On slide unit, the cross slid platform is nc sliding table, or the X is respectively connected with digital display differential head to slide unit and the Y-direction slide unit.
8. the detection means of cutting tool regeneration production bar plane verticality as claimed in claim 7, it is characterised in that：
The length direction of the locating slot be X to.
9. bar is detected with the detection means of bar plane verticality using cutting tool as claimed in claim 7 regeneration production
The method of plane verticality, it is characterised in that comprise the following steps：
Step 1, the bar two of the processing of milled end face is taken, is put into the locating slot, and by the two bar locating clips
Tightly, stick together the processing end face of two bars；
Step 2, the operating desk is positioned by the cross slid platform, make the border line and described ten of the two processing end faces
The Y-direction line overlapping of wordline；
Step 3, the microscopic observation unit is adjusted, so as to clearly observe the summit of the border line of the two processing end faces；
Step 4, first bar is rotated around own axes, observe the border line of the processing end face of first bar
Summit and the cross hairs Y-direction line between X to spacing, regulation to the X stops to first bar during spacing maximum
Rotate；Same mode operates second bar；
Step 5, the X is adjusted to slide unit, make the outer of the Y-direction line of the cross hairs and the processing end face of first bar
The summit of edge line is overlapped, and the X is reset to the mobile data of slide unit, then adjusts the X to slide unit, makes the Y of the cross hairs
Overlapped to line with the summit of the border line of the processing end face of second bar, read mobile datas of the X to slide unit, will
The mobile data of the reading divided by 2, the processing end face of two bars is produced relative to the perpendicularity of bar axis.
10. method as claimed in claim 9, it is characterised in that：Repeat step four and step 5, obtain multiple two bars
Processing end face relative to the vertical degrees of data of bar axis, average.
