Figured I would share a video of a new toy This thing is awesome.
We upgraded the quality and performance of our Cylinder heads by moving to a new Newen CNC machine to do our Spec Miata heads moving forward. This machine insures the highest quality machine work possible held to the tightest tolerances. It is also completely automated so every head with be EXACTLY the same! After a few tweaks to the cad program the results on the dyno with the heads coming off the new machine are even better than what we had before! Things are looking even faster for 2017
This machine holds such tolerances and seals tighter than we have ever been able to achieve in the past, It cuts at 1200 rpm versus about 50-60 RPM of old stylee valve cutting machines.. A tedious processs for sure. This new machine uses a single point cutter and amazing precise and incredibly fast and accurate. We are able to cut all the cuts now in one pass. This used to require three different passes with three different tool. We could do each hole in almost half the existing speed but we take material off in small amounts as the core shift varies so much in the miata heads we have to make small passes. We can load unlimitted profiles, angles and contours into the machine with CAD and then cut it. The rules are specific now, but this machine still produces a much better finished product and most importantly, each is identical. Pretty excited to try this out. The first completed head will be in a contender car headed to the NASA champs.. we shall see.
