Basic introduction and use of milling inserts

Release date:2016-07-27 Author: Click:

        A milling cutter is a rotary cutter with one or more cutter teeth for milling insert machining. During the work, each tooth cuts the remaining amount of the workpiece intermittently. Milling inserts are mainly used to machine planes, steps, grooves, forming surfaces and cutting workpieces on a milling machine. There are two common types of milling cutters: high speed steel and hard alloy. The latter has higher hardness and stronger cutting force than the former, which can increase the rotational speed and feed rate, improve productivity, make the knife not obvious, and process difficult-to-machine materials such as stainless steel/titanium alloy, but the cost is higher, and the cutting force is rapidly alternating. It is easy to break the knife in the case.

        Basic introduction and use of milling inserts

        

        One: milling blade use and length

        

        Milling inserts are generally used in CNC machining centers, cnc engraving machines. It can also be loaded onto a conventional milling machine to process some hard and uncomplicated heat treatment materials. Divided into standard and extended. Generally, the lengthening knife of the same diameter is more expensive than the standard length.

        

        It can be used in tool steel, alloy steel, pre-hardened die steel, other high-hardness machining, edge ball end mills, and can be widely used for profiling. The surface roughness of the processed workpiece is good. High heat resistance coating for high speed machining. 280/480 material to be cut; carbon steel, alloy steel, cast iron, copper alloy, 500/600 material to be cut: hardened steel, stainless steel, processing hardness: HRC50/55/60/65-68. The product uses high quality carbide and the latest technology, so it has good cutting performance and durability. For a variety of different materials such as steel, cast iron, copper, aluminum, etc., satisfactory cutting results can be obtained under reasonable sharpening and reasonable selection of cutting conditions.

        

        The structure of the milling insert is divided into four types. 1 integral: the body and the cutter are made in one piece. 2 integral welding tooth type: the cutter teeth are made of cemented carbide or other wear-resistant tool materials and brazed on the cutter body. 3 Inlay type: The cutter teeth are fastened to the cutter body by mechanical clamping. The replaceable teeth can be either the cutter head of the overall tool material or the cutter head of the welding tool material. The milling cutter with the cutter head mounted on the cutter body is called the internal sharpening type; the cutter head is separately sharpened on the clamp, which is called the external sharpening type. 4 indexable type (see indexable tool): This structure has been widely used in face milling cutters, end mills and three-sided milling cutters.

        

        Milling inserts are divided into two categories according to the processing of the back of the tooth. 1 Conduit milling cutter: Grinding a narrow blade on the back to form the back angle. Due to the reasonable cutting angle, its life is higher. The back of the pitch milling cutter has three forms: straight line, curve and fold line. Linear backs are often used for fine-toothed finishing cutters. Curves and creases have better teeth strength and can withstand heavy cutting loads, and are often used for coarse-tooth milling cutters. 2 shovel milling cutter: the back is processed by the shovel (or shovel) method into the back of the Archimedes spiral. After the cutter is blunt, only the front is regrind, and the original tooth shape can be kept unchanged. For the manufacture of various shaped milling inserts such as gear milling cutters.
