When using our newer generations of split-frame lathes such as the RBL-G2 and the high-performance TRIMAX machining system (that are configured with direct drive motors) you must be careful not to overheat the tooling by operating at too high of a surface speed. This can rapidly damage or destroy tool bits.
Our advanced bits are designed to achieve precision angles and prep profiles based on the type of material you are cutting. Legacy model clamshell motors typically used right-angle gear reduction inputs to overcome the machine’s higher torque loads. That resulted in higher cutting forces at lower surface speeds.
The new TRIMAX patented recirculating ball-bearing system offers increased rigidity and power transfer but at greatly reduced torque resistance. This means that if an operator is unaware or not observant of the desired bit surface speed for the material and cutting situation, the machine is capable of running much faster than the maximum permissible bit speed.
Always refer to your machine’s Operator Manual for more info on the optimal cutting speed. If you have questions, or are working with non-typical materials, contact Tri Tool to ensure you get the best results and tool bit life possible.
