Selection of advertising engraving machine screw and countertop?

1. Selection of the advertising engraving machine screw:

(1) Determine the diameter of the advertising engraving machine by the load. There is output torque in the motor performance parameters. If it is also equipped with a reducer, it should be counted in (considering efficiency). Calculate how much thrust is needed in the actual working conditions. The ball engraving machine sample (with the manufacturer) has load parameters (ie thrust). Parameters, generally marked as dynamic load and static load, see the former), select the nominal diameter of the ball screw.

(2) Determine the ball screw lead at linear speed and rotational speed. The advertising engraving machine motor knows the output speed. Consider the maximum linear speed you need. Multiply the motor engraving machine motor speed (if the speed reducer is divided by the reduction ratio) by the lead screw value is the linear speed. The value is greater than the required value.

(3) Determine the length of the ball screw of the advertising engraving machine according to actual needs (total length = working stroke + nut length + safety margin + installation length + connection length + margin). If protection is added, such as sheath, sheath is required. The expansion ratio (usually 1:8, ie the maximum elongation of the sheath divided by 8) is taken into account.

(4) Determine the accuracy of the ball screw of the advertising engraving machine according to actual needs. Generally, the machine can be selected below C7, and the number of CNC machine tools is more than C5 (corresponding to the domestic standard is generally P5~P4 and P4~P3, see the sample for details).

(5) Determine the shape of the ball screw nut of the advertising engraving machine according to the installation conditions and size structure (the nut has many structures, and the different nut structure sizes are slightly different, depending on the situation, it is recommended not to choose too special, in case something goes wrong Maintenance replacement has no door).

(6) Ask the price of the selected product manufacturer) payment terms and delivery time. This designer should not think that it is a matter of purchasing. In fact, many manufacturers (imported domestically produced) have a model on the product model that does not produce or accept small orders at all. It is printed to show that I am a big factory. , can do anything. Don't wait for you to finish the drawing. Other parts. When you start to make accessories according to this model, people will tell you that the delivery time of this model needs 3) 4 months to finish.

(7) Select to determine the installation method (end) of the advertising engraving machine. This mounting can be designed by yourself or it can be purchased ready-made with a standard mounting. If you design your own attention to the force state, the bearing is best to choose 7000 or 3000 series, because the screw is mainly subjected to axial force when working, and the radial force should be avoided as much as possible.

(8) Consider the guides and mounting capabilities. It is recommended to use the guides for the advertising engraving machine and the ball screw to select the ball linear guide. Of course, the combination of the linear axis and the linear bearing is a relatively economical choice.

(9) According to the above determined conditions, draw the arrow diagram of the advertising engraving machine ball screw (mainly the end mounting size, this should be detailed, to provide the shape size and tolerance).

2. Selection of advertising engraving machine countertops:

(1) Material size factor: Consider the size of the material you need to process, so that you can determine the size of the advertising engraving machine.

(2) The texture of the material to be processed: different materials have different requirements on the texture of the countertop. So take this into account.

(3) Whether there is much dust in the processing material: If there is a lot of dust in the processing material, then a vacuum adsorption device is needed.

What are the advantages of advertising engraving machine screw?

1. Power saving. The ball screw has a driving torque of less than 1/3 compared to the past sliding screw pair, that is, the power required to achieve the same motion result is 1/3 of that of the rolling screw pair.

2, the current precise micro feed. The ball screw pair utilizes ball movement, and the starting torque is extremely small, and there is no creep phenomenon like sliding motion.

3. High sports efficiency. There are a lot of balls between the screw shaft of the ball screw pair and the screw nut for rolling motion, which can achieve higher motion efficiency.
