What is a machine ready blank?

A machine ready, custom cut and ground blank is time and effort saved. You determine what dimensions and tolerance that will best reduce set-up, milling and machining time for your most important jobs. You pass that need on to us. We deliver flat, square and parallel blanks you can load with the comfort of knowing every piece will be equal.

How is this achieved?

Through precision cutting, Blanchard grinding, double-disc grinding and/or duplex milling.

Why take on the extra up-front costs?

  1. Reduce premachining costs
  2. Free up machine operators to prepare for the next job.
  3. Use less experienced machinists to oversee jobs using our blanks, saving your top talent for the toughest jobs.
  4. Cut part production time, allowing you to make more parts, or move through jobs faster.
  5. Reduce liability and part loss based on clamping errors
  6. Save money in the long run.

The Value of Implant Grade Alloys

More body jewelers have seen the value of using implant grade metals, like ASTM F138 316 L VM Stainless Steel, for products that will be worn in or on the body. These alloys are certified to an ASTM "F" specification, which when applied to metals, signifies that the quality of the alloy is acceptable to be used in a medical application. Some of these "F specs" indicate implant grade, while others indicate surgical instrumentation grade. It is important to make sure that the material used is to the implant grade. These grades go through an additional process called "vacuum melting" (the "VM" in 316L-VM) which not only removes impurities, but in the case of stainless steel, allows for a better surface layer on the material. This layer prevents the leeching of elements, like nickel, into the body. Very important for people with nickel allergies.

"Surgical Steel" refers to a variety of alloys. Some of them are used for body jewelry, but only a few specific grades like ASTM F-138 are proven bio-compatible. The term "surgical steel" often simply means that it is instrument grade--used in scalpels, hypodermic needles, and any other use that involves only temporary contact with the body.

Implant grade alloys cost more then lesser quality material, but it amounts to a fraction of the price of the finished product. Considering the benefits to customer confidence, marketing possibilities, and the image of the jeweler, price isn't such an issue.

Nickel Sensitivity

The EEC Nickel Directive is a regulation that requires a low rate of nickel release for all materials used for accessories that have direct contact with ones skin. Since allergies to this element are common it is a good idea to invest in a product that is low in nickel, or is proven to not release nickel into the body.

Commercially Pure Titanium is also ideal for people with concerns about nickel sensitivity. CP grade titanium can be anodized to create jewelry of different colors without affecting the safety, and is certified to ASTM F-67. We also carry Ti 6Al4V ELI that is ASTM F-136 compliant as a stronger implant grade material. 6-4 ELI (extra low interstitials) is commonly used in artifical joints and permanent spinal repair.

Ask for Mill Test Reports

M. Vincent and Associates is dedicated to the satisfaction of our customers. We only sell material that will last, therefore we recommend investing in material that has implant grade specifications, such as ASTM F138, when purchasing material to put in someone's body. Insist on mill test reports when you are dealing with someone's health. This insures that the material you are buying is traceable to the originating mill and is the authentic product you intend on using.

Give us a call when you need 6AL-4V ELI titanium sheet. We can supply very thin material rolled all the way down to between .004" and .014". These foils are in addition to a ready supply of all standard sizes up to .125" thick.

Have you found the perfect alloy for your needs, only to have metal distributors ignore your quote requests? Maybe they've gone to the trouble of "no quoting" you, but haven't explained why or offered any alternatives. Have you heard the dreaded words "I can get it for you, but you're going to get (and pay for) 1500 pounds more than you want"? Those perfect plans with the perfect alloy are now just a lot of wasted effort.

We're here to help you avoid this situation. We're more than just a stocking distributor, we're the company that has always exhausted every possibility when sourcing materials for our customers. This has given us a deeper knowledge on the widest range of alloys than our competition. We can tell you which dream materials haven't been in the commercial distribution network since the day they were first invented. We can offer advice on which material will come closest to your ideal alloy. An alloy to get you through until you feel confident that you will go into full scale production, or an alloy to replace the one you were counting on.

Often times we can even walk back into our warehouse, pack up a few feet of some exotic alloy and ship it to you the same day. Fully certified, with mill test reports.
