The unique TSG Rim Drilling Machine can drill all possible spoke patterns in the costly ultra-light carbon rims of the professional cycling world. Edco invented the drill principle, TSG developed the machine: from design to trial production in our own Proto & Pilot Production.
The TSG Rim Drilling Machine can drill at any angle and from the heart of the rims, partly due to the rim turn and clamp system. Whilst regular machinery only drills from the outside of the rims, the TSG Rim Drilling Machine drills the nipple gap from the outside, and the spoke gap from the inside. As a result it is possible to drill from exactly the right angle, so that the spokes are not being warped, and as such this decreases stresses on the spokes, and therefore increases reliability and strength. The machine is developed to drill 26 inch, 27,5 inch and 28 inch rims up to a depth of 9 cm.
The TSG Rim Drilling Machine must also be suitable to drill different types of rims. This was a big challenge, both in mechanical and electronic terms. A programmable spoke pattern generator was developed. The spoke patterns we develop can be loaded onto the machine’s sophisticated processor via a USB stick.
Being able to control the rim drilling in house has allowed us match the drill holes with the specific spokes used. This means there are no large gaps around each spoke at the point where it enters the rim, and unlike many other deep rims our wheels will not collect water as the spoke holes are tight to the spoke itself.
