The technical solution of the utility model is:
A kind of aspheric surface numerically controlled lathe that utilizes the turning of diamond bit single-point, comprise computer control system 1, lathe bed 2, X to slide unit 16, Z to slide unit 3, main tapping 8, synchronous belt transmission device 7, diamond bit 11, knife rest 12, workbench 13, anchor clamps 9, it is characterized in that Z is installed on the lathe bed 2 to slide unit 3, X is installed in Z on slide unit 3 to slide unit 16; Workbench 13 is installed in X on slide unit 16, and diamond bit 11 is installed on the workbench 13 by knife rest 12; Main tapping 8 is installed on the boss 6, and boss 6 is installed on the lathe bed 2, and anchor clamps 9 are installed in main tapping 8 front ends; Workpiece 10 is installed on the anchor clamps 9, drives it by main tapping 8 by anchor clamps 9 and realizes that C is to gyration; The motion of the relative workpiece of computer control system 1 control cutter realizes the processing to the aspherical eyeglass lens profile.
Described anchor clamps 9 are aspherical eyeglass lens turning special fixture, realize the quick-clamping of workpiece 10.
The utlity model has following advantage:
1) handle the aspheric surface model data by computer control system, space motion between control diamond bit and the workpiece has solved the difficult problem of aspherical eyeglass lens processing.
2) surface quality is good.Have advantages such as low-friction coefficient, high thermal conductivity, high rigidity as cutter material with diamond, reach and sharp cutting edge by sharpening, cutting force is less in the process, thereby the surface quality that can obtain.
3) machining accuracy height.Adopt the turning of diamond bit single-point, can process high-precision aspherical eyeglass lens.
4) working (machining) efficiency height.The automaticity height of numerically controlled lathe can once obtain size, form accuracy, the surface roughness of aspherical eyeglass lens, thereby improves working (machining) efficiency.
