1. Please confirm that the supply voltage level is consistent with the rated voltage of the product; whether the incoming line is correct, and check the peripheral circuit for short circuit. Whether the connected line is fastened. Otherwise, it may cause product damage!
2. Please do not touch the wiring terminal when electrified, otherwise it may cause electric shock and misoperation.
3. Please read the manual and fully confirm the safety, and then operate the machine. Operation error will damage the machine and cause accidents.
4. The external power supply must be cut off before cleaning and increasing the terminals, which may cause electric shock when energized.
5. Maintenance of the electrical equipment of the machine tool should be carried out by professional technicians, and the power switch should be cut off before repair to avoid the danger of electric shock.
Vi. When using the product, users do not change the structure and electrical control part of the product by themselves, otherwise the equipment and personal safety accidents may be caused.
The rough value of assembly and surface rent of cutting machine
The assembly of cutting machine is the last production process of machine manufacturing, and the quality of mechanical and electrical products must be guaranteed by assembly. In order to ensure that the machine or instrument can be assembled smoothly, and to achieve the predetermined assembly accuracy and functional requirements, it can be realized from two aspects of design and assembly process. When designing the dimensional accuracy and geometric accuracy of mechanical parts, the requirements of the overall assembly accuracy should be considered, and the dimensional tolerance and geometric tolerance of the relevant parts and components should be determined economically and reasonably through comprehensive analysis and calculation, namely the allocation of the assembly tolerance. In the process of mechanical precision design, the allocation problem of assembly tolerance can be solved by using the related principle of size lead and the corresponding analysis and calculation method. In the assembly process party group, DJ adopts the advanced assembly process or method in the assembly process. To ensure the assembly accuracy requirements.
When designing all parts, the selection of the cutting machine is the analogy method, this method is simple, rapid, province-saving, can not only meet the requirements of parts, but also take into account the general principle of selection. For the specific selection, please refer to the following principles.
(1) General principle: on the premise of ensuring the surface function requirements of the parts, choose a larger surface roughness parameters as far as possible.
(2) The roughness parameter value of the surface of the same part J:, r: cutter machine should be small on the hlk working surface.
(3) The value of the roughness parameter of the friction surface is smaller than that of the non-surface surface. If the friction speed on the friction surface, the greater the unit force, the roughness parameter value; the rolling friction surface is smaller than the sliding friction surface.
(4) When the gap coordination, the smaller the gap, the smaller the parameter of rent should be, the surplus. To ensure the firm and reliable connection strength. The larger the load is, the smaller the required roughness parameter value is. In general, the gap complex is smaller than the surplus fit roughness parameter value.
(5) The roughness parameter value of the mating surface should be equivalent to the dimensional accuracy requirements. When the half-fit properties are the same, the smaller the part size, the smaller the corresponding rough degree parameter value; to one accuracy level. Small size is smaller than large size roughness parameter values. The roughness parameter value of the axis hole is small (especially the accuracy of I D 8 and IT5).
(6) The value of the roughness dimension parameter of the surface of the periodic load and the inner corner of the stress market should be small.
(7) corrosion resistance, sealing requirements, the appearance of the beautiful wave surface should choose a small roughness height parameter value.
