Replaceable head cutting tools are unique in the field of mechanical processing tools, belonging to the existing tool categories and also having relative independence.
Its birth meets the unremitting pursuit of users for the convenience of tool use and the reduction of tool costs. It is reported that the initial design inspiration is most likely to come from the indexable刀片. In the development history of cutting tools, if the welded hard alloy cutting tool can be regarded as the "first industrial revolution" in the cutting tool industry, then the advent of the indexable cutting tool can be regarded as the "second industrial revolution" in the history of cutting tools. The "disposable" design of the cutting edge brings great convenience and cost reduction, which greatly promotes the progress of the mechanical processing industry.
However, due to their own size limitations, there is one group of cutting tool products that have never benefited from the invention of indexable cutting tools, until this innovative replaceable head cutting tool came along.
The characteristics and advantages of replaceable cutter heads
-
Economical: The replaceable blade only requires the replacement of the cutting edge section, without the need to replace the entire blade, effectively reducing the cost of blade replacement and enhancing economic efficiency.
-
Flexibility: The ability to select different types and specifications of cutting edges based on various machining requirements, making the machining process more flexible and versatile.
-
Easy maintenance: The cutting edge part can be replaced separately, which facilitates maintenance and care, and extends the life of the tool.
-
Improve production efficiency: Changing only the cutting part saves time on tool changes, which in turn helps to improve production efficiency.
Typical replaceable cutter
-
Replaceable head drill bit: For example, the 870 drill bit of Cola and the crown drill of Kener. The replaceable head drill bit is suitable for drilling processing of various materials, with the characteristics of low cost and wide universality.
-
Replaceable Head Milling Cutter: The replaceable head milling cutter is suitable for processing such as flat milling, vertical milling, and side milling, and can replace different types of cutting edges according to different processing needs. Typical representatives include the Little Demon of Sweden's Sandvik and the CM316 of Sandvik's Seco.
-
Replaceable Head Counter Sink: The replaceable head counter sink is a typical finishing cutter, which is used in combination with an adjustable tool holder to machine holes with high precision and achieve better economy. Typical examples are Mapal and URMA.
-
Replaceable head tap: Can achieve similar functions to a whole tap and is cheaper.
-
Replaceable head steel product tool holder: This is a different kind of category, by designing the replaceable head tool on the steel product tool holder, to obtain the advantages of replaceable head, such as vibration-proof tool holder, vibration-proof boring tool holder, large diameter indexable cutting tool drill bit, etc.
Removable head products as substitutes for integrated products, to be successful, must overcome a major problem, that is, the stability and accuracy of the interface.
Looking at all kinds of products, the replaceable drill bits are undoubtedly the most successful and highest value product category. Let's understand the design principle of the replaceable drill bit with the example of the Colm 870 drill bit. The 870 interface part covers the side wall support surface - bearing torque, the bottom support surface - providing axial support, the triangular column pin - centering, and the screw - clamping. This ensures that the cutting head is safely wrapped in the cutting seat, and the triangular column pin achieves centering, thus achieving a high safety factor and low cutting edge跳動.
Nowadays, replaceable head drill bits are widely used in the energy, wind power, automotive and general machinery industries. Pu has been deeply cultivating the field of drilling bits for many years, and with the help of the trend of replaceable cutting tools, it timely launched its own replaceable head drill bit products and carried out a series of expansion in 2024.
The DC12.5 - DC40 hole diameter can be covered by the replaceable head diamond bit, and the length diameter ratio of the drill rod includes 1.5, 3, 5, 7, 8.5, 10, 12×DC, and the processable materials cover a variety of materials such as steel parts, cast iron, stainless steel, etc. The research and development of larger specifications of diamond bits is in progress.
