Milling machines — a universal tool with a multi-blade cutting tool — a milling cutter; The main movement is the rotation of the mill. The spindle carrying the cutter is vertical, but in many cases it can be installed at an angle to the workpiece. The movement of the table, carried out manually or by means of a mechanical drive, is precisely controlled by graduated limbs on the lead screws and precision scale with optical magnification.
The milling mandrel (shaft carrying the cutter) is horizontal. The table on which the workpiece is fixed with the necessary equipment can be either «simple», i.e. With the displacement on three axes, or universal, i.e. Allowing corner turns.
And CNC milling machines provide for automatic control of the movement of the table and the speed of the spindle. In some cases, the spindle itself is mounted on a slide allowing it to be independently moved axially or vertically. CNC milling machine of this type allows the processing of three-dimensional surfaces, for example, blades of propellers and turbine blades s http://blueandgreytoday.com/product-category/milling-machines/ erially and with high accuracy.
Copy-and-milling machines process complex curved surfaces, for example punches and dies for punching sheet metal, molds for injection molding and extrusion. The indicator probe passes through the profile profile of the copier, and the working cutter passes this profile of the workpiece.
Classification of milling machines
Depending on the type of processing, the milling machines are divided into nine groups. In turn, each group is divided into nine subgroups, representing milling machines by their types.
The most common types are horizontal, universal and vertical milling machines.
Horizontal cantilever-milling machines have a horizontally spindle that does not change its position. The table can be moved perpendicular to the axis of the spindle in the horizontal and vertical directions and along the axis parallel to it.
Universal cantilever — milling machines
Universal cantilever-milling machines differ from horizontal ones in that they have a table that can be rotated to the required angle.
