The typical machining procedure for all seats is a 3-angle valve job, the standard being 30, 45, and 60-degree angles. Similarly, intake and exhaust valves themselves must be reconditioned. Standard valve reconditioning involves refacing (grinding) valves on the 45-degree cut that contacts the valve seat.

Bridgeport set up for seat and guide work. Post. by wedge1 » Sun Dec 26, 2010 5:07 am. Hi guys, great site. I purchased a real nice late 80's series 1 bridgeport mill. It is a three phase unit with the variable speed set up. It has a bridgeport brand. powerfeed on the x axis. The table is about 48'' wide.

The valves must seat perfectly for the thouh of a second they contact the seat during the power stroke, correct valve grind will accomplish this. Don't forget, for every power stroke, there are three other strokes that have to be coordinated by the valves and pistons. Intake, compression, power, and exhaust. These valves are busy.

The Grinding head longitudinal moving and vertical moving are controlled by servo motor with high precision ball screws, the vertical moving is also equipped DRO. & linear scale for grinding/milling feed. The spindle speed can be controlled from 150 to 1400 rpm, so that the machine can be used for any type of machining application (milling and ...

Wet grinding can achieve high quality surface finishes but it's a messy process compared to dry milling, and it works better with cast iron. ... and a valve-and-seat machine for machining valve guides and seats, and a valve grinder for refacing used valves (unless you are buying new or reconditioned valves).

Some can be mounted on the cam box face, while others with an angled cam box have to be jacked up until the gasket face is level before machining. Rigidity is the key both in mounting the head and also with regard to the cutting tool, as on some heads you will be cutting both alumium and hard valve seats, which can cause the tool to skip.

As you can see, the three-angle valve job allows air to flow smoothly across the seat and valve face. Step-27: Examine the Angles. When we rub the valve face into the freshly ground seat, it scribes a line in the valve face. This shows us where the valve contacts the seat. Later, we'll grind the valves to match the new seats.

I saw an Underwood facing attachment used to regrind the valve seats on the locomotive above. The tool was made for steam dome cover refacing but adapted to that use. Steve Butler has a portable milling machine from 1906 we used for milling key slot in axle for the Polson #2. One of the neatest bolt on machines I have ever witnessed.

I would suggest hiring a shop with a serdi type machine/tooling to do the cutting---3 hours at most to get the seats cut to size and all at the same depth, as practicable. I finish the seats with a wet grinder to get a mirror finish but that is not always necessary, but do vacuum test the valve seal during assembly.
