The machine was finally ready for use in 2016 and took the load off my BF20 Vario. In the course of this, I developed a water cooler for Coollaboratory which then went on sale. In spring 2016, I started to tackle the project with the pneumatic tool changers. The goal is a tool magazine with up to 22 tools. The system is still not in use due to lack of time, but it is imminent. The tools need to be calibrated, the emissions need to be minimized ( oil fogger) and the spindle cooling needs to be completed. In March 2016, the engravings got an update. One can now have the engraving laid out at no extra charge. Green, yellow, blue, black, white and red are freely selectable.
Furthermore, I began to deal with the subject of air filtration system because due to grinding dust and oil mist in the air, the air in the room is heavily contaminated. In retrospect, this is one reason for my emphysema. And I was in my mid-30’s. I read a lot and also got quotes from companies. One company would have taken care of the problem for 8000€. Unfortunately, the budget was not available. Thus only a self-construction came into question. I started with a 200mm tube fan and a vacuum cleaner filter. This brought a clear improvement, but I was sure that there is still a lot of room for improvement.
At the same time new milling spindles came in for testing. All the spindles were put through their paces but the mass was found to be rather poor than good. More suppliers were sought and later found. The problem with many milling spindles is simply that they are no good out of the box. With almost all spindles the cone angle does not fit. Concentricity accuracies are not maintained up to 50%. There are leaks, overvoltages, the spindles are not grounded, screw connections are broken off and rusty inner cones have been found. Furthermore, gap dimensions where you could drive a herd of cows through. You get what you pay for… I sort out all my unfit spindles and deliver only excellent spindles to my customers. In 8 years there have only been 3 complaints! January 2017 I started to manufacture and integrate the tool magazine.
In spring 2017 I continued with the filter technology. H13 as final filter should straighten. Which was then also quickly accomplished. Looking back, the filter area of about 50m² is not excessive. Because a volume flow of approx. 1800m³/h is needed to extract all emissions. This corresponds to an air exchange rate of approx. 18. This is not extremely high, but it is very high. Companies that offered me to install an air filtration system recommended an air exchange rate of 8-10. I would never have been able to achieve this. I also made a suction shoe for the milling spindle of the large milling machine, attached it and extended the Z axis for another milling spindle. The latter is used for dry milling. For example, wood. -> Table tennis woods of the label Customblades.
After about half a year I got along with my small HSC milling machine so well that one can produce mirror-clear edges. However, my speed was so slowly catching up with myself. In the fall of 2016, I had to officially stop production. This is still the case today. Unofficially, however, production continues to the best of my ability. The already mentioned emphysema is only part of the truth. Accordingly, there are basically hardly any innovations from 2017. What I have created for myself over the last 10 years will be expanded from now on and only very slowly. Especially since you have to say that technologically nothing has developed further on the cooling market regarding GPU coolers. Existing cooling designs are only adapted to the cards. However, there was an optical update at the beginning of 2018, where it was possible for me to still use bezels. The beginning was made by the RX Vega 64 water cooler.
In March 2018, I started to deal with the topic of vacuum technology. After some tests a good configuration was found, where the vacuum table had to be adapted. My vacuum tables have all 4 lines for suction and a supply line of 1″. There is now enough air going through and the parts stay clamped, even when large areas are exposed.
In the meantime there were also some special designs like backplates and special material combinations. Among others also an IHS made of 935 silver and rebuilds of EK Waterblock lids. Furthermore, the quality of the coolers has improved steadily. Also in the subject of health and safety and emission elimination has done something. A new potent centrifugal fan with up to 1800cfm was purchased. From here on a turning point began. I focused much more on occupational safety and took more and more care of my health. The place in the sun moved further away from quarter to quarter.
