Medical Industry

MORESUPERHARD provides customers with prosthetic parts in the medical industry including hip joints, knee joints, spine, dental, etc., as well as processing solutions and superhard tools for various bone plates and connecting screws.

• Innovative solutions for orthopedic implants

  

  In the solution provided by MoreSuperHard for processing orthopedic implants, the milling cutter used adopts a unique wiper design, which eliminates the need for polishing and direct sandblasting after processing, thus saving processing time.

  The Meniscal is made of ultra-high molecular polyethylene, and deburring and large arc surface finishing are particularly important during the processing.

   

  The large arc surface forming fine milling cutter can make the processing cycle of this part <10s and the surface quality Ra<0.2.

  Compared with the traditional processing method of ball end milling cutter, the processing time can be reduced from 20 minutes to 20 seconds.

• PCD/CBN inserts for turning hip joints

  

  An artificial hip joint replaces the joint between the thigh and pelvis. It consists of three main parts: the femoral stem, the femoral head, and the acetabulum.

  Hip implants are typically made from cobalt-chromium alloys (such as ASTM F1537), titanium alloys (such as Ti6Al4V ELI), or medical-grade stainless steel (316LVM).

  There are milling cutters, drills and high-precision reamers used in the machining process, and standard PCD/CBN inserts.

  The inner and outer surfaces of revolution of the parts, including inner and outer cylindrical surfaces, conical surfaces, and spherical surfaces, can be turned by turning. It is most suitable for cutting titanium alloy and heat-resistant alloy materials, and the machined surface quality is high.

• Application of PCD/PCBN Tool in Bone Plate Machining

  

  Bone plate is mostly used in the repair of fractures. It has various shapes and is used in a large amount. The materials are titanium alloy (Ti-6Al-4V) and stainless steel.

  The main machined surfaces are profile surfaces, holes and chamfers.

  The conventional processing methods for holes and chamfers of complex shapes are:

  ①Hole processing

  ②Inner diameter forming processing

  ③Chamfering processing.

  At present, the end mill is used for helical milling of holes at one time, which greatly improves the efficiency and processing quality.

• The advantages of MORE's milling cutters when milling knee parts

  

  ▶Produce burr-free outer contours. The ability to further extend tool life allows for excellent machining quality when dealing with difficult-to-machine materials.

  ▶MORE’s custom end mills provide significant machining time savings compared to traditional copy milling strategies.

  ▶Maximize metal removal rates during roughing and significantly reduce cycle times.

  ▶Ball nose cutters are available in diameters from 3 mm to 10 mm. High rigidity and extended machining range of the tool.

  ▶MORE's durable end mills are specially manufactured for machining cobalt-chromium alloys for high metal removal rates and smooth cutting processes.

  ▶The end mill not only provides good machining quality for the inner wall of the bracket, but also chamfers the edge of the groove, thus achieving an excellent balance of productivity and quality.

• Application of PCD/PCBN Tool in Bone Nail Machining

  

  Bone nails are one of the most common orthopaedic implants.

  Because of the stringent requirements for good mechanical strength and biocompatibility, most bone screws are manufactured from stainless steel or titanium alloys and come in different thread designs, pitches and thread lengths.

• Application of PCD/PCBN tool in dental implant products

  

  With the improvement of people's living standards, more and more people begin to pay attention to the beauty and health of teeth. 

  There are three main ways to restore missing teeth in the dental implant system: removable dentures, fixed dentures, and implants. Dental implants are composed of three parts: implants, abutments, and crowns. 

  The implants are fixed on the collar bone in an "osseointegrated" manner, acting as an artificial root, and then connected to the upper crown through the abutment, thereby exercising function. 

  Compared with the previous two dental restoration methods, the dental implant system has stability advantages, no damage to adjacent teeth, comfort, and long use time.
