High precision drilling Depth adjustment stopper High rigidity that the drill does not shake Quick attach / detach mechanism which can fix the drill vertically (Used for withdrawal etc.) Prepare slide rails Type that can be separated Temporarily attach the slide rail to the movable strut Assemble it on the flat desk as possible (to match the bottom of the support with the slide rail) Since screwing is performed, pull out the moving part Drill holes and fix with wood screws Temporarily fix the reinforcement to the support Drill two screw holes
(you know the meaning when gluing) Remove the screws Remove temporary fastening tape and apply adhesive Join with screw hole as guide Screw in several places emporarily fix the support on the fixed side Temporarily fix according to the reinforcing material on the right side of the screen Temporarily fix it according to the reinforcement as well Extract support on the fixed side Join with wood screw In this state, the movable side and the fixed side support column rub against each other and the movement is bad · · · Sanding the contacting parts The corner of the guide rail has a burr on the manufacturing side.
Since it is based on an assembly standard here, it is filed Check right angle Slightly misaligned Paste paper and fix it Adhere the fixed side support (adjusted earlier) to the drill board Fix it with a right-angle ruler as a guide (guide is guide rail) Bonding is done so that it is perpendicular to both X axis and Y axis (This is the most important) Check Fixed support on the opposite side is bonded based on the bonded support Naturally, this side will also be vertical Join the reinforcing material to the fixed side support Make a drill holding ring Drill holes in the center of the ring Make a holding ring of a drill with a circle cutting jig of a trimmer (if you do not have it, you can substitute a hole saw etc) If the drill fits perfectly OK! Cut excess part Join the drill ring.
However, it can not be fixed horizontally as it is Adhere using parallel pieces of wooden pieces Reinforce Reinforce with screws Reinforce the drill ring with screws Adhere aluminum plate (parts of depth adjustment mechanism) To install the insert nut, make a counterbore Press-fit the insert nut Paste the scale Reinforce with screws Making a detachable mechanism Join with a hinge Attach the lock Set the drill Because there is a gap "now" has no meaning Chuck a long drill Confirm vertical Of course, it is not vertical Fine adjustment using the clearance of holding the drill You can adjust this far by hand Epoxy paste Put the putty on the attachment / detachment mechanism and press it against the drill (We make scaffolding with wood screws on the take-out mechanism so that putty can not come off) Open after hardening
（Putty does not adhere to soft rubber） Check if vertical processing is possible Use a 2 mm drill Face side Back side
It is perfectly matched with the score line Depth adjustment mechanism Hit the drill tip against the object to be processed At this time, the memory becomes 0 point Move the memory to the desired depth and fix the stopper Drill to stopper position For the setting of the depth of 10 mm, the actual measurement is 9.14 mm
Since the tip of the drill is not a pin angle, it is about 1 mm shifted
