What does chamfering do, what is the difference between chamfering and filling?

General chamfering. The function is to remove the burr and make it beautiful. However, for the chamfer specifically pointed out in the drawings, it is generally the requirement of the installation process, such as the installation guide of the bearing, and some arc chamfers (or arc transitions) can also reduce the stress concentration.

The effect of strengthening the strength of shaft parts! In addition, it can also make assembly easy, which is generally carried out before the end of processing. On agricultural machinery parts, especially the end faces of round fittings and round holes are often processed into chamfers of about 45°.

These chamfers have a variety of functions, in the maintenance operation must be carefully checked, and make full use of it, otherwise it will bring many difficulties to the maintenance of agricultural machinery, and even cause unexpected failures. For example, before the molding process of small parts such as bolts, chamfering is also carried out in order to facilitate the material to enter the molding mold.

What does the bearing chamfer do.

1. The bearing steel must have chamfering before rough processing before heat treatment, so that it plays a very important role in the heat treatment of the material, the release of stress, the redistribution of the internal structure, the lack of cracks, and the reduction of deformation. Chamfering can solve the problem of stress concentration.

2. Chamfer and deburr, so that the product is not sharp and will not cut the user.

3. It plays the role of guiding and positioning during installation.

Generally, the outer chamfer of the outer ring and the inner chamfer of the inner ring of the bearing are rounded, in addition to effectively avoiding contact stress, the most important thing is to facilitate installation. Rounded corners allow for a good transitional loading. For more bearing knowledge, welcome to Mobei.com to understand, especially in the bearing process, the matching shaft and the positioning surface of the shaft hole, that is, the shaft shoulder and the bearing seat abutment part, the chamfer size of this part directly affects whether the bearing can be correctly installed in place.

We can see that the chamfer angle of the bearing between the axle box and the shaft is larger than that of the bearing box and the shaft shoulder, and the chamfer of the bearing must be larger than this arc to ensure that the bearing fits to the axial positioning surface. When the chamfer angle of the bearing is less than the chamfer angle of the bearing box and the shoulder chamfer, it cannot be assembled in place, which is easy to cause a series of problems such as stress concentration at the chamfer of the bearing, tilting of assembly, and inability to match other matching parts. Therefore, the fit of the chamfer must be fully considered in the assembly process of the bearing.

The difference between chamfer and fillet in CAD is that the object is different, the creation is different, and the trim is different.

First, the object is different.

1. Chamfer: The selected object of the chamfer can be either a straight line or a ray, or a construction line.

2. Fillet: The selected object of the fillet must be a straight line or a ray, not a construction line, because the construction line has no endpoint and can be used as the second object of the fillet.

Second, create different.

1. Chamfering limbs: Chamfers can not only create two-dimensional linear shapes, but also create three-dimensional solids.

2. Fillet corners: Fillet can not only be created for two objects on the same layer, but also on two objects in the current layer.

Third, the pruning is different.

1. Chamfer: When two lines are parallel, you can use the fillet to trim and extend.

2. Fillet corners: When two lines intersect or are not connected, rounded corners can be used to trim and extend.

Chamfering is a term used in mechanical engineering. For example, if you drill a hole in a piece of wood, the hole wall and the board surface will be at a 90-degree right angle. The chamfer is to make a small plane of 45 degrees on the 90-degree edge, so that the plane and the inner wall, or between the board surface, are 45 degrees.

The advantage of this is that it is more convenient to insert something into the hole without getting stuck. Such as 8x30 degrees: refers to the chamfer has been the side length is 8mm, the angle is 30 degrees to form a right triangle, commonly used in the chamfer when drawing, know that the corner side is 8 and know the angle of 30 degrees can draw the other two sides of the length and the other two sides of the angle!

Undeclared chamfer In flanges, all undeclared chamfers are mostly and 1 45°The chamfer mentioned above is a noun. In addition, in the production process of polycrystalline silicon wafers in the photovoltaic industry, there is a process called chamfering polishing, where chamfering is a verb, which means the process of treating the edges of silicon ingots to remove the edges and corners.

The chamfer is mainly in the machining of the shaft and hole along the 30 ° 45 ° 60 ° and other angles of the car or with a drilling machine and other ways to make a certain length of the slope, mainly to facilitate the installation of commonly used annotation methods (for example, C1 chamfer angle of 45 ° length of 1mm) in AutoCAD chamfer in AutoCAD to do chamfering [1] point chamfering, and then enter the angle according to the prompts, generally 30 45 60 (including °), and then enter the length, and then select the first and second edges. Depending on the order of the selected edges, there will be a difference in the chamfer at 30 to 60 degrees. If you can't see the picture on the left, please click on the original picture to browse.

Overview of chamfering in this paragraph In order to remove the burrs caused by machining on the part, and also to facilitate the assembly of the part, the chamfer is generally made at the end of the part [2].The chamfer is mostly 45°, but it can also be made into 30° or 60° [3].This paragraph chamfer annotation 45 degree chamfer annotation National standard "GB T Mechanical Drawing Dimension Note Method" in its section states:

The chamfer of 45° can be marked in the form of Figure 31, and the 45-degree chamfer is marked as shown in the figure below. Non-45 degree chamfer annotation The national standard "GB T Mechanical Drawing Dimension Note Method" stipulates in its section: "Non-45 degree chamfer should be marked in the form of Figure 32.

This is shown in the figure below. Non-45° chamfer note.

1. Chamfering. It refers to the processing of cutting the edges and corners of the workpiece into a certain inclined plane. The chamfer is to remove the burrs caused by machining on the part, and also to facilitate the assembly of the part, the chamfer is generally made at the end of the part.

2. In the building decoration project, the wall is pasted with ceramic tiles for construction, and the sun corner.

It is necessary to do the angle touching, such as: the wall corner, the pillar corner, the door opening, the window hole and so on, all of which must be touched. Years old.

The tip chamfer radius is the radius of the arc that the tip has.

Chamfering of the tip of a knife, commonly known as a blade angle, is usually an acute angle. Now the acute angle has been changed to a rounded corner for safety, and the radius r is the radius of this rounded corner.

1. Knife handle: refers to the part of the knife that is used to hold.

2. Knife grid (blocking hand): refers to the part of the knife that is used to isolate the handle and the blade.

3. Knife blade: refers to the part of the knife used to complete the functions of cutting, cutting, and stabbing.

4. Blood groove: refers to the special groove on the knife body.

5. Knife tip angle: refers to the angle formed by the point 10 mm away from the apex of the knife tip on the front back of the knife sock (or the other side of the knife edge) and the apex of the knife tip.

6. Knife edge (cutting edge): refers to the side of the knife body used to cut, cut and chop, and the thickness of the cutting edge is generally less than millimeters.

7. Chamfer of the tip of the knife: refers to the arc of the tip of the knife.

Chamfering is a term used in mechanical engineering, such as drilling a hole in a piece of wood, and the hole wall and plate surface are at a 90-degree right angle.

The chamfer is to make a small plane of 45 degrees on the 90-degree edge, so that the plane and the inner wall, or between the board surface are 45 degrees, the advantage of this is that it will not be stuck when inserting things into the hole, which is more convenient.

Introduction to chamfering: In order to remove the burrs caused by machining on the parts, and also to facilitate the assembly of parts, chamfering is generally made at the end of the part.

In addition, in the production process of polycrystalline silicon wafers in the photovoltaic industry, there is a process called chamfering polishing, where chamfering is a verb, which means the process of treating the edges of silicon ingots to remove the edges and corners. The chamfer is mainly used in the mechanical punching machining of the shaft and hole along the angle of 30 °, 45 ° , 60 ° and other angles to make a slope of a certain length or with a drilling machine, mainly to facilitate the installation of commonly used marking methods (for example, C1 chamfer angle is 45 °, long scatter imitation key is 1mm).

In machinery, the functions of inverted angles are as follows: remove sharp edges (for the sake of safety) and collapse the tomb guide (conducive to assembly).

There are several functions of rounded corners: Process fillet (where the size of the casting has changed drastically, there must be a rounded transition) to prevent the gravitational concentration of the workpiece.
