The reason I want the air closaer.
I thought I made it clear but obviously I didn't. I don't want to stop
the spindle when changing parts. The lathe's hydraulic closer will only operate when the spindle is stopped. So the spindle must be stopped to change parts. There isn't even a parameter I can change to make this happen. I know because I looked and because I asked FANUC and MIYANO. Besides the time it takes to stop the spindle it also uses a lot of energy to start the spindle each time. I also need a dead length collet setup. Which means that if I use my Royal air collet closer I will also need to spend $200.00 for a Hardinge dead length collet assembly. Plus, the Royal closer is only good for 1500 RPM. I want 4000 RPM. Since I already have a nice dead length air closer that I can easily mount to the spindle, an Eaton rotary union good for 4000 RPM and air at 150 PSI, a solenoid operated valve, a power supply for the valve, and switches, all I need is a way to get power to the spinning valve. Unless sombody has a complete air closer system good for 4000 RPM that they want to give to me I am going to order a set of alternator brushes for 17 bucks and make a slip ring setup. Eric |
