A machine for milling workpieces with a milling cutter. In addition to milling plane, groove, gear teeth, thread and spline shaft, milling machine can also process more complex profile, A machine for milling workpieces with a milling cutter. In addition to milling plane, groove, gear teeth, thread and spline shaft, milling machine can also process more complex profile.
Brief history
Type
- Manufacturers differentiate the many types of milling machines based on their layout form and scope of application. Lifting table milling machines include universal, horizontal, and vertical types. They are primarily used for processing small and medium-sized parts and are the most widely used.
- Gantry milling machine: Manufacturers use machines like gantry milling machines, boring gantry mills, and double column milling machines. These machines are designed for processing large parts.
- Single-column milling machine and single-arm milling machine: The horizontal milling head of the former moves along the column guide rail. The table feeds longitudinally. The end milling head of the latter moves horizontally along the cantilever guide. Meanwhile, the cantilever adjusts in height along the column guide. Both are employed to machine large parts.
- Worktable non-lifting milling machine: There are two kinds of work tables: rectangular and round. This type of milling machine is a medium size, positioned between the lifting table milling machine and the gantry milling machine.
- The milling head lifts on the column to complete its vertical movement.Instrument milling machine: a small lifting table milling machine, used for processing instruments and other small parts.
- Tool milling machine: used for mold and tool manufacturing, equipped with a variety of accessories such as end milling head, universal Angle table and plug, but also drilling, boring and insert machining.
- Other milling machines: such as keyway milling machine, CAM milling machine, crankshaft milling machine, rolling roller journal milling machine and square ingot milling machine, etc., are special milling machines manufactured for processing the corresponding workpiece. According to the control mode, manufacturers divide milling machines into copy milling machines, program-controlled milling machines, and digital control milling machines.
Milling cutter
A rotary tool with one or more teeth for milling. When working, each cutter tooth successively intermittently cuts off the workpiece’s margin.
Milling cutters are primarily used by machinists to machine planes, steps, grooves, forming surfaces, and cutting workpieces on milling machines.
- Cylindrical milling cutter.
- Face milling cutter.
- End milling cutter.
- Three-edge milling cutter.
- Angle milling cutter.
Manufacturers classify the structure of milling cutters into four types.
- Integral: Manufacturers design the cutter body and the cutter teeth as a single unit.
- Integral welding gear type: the knife teeth are made of cemented carbide or other wear-resistant tool materials and brazed on the knife body.
- Insert type: the cutter teeth are fastened on the cutter body by mechanical clamping method. The replaceable tool teeth can be a tool head of the overall tool material or a tool head of the welding tool material. The milling cutter with the cutter head mounted on the cutter body is called the internal grinding type; The tool head grinding separately on the fixture is called external grinding type.
- Indexable: This structure has been widely used in face milling cutters, end milling cutters and three-edge milling cutters.
