1. Difficult to process titanium alloy materials
90% of medical device implant components are made of Ti6Al-4V titanium alloy. Due to its light weight, high strength and high biocompatibility, titanium alloy 6AL-4V has become the most commonly used material for medical implant devices. Titanium alloy 6AL-4V is usually used in the production of medical parts for hip joints, bone screws, knee joints, bone plates, dental implants, and spinal connection components. Titanium alloy has the characteristics of work hardening. The relatively low modulus of elasticity makes titanium alloys more elastic than steel. Therefore, excessive cutting force should be avoided to ensure that the rebound of the workpiece is small. Thin-walled parts have a tendency to deform under tool pressure, causing chatter, friction and even tolerance problems
2. Reliable and compact machine tool fixture
Medical parts processing equipment needs to be able to process small and complex parts made of difficult-to-process materials (such as titanium alloy or stainless steel) with high accuracy requirements. For example, processing bone and joint replacement parts is quite complicated. Lemo has long been committed to the processing of high-precision, high-difficulty, and easily deformable metal and plastic parts, small and medium-sized batch production and manufacturing of light alloy and composite materials (such as aluminum alloy, carbon fiber, etc.) parts, and robotic parts procurement and customization services . Medical equipment parts and components have high requirements on material, processing accuracy, and surface finish, which requires high reliability of the processing system.
3. Stable and efficient machine tool operation
First, the requirements for machine tools are relatively high. Advanced medical equipment parts processing equipment such as automatic lathes, multi-spindle machine tools and rotary tables are completely different from the usual machining centers and lathes. They are very small in size and very compact in structure.
Second, it requires high processing efficiency. For the processing of medical parts, the most important thing is the processing efficiency, that is, the processing cycle. It is required that the blade can be replaced in the shortest time.
Third, in terms of the workpiece itself, it is very different from other medical device parts. Medical devices implanted in the human body first require very good surface finish, very high precision, without any deviation, and the precision must meet the processing requirements.
