Medical Parts Inherent Stability
Recently introduced some cutting tool concept to the medical industry, the processing of small parts more efficient, and significantly enhance the production efficiency. Especially for small parts processing slitting machine tools have been further developed, but also led to the cutting tool continues to introduce new, which can provide maximum utilization of machine tools required for high performance. Some cutting tool areas have been lifted to new performance levels - the screw spinning and the use of high pressure cooling (HPC) functions are two prominent examples of turning.
As in the case of competitive pressures in the manufacturing sector,Medical Parts slender screws (such as bone screws) that produce high-performance metal materials in large quantities also increase. Suppliers of the medical industry are usually faced with such a situation in which the processing volume of such products is increasing, and thread whirl milling is already established processing methods. The inherent stability of the process makes it very suitable for mass production and processing of demanding metal materials. The cyclone milling can be used with a more robust cutting edge, which provides more possibilities for the introduction of new tool materials with higher wear resistance.
The advantage is that the tool life is quite long,Medical Parts which means shortening the machine downtime for production. In addition, the cutting edge of the blade line toughness is improved, so that the cutting edge is more sharp, cutting and more secure. The rational use of these technological advances in other areas of processing and the development of special indexable inserts and knives suitable for small parts cyclone milling have consolidated the economic advantages of manufacturing medical parts.
The continuous development of blade technology provides a greater space for improved cutting edges, making it possible to take full advantage of the benefits of threaded cyclone milling. For example, the use of coated carbide inserts results in longer and more predictable tool life and the ability to apply higher cutting speeds. This results in a higher part output, and the tolerances and surface finish are consistent. New blade materials (such as those with PVD / TiAlN coating) have a unique thin coating with excellent adhesion to the blade substrate. This material has proven to be very beneficial for the sharp cutting edges required for various types of workpiece materials such as screwed materials used for threading.
Thread safety, tool safety and tool clamping are also critical to ensure higher processing performance. The tool accuracy determines the blade positioning, the quality of the blade grinding, and the convenience and reliability of each time the blade is properly positioned. The newly developed blade clamping concept for threaded cyclone milling tools improves the positioning accuracy and machining safety of the cutting edge and makes the tool change easier and faster on the machine tool. Smooth tangential cutting is necessary to ensure that the entire process required to ensure high precision and surface finish.
At present, threaded cyclone milling tools should include specially developed precision grinding blades and semi-finished products, and should be compatible with most types and construction of the sliding knife spindle. Although high-volume production has a complete process, but to meet the needs of higher production and new parts also need new processing technology, such as screwdriver milling more advanced tool ring concept.
In an example of using a screwdriver to produce a bone screw, there are about 500,000 annual productions and small batches vary depending on the situation. After the installation of advanced indexable blade cutter, not only reduces the processing costs, but also greatly enhance the manufacturing competitiveness. This new tool means that the tool life can be extended by a factor of 8, and more parts can be machined before the cutting edge needs to be replaced (at which point the part size is about to exceed the tolerance). In addition to eliminating all machine downtime, tool maintenance is simpler and saves tool room management time.
Now, the slanting machine with coolant supply can provide new possibilities for improving small parts processing. The use of high-pressure cooling system instead of the traditional cutting zone coolant has many processing advantages. The introduction of such auxiliary cutting means does not require sophisticated equipment,Medical Parts since standard tools can be used and the use of internal cooling is a common practice. High-pressure cooling after a period of continuous research and development, only to form a high standard of today's processing concept. The biggest advantage of this approach is to improve processability and chip removal when processing chips with tight materials (such as superalloys and mild steel).
At present in the small parts processing can be applied to the new processing concept, the high-pressure coolant directly and accurately spray to the cutting area. This solution combines the precise orientation of coolant jetting and tool holder clamping for simple and safe features. This opens up a whole new perspective for more efficient processing of demanding materials, especially in slitting machines where groups of small tools are located in very narrow spaces and are difficult and time-consuming for tool change and clamping. In the machine tool with positioning and locking function and with coolant connector, the new tool clamping system can improve the processing and tool change capability at the same time.
A turning tool with a high pressure cooling (HPC) function usually has three nozzles that accurately deliver the coolant jet to the proper position on the blade. The coolant will affect the distribution of heat generated by the cutting zone, the amount of tool wear,Medical Parts the actual forming of the chips, and the degree of adhesion of the workpiece material attached to the cutting edge. The coolant injection can effectively shorten the knife-breaker contact length by a so-called "hydraulic wedge" formed between the chip and the blade rake face. It has been confirmed that this has a great impact on tool life and chip formation. Achieving good chip control in the machine tool helps ensure safe unattended production as well as tolerances and surface finish levels for machined parts, and thus increases productivity.
