Our serdi valve seat and guide machine. This is my bread and butter for cylinder head work . Seat installations, throat cuts for porting, chamber work, and valve jobs
Cool machines!
Is the valvejob the last step after all porting has been done?
So the Serdi machine can do all types of valve jobs? 3 angle/5 angle?
Ive heard of a "radius" valve job but I don't know what that is. I assume instead of angles cut, its a radius instead?
The valve jobs is one of the last steps in cylinder head work. With the Serdi virtually any valve job is obtainable with the correct carbide cutter. We use different cutters with a variety of angles and seat widths to match the intended purpose of the build. If I get a chance I'll try to picture document the process of a cylinder head from start to finish. The picture of the cylinder head above is a world apart from what it looked like when it first came in I'll post a picture of the before shot I have.
I have tons of cylinder head machining questions.
Different things I've heard over the years but either didn't.make sense or contradicted what someone else said...
Are you ready? Lol
very nice Mach1n1st !!! We have been looking into the centroid lately. how do you like it? we have 2 doosans and 1 mighty viper as well but wanted to get our hands on the centroid for dedicated cylinder head work.

Love it. Well worth it. Payback is easily done in 5 years.
Blanket post. Most of the machines in ine photo. Axe pressure tester, serdi 3.0, sunnen cap grinder, rod hone, sv10 cylinder hone, manual lathe, t&s cram balancer.
Our newest addition Sunnen SV20 verticle hone.. really excited to play with this. We also received our new Kaeser Air Compressor,I will post a picture of that monster later.
Dont remember the exact numbers since we purchased the machine a few months ago but we will be using a coolant based lubricant as opposed to conventional honing oil to be able to keep the cylinders cool , so the tolerances were supposed to be even better than they originally advertised which is supposed to be better than the sv and ck 10 due to the automated dwell time. best part is since the block will not get super hot like it does with honing oil the cylinders will have better repeat-ability in tolerances between all cylinders. here is just some of the info from Sunnen
New large-part honing machine for job-shop volume drives diamond abrasives with a linear vertical stroke for ideal bore geometry
July 2013 – The new SV-20 honing system is the first competitively priced large-part machine for job-shop part production with a true linear, vertical, servo-stroking system to produce precision bore geometries on compressors, oilfield components, automotive/truck blocks and similar parts. Ideal for job shops and repair facilities, the SV-20 is equipped with a variable-speed 15-550 rpm, 4.1-kW (5.5 hp) spindle motor, powerful enough to drive two-stage, metal-bond, diamond abrasives for short cycle times with high accuracy and minimal labor. The
SV-20’s linear stroking system keeps the honing tool concentric with the bore throughout the full stroke length to produce a consistent diameter from top to bottom of the bore. The machine's work envelope of 915 mm x 1015 mm (36" x 40"), front-loading design, and weight capacity up to 680 kg (1500 lb) combine for versatility in processing a wide range of large parts. The SV-20 can be used to hone bores with inside diameters from 19-200 mm (0.75-8.00").
The PLC-controlled SV-20 utilizes a color touch screen, with a toggle switch to jog for fast setup. The swiveling operator panel can be adjusted for viewing from a variety of positions. A hand wheel on the machine allows left/right positioning of the column on its 760-mm (30”) X-axis. The machine comes standard with a 208-litre (55-gallon) internal coolant system equipped with two standard canister filters.
The SV-20’s rotary servo tool feed system can be used with two-stage hone heads to complete roughing and finishing without stone changes for faster processing times. The machine is compatible with all of Sunnen's past and current tooling for CK/CV/SV-series machines, including diamond abrasive hone heads and brushes, GHSS single-stage hone heads with CBN or diamond abrasives and brushes, and GHTS hone heads for two-stage honing with CBN or diamond abrasives.
The SV-20 is available with a 400V/50Hz/3Ph or 460V/60Hz/3Ph electrical system. Options include a T-slot base, manual rollover cradle for engine blocks, and sump pump to allow connection to an external coolant supply.
