Artificial hip joints generally consist of four independent parts: stem, ball, socket (or cup), and ultra-high-molecular-weight polyethylene liner that fits into the socket. As a joint prosthesis, the materials must have high strength, reliable chemical stability and safety, low friction but high wear resistance, and outstanding biocompatibility; therefore, difficult materials such as medical grade and surgical stainless steel, titanium, or cobalt-chrome are widely used.
Tungaloy presents a broad range of unique tooling and optimal technical solutions for CNC machining centers and Swiss-type machines to effectively and competitively machine difficult materials used in the medical industry.
AH8000 grade series is PVD-coated carbide grades featuring AlTiN nano-multilayer coating with high aluminum content developed specifically for machining exotic parts.
Using these grade inserts in combination with proper through-coolant delivery system such as TungTurn-Jet or StreamJet-Bar can heighten process security through increased tool life and better wear prediction.
MiniForce-Turn features cost-efficient double-sided positive insert with unique dovetail profile that securely interlocks with the matching profile of the insert seat for maximum insert reliability and process security.
Designed to maintain sharp cutting edge over an extended period of time, MiniForce-Turn insert generates low cutting force and excellent surface quality, while the double-sided feature offers increased number of usable cutting edges per insert for improved insert economy.
TungMeister exchangeable-head end mill system offers more than 13,000 possible head-shank combinations, enabling quick, easy, and accurate tool changes between various applications.
SolidMeister solid carbide end mill series offers a wide variety of sizes and geometries with sophisticated features.
Bone screws are one of the most ubiquitous orthopedic implants. Most bone screws are made of stainless steel or titanium alloys due to stringent requirements for good mechanical strength and biocompatibility and come in various sizes with different thread designs, thread pitches, and thread lengths.
Despite its seemingly simple structure, bone screws have a surprising amount of complexity in its design. To meet this challenge, precision CNC Swiss-style machining is the method often used to accomplish the designs that give bone screws the proper features and functionality for their end uses.
SH725, a PVD-coated carbide grade, is developed specifically for Swiss-type machining methods. Improved coating-substrate adhesion and hard coating layer provide the insert with excellent wear resistance and edge line security.
TungTurn-Jet toolholder system with precision through-coolant delivery capability enables coolant supply close to the cutting point, providing better chip control and longer tool life during the machining of difficult materials, while also allowing the application of significantly increased cutting parameters.
MiniForce-Turn features double-sided positive insert with sharp cutting edges. AH725 grade enhances the insert’s edge-line security and wear resistance, generating light cutting with long tool life. Tool stability ensured by innovative dovetail interlocking provides this challenging machining with process security, as well as cost efficiency.
