2. Determine the lead of the ball screw with linear speed and rotational speed. Advertising engraving machine motor determines the output speed. Consider the maximum linear speed you need. Multiply the rotational speed of advertising engraving machine motor (if there is a reducer divided by the reduction ratio) by the lead of the lead screw, which is the linear speed, which is greater than the required value.
3. Determine the length of advertising engraving machine ball screw according to actual needs (total length = working stroke+nut length+safety margin+installation length+connection length+margin. If protection is added, such as sheath, the expansion ratio of sheath (generally 1: 8, that is, the maximum elongation of sheath divided by 8) needs to be considered.
4. Determine the accuracy of advertising engraving machine ball screw according to actual needs. General machinery can be selected below C7, and CNC machine tools can be selected above C5 (domestic corresponding standards are generally P5~P4 and P4~P3, see samples for details).
5. Determine the form of advertising engraving machine ball screw nut according to the installation conditions and size structure (nuts have various structures, and the sizes of different nuts are slightly different, so it is recommended not to choose too special ones, and there is no way to repair and replace them in case of problems).
6. Ask the price, payment terms and delivery time of the selected product manufacturer. Designers should not think that this is a procurement problem. In fact, many manufacturers (both imported and domestic) do not produce or accept small orders at all. Probably printed to show that I am a big factory and can do everything. Don't wait until you have finished choosing and painting, and other parts will start to make accessories according to this model. You buy it, and people tell you that the delivery time of this model will take 3 or 4 months to die.
7. Select and confirm the installation mode of advertising engraving machine (End). This mounting piece can be designed by yourself or bought off-the-shelf, and there are standard mounting seats to choose from. Pay attention to the stress state in your own design. It is best to choose 7000 or 3000 series bearings, because the screw is mainly subjected to axial force when working, and try to avoid radial force.
8, consider the guidance and installation ability. It is suggested that advertising engraving machine and ball screw should choose ball linear guide rail, but the combination of linear shaft and linear bearing is a relatively economical choice.
9. Draw the drawing of advertising engraving machine ball screw according to the above conditions (mainly the end installation size, with details, shape, position, size and tolerance).
