Gusev V.G., Andrianov S.B. The flow cooling lubricant through the mechanical seals concentric grinding tool

The flow cooling lubricant through the mechanical seals concentric grinding tool

Gusev V.G., Andrianov S.B.

Paper deals with the flow of coolant through the concentric gap between the end plate and non-contact surface of the workpiece machined with internal teams of coaxial grinding tool. Installing the tool of special mechanical seal guarantees the high-pressure coolant in the treatment area, and the clearance significantly increases the basic cutting parameters. The geometrical parameters of concentric gap, as well as geometric shape and size of the external (working) the seal had a significant influence on the coolant pressure in the treatment area. Modeling and calculation of hydrodynamic flow coolant through the gap to determine the optimal value of leakage, which guarantees removal of sludge from the treatment area, reducing the thermal stress of the grinding process, as well as to control the pressure in the cutting zone.

Keywords: wear rings, coaxial grinding, coolant pressure, cutting zone.

Nikitina L.G. Methods of measurement of parts on CNC machine tools

Methods of measurement of parts on CNC machine tools

Nikitina L.G.

We consider the ways and methods of measurement of parts on machine tools. Depending on the type of production is following methods of measurement on machine tools: measurement during processing and measurement under interrupted processing. When using the “measurement in processing” automatically measured geometrical and technological parameters of the cutting process in the case of deviations from the nominal values produced is automatic adjustment of the cutting process. Way to measure “in the interrupted processing” is used in cases where the parts have complex geometry and the machine handles a wide range of parts in small batches, which fully complies with the conditions of processing on CNC lathes. The choice of method depends on the measurement method of processing, measurement conditions, the required accuracy of measurement, the size of the party details and their nomenclature, the type of machine and the degree of automation.

Keywords: measurement methods, techniques, cutting machine, adjusting the quality of the product.

Kokoreva O.G. Increase of durability of heavy-duty machine parts of surfaces static-pulse treatment

Increase of durability of heavy-duty machine parts of surfaces static-pulse treatment

Kokoreva O.G.

Offered for practical use in production the new method of statiс-pulse hardening of hard loaded surfaces has a number of essential advantages in comparison with applied now. Distinctive feature of a method is the combination of static and dynamic processes of processing as a result of which necessary qualities of a blanket of a processed detail, and as necessary hardness and residual tension of compression are provided. This way of hardening is one of more effective, energy saving and easily realized in production. Static-pulsed hardening increases the number of controlled design, tuning, and technological factors that affect the result of hardening. As a result, the static-pulse processing provides reduced surface roughness, increased wear resistance and hardness of the surface layer by increasing the depth of hardening and changes in the microstructure of the metal. For the static-pulsed hardening is characterized by high performance and low cost compared with heat treatment and explosion.

Keywords: static-pulse treatment, hardening the surface, quality characteristics of the surface layer, reliability, durability.
