One, the main function of milling machine
The milling machine is a machine tool for milling the workpiece with a milling cutter. In addition to milling plane, groove, gear, thread and spline shaft, the milling machine can also process more complex profile, higher efficiency than the planer, which has been widely used in mechanical manufacturing and repair departments.
Two, Classification of milling machines
1. Knee-type milling machine
Lifting table milling machine is mainly divided into vertical milling machine and bedroom milling machine, they are mainly divided into:
1) different shaft positions, horizontal spindle arrangement and vertical spindle arrangement.
2) in addition to the different layout of the spindle, their processing range is also different. Horizontal multi-purpose disc milling cutter can be used for auxiliary support with relatively better stiffness. Vertical milling cutters are more flexible and applicable to a wide range. Can use end mill cutter, machine clip cutter disc, bit, etc. Milling keyway, milling plane, boring, etc. Horizontal milling machine can also be used above a variety of cutting tools, but is not as convenient as vertical milling, mainly can be used to strengthen the tool (mainly three-sided edge milling cutter, slice milling cutter, etc.) strength.
2. Vertical milling machine
Vertical milling machine is a kind of universal metal cutting machine tool. Its spindle taper hole can be directly or through the accessories installed various cylindrical milling cutter, shaping milling cutter, end face milling cutter, Angle milling cutter, etc.
Vertical milling machine milling head can be suitable in vertical plane, reverse adjust plus or minus 45 °; Motor feed in X, Y and Z direction; Its main shaft USES energy saving brake, brake torque is large, stop quickly and reliably.
The structure of vertical milling machine: the structure of vertical milling machine is mainly composed of working table, spindle, lifting table, electronic ruler, milling head, base and switch.
In addition, vertical milling machine has two important components: the flat nose pliers and milling cutter.
Flat nose pliers: it is also called machine vice, used to clip rectangular and cylindrical type of small and medium workpieces, the use of a wide range. Some of the rotary dial is called the rotary tongs, which can be used to pull the Angle. Small and regular workpieces are often installed this way.
Milling cutters: multi-tooth cutters, usually produced by specialized factories due to their complex structure, have many types, and the most widely used are face milling cutters and end milling cutters.
Milling methods: milling methods are mainly divided into forward milling and reverse milling.
When the rotation direction of the cutter is opposite to the feed direction of the workpiece, it is called reverse milling. The same thing is called down milling.
