it's cool how the tool is capable to creating a mirrored version of itself and then morph back ot hte original, when are we going to see that technology elsewhere?
I work with Sandvik since 12 years very close together. I have customers all over the world and I got always great support. I always got the tools which I want or designed. Now I do support and training for machine shops and very often I have to advice my customers to get a tool from Sandvik. Of course sometimes I make an advice for a different brand, because I always try to choose the best tool for actual work.
When I worked at "The Rover" the crankshafts were milled and ground. The grind was done in three stages with in-process gauging. Some cranks that were shared with Honda were made on a robotic line made by Carl Schenk of Darmstadt Germany. Rusty iron would be loaded on at one end and mirror finished cranks dynamically balanced would come out at the other end. All history now. The big grinders had 3 foot wheels trued by diamond picks after every 20 cranks. All 5 mains were ground at 1 pass.
thanks for posting this. Gives some options otherwise not realized. Your Sandvik 210 with the 1030E inserts (high feed mill) eats crankshafts for lunch! Great tool.
@running307 How does a machinist know when to just polish the crankshaft or to grind it and if he sells the bearings for that crankshaft is the machinist expected to use a micrometer on the camshaft to make sure to match up the bearings to the crankshaft tolarances?
You will grind it if it is scored or out of round. Yes Mic it. You need to assemble it to check for clearances, like .003" depends on the motor combo. Any scratches? grind it, then polish. IF its smooth, round and in tolorance you have the crank grinder just run the polish tool over it, a hand held machine that spins a special emry tape. clearance for the mains and the rods are ground in the crank. The rods and main caps are factory set clearance 2 hold the bearing "crush" tolorance. Good luck
Also, look up "Plasti gage" . You will need that to check the final clearance in the main and rod journals. Its a smal strip of plastic that deforms and holds its size, similar to dental floss. Lay it on the bearing, assemble the cap and tighten. Remove the cap and use the supplied thinkness gage to match up , and wham, you have your measured clearance. Easy enough right?
This is not for PRODUCTION MACHINING of crankshafts. It may be good for one off 's , but, spend some time in an automotive machine shop, and they do not machine crankshafts in the method. Auto companies use BOEHRINGHER or KOMATSU machines, and use a mlling or turn, turn broach method of machining.
I am sorry to hear that you do not like Sandvik Coromant tools. Many companies rely on us to provide the tooling and solutions that make them the most productive. That is the reason Sandvik Coromant is the number one milling company in the world.
I'd have to agree, the tools that we use from you guys on our cnc's are incredible and extremely durable. They can take a serious beating. good job sandvik.
I've heard of people speak about under cut and fillet radius on the journals. What is an under cut, is an under cut what you have here?

@david880brown
The 3th tool in this video (V-shaped insert) does an undercut. The fillet radius is the radius of the undercut....i think.
