Subtractive Manufacturing 

In March of 2015, we stepped into the world of precision machining with the addition of 3 brand new pieces of sophisticated machining technology. First into the lab was our Citizen Machinery Cincom L20 which gives us screw making capability that is particularly applicable to our medical research activities. It will also give us the capability of making screws that can be used in a nearly infinite number of assembly applications not limited to the medical field.


One of our most important research focus areas is on the finishing of additively manufactured metal parts. Using EBM or DMLS technology can achieve near net shape, but getting all the way to net shape is challenging. Precise finishing of metal parts is critical, and our next machine into the lab was our new haas Multigrind CA. From the haas website, “the CA offers remarkable travel ranges (X-axis: 630 mm; Y-axis: 345 mm; Z-axis: 430 mm), which means you can economically machine larger rotationally symmetrical or cubic workpieces. Depending on the grinding process, the CA can be equipped with grinding wheels with a diameter of up to 250 mm, and 12 wheels fit in the patented double-wheel changer…the CA also offers an impressive level of precision and efficiency in serial production processes.” In other words, we can really do some stuff now.


To complete our technological capability to produce precise metal parts, using “subtractive” equipment of the highest capability was essential. To that end we are now the proud owners of a new Mazak Integrex i-100ST. From the Mazak website, “The INTEGREX i-100ST advanced Multi-Tasking machine delivers maximum versatility and throughput for smaller complex parts. The machine combines the capabilities of a high-powered turning center and full-function machining center to produce parts in single setups…With full 5-axis capability, the machine easily processes fully prismatic parts from solid or castings (chucked or bar fed work), round parts, or sculptured parts such as aerospace components.” The addition of this equipment, combined with the machines above, make our CAMAL lab extraordinary in what we can do in the future.


We have been fortunate from our beginning to have an outstanding HAAS VF 3ssyt 5 axis machining center which has supported our metals work for several years now. The 3ssyt has been a dependable work horse, and will continue to be an important part of the work we do here at CAMAL.
