What errors may occur during CNC machining and CNC machining​?

 CNC machining and numerical control machining are a method to control the movement of machine tools and the production process of machining through computer digitization and information digitization. It is an intelligent numerical control device developed as an economical, high-speed, reliable, multi-functional, intelligent, and open structure. CNC machining is also an important indicator that can measure the continuous level and comprehensive ability of a safety technology, as well as the degree of modernization of related science and technology capabilities, especially in aviation, biology, medical and other high-tech cultural industries, and it is also a powerful indicator. reflect. So, what errors may occur during CNC machining and CNC machining? Let us understand together:   The use of approximate machining motion or approximate tool contours causes errors in the CNC principle of machining. The reason why it is called machining principle error is because of the error in machining

What are the advantages of CNC machining of radiator parts?

For friends who have been in contact with the radiator component industry, they often see or hear "CNC machining", but too much exposure does not necessarily mean that many people understand. In fact, many questions are still about CNC machining. What are the advantages? Let's take a closer look. CNC machining is an index-controlled machine tool machining, which is a method of using digital information to control the machining process. Traditional mechanical processing is done manually by machine tools. During processing, the mechanical cutter is shaken to cut metal, and the accuracy is measured with calipers and other tools. However, traditional artificial intelligence processing is far from being able to meet the needs of production development. Therefore, the emergence of CNC machining provides the possibility for the standardization, precision and efficiency of mechanical product processing. The CNC machining process in the radiator component industry also shines. The

China Hardware’s FAQ on the Spiral Groove in CNC Milling

keywords:CNC milling,CNC milling processing

1, what is cylindrical spiral?

A: When a moving point moves at an equal velocity along a straight bus on the cylinder, which in turn rotates at an equal angular velocity around the axis of the cylinder, the trajectory of the moving point on the cylinder is called a cylindrical helix.

 

2, in the CNC milling machine milling spiral groove, the workpiece needs to have what movement? What’s the relationship between them?
Answer: in the CNC milling machine CNC milling spiral groove, must make the workpiece for constant rotation, at the same time for uniform motion in a straight line.
The relationship between them is that when the workpiece is rotated at a constant speed, the worktable must drive the workpiece while moving one lead at a constant speed in a straight line. If it is CNC milling multi-head spiral groove, the dividing head should be divided according to the number of spiral groove head.

 

3, in the universal horizontal CNC milling machine with disc CNC milling cutter CNC milling spiral groove, why to turn the table to an Angle? How to determine the size and direction of the rotation Angle of the worktable?

Answer: in universal horizontal CNC milling machine with disc CNC milling cutter CNC milling spiral groove, in order to make the direction of spiral groove and tool rotation plane consistent, must be universal CNC milling machine longitudinal table in the horizontal plane turn an Angle.

4. Where should the driving wheel and driven wheel be hung when CNC milling the spiral groove? How should intermediate rounds be determined?

Answer: when CNC milling the spiral groove, the hanging wheel is driven by the rotary movement of the longitudinal feed screw of the table. Therefore, one of the driving wheels of the hanging wheel should be hung on the longitudinal feed screw of the table, and a driven wheel should be hung on the side shaft of the indexing head. Other driving wheels, driven wheels and intermediate wheels should be correctly mounted through the pulley rack according to the corresponding relationship.

CNC Milling right spiral groove, the selection of the middle wheel should make the rotation direction of the workpiece and the table right-handed screw rotation direction consistent; CNC Milling left spiral groove, the selection of the middle wheel should make the workpiece rotation direction and table right-handed screw rotation direction opposite.

5, when CNC milling rectangular spiral groove, why can only use end CNC milling cutter and not three side CNC milling cutter? Does the CNC milling table need to turn a spiral Angle in the horizontal plane?
Answer: because spiral groove is curved surface, and the two sides of rotating three edge CNC milling cutter is plane, so with three edge CNC milling cutter CNC milling rectangular spiral groove, CNC milling will occur interference, so that CNC milling out of the groove change shape. When CNC milling with end mills, the above phenomenon will not occur. Therefore, rectangular spiral groove CNC milling to use end mills, not three edge CNC milling cutter.
With the end CNC milling cutter CNC milling spiral groove, the table in the horizontal plane does not need to turn a spiral Angle.

6. What should be paid attention to when CNC milling spiral groove?
Answer: the following points should be paid attention to when CNC milling spiral groove:
(1) The positioning pin of the CNC milling time degree handle should be inserted into the hole plate, and the locking handle of the spindle of the degree head and the fastening screw of the index plate should be loosened at this time.
(2) When CNC milling multi-head spiral groove, the table should drop a little distance when cutting back, otherwise the CNC milling cutter will scratch the machined surface.
(3) The positioning key of the dividing head should be installed in the middle of the CNC milling machine table t-shaped slot, so that the tool on the center, and then rotate the Angle of the table, the center will not change.
(4) In order to make the shape of the spiral groove CNC milling out correct, must be the correct choice of CNC milling cutter.
(5) In the process of CNC milling, measures should be taken to prevent the workpiece from loosening.
