FIELD: machine engineering, possibly finish abrasive working of helical surfaces of precise screws such screws of screw pumps of hard-to-grind materials by embracing grinding process.
SUBSTANCE: method comprises steps of imparting rotation to part with revolution number depending upon cutting properties of abrasive material; imparting to tool crosswise in-feed motion and reciprocation lengthwise feed motion; using as tool flexible wire roller to which abrasive layer is secured.
EFFECT: enhanced quality, efficiency of working due to using embracing grinding process and due to rotation of tool itself for providing increased surface area of tool and blank contact, and high cutting rate.
