I'm wondering what the general tolerance is for hole sizes.
I received an order today in which a few 0.125 inch were used, intended for press-fit dowel pins. The dowel pins are loose instead and I found that a #30 drill (nominally 0.128") passes easily through those holes.
It would help me to know what precision to expect.
I can just use slip-fit loctite for now, but in the future should I specify any special tolerance in the order notes (or elsewhere?), or have them drilled smaller and ream precision-diameter holes myself? I have low volumes so that wouldn't really be a problem for me either.

Our tolerance for holes, engravings, sizes, and thickness is +/- .1mm.
For your .125" drill hole, it would not be out of the ordinary to receive a panel with a .129" hole. If, however, you measure the hole with a caliper and find that the dimension is measurably larger than that, please contact us.

Thanks for the quick reply, Paul.
For what it's worth, these holes are 1/8 inch diameter, not 1/4. They are within that +/- 0.1mm spec though.
I thought they might be tighter, at least when using "standard" sizes. Do you use the closest metric drill when "inch" sizes like this are specified?
In any event in the future I'll be sure to make any lower-tolerance holes a bit smaller and ream them true myself.

Hello again Ed,
(I amended my post above)
When you have specific needs concerning really tight tolerance holes, it is always good to leave a note in the "Remarks for Production" box in the panel properties, or to give us a call.

Any chance you will be adding the ability to Laser Image/Engrave an anodized panel vs using an engraving tool and infill? This should be more economical and a lower cost for the customer while stillreatining the excellant machining you provide.

Hello again Jeff,
We do not foresee purchasing a laser engraver any time in the near future.
While the actual purchase price of an engraving machine is less expensive than a mill, the additional time of moving and positioning a piece of material in a second machine would wipe out any possible cost savings. The time taken to engrave text into a given panel is not generally cost prohibitive, and this process is completed without additional handling of the panel.

Laser engraving machine, using a laser engraving technology equipment for carving materials. Laser engraving machine is different from mechanical engraving machine and other traditional way of manual sculpture, mechanical engraving machine is the use of CNC machines, such as high hard just high hardness materials such as diamond to sculpt low hardness of other things. And artful and laser engraving machine is using the heat energy laser on the material to engraving, laser in the laser engraving machine is its core. In general, the use of laser engraving machine, broader and higher precision carving, carving speed is more quickly. And compared with the traditional way of manual sculpture, laser engraving engraving effect can be done very exquisite, no less manual sculpture of the art. It is because the laser engraving machine has so many advantages, so now the application of laser engraving machine has gradually replaced the traditional equipment and methods. Be the main engraving equipment. Is laser cutting/engraving processing technology :badgrin:

Any chance you will be adding the ability for Color Printing (natural aluminum) the Front Panel similar to your competitors?

There are a few layers to this question, so I will try to address them all as clearly as possible.
What we generally see offered by other companies is silk screening. Silk screening requires a fairly hefty investment with each new design, and it is generally only used when quantities are high. Also, silk screening is printed on top of the material, and it can be scraped off quite easily in many cases.
We are in the experimental phase of printing into aluminum (not on top of). This should offer an economical solution to printing a one-off prototype without a giant setup fee. This type of printing would also be less vulnerable to abrasion. Keep an eye out in 2011/2012 for more on this.

The Putting Green
If any part of your ball is touching the green, it is on the green. When your ball is on the green, you may brush away leaves and other loose impediments, but otherwise do not touch your line of putt. You may repair ball marks or old hole plugs, golfwholesale18.com but do not repair marks made by spikes or shoes before playing. You may not test the surface of the green by rolling a ball or scraping the surface. Always mark your ball by putting a small coin or other marker behind it when you want to pick it up to clean it or get out of another player's way.
