Medical Machining and Metalmite

Metalmite has been looking into the medical machining field for some time now. CNC machining is the process used to manufacture different types of medical tools such as scissors, clamps, surgical knives, syringes, and others. Medical instruments manufacturing uses advanced machining processes that help in producing precision medical tools and equipment required in the medical industry.

Medical machining involves the machining of metal parts, which are extremely intricate and are mainly made from special alloys, stainless, or titanium. Different techniques used in medical machining include 5 axis milling, 6 axis machining, wire edm, and electro etching. Chemical etching machining process is mainly used for producing typical precision medical parts. The medical industry has very strict guidelines and regulations for how clean the environment must be as well as quality documentation. Many of the medical products must first be proven out with a working prototype and then followed up with the small volume production run. This is where Metalmite is able to excel on both sides of the spectrum.

  The need for medical machining ranges from contract precision manufacturing of implants and surgical instruments
to cardio/neuro stimulation, orthopedic, interventional, and drug delivery. As well as Prototyping leading to volume production and cleanroom, packaging, and labeling requirements. The minimum quality rating are ISO 13485 and ISO 9001 registered firms.

Saving Time and Money for our Customers

LarryBinkowskiphotoMetalmite has worked very hard to save time and money for their customers over the years. Everything from adding 5 axis machining to CNC screw machining centers that have decreased our leadtime by half.  On this job in the picture we have manufactured these aluminum plates for over 10 years. The original setup was on 3 seperate CNC Machining centers with 3 serperate operator’s. After a few years of having the job repeat, we were able to maximize our CNC Manufacturing procedure’s. We currently use one CNC Machining center and have 3 separate clamp systems that hold the the part through the 3 separate operations. As a one stop machine shop we work hard to save time and money for our customers. We have used several methods learned from our high speed milling techniques that have further increased our efficiency as well. The part has decreased in cost by 50% to our customer and they are thrilled with the results during these trying times.  Metalmite works hard to offer World Class Quality, Service, and Delivery at the RIGHT Price!

High-Speed Milling

2009-9-1-1-5Axis 001Metalmite has made the jump to high-speed milling recently. Metalmite was the first machine shop in Michigan to purchase the new Mori Seiki NV1500 DCG Milling machine. People from all over have inquired as to how it performs as there are not many to see in the USA. Metalmite was told that there were only 8 machines in the USA. The machine has an amazing accuracy rate and the 27,000 RPM spindle makes cutting hardened stainless seem like nothing. High-Speed and Hard Milling are now being employed extensively, and those shops not effectively implementing this technology will eventually fall by the wayside in this highly competitive worldwide marketplace.

An overall reduction in production time of greater than 35 percent is regularly achieved — Less Time “in-process” means less cost!

Also, the very fine and smooth finish right off the machine may make it possible to virtually eliminate very costly and time consuming manual polishing and bench work.

High speed machining involves taking milling passes with smaller-diameter end mills at very light depths of cuts, but taking these passes at high feed rates

Hard Milling allows them to skip several time-consuming, labor-intensive steps in the machining process.

Hard milling is a much more reliable, predictable and productive process,

Hard milling is an offshoot of high speed machining techniques.

The essence of high speed machining is taking many light cuts at closely spaced step-overs, thus leaving minimal cusps between passes. The goal is to create an as-machined surface that drastically reduces the need for subsequent processing.

Routinely achieving surfaces finishes, as good as 8 to 10 Micro-inches, “Ra” (Roughness No. N4) with hard milling when needed. Because the steel is already hardened, subsequent heat treating, stress relieving, finish machining and grinding steps become unnecessary. More importantly, the process also replaces many costly steps that would otherwise require final processing.
