce the temperature of the hob, and prolong the life of the hob.
