What are the types and uses of automatic transfer machines? The type of automatic transfer machine can be divided into sharp tooth milling cutter and shovel tooth milling cutter according to the tooth structure. According to the relative position of the tooth and the axis of the milling cutter, it can be divided into cylindrical milling cutter, Angle milling cutter, face milling cutter, forming milling cutter, etc. According to the shape of the cutter teeth can be divided into straight teeth milling cutter, spiral teeth milling cutter, angular teeth milling cutter curve teeth milling cutter. According to the tool structure, it can be divided into integral milling cutter, combined milling cutter, group or complete set of milling cutter, insert tooth milling cutter, machine clamp welding milling cutter, indexable milling cutter, etc. But it is usually divided into the form of cutting tool tooth back processing.

Sharp-toothed milling cutter can be divided into the following types:

(1) Face milling cutter

There are integral face milling cutter, insert teeth face milling cutter, clamp can be transposed face milling cutter, etc., used for rough, semi-fine, fine machining of various planes, step surface, etc.

(2) vertical milling cutter

Used for milling step surfaces, sides, grooves, holes of various shapes on the workpiece and internal and external curve surfaces. If the end mill is easy to distinguish, it can be divided into two categories: left and right. Now a lot of people have no idea about left and right rotation.

Right hand milling cutter

First of all, determine tool is left-handed or right-handed can according to the following method. Facing the vertical milling cutter, if the blade groove is rising from the bottom left to the top right, this is right-handed; If the blade groove rises from the bottom right to the top left, this is left-handed. The right hand rule can also be used for right hand rotation, with the four bent fingers being turned in the direction of rotation and the thumb fingers prying up being turned in the direction of rotation. The spiral groove plays the role of chip holding and is also the part of the front Angle and front of the milling cutter.

Left-handed cutter

Left-handed milling cutter, in general, is a tool selected under the needs of high-precision machining, left-handed milling cutter is generally used in mobile phone key processing, film switch panel, LCD panel, acrylic lens and other finishing. However, there are some high requirements, especially some mobile phone keys or the production and processing of electrical panels, high precision finish requirements are also high, it is necessary to choose the bottom cut, left turn, so as to avoid the phenomenon of white knife edge, workpiece cutting edge.

(3) Keyway milling cutter is used for milling keyway and so on.

(4) Slot milling cutter and saw blade milling cutter are used for milling various slots, sides, step surfaces and sawing.

(5) Special groove milling cutter is used for milling various special groove shape, visible groove milling cutter, half moon keyway milling cutter, dovetail groove milling cutter, etc.

(6) Angle milling cutter is used for straight grooves and spiral grooves of milling tools.

(7) The mold milling cutter is used for milling the convex and concave forming surfaces of various molds.

(8) Group milling cutter Several milling cutters are combined into a group of milling cutters for milling complex forming surfaces, surfaces of different parts of large parts and wide planes.

Shovel teeth milling cutter: Some require regrinding the front still maintain the original truncated shape of the mill, their back with the form of shovel teeth, including disk slot milling cutter, convex semicircle, concave semicircle, double Angle milling cutter, form milling cutter, etc.

In addition to the above mentioned situation, in the industry there are two points of up-milling and up-milling, which are generated in two ways relative to the feed direction of the workpiece and the rotation direction of the milling machine: The first is the forward milling, the rotation direction of the milling cutter and the feed direction of the cutting are the same, and the milling cutter bites the workpiece and cuts the final chips at the beginning of the cutting; The second is inverse milling, the direction of rotation of the milling cutter and the feed direction of the cutting are opposite, the milling cutter must slip a section on the workpiece before starting to cut, starting with zero cutting thickness, and reaching the maximum cutting thickness at the end of the cutting.

Actually both general CNC lathes and other CNC milling machine, for each blade, when to exit cutting cutting edge way off the workpiece is important. The remaining material may reduce the blade clearance somewhat. When the chip is removed from the workpiece, an instantaneous tensile force is generated along the front edge of the blade and a burr is often generated on the workpiece. This tensile force endangers the safety of the chip blade in dangerous situations.
