The new cutting tool concept is revolutionizing the processing of small parts in the medical industry, significantly boosting production efficiency. The development of slitting machines for machining tiny components has driven the evolution of cutting tools, enabling higher performance and better machine utilization. Key advancements include thread whirling and turning with High Pressure Cooling (HPC), both of which have elevated cutting tool capabilities to new levels.
As competition intensifies in manufacturing, the demand for high-performance metal parts—such as slender bone screws—has increased. Thread whirling, a well-established method, offers inherent stability ideal for mass production of challenging materials. With improved cutting edges, manufacturers can now use more durable materials, leading to longer tool life and reduced downtime. Enhanced edge toughness also ensures sharper, safer cuts, improving overall efficiency.
These innovations have led to the creation of specialized indexable inserts and knives designed for small-part milling, reinforcing the economic benefits of producing medical components. Continuous blade technology improvements allow cutting edges to fully leverage the advantages of thread whirling, such as using coated carbide inserts that offer extended, predictable tool life and higher cutting speeds. These inserts, often coated with PVD/TiAlN, provide excellent adhesion and are well-suited for machining various materials used in medical applications like bone screws.
Operational safety and precise tool clamping are essential for maximizing thread whirling performance. The newly developed insert clamping system enhances cutting accuracy and simplifies tool changes on the machine. Smooth tangential cutting ensures consistent precision and surface finish throughout the process.
Modern thread whirling tools now include specially developed inserts and semi-finished products compatible with most sliding toolholder spindle configurations. While mass production processes are well-established, new demands require advanced techniques, such as improved tool ring concepts.
In one example, bone screws produced at a rate of 500,000 annually benefit from advanced indexable inserts. This reduces costs and boosts competitiveness, extending tool life by up to nine times and minimizing downtime. Easier maintenance further improves efficiency.
High-pressure coolant systems are transforming small-part machining. By replacing traditional cooling methods, these systems improve chip control and material removal, especially for difficult-to-machine materials like superalloys. Coolant is precisely injected into the cutting zone, enhancing tool life and chip formation through a "hydraulic wedge" effect.
Tool change on machines equipped with HPC is quick and efficient, using a single screw and spring-loaded wedge for secure, fast clamping. This setup ensures accurate cutting edge positioning and supports safe, unattended operation. The CoroTurnQS-HP tool exemplifies this, offering high-pressure cooling and rapid tool changes.
Recent developments in cutting tools, such as the CoroMill325 thread whirling system, provide efficient, precise, and safe threading solutions. These innovations are no longer just problem-solving tools but key enablers of optimized performance across the medical industry.
S-Type Load Cells
S-type load cells, also referred to as S-beam load cells, are force sensors specially designed to accurately measure both tension and compression. The name "S-type" is derived from their distinctive S-shape. Some users prefer to call them "Z-type," referring to their structured centre beam spring element.
The S-type load cells we offer vary in capacities, ranging from a nimble 25kg up to an impressive 30 tonnes. These units utilize advanced metal foil strain gauge technology. Their notable accuracy and compact design attributes make them a top choice for applications requiring precise force measurements. With easy and versatile installation using rod ends or load buttons, S-type load cells deliver outstanding performance for tension and compression applications alike.
Our range of S-type load cells is available in both low and high-capacity options. They are primarily designed to measure tensile forces but are equally competent in measuring compressive forces.
Built from stainless steel or aluminum alloy, depending on the range size, these sensors offer measurements from as light as 200g up to a hefty 1T. Their high precision, easy installation, and reliable stability are just some of their numerous advantages. With such robust features, they are a perfect fit for applications such as dosage scales, packaging scales, hook scales, and technical control equipment. Through precise force measurement, they enhance the reliability of these devices, helping to optimize operations and product quality.
