Anyone with machinist abilities working with one of these machines quickly realises the need for spindle speed when working with aluminum and small diameter cutters. I have an older RF-45 with the 3 phase / 2 speed motor. This gives a max spindle speed of 3000 rpm. Almost all my work is done using high helix end mills at max speed. This machine is really noisy at high rpm and does it ever generate heat. After a few hours use, you feel like you are standing next to a woodburning stove. Changing to a timing belt drive with an inverter speed controlled 3 phase motor is the way to go. Doing so would reduce noise by probably 75% and cut power consumption and associated heat by a huge amount. Can anyone help with any design info already available??? |
