RFI: Bandsaws and vise wear
I have a buddy who is cutting about 2000 ft ea of 1.5 angle iron. 1.5 round tubing and 1 inch sq tubing on a Jet 7 x 12 H&V band saw each month. It is more cost effective for him to have an employee to cut the stock than have it cut by the supplier. The stock is cutting a groove in each face of the vise and the bed of the saw. The cost of replacing the vise jaws is small, the cost of replacing the bed of the saw is not so small. We were kicking around the idea of an abrasion resistant plate to attach to the vise jaws and the saw bed. Has anyone done this or what material would be suitable to do this? regards, Jim |

For God's sake he ought to be able to figure out what it is costing him
for equipment and labor and compare that to whatever the quote is from the supplier.

Making sure other people play nice and dont kill each other (and us) off in job lots is hardly empire building, particularly when you give them self determination under "play nice" rules. Think of it as having your older brother knock the **** out of you for torturing the cat." Gunner |

My fault. 1) It is much cheaper for Craig to cut his own stock than have it cut by the supplier. This is not the problem. 2) He is running 6000 ft of various stock through a Jet 7x12 band saw a month and the stock (not the blade) is wearing a groove in the cast iron vise faces and the the bed of the saw (this is the problem). As a small project, we were thinking about facing each of the vise jaws and the bandsaw bed with an abrasion resisitant plate. Neither one of us has a clue what material to use or if there is a better way to answer the problem. He has adjusted the deadman roller guide infeed and outfeed conveyors as best he can to prevent bedwear but still has the problem. Many thanks.

Why not drill and tap the bottom of the bed groove for a couple of
headless set screws, or countersink and use flat heads, to set to level?

I'd get a welder to restore & hardface the surfaces. - GWE

Ok, so the material is being dragged through the saw since the saw is
on an assembly line. The material is being pulled through it and this is causing the wear. I would think the best solution would be an input roller that can be easily raised or lowered a inch or two by means of a lever.

On Sat, 17 Sep 2005 13:46:49 -0400, with neither quill nor qualm, Ned
Simmons quickly quoth: In article , says... As a small project, we were thinking about facing each of the vise jaws and the bandsaw bed with an abrasion resisitant plate. Neither one of us has a clue what material to use or if there is a better way to answer the problem. Sacrificial mild steel plates that you replace as required. That would probably be the quickest and cheapest solution. 30 minutes to make a dozen, 5 minutes to change out a pair of 'em. OTH, I think your friend might do well to shop around some more for a supplier who will precut the stock. It's hard for me to believe that his man using a little manual saw like that can compete with a large automated machine in the hands of a vendor who wants the job. That could be the key. If the vendor doesn't want (or doesn't have the time for) the task, he'll triple the price for cutting. |
