New Vises Decrease Part Setup Time
During heavy milling operations, parts tended to creep upward and out of alignment within the vise jaws at this shop in Minnesota. Small chips got imbedded between the part and vise jaws, causing all kinds of problems. The company couldn’t operate its new Bridgeport VMC 1000 XP3 to its full potential on this part project, so the company's owner looked for a better workholding solution.

Are You Medical OEM Material?
As the baby-boomer generation inexorably falls apart, screws, plates, rods and less invasive surgical tools are increasingly available to put "humpty" back together again. A question for many precision part makers is, "How do I get into the medical machining game?" To find out, we talked to a major OEM about its supplier selection criteria.

Forming Hex Holes For Bone Screws
Close tolerances and quality surface finish are critical in successful medical machining. To meet such requirements in broaching titanium and stainless steel bone screws, with machined depths ranging anywhere between 0.080 and 0.150 inches, Hassay Savage Company (Turners Falls, Massachusetts) has recently developed an indexing-broach process using four-point or two-point punch broaches for use in Swiss-type CNC lathes.

Implanting Productivity
With the new software, programming is done off-line at the company with completed programs being sent to the machine. As result, setup time is reduced because it takes very little to prove out the program at the machine. Before implementing the system, a lot more time was spent at the machine writing and editing the program before the first part was made.

Complex Angular Dental Implants...on Multi-Axis Automatic
Just like a car or a machine, the human body benefits from the technological progress of small parts turning equipment. Precision and stringent requirements for safety and stability are essential in the medical industry. In fact, the demands made on surgical screws (bone screws, maxillary-facial screws, implants and so on) and bio-implants can be much greater for the human body than for many industrial and commercial product applications.
