Hard track features
1. Advantages of hard rails:
1. It can withstand higher loads and is suitable for a large tool and large rough treatment tools.
2. Since the contact zone of the guide rails is large, the tooltip takes place more easily and it is suitable for machine tools with high requirements for machine tools such as grinders.
2. Disadvantages of hard rails:
1. The material is uneven. Negative impact on the lifespan of the guidance rail and the precision of the machine tool.
2. The treatment is difficult, because this type of guidance rail is generally integrated into the main components of the tool machine such as the base, the column, the sand, the sliding saddle, etc., therefore during the process of treatment process , its shape and its tolerance of position, the roughness requirements and the effectiveness of time.
3. Assembly is difficult. The precision of the machine tool can only be supplemented by assemblers who are sure of global precision. and other corresponding tools to be completed.
4. The lifespan is not long. Relationship: hard rails operate in slippery friction, while linear rails operate in rolling friction. The hard rails are even worse.
5. The maintenance cost is too high. Since the caliber and mechanical treatment are done again, most can be overhauled and the wire gauge can be replaced by the corresponding metallic rail, which will not essentially affect the use of the large relevant part .
6. The machine tool has a low racing speed. In particular, many factories do not have knowledge of the corresponding maintenance of machine tools. The track is not sufficiently lubricated, it will lead to the burn or wear of the track, which will be fatal to the precision of the machine tool.
Line and rail characteristics
1. Advantages of the line and the rails
1. It is practical and simple to assemble. Since the accuracy of the tool-machine is very important, the degree determines the accuracy of the transmission mechanism. Machine-tool and rails and screws are generally existing in the form of standard parts.
2. There is a lot of space for the selection. Unlimited depending on the specific situation of the machine to the tool you have designed.
3. Quick racing speed. The precision and stability of high -speed operation considerably improve the effectiveness of the treatment and the precision of the treatment.
4. High treatment precision because as a standard product, metal rails have entered a benign control range in material and treatment methods. , this also guarantees that the treatment accuracy of the machine tool. Various wire tracks with different requirements.
5. Long service duration, because the racing mode of the wire rail is rolling. Hard rail.
6. Low maintenance cost. are precision responses and adjustments, but compared to hard tracks, it’s really practical.
7. The delivery cycle is short and the general delivery cycle of the line rail can be completed in a half-house unless you choose foreign brands, such as Rexroth and Thk. As long as the wire rail model you choose is not very biased, the delivery time of about half a-hen can be guaranteed, and the Taiwan Shangyin iron wire can even reach a delivery cycle of A week, but the same hard ways are not having such a good time to control them.
2. Disadvantages of line tracks
1. The loading capacity is relatively small. .
2. Stability is relatively lower than hard rail, such as the ability to resist vibrations, but I always want to emphasize that this weakness is compared to hard rail. Alright.
3. pay particular attention to the protection of metal wire during transport and assembly, because as a standard part, its unique structural characteristics put it in an embarrassing situation where it is more sensitive to damage, such as the thin form, which leads to wired rail. Other solvents during transport and assembly.
The above is some of the shallow understanding of hard rails and rails by a designer that has been engaged in the design of the machine tool for more than 10 years.
