Drilling and milling machine both have drilling and milling function, fully functional, drilling and milling machine has two main milling types.
1、 Aroud milling
Using milling cutter cutting edges on the circumference of a circle, called Zhou Xi, also known as peripheral milling, due to the cylindrical milling cutter is composed of multiple blade, so there will be tiny corrugated milling plane. At the same time, the stand or fall of the cylindricity directly affect the milling surface flatness.
2、End milling
Using end milling cutter end milling tooth, called the end milling, It is to use the cutter blade on the end to form a plane, so there are lines in the processed surface knife, the knife the roughness of the grain size is related to such factors as the speed and feed rate. In addition, drilling and milling machine spindle axis and workpiece feed direction of verticality decided the plane milling of good or bad.
Aroud milling compared with analysis of end milling
Aroud milling and end milling are separated in single plane milling, the milling steps and grooves, etc., and tend to exist at the same time. Regarding the situation of the milling of a single plane of Zhou Xi and comparing the end milling is as follows:
(1)The face milling cutter tool rod shorter, the clamping rigidity is better, more artifacts of blade at the same time, small vibration, and a long cylindrical milling cutter tool rod, diameter of axle is lesser, at the same time artifacts of cutter tooth is small, so easy to make a tool rod bending deformation, caused by vibration.
(2)Face milling cutter is easy to set for high speed milling carbide blade, high production efficiency, the milling quality is better also, and the cylindrical milling cutter with carbide insert more difficult.
(3)Face milling cutter diameter up to 1 m or so, can a milling out wide surface, and the cylindrical milling cutter in milling width larger artifacts, general milling knife, so the traces left by knife.
(4)The blade Angle of the cylindrical milling cutter can use big, the milling for difficult-to-machine materials have certain help.
All this some determines the end milling machining quality and production efficiency is higher than Zhou Xi, so commonly used while processing flat end milling.
