High Speed Trochoidal Cutting with Mini Mini Chuck
During a recent visit to the NIKKEN Innovation Centre, Wedco ran their 12mm diameter ‘Twist’ end mill for a trochoidal rough milling process in steel (similar material grade to S55C).
This test cut was developed further by NIKKEN Engineers and reached considerably greater cutting parameters to those originally recommended and witnessed by Wedco during their visit, with a resulting depth of cut of 36mm – 3xD.
The original recommended parameters were 250m/min which was still impressive during cutting. A total of 3 slots were machined in the block at an increased feed rate of Vc 350m/min and the parameters and cutting remained very stable and reliable.
Cutting Tool: Wedco Twist 12005 End Mill
Machine Tool: Doosan DNM5700
Speed & Feeds
Vc - 350m/min dry cutting with air blast only
Fz - 0.109mm
Ae - 1mm
Ap - 36mm
MRR - 181cm3
This application demonstrates the holding force and rigidity of the Mini Mini Advanced Alpha toolholder, making it suitable for arduous machining duties on intricate, hard-to-reach features due to its’ small nose diameter and wide range of gauge lengths.
