In collaboration with our tooling partner, Sandvik Coromant, take a look at the trochoidal milling and turning operations available on our all our driven tool HWACHEON lathes. The live tooling on show in the video below is on our brand new, Hwacheon HiTECH 450CXLYMC, available from stock now - with in person demonstrations in Sheffield !
Advantages of Trochoidal Milling
- Decreased cutting forces
- Reduced heat
- Greater machining accuracy
- Improved tool life
- Faster cycle times
- One tool for multiple slot sizes
Trochoidal milling can be very advantageous in certain applications. The reduced radial engagement of the cutting edge decreases the amount of heat produced in the cut while also decreasing the cutting forces and load on the spindle. The reduced radial forces allow for greater accuracy during production and make it possible to machine finer and more precise features on a part.
In addition, the lower radial depth of cut allows for a higher axial depth of cut, meaning that the entire length of the cutting edge can be utilized. This ensures that heat and cutting forces are distributed across the tool’s cutting edge, rather than concentrated on a single section. The reduced heat and wear, combined with their uniform spread on the cutting edge, resulting in significantly improved tool life over conventional slotting methods.
Given the reduced destructive forces, the cutting tool’s speeds can be increased. Since the entire length of cut is utilized, trochoidal milling can eliminate the need for multiple axial depths of cut. Increased running parameters and a reduced number of passes greatly reduce cycle time.
