Plane milling is the most basic processing content in milling, in actual production is very widely used, for example: automotive cover moulds, engine cases and other convex surface, joint surface processing, today Nuno is also to talk to you about plane milling, but we do not talk about the complex formula, we will talk about: what are the characteristics of plane milling? What should I pay attention to in plane milling with a CNC milling machine?
What are the characteristics of plane milling?
Flat milling is generally two milling methods, respectively, circumferential milling, end milling, the 2 milling methods of the most commonly used milling method is end milling, today we will talk about the characteristics of end milling, NuoNuo collated, are in the following.
(1) In face milling, the axis must be perpendicular to the surface of the workpiece being machined. The spindle axis of the milling machine will directly affect the flatness of the machined workpiece.
(2) The face milling cutter shank during end milling has good clamping performance, and the vibration amplitude is not too large and relatively stable.
(3) When face milling, the main cutting edge of the cutter tooth and the secondary cutting edge work simultaneously, so that the surface quality of the machined workpiece is better. The main cutting edge is responsible for cutting, while the secondary cutting edge plays the role of polishing.
(4) End milling enables the use of alloy inserts of good quality and accuracy to improve efficiency and quality.
CNC milling machine in the plane milling what to pay attention to?
1, the radial circle runout of the cylindrical milling cutter.
CNC milling machine milling cutter radial runout will cause uneven cutting depth, and machining surface ripples, directly leading to an increase in surface roughness. Therefore, it is necessary to control the radial circle runout of the control milling machine milling cutter. General CNC milling machine milling cutter radial circular runout shall not exceed 0.03mm, it can be checked with a percentage table.
2, prevention of CNC milling machine milling cutter milling plane appear deep gnawing groove.
CNC milling machine milling cutter milling plane in the emergence of deep gnawing mechanism, will seriously affect the quality of the machined surface.
