Machine manufacturing is an art and every artist can choose different ways to make their difference.Even if the manufactured machines do the same job, they may differ in appearance and dimensions.

LM rails are produced in standard length and sized according to need.Standard length LM rails are shorter than the length of the machine in machines with a long travel distance. In this case, LM rails need to be jointed end to end.

Cutting the LM rails to the required lengths and grinding the ends is a very sensitive operation.LM rails are very expensive products so should not be wasted.The part to be cut for usage must be calculated and if the part will be jointed with other, 1-2mm left allotted for the grinding operation.

Helical Rack Mounting Procedure

rack mounting schema

Rack and pinion drive systems are one of the most common methods used to move machine axes.They are especially preferred in machines with long stroke distances.If you are going to use rack and pinion in your machine and you need precision, you should definitely choose helical rack and pinion.

However, when making this choice, you should first pay attention to the cost of rack and pinion.Because the cost of helical rack and pinion is more than straight type.Helical ones are expensive because they are more difficult to manufacture.

However, when it comes to precision, helical rack and pinion are more advantageous in terms of both accuracy and transmissible force since they have more contact surfaces.

Of course, good assembly is as important as a good product.For this reason, we need to know some technical details and values about rack and pinion assembly.

Before starting the assembly, we need to know the allowed deviation values. Continue reading “Helical Rack Mounting Procedure”
