Milling of metal materials is one of the most commonly used machining methods in machining. Milling is the use of milling cutter in the milling machine to remove part of the balance, access to a certain dimensional accuracy, surface shape and position accuracy, surface roughness requirements of the processing method.
It has a wide range of processing, high production efficiency, the economic processing tolerance level is generally IT9 ~ IT7, surface roughness 12.5 ~ 1.6um. Therefore, the milling process in the machine manufacturing industry has an important position.
Common milling machines:
(1) Horizontal lift milling machine
Horizontal lift milling machine has a vertical movement along the bed of the lifting platform, the table can be vertical and vertical movements with the lift, the elevator can be used for vertical and horizontal movement; machine spindle and table parallel to the table. This machine is easy to use, suitable for processing small and medium parts. Typical horizontal lift milling machine model for the X6132.
(2) Vertical lift milling machine
The main difference between the vertical lift milling machine and the horizontal lift milling machine is that the spindle of the machine is perpendicular to the table. Typical vertical lift milling machine model for the X5032.
(3) Universal tool milling machine
Universal tool milling machine has a horizontal spindle and vertical spindle, the table for vertical and vertical movement, horizontal movement by the spindle to achieve. This machine can complete a variety of milling work, widely used, especially suitable for processing a variety of fixtures, tools, tools, molds and small complex parts. Typical universal tool milling machine model X8126.
(4) Gantry milling machine
Gantry milling machine is a large machine tool, milling power installed in the gantry rails, a vertical spindle box and horizontal spindle box, for horizontal and lifting movements. The table is placed directly on the bed, heavy load, can be processed heavy parts, but only for vertical movement. Typical gantry milling machine model for the X2010.
