使用 CNC 加工製造醫療零件
製造CNC加工零件, 機械加工公司必須遵守 ISO 9001 品質要求, 但就醫療零件的製造而言, 必須滿足其他類型的要求, 符合國際標準化組織標準.
據該組織稱, 參與設計的公司, 生產, 發展, 醫療零件的分銷或服務必須證明有能力提供始終滿足客戶和監管要求的醫療設備.
為了這, 使用的標準是 ISO 13485, 得到最重要監理機構的認可.

醫用鎳鈦記憶合金加工
增加 CNC 加工複雜度的另一個因素是高公差精度範圍. 材料, 加工精度, 醫療器材零件的表面光潔度要求非常高, 對處理系統的可靠性要求較高. 所以, 對工具機也提出了極高的要求, 固定裝置, 切割工具, 和 CAM 軟體.
醫療CNC加工的要求
使用數控加工的製造商, 除了遵守所有標準和認證之外, 必須採取一系列措施. 滿足醫療CNC加工需求的基本要求是:
精密加工,公差非常嚴格
4 和 5 複雜幾何形狀的軸加工
清潔度要求高, 尤其是在植入物製造方面
製造材料種類繁多, 從不銹鋼到醫用塑料
最高水平的表面光潔度
採用 CNC 加工製程的醫療植入物
毫無疑問, 醫療數控加工最重要的應用之一是身體植入物的製造和生產.
CNC 加工非常適合患者和特定植入物的製作, 因為響應時間很短,並且沒有用於創建定制植入物的工具成本,而不是大規模.
Implants are created from metals like titanium and special plastics like PEEK. These materials are strong and biocompatible.
It is essential that they are materials that do not decompose within the human body and that they do not suffer from corrosion.
In any case, there are materials that are difficult to machine since they accumulate heat and the coolant due to contamination issues is prohibited in most cases.
The most common implants created through CNC machining are hip, spine and knee implants.
The most commonly used materials for the manufacture of machined implants are titanium and cobalt-chromium alloys, stainless steels and polyether ether ketone (窺視).
Manufacture of surgical instruments through CNC machining
CNC machining can be used to create surgical instruments for medical professionals. 手術剪, 切片管, 切割機, 鉗子, 夾子, 透過這種製造過程可以製造更多的樂器.
毫無疑問, CNC 加工是適合此類儀器的製造工藝, 因為它可以提供必要的精度並滿足必要的安全要求.
醫療設備製造商使用 CNC 加工來提高精度,而且工具必須小批量製造, 有時甚至針對個別患者. 另外, 可確保完美的表面光潔度,避免缺陷.
製造手術器械最廣泛使用的材料是不銹鋼和鈦合金.
CNC 加工製造電子醫療設備零件
數控工具機可用於製造比手術器械更複雜的設備零件, which consist of one or two metal parts.
There are medical equipment that can comprise many individual parts and many of them can be created from CNC machining.
These pieces can be very small items like switches or larger pieces.
All these parts must be of the highest standard so that the machine of which they are part does not present any subsequent failure. As they are not implants or surgical tools, many more materials can be used because they do not come into direct contact with the patient.
Among the medical equipment that use CNC machined parts we can find: ultrasound equipment, magnetic resonance imaging, diagnostic equipment, monitors …

醫療微加工零件
Micro machining
Within the medical industry, it is sometimes necessary to manufacture very small parts. For these cases, CNC machining can manufacture very small parts with the necessary precision. Many times the size of these components is much less than 50 微米.
It can be used to manufacture catheters, pacemaker components, miniature screws for implants or devices, ophthalmic components among other uses.
Keep in mind that not all machining centers are suitable for creating this type of component. It requires using especially fine cutting tools and meeting all tolerances for small parts.
Workpieces are usually processed on internationally advanced machining equipment such as Swiss automatic lathes, multi-spindle machine tools and 5-axis rotary tables. These machine tools are mostly characterized by very small size and very compact structure.
The characteristics and requirements of medical device parts processing undoubtedly promote the development of processing technology and solutions. Improve the competitiveness and production efficiency of small and medium-sized enterprises in processing medical accessories.
The manufacturing process by CNC machining is of vital importance for the medical industry due to its perfect precision, versatility in materials and speed. It is useful from the manufacture of surgical tools, to hip implants and numerous medical applications.
Many of the specialized medical machine shops manufacture the parts through the CNC machining process. This is due to the requirement to manufacture these parts with very strict tolerances and with safe and compatible materials. 另外, they are capable of manufacturing the parts to meet all international requirements and standards.
Parts such as body implants, which require tight tolerances and a perfect level of precision, use CNC machining due to the ideal characteristics that this type of manufacturing presents.
Any workshop with machining machines can manufacture medical parts meeting the established requirements.
