The special fixture structure that the car machines the aperture inside thin wall canal is simple, it is easy to make, and the workpiece effect that treatment comes out is very good. The Kong Shi inside thin wall canal is machined in the car, because tube wall is thinner, stiffness is poor, when using chuck of 3 ungual automatic centering to hold clip, if clip is held closer, be out of shape big, if more loose, criterion cannot clip, although degree of tightness is proper, also overcome hard inside the error of aperture circularity, process weak data especially, cannot achieve technical requirement. Graph material of 2 graphs 1(: Organic glass) when the part that shows 1 times like the graph in production, press traditional method, with 3 claw chuck holds clip, circularity is very inaccessible requirement, percent defective amounts to 90% above, after the car that if the graph is shown 2 times,introduces machines the special fixture of the aperture inside thin wall canal, percent defective is less than 1% . When the car is machined, use canal of clamp of 3 ungual chuck to cover, the work that already had processed length puts a canal to cover inside, come back gland coming back into the canal to cover next have work axial impaction, again the circle inside the car has normal treatment, finishing and regressive give gland coming back, exchange workpiece the head, same method machines reoccupy another end. Structure of this clamping apparatus is simple, it is easy to make, and the workpiece that treatment comes out, the effect is very good, satisfied technical requirement completely. CNC Milling
