Pekka --- End quote --- I don't see any reason why they wouldn't :scratch: I regularly grind smaller pieces on my surface grinder :ddb: --- End quote --- Castings are often rough and awkward shape and surface grinder is different animal than milling machine, isn't it? I would be too chiken to try. Maybe you could get away if you butt it against a parallel or something that has more "grip" on magnetic table/chuck AND a milling cutter that does not lift the piece? Rough pieces can be held in vice if some aluminimum/copper plate/angle/rod packing is used. I was assuming that there is milling machine, because "flycut" on opening post. --- End quote --- I'd agree with most of the comments :scratch: But as Pakrattuk had said that the bottom had already been fly cut, and working on the average size of a clamp I personally would clamp them on a magnetic chuck :scratch: as there will be a resonably sized flat surface for the chuck to hold :thumbup: saying that I could be wrong :( I will give it a try when i get home just to see if it does work :loco: |

This is interesting. Any chance of a picture and note about the chuck and milling cutter. Pekka |

Pekka --- End quote --- Yes :scratch: Once i get back from work in about 4 weeks time I'll set something up and try it :loco: Pictures will be included of :scratch: either a machined surface or the location of said part and the distance it travelled from the mill :lol: :lol: |

I have a set of these clamps mine have a drilled/tapped hole in the "heel" end so you can put bolt in and adjust it with a locking nut on-as for machining.I would say the underside which locates on job would need skimming,and maybe top -so the clamping bolt has a seating for the washer-thats it really-but if you wanted to a rough jaw vice sometimes known as a "Yankee" vice is for use with rough castings or irregular shaped jobs,such as this one.I would put one in vice and skim sides-then transfer to smooth jaw vice and complete- |
