With the development of large boring and milling machines and gantry machines, the demand for racks is also increasing. The rack has the advantages of high precision and high speed.

The main characteristics of the rack are: high strength, high wear resistance, and can adapt to high precision linear movement. The rack manufacturer adjusts the material to improve the strength of the rack and high wear resistance, and can change the direction of linear movement at different angles. The rack has a small modulus, is easy to use when reciprocating, and is easy to install. Due to the large contact ratio of the helical rack, it is effective in reducing noise and vibration. It has a wide range of lengths, low cost, affordable price and wide application.

In addition, it should be noted that the standard pitch line of the rack is realized by measuring the tooth thickness using the measuring roller with the bottom surface of the rack as a reference surface. If the bottom surface of the rack is processed, the rack may be The accuracy is reduced. At the beginning of operation, it is necessary to pay attention to whether the precision rack is fixed on the base surface stably, whether there is uneven contact of the teeth, whether the matching gear has proper backlash, and whether there is sufficient lubrication. If the gear is exposed, first install a safety cover, do not touch when the gear rotates. When there is noise and vibration during start-up, if there is insufficient lubrication after starting, please check the gear assembly correctly.
