High-speed dry type roll-cutting process

Abstract

The invention discloses a high-speed dry type roll-cutting process. The high-speed dry type roll-cutting process comprises the following steps: step S1, selecting a proper high-speed numerical-controlgear hobbing machine, selecting a proper cutting tool, checking various working data of the high-speed numerical-control gear hobbing machine in detail before roll-cutting and processing, ensuring ajoint connecting position of a power supply circuit to be free of a loosening condition, and enabling the high-speed numerical-control gear hobbing machine to normally work; and step S2, clamping andfixing a workpiece to be subjected to roll-cutting processing onto a claw disc of the high-speed numerical-control gear hobbing machine through an automatic clamp, determining selected cutting conditions during roll-cutting before dry type cutting, and inputting parameters of high-speed dry type roll-cutting into the high-speed numerical-control gear hobbing machine, wherein a roll-cutting schemeis a high-speed dry-cutting rolling gear, and the gear is a dry-cutting inclined gear. The high-speed dry type roll-cutting process reduces environmental pollution, avoids a condition that cuttings are adhered on a knife, facilitates reducing roughness of a workpiece processing surface, shortens cutting and processing work-hour, improves production efficiency, and reduces processing cost.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a high-speed dry rolling cutting process. Background technique [0002] Traditional gear manufacturing mostly adopts wet hobbing process. In the process of wet hobbing, cutting fluid is usually one of the indispensable production factors in most machining, which plays an important role in ensuring machining accuracy, improving surface quality and production efficiency; With the enhancement of global environmental awareness and the stricter requirements of environmental protection regulations, the negative effects of cutting fluids on the environment are becoming more and more obvious.

[0002] Traditional gear manufacturing mostly adopts wet hobbing process. In the process of wet hobbing, cutting fluid is usually one of the indispensable production factors in most machining, which plays an important role in ensuring machining accuracy, improving surface quality and production efficiency; With the enhancement of global environmental awareness and the stricter requirements of environmental protection regulations, the negative effects of cutting fluids on the environment are becoming more and more obvious. Extensive use of cutting fluids can easily lead to problems such as ecological environmental pollution and occupational health hazards for workers; while dry type Cutting is a cutting process that consciously does not use cutting fluid and performs cutting without cooling fluid in order to protect the environment and reduce costs; the high-speed dry hobbing process in the prior art, in the hobbing process, Due to the lack of lubricating effect of cutting fluid, the chips produced by hobbing cutting are not easy to separate from the workpiece, which leads to the tendency of chips to stick to the knife under high temperature conditions, which affects the quality of hobbing cutting. Therefore, it is very important to design a high-speed dry hobbing cutting process. Necessary
