Introduction: What are the problems with the use of milling cutters during use? How to deal with these problems? Milling cutters are rotary tools with one or more cutting teeth for milling. They are mainly classified into cylindrical milling cutters, face milling cutters, end milling cutters, three-edge milling cutters, angle milling cutters, and saw milling cutters. And T-shaped cutters. Classifying Screening Classifier

Xiao Bian summed up the common problems and solutions for the use of milling cutters for everyone:
1. Overcutting
Solution: reduce the depth and width when cutting
2. Machine or fixture lacks accuracy
Solution: Repair the machine and fixture
3. Machine or fixture lacks rigidity
Solution: Change the machine, fixture or change cutting settings
4. Too few blades
Solution: Use a multiple blade end mill
In the daily use of milling cutters, it is also very important to maintain the equipment. If the milling cutter axis line and the workpiece edge line are coincident or close to the edge line of the workpiece, the situation will be serious.
Regular maintenance also helps slow down the passivation of the cutter. When the milling cutter is passivated, it is necessary to check the wear condition of the cutter in time. If the degree is light, use a whetstone to grind the cutting edge. If the wear is heavy, it must be sharpened to prevent excessive wear of the cutter.
The following small series lists the phenomenon of passivation of cutters for everyone to help determine if the cutters passivation.
Passivation of the milling cutter:
1. From the point of view of the chip shape, the chips become coarse and flaky, and the color of the chips is purple;
2. The workpiece surface roughness is very poor, the surface of the workpiece appears bright spots, there are trowel marks or ripples;
3. The milling process produces severe vibrations and abnormal noise;
4. There is a shiny white point on the knife edge;
5. When carbide milling cutters are used to mill steel parts, a large number of fire mists often fly out;
6. A lot of smoke is generated when milling steel parts with high-speed steel cutters.
1.High degree of automation and strong stability; The scope of application is wide.
2.There are four different types of the classifiers :high-weir single spiral,high-weir twin spiral,sunken single spiral and sunken twin spiral.
3.Frequent maintenance of the scoop is avoided and wearing of the big and small gears is reduced.
4.Using materials and processing technology with excellent properties, ensure that the wear is mild and uniform, and prolong the service life.
5.Compared with other classifiers, the energy consumption is reduced by 50%.
6.High accuracy and high precision, completely eliminate the large particles and screen residue in the products;
7.It is convenient to maintain and operate, and greatly reduces maintenance.
