Introduction of end mills and the use of end mills

Today Echaintool Precision Co., Ltd. will introduce you the introduction and use of end mills.
Our End Mill Cutter products are recognized by our customers for their excellent quality!
End mills are the most used milling cutters on CNC machine tools. There are cutters on the cylindrical surface and end face of the end mills, which can be cut at the same time or individually. Mainly used for face milling, groove milling, step face milling and copy milling.
face milling
End mills can be used for face milling. However, because its main declination angle is 90°, in addition to the main cutting force, the force on the tool is mainly radial force, which is easy to cause deflection and deformation of the tool bar, and also easy to cause vibration, which affects the processing efficiency. Therefore, in addition to similar thin bottom workpieces Except for special reasons such as the need for small axial forces or the occasional reduction in tool inventory for face milling, end mills are not recommended for machining flat surfaces without steps.
side wall milling
Most workpieces suitable for machining with end mills have one or more sidewall faces perpendicular to the bottom surface (this face is parallel to the milling machine spindle), which brings about a problem that does not exist in face milling: sidewall shape and accuracy issues .
