To solve turning the treatment of organic glass spherule, author trial-produce a kind of brief form is spherical lathe tool, improved manufacturing efficiency and spherical treatment quality greatly, and cutting tool is made very handy also. Form of attached drawing canister is spherical lathe tool turning organic glass, can encounter turning ball diameter sometimes very small spherical, and precision asks again very tall, if use example knife treatment, it is very difficult that cutting tool blade is ground. To solve the treatment of spherule, trial-produce a kind of brief form is spherical lathe tool, if attached drawing place is shown. What it can machine ball diameter to be less than 10 Mm is spherical, improved manufacturing efficiency and spherical treatment quality greatly, and cutting tool is made very handy also. The material of cutting tool is 45 steel, quench hardness is controlled for 45HRC, each are ground to Ra0.
8 the following. Be like cutting other material, cutting tool material should choose high-speed steel or tool steel, quench. The cutting speed of rough machining is 30m/min left and right sides, the cutting speed of finish machining is 2mm/min left and right sides, lubricate with kerosene. Blade diameter D must be less than the spherical diameter of a treatment, general small 0.
5mm left and right sides. When holding a knife, the center of blade diameter D must agree with work center photograph. CNC Milling
