We need to hold a piece of steel approximately 40″ x 20″ x 1/4″ while machining the entire surface on a compound angle from corner to diagonal corner, to a final thickness at thinnest point of approximately 1/8″.
Is this possible using vacuum chuck technology?

The rule of thumb in vacuum workholding is the larger the part size, the better the results. If your strips are large enough, you might get better results. Also, grinding usually does not produce any lifting forces so you should be able to grind the parts as long as they are kept from moving sideways.

@ Daniel:
Ultimate pressure vs. CFM depends on your application. CFM tells you how fast a pump can draw a vacuum. Inches of Mercury determines how high of a vacuum is present. A high CFM (Cubic Feet per Minute) seems pointless in your application especially if you have a small gas discharge tube (several ounce capacity). Sounds like you want to go for maximum pressure.

hello, can you help me decide a better vacuum pump?
I have narrowed down to 2 options
when buying a vacuum pump, what are most crucial? e.g. ultimate pressure (pa), CFM.
And do they have to be as high or low as possible?

PS. am hopping to use it for experiments such gas discharge tube
Thanks
sincerely
Daniel

Dear Sir,

I am Mechanical engineering final year student .I am doing a project on vacuum chucks in a solar manufacture industry.i have some doubts.In that industry they have to grind small calcium strips.present they using vacuum grinding but its not giving good results.i got a small idea that if hold those calcium strips on vacuum chucks in more quantity and apply grinding operation means the out put may be high.I need your suggestions regarding this.I am kindly requesting you to give your valuable suggestions.

Thanking you

25 x 4.3 = 107.5 sq.in. x 14 psi = 1505 lbs of holding force. As long as your cutter doesn’t exert more than 1505 lbs of lifting force, you should be fine. And in wood, it’s not likely.

We would like to hold a wooden plank of size 25″*4.5″*3″ by a vacuum pump.The holding face would be 25″*4.5″.The holding force of the pump should be such that it can withstand a cutting force of the 1.5″ deep cut by a horizontal rotary cutter of width 5″ on its top face.

We would be grateful if you could advise us the ultimate power of the vacuum pump.
