Some surfacing equipment can be set up and mill a head in five minutes or less. What's more, if you are resurfacing several identical heads in a row, the actual milling time may only be a couple of minutes. It all depends on the speed of the cutter head, the number of tool bits, the feed rate and how smooth you want the surface finish to be.

Yes, dissasembly is required. When they mill they will make 89347652983479518743 little tiny metal shavings. And those will get EVERYWERE. You won't be able to get them all out if the head is assembled.

Head and Spindle. The head of the mini-mill is essentially identical to the headstock of the 7x10 and 7x12 mini-lathe. A separate casting mounts the head to the column, but inside the head …

3. Cutting heads quite depends on the head and the deck thickness. Some you can cut .185 nad some you can only get .005. A general rule of thumb for street engine is a .030 cut or more reqiures correcting the intake face and spoting the bolt holes. Race it, break it, fix it and repeat. Save.

This mini mill head assembly has an R8 spindle. The motor controller is a PWM variable speed controller with overload protection and a zero-speed start interlock. Motor: 350 Watt (0.47 HP) Low speed: 0-1100 RPM. High speed: 0-2500 RPM. Drilling capacity: …

For porting cylinder heads and making complex 3D components, the workpiece and tooling head both have to move so the tooling can follow complex curves and circular motions. This requires a 5-axis CNC machine (the 5th axis being the circular movement of the tooling), and software that can program the intricate movements.

The peak dyno numbers for these heads before milling are 289.5HP at 5400 rpm and the torque is 333.8 lbs/ft at 3900 rpm. The heads are then milled ~0.050" which gets the combustion chambers down to 67.3cc for a 9.04:1 SCR. The horsepower in this format jumps up to 295.4 at 5300 rpm while the torque increases to 338.5 lbs/ft at 3900 rpm.

The combustion chambers are filled with the desired volume in fluid, depth checked to the head face and then skimmed on our CNC milling machine to give the correct volume. The cylinder head is assembled with a set of our race-proven 21NS plasma-nitrided valves, double valve springs, new valve retainers and CNC-machined collets.
