What is the difference between milling cutters and drill bits?

A twist drill is an instrument that cuts a circular hole of a workpiece by rotating relative to a fixed axis. It is so named because its cheap flute is spiral and shaped like a twist.

The main cutting edge of the end mill is a cylindrical surface, and the cutting edge on the end face is a minor cutting edge. At work, an end mill without a center edge cannot go anywhere the axial direction of the milling cutter. According to the national standard: the end mill has a diameter of 2-50mm and can be divided into coarse and fine teeth. Diameters 2-20 are straight shank ranges and diameters 14-50 are tapered shank ranges.

How to adjust the height of the CNC lathe tailstock?

Height adjustment step:
1. Because the structure of the tailstock of the lathe is similar, if the height adjustment is necessary, the gasket has to be added.tailstock height adjustment

2, the left and right skew adjustment is simple, you can adjust the screw left and right.

3. The height adjustment method of the tailstock is to draw a cylinder with the same diameter as the tailstock sleeve on the machine tool, then suck the table of the magnetic watch on the middle carriage, and then measure the height of the workpiece and the tailstock sleeve. Can.

4. Align the dial indicator with the horizontal center of the workpiece and move the heavy carriage to measure the workpiece and the tailstock sleeve to adjust. Finally tighten the left and right screws. If the machine guide rail is used for a long time, it will wear out. If you adjust it, it may be unsuitable for all positions. If the length of the workpiece is long, you need to fine-tune it after commissioning. It is used by a scrap as long as the workpiece you want to machine, and then look at the outer circle. Consider whether there is a taper at both ends, and adjust it slightly according to the actual situation.

5. The selected gasket is not suitable. The thickness has to be adjusted. It can be fitted by grinding the thickness of the gasket or adjusting the tightening strength of the screw.

How to judge the laser head burned?
1. When the machine is working, the light was significantly weakened.
2. When the machine is working, the light is scattered and weakened, and unable to focus.
3. It can’t burn out the object when the burning time, carving material and focal length are right.

Difference linear guide and a linear slide

What is the difference between a linear guide and a linear slide?

What is the difference between a linear guide and a linear slide? Many people think that linear guides are the same as straight slides. If you think so, it is not correct. Let’s tell you about the difference between them!

Linear Guides

Both linear guides and linear slides are a component inside the machine that withstands a certain load and achieves high-precision motion under high load conditions. However, linear guides and linear slides are not the same before, and there are still different places.

Linear guides can also be called line rails and linear slides. Linear slides are a type of linear guide. Linear guides can be divided into sliding guides and rolling guides. The sliding guide rail is a direct contact between the guide rail and the slider, and the price is low, the precision is low, and the friction coefficient is large. The rolling guide is equipped with rolling elements (rollers or balls) between the guide rail and the sliding block. The rolling guide has a complicated structure, a relatively high price, a small friction coefficient and high precision.

Applied to various industries, the most important is the machinery and automation industry. The main function is to make repeated linear motions in a given direction, which can be divided into several according to the nature of friction.

What is the difference between a ball screw and a trapezoidal screw, a linear guide?

Ball screws, trapezoidal screws, and linear guides are generic conventional accessories. The names seem to be similar, but in fact they are completely different between the three, with different working principles, different production requirements, and different occasions of use. Taishang Precision Machinery Xiaobian will introduce the difference between a ball screw and trapezoidal screw and linear guide.

1. The difference between a ball screw and a trapezoidal screw. The difference between a ball screw and a trapezoidal screw is mainly the way the load is carried between the moving surfaces. The ball screw uses recirculating balls to minimize friction and increase efficiency, while the trapezoidal screw utilizes a low coefficient of friction between the sliding surfaces. Therefore, the trapezoidal screw does not reach the efficiency of the ball screw, and the efficiency is equal to about 90% of the ball screw. The fatigue life equation is very reliable within its scope of application. In summary, ball screw and trapezoidal screw have fundamental differences in their application fields because of their differences in their ability to provide for performance and life.

2. The difference between linear guides and ball screws. Ball screw is mainly used for some large-scale machine tools, engraving machines, etc. It is very convenient to convert the rotating motion into linear motion, which is very convenient to use. Thus reducing the wear and tear of the whole equipment in the rotation; the linear guide is very used. Wide range but many types, square four-row high-bead guides are used for some large-scale machine tools, such as surface grinders, slicers, wire cutting, etc.; also because of different working conditions, the linear guides are also different, most suitable for precision measuring instruments Semiconductor manufacturing and inspection equipment, non-standard automated machinery and other precision linear motion applications are important, and it is also important to choose the right guide rail for different equipment.

The “ball screw” that we often hear is actually a ball screw, but the habit is changed, and the name is different. The above is about the difference between the ball screw and the trapezoidal screw, linear guide, in fact, it is not difficult to distinguish the three, look at the introduction of the small series can know how to distinguish, I hope to help everyone.
