Industrial roller brushes, curved toilet brushes and round cleaning brushes are the most typical models made by 3-axis machines. 1) If the original plastic brush pieces are moulded without holes, a 3-axis 3-head machine with functions of both drilling and tufting is strongly recommended. Please take a look at this machine making roller brushes, you'll fully understand the working principle. 2) If the plastic brush pieces are already moulded with holes, then only a 3-axis tufting machine is needed. Both this machine making round body-cleaning brushes and the one making curved toilet brushes are just perfect examples. Contact us now to clear your doubts.
