I have been thinking of utilising the DRO of my mill to rivet pressing. The punch would be held by chuck of the mill. ?However the problem was how to hold the die in place. I fixed the die on the table of the mill in case of existing rivet press. Obviously in this arrangement the table cannot be used for rivet positioning. The die must be straight below the punch all time. My solution is to hold the die by U-shaped rigid frame having concentric holes for punch and die and fix the work to the table for free movement.


I ordered the material 16X16mm black skin mild steel. The minimum order was 6m, but I needed only a meter or so. I may never run out the material in rest of my life. Anyway this material is good size to make various tools.


I cleaned out the material to 15X15mm.


Finished parts for U-shaped frame.


The frame was assembled after aligning the hole locations by SUS taper rod.


The frame can move around on the table by the punch fixed on the mill chuck. I made the depth of the frame as 120mm, since supposed width of my work might not exceed 100mm.


I also made T-nuts for work fixture. I cut them out from 16X16mm.


Finished T-nuts.


This is the overview of the rivet press. The work can move freely and accurately against the punch and die on the U frame. I used up 6mm silver steel and the punch is tentative SUS rod.


I tried pressing rivets using DRO function. The upper left is rivets in 2mm pitch in 45 degrees. The right bottom is seven rivets on a 12mm diameter circle.

早速DRO機能を使ってスチロール板にリベットを打ってみた。左上が45° 2mmピッチ。右下が直径12mm七分割。

To perform the straight pressing arrowed button and type in length, angle and number of stops. All stop locations are calculated by DRO automatically.


It is the same on the circle pressing. Specify diameter, starting angle, ending angle and number of stops.


To jump around the stops just press arrowed buttons and move the table until X and Y reading both go to zero. Very easy and accurate.
