30Int and BT30 Tooling

Peter A Forbes · 2005-02-09T20:40:50+00:00

Having just bought the Beaver turret mill, I am now on the lookout for some30Int tooling for it. I have loads of 40Int for the A&S mills (1ES and 2ES) butsod's law says I have to get a vertical with something different!Talking with John S about the differences between 30Int and BT30, it seems thatthere isn't a huge difference, only the rear parallel section with the drawbarthread on the 30Int whereby the BT30 has only a straight taper body.Any thoughts/experiences from users on the merits (or otherwise) of using one ort'other??Peter--Peter & Rita ForbesEmail: Web:

Oh I hate it when a plan suffers perpendicular mammary syndrome!

The nice man from Linde (the new name for Lansing Bagnall) got back in touch with me. As you (correctly) surmised, it isn't one of the biggest pumps in the world! It is rated at 1.28GPM at 1500rpm (motor full speed is 2800 rpm). Minimum speed is 650rpm and it has a maximum pressure of 3000psi (he seemed to remember pressure relief set at

2400psi).

Looks like I have a limping tram as the motors I have need 6.5GPM for

650rpm!

Do you know any sources of cheap hydraulic pumps in the UK? I'd like to stick with the hydraulic idea if I can (after all I've bought the hydraulic motors now!).

Cheers

Talk to Peter Smith, he buys and sells a lot of ex-mod stuff and his auctions have has Plessey and similar pumps on there, he may well have something unsold.

I'll email you off-list with his details

I've several n shed, but postage would be a bugger. However don't forget, there's no free lunches and to drive bigger pumps, you'll need bigger motors..
