1) find a rack with 6 fastening screws (A series edge planning machine screw M20 × 1.5), turning them into one end of the cone with the top, screw the other end of retention, then the top part with a hacksaw in each saw a width of 2mm to 3mm gap depth and width to put it down flat screwdriver blade is appropriate, as shown in Figure 2. Then screw the top quenched processed in order to improve the hardness of its top.
2) Rack mounting surface to clean, from the installation position of starting point, the six screws with a screwdriver in turn screwed into the body of the top six screw holes. Note that the screws screwed into the top of the exposed height of 0.5mm is appropriate, try to ensure that the top contour.
3) Install section rack, rack datum requires close contact with the installed base, while the inner side of the rack mounting surface with screws on the top three good contacts with a copper hammer gently tap from the middle to both ends of the teeth of the outer side. So that the body three screws holes in the center position will be accurately reflected in the rack
4) Position rack in the first section to ensure the case will be put away Section II rack close to the same datum and ensure the installation of the base rack sticking real. Taken to a rack with the specifications for rack mounting, mounting rack and the first, two rack gear junction, alignment II rack is installed. Section II also pressed the rack; the rack with a copper hammer tap the outer side, inner side of the rack will mark the next three holes at the center.
5) ensure that the Section II rack position, remove the section rack, rotating the three screws under the top to be screwed into the rack installation of the third quarter with three screw holes, the following sequence as described above. So and so on, until all the racks with well, pay attention to the order of each section and mark the rack ready.
6) Label all the screw position in the rack, and then to its focus on the drilling machine, then you can install the rack.
