TL;DR: In this article, a servo-hydraulic double-feeding mechanism for a numerical control vertical cylinder sleeve honing machine is presented, which includes an inner push rod and an outer push rod positioned at the middle part of a hollow stroke main shaft.
Abstract: The present invention discloses a servo-hydraulic double-feeding mechanism for a numerical control vertical cylinder sleeve honing machine, which comprises an inner push rod and an outer push rod positioned at the middle part of a hollow stroke main shaft, wherein the inner push rod is positioned in the outer push rod; the outer push rod is driven by a servo feeding closed-loop control mechanism to move up and down; the inner push rod is driven by a hydraulic feeding closed-loop control mechanism to move up and down; and a programmable digital control system is connected with sensors in the a servo feeding closed-loop control mechanism and the hydraulic feeding closed-loop control mechanism to realize straight line-driven closed-loop feedback and hydraulically-driven closed-loop feedback, and is arranged outside an integrated safety protector of a machine tool. The servo-hydraulic double-feeding mechanism has the advantages of simple structure, rational layout, excellent working stability and reliability, high machining precision, a visual operating interface and the capacity of realizing the high-quality machining of a flat reticulate pattern for a cylinder (sleeve) internal hole of an internal combustion engine.

TL;DR: In this article, the mixing process of different components of abrasive stones of cubic boron nitride used for rough honing was studied and the homogeneity degree of the abrasive content of different samples in a mix was determined through two new parameters introduced in the present study.
Abstract: In the present work, the mixing process of different components of abrasive stones of cubic boron nitride used for rough honing was studied. Stones are made by the sintering process of abrasive grains, a metallic bond, and a humectant that favors covering of each abrasive grain by the bond. Incorrect mixing of abrasive grains with the bond and humectant can result in stones with nonuniform abrasive grain distribution. As the abrasive stone wears out, grain distribution will vary and modify efficiency of the honing operation. Tin is the metal having the lowest melting point among metals in the bond. By means of a scanning electron microscope and energy-dispersive X-ray microanalysis, tin segregation was discarded, which could have led to abrasive grain segregation. Later, mixing tests of the different components of the stones were performed at different mixing times. Both homogeneity degree of the abrasive content of different samples in a mix and covering degree of abrasive grains by bond were determined through two new parameters introduced in the present study. It was noted that use of a chain to accelerate the mixing process excessively reduces covering degree of abrasive grains even at initial mixing times. The highest quantity of humectant is recommended in order to get better covering degree. Mixing time should be high enough to assure homogeneity degree of the mix but low enough to avoid excessive reduction of covering degree.

TL;DR: In this article, a valve housing of an automobile steering valve assembly is processed by rough slotting-precision boring of an inner bore-finish slotting and fine-tuning the inner bore.
Abstract: The invention relates to a processing method of a valve housing of an automobile steering valve, including the following steps: lathe machining, drilling, rough slotting-precision boring of an inner bore-finish slotting and honing the inner bore; wherein, in the step of rough slotting-precision boring of an inner bore-finish slotting, rough slotting of six slots is firstly carried out, a margin of 0.1mm is kept, then precision boring of the inner bore is carried out, a honing margin of 0.05mm is remained, the burrs after rough slotting are removed and then finish slotting of six slots is carried out. Compared with the prior art, the valve housing of the steering valve produced by the method can greatly raise the first-time qualification rate of the assembly of the steering valve, the performance curve of the steering valve is stable and has small fluctuation, and the noise of a steering engine can be significantly lowered.
