DEVICE FOR TURNING OF FLEXIBLE PARTS Russian patent published in 2014 - IPC B32B1/00 

FIELD: process engineering.

SUBSTANCE: this device consists of basic case secured in lengthwise groove of standard tool holder of universal lathe with tool holder fitted in rolling guides and provided with cutter rigidly secured thereto. Power drive is arranged between tool holder and basic case. The latter comprises resilient element composed of outer and inner coaxial flexible rings connected by lengthwise and crosswise links provided with left and right lengthwise levers and top and bottom levers, respectively. Electromagnet with moving element composed by permanent magnet with conical working end its maximum stroke being limited by screw. Strain gages connected in Winston electrical bridge are wound on extending ends of inner flexible rings, nearby the ends of on inner and outer flexible rings. Outputs of said strain gage are connected to ACS composed of strain gage amplifier, comparator equipped with memory unit, signal amplifier with outputs connected to electromagnet output terminals, all being connected in series.

EFFECT: higher precision and quality of turning.
