The superiority of helical gears over straight gears lies more in their smooth operation and the accompanying noise reduction effect. In fact, it is a misunderstanding that the speed of the engraving machine is not much related to the rack, but to the drive. To introduce the difference between the rack drive carving machine using straight teeth and oblique teeth.

　　From the principle of analysis, oblique teeth is a spiral angle β, of course, this is a professional statement, we use the ordinary saying that the tooth is crooked, and straight teeth is straight, this is very understandable, then because the oblique teeth have a spiral angle, so the bite in the force when the force area is larger, naturally, the ability to withstand some relatively stronger than the straight teeth, of course, the difference between the two will not be Very big, specific data customers can ask the engraving machine manufacturer's technician, this more detailed data is generally only the technician will be more understanding.

　　The superiority of the helical teeth over the straight teeth lies more in its smoothness of operation and the accompanying noise reduction effect. What's the use of smoothness? That is really useful, many carving machine, especially stone carving machine carving stone is required for a long time (marble, bluestone and other stone, hard material, the starting knife carving depth is naturally not as deep as other light materials, carving by the friction is naturally greater), carving machine for a long time without stopping operation requires a more stable working condition, if the work schedule If the deadline is tight, the carving machine needs to run for a very long time, this time the advantages of the oblique tooth carving machine will show up. Of course, in general, unless your processing plant business is really very good (if very good, then in fact, you can consider buying new machines instead of squeezing the original machines, after all, so long operation engraving machine life is easily affected), otherwise the difference between straight teeth and oblique teeth is actually not much.
