Dr. John Webster (aka Dr. Cool), of our partners at Cool-Grind Technologies, has designed a fantastic Grind-Loc based nozzle system for new WALTER Vision 400L & Power 400 wheel changers. John’s design accounts for all the following considerations:
- Unlike the earlier WALTER wheel-changer machines, it is difficult to reproduce the manifold locking system and create a more user friendly design that offers more ports
- The OEM manifold has 30 degree inclined threaded ports, which requires all nozzles to compensate for this angle. A common 45 degree elbow will not help. Cool-Grind supplies a 60 degree elbow as a standard item that creates a vertical 3/8″ NPT thread
- The OEM manifold threads are 3/8″ BSPP, which only suit the 10mm tube compression fittings supplied with the machine. Common 3/8″ NPT pipe fittings will damage these aluminum threads. Cool-Grind offers compatible 3/8″ BSPT brass pipe nipples of different lengths that are kinder to the OEM threads and have a standard NPT thread at the other end
- For tool grinding, the simple Cool-Grind nozzle setup requires the fluting wheel to be no bigger than 6″ OD
- The nozzle setup has to fit inside the wheel carousel and pass through the door during loading
