Description
Technical Field
The invention relates to the technical field of dry grinding processing, in particular to a nano-fluid continuous controllable internal spraying low-temperature sintering grinding wheel grinding system.
Background
In machining, grinding remains one of the most important machining processes. Most of energy consumed in the grinding process is accumulated in a grinding arc area in the form of heat energy, and a large amount of heat is easily accumulated on the surface of a workpiece in the grinding process, so that a grinding wheel and the workpiece are burnt and scrapped. Therefore, the grinding arc area is mostly cast by cutting fluid during grinding, and in order to improve the lubricating property of the cutting fluid, additives are often added, and most of the additives in the cutting fluid are toxic and harmful substances. The common cooling methods in grinding processing include external cooling and internal cooling. The external cooling is a common cooling mode, the external cooling cools the contact surface between the cutter and the workpiece through an external cooling pipeline or externally sprayed cooling liquid, a large amount of cooling liquid is needed in the cooling process, the environment is greatly influenced, and meanwhile, due to the air flow barrier blocking effect of the high-speed rotating grinding wheel, the cooling efficiency is not high. The internal circulation cooling mode is used for forcibly cooling a machined workpiece or a grinding wheel in the grinding process, and the internal cooling mode is used for designing the internal structure of the cutter. However, due to the reasons of low thermal resistance of the wall thickness of the cutter, low heat exchange efficiency of thermal circulation and the like, the cooling efficiency of the cooling mode is not high generally.
It is therefore important how the grinding temperature can be reduced. The existing cooling mode is mainly that cooling liquid is added externally, so that the production cost is increased, and the environmental pollution is caused, so that the design of the low-temperature sintering inner-cooling CBN grinding wheel with controllable inner-spraying nano fluid has important significance.
Dry grinding has little environmental pollution and simple process, but has insufficient cooling performance and high requirements on equipment such as machine tools and the like.

The solid coating grinding wheel lubrication technology can cross a grinding wheel air flow barrier and has antifriction performance, but the cooling performance is not high, and a lubricant cannot be continuously separated out. The air current barrier can be crossed in interior cold emery wheel abrasive machining, has the rotation unbalance, the extravagant problem of coolant liquid.
The cooling mode at present among the correlation technique is mainly that the outside adds annotates the coolant liquid, and the contact surface between external cooling passes through external cooling pipeline or spouts the coolant liquid outward to cutter and work piece cools off, needs a large amount of coolant liquids in the cooling process, and is very big to the environmental impact, simultaneously because the air current barrier of high-speed rotatory emery wheel hinders the effect, and cooling efficiency is not high, has not only increased manufacturing cost, has caused environmental pollution's problem moreover, has not proposed effectual solution at present.
