New Wire EDM Capability: <\/strong>Here is a good example of what the rotary axis can do.This nitinol pin is used to hold a dental implant onto a special wrench during implant surgery. The material is very hard and also super elastic making it very difficult to machine conventionally. This tiny part was burned in one setup on the wire EDM to tolerances of +\/- 0.0002\u201d using the rotary axis in indexing mode.<\/p>\n<\/div>\n<\/div>\n

Another tiny part cut with the rotary axis.\u00a0\u00a0 Parts like these are still expensive to cut using such a slow machining process but there is really no other way to make something like this.\u00a0 By the way, the little vanes are 0.015″ thick and 0.020″ wide.\u00a0 They will be laser welded onto a 1\/16″ diameter tube, then cut free from the stub at the bottom of the picture.\u00a0 If you look closely, you can see a tiny notch cut into each vane…that’s where I’ll make my cut under the microscope with a diamond disc.<\/p>\n<\/div>\n<\/div>\n

Shown is an experimental surgical bur used by a scientist for bone surgeries on rodents.\u00a0 It was\u00a0one of several attempts\u00a0to find the best geometry for the cutting tip.\u00a0 The tip is 1.8 mm diameter and has three cutting flutes.\u00a0 It is made from 440C surgical stainless steel.\u00a0 The tip geometry is created by rotating the rotary axis\u00a0180 degrees synchronously as the wire follows a curved path 4 mm long.\u00a0 The shank is 0.8 mm diameter and is left rough since there was no need to incur the expense to wire it to a fine finish.\u00a0 Overall the part is 25 mm long.<\/p>\n<\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"
