The top cut on the seat (usually 30 degrees), establishes the outer edge of the seat and helps turn flow into the combustion chamber. A 60 degree bottom cut sets the width of the 45°seat. The 45° exhaust seat is deliberately kept inboard of the outer edge of the valve otherwise hot exhaust gas will eventually erode the edge of the valve.

The whole point of using a Bridgeport to cut seats is because it has more heft and stability to reduce deflection vs most of your average SG machines. In theory its more of an issue when using an end mill or such to take cuts, cutter runout is not going to work in your favor. Pete Graves. CPMotorworks,Inc.

The newest addition to the 3D Fast Cut™ system is a ball head specifically designed to work with Sunnen SGM tool holders. This ball head uses the popular .375" top pilot, so it's easy to find new pilots as needed. The tool holder channel measures .500", so it is designed to fit Sunnen SGM1055, SGM1090 and SGM1115 tool holders.

The Seri and sunnen VGS20 are the most common seat cutting machines, they work dandy on MOST engines, and fast and repeatable. Older floating table seat cutting machines can be upgraded with new stuff like carbide pilots to make them work almost as good as the newer machines.

Newen makes a specialized machine. I'm referring to the typical type of CNC mill found in a machining job shop and using it to cut valve seats. Examples would be: vertical mill (Haas, FADAL, Mitsuura, etc.), a 3 axis reftrofit knee mill (like a Bridgeport), a bed mill (What Rottler likes to use), a horizontal mill, etc. needforspeed66gt.

Set the drill press for low speed and start the drill. Holding a mill file against the table, I carefully swing the table toward the valve until the file is just touching the valve face. A mill file has blades that run the full width of the file. A rasp has teeth. You must use a mill file, not a rasp.

You use a pilot and a seat and guide machine . It could be done on a mill too ( I don't know if they use a airfloat table on the milling table) . I have a sunnen vgs20 .

According to their data and my measurements, I will need to cut down the valve spring seats to accommodate the proper installed height of the springs. Comp makes a tool (PN 4733) with an arbor (PN 4732) to do just this, with just a hand drill. I watched a Comp video on Youtube demonstrating it.

EQUIPMENT OPTIONS. So if dry milling is the way to go, what type of surfacer should you get? The basic choices boil down to buying or leasing some type of dedicated surfacer, or moving up to a multipurpose CNC machining center that can surface, bore, drill, tap, chamfer and clearance and also port cylinder heads if you opt for a full 5axis CNC machine.

A simple hand tool that uses the valve guide to center the cutting tool is a terrible idea. You will never get the seat face concentric with the guide bore. Most likely you will do more harm than good. The end result of using such tooling will be poorly formed seats, out of round seating faces, and none concentric to guides.

A perfectly concentric valve seat is the result. The 3angles can be clearly seen, the inner angle is to relieve the throat, the middle angle is the seating angle and the outer angle is a radius angle blended into the combustion cut depth is noted so that the remaining seats can be cut to the same depth, ensuring consistent valve spring loading valve clearances.

The exhaust is also harder to cut on the clones if I am not changing the exhaust seat. With the mill and the 3 angle cutter it takes a lot of time getting the pilot in alignment with the spindle driver for the cutter. One that is done the seat comes out perfect, I still do lap with 800 grit to see where the seat is.
