The maintenance of the three-roll gate is very important. Like the automobile, it needs maintenance and maintenance. The maintenance and service of the three-roll gate directly affects the service life of the three-roll gate. Therefore, regular maintenance and maintenance of the three-roll gate must be done regularly, and it should be done as required. Many users rarely maintain or even do not maintain it at all. Only when the machine is broken, does it think of the manufacturer and only then replace the components. This is often due to small losses, usually there is no maintenance, a little bit of a problem, a long time will affect the use, so the user must be aware of the importance of maintenance of the three roller gate in use.
The three roller gates generally maintain the following points:
First, external maintenance
Most of the three-roll gates are made of domestically produced SU304 stainless steel. Once a week, the exterior is cleaned, rust spots are removed, the surface of the chassis is polished with a soft cloth and fossil powder, and anti-rust oil is applied. The rust-proof oil just applied is not to be used by hand. Rub, wait 3-5 hours natural drying can hand contact, otherwise it will destroy the surface rust effect. If it is sprayed on the exterior, wipe out the dust on the outside and expose the scratches. Use the same color paint to make up for it, or use the "Lidobe" used in the car for repair.
Second, the movement maintenance
The movement is the heart of the machine and it must be maintained. It is generally maintained once a month. Open the top cover to cut off the power supply, clean the dust, and then clean the drive section and add butter or high-consistency oil. Check whether the fasteners are loose, tighten the fasteners, check the wear of the wearing parts, position the arm and the positioning plate more than 3mm, replace the above gaps in time, normal clearance (1-1.5mm), solenoid valve The proper addition of butter or oil in the core, so that the solenoid valve in the left and right movement is to reduce the resistance, get the lubrication, not too much, should be appropriate.
Third, the circuit part of the maintenance
According to the previous use situation, to see whether there is a problem in the electronic control part, if there is no problem, check whether the power supply is exposed to be bandaged, the wires are sorted out, and if the wire is aged, replace it. Refer to the instructions of the three-roll gate and check the parameters of each part. If you have problems, you must follow it, find the source of the problem, and replace individual electronic components.
The above maintenance must have special personnel to maintain, especially the maintenance of the electronic control part, to be trained professionals, a full understanding of the principle of electronic control, in order to post operation.
Everyone knows that 3D Printing is an excellent way to produce prototypes for concept review or form-fit-function testing, but the examples listed are evidence that it`s becoming an increasingly popular method for producing [real" parts. This is especially true when volumes are low enough that casting and molding are not cost effective, or where part complexity prohibits processes like machining. Before you begin work on your next medical device or aerospace component, however, consider the following:
Technology: PFMOLD uses three different additive manufacturing processes: direct metal laser sintering (DMLS), selective laser sintering (SLS), and stereolithography (SL). By virtue of its ability to create fully dense metal parts on demand, DMLS is a tested and proven option for end-use applications, although SLS is often an excellent solution for low-volume plastic end-use components. SL has always been a prototype-centric process, although secondary coating technologies exist to add durability to SL`s resin-based parts.
3D-printed parts

Material selection: The nearly two dozen 3D-printable resins and powders available at Protolabs address many of the mechanical and electrical requirements in parts today, and most are suitable for long-term use. From cobalt chrome to glass-filled nylon, a variety of end-use parts can be manufactured in cost-effective quantities, accurately enough to compete with machining and injection molding.
Design considerations: In many cases, there`s limited differences between a prototype part design and one destined for years of service. What`s important is that product designers and engineers recognize 3D printing`s potential for such use. The ability to create organic shapes and complex lattices opens doors otherwise closed to traditional manufacturing.
Production quantities: Despite its many strengths, 3D printing is relegated to relatively smaller part quantities, limiting its use for most high-volume applications. Because of this, understanding what quantities are appropriate for end-use parts is an important step in any design project. Anything from a single replacement part for a vintage automobile to on-demand production runs of complex componentry may be practical, provided the part cannot be produced more cost-effectively via alternative manufacturing methods.
