TetraMini-Cut – camera adjustment ring – AH8005
IMPROVE TOOL LIFE
For grooving operations on HPM38 camera adjustment rings using a CNC lathe, the previous tool suffered from significant burr formation and extremely short tool life, making stable machining difficult.
By implementing Tungaloy’s TetraMini-Cut with wear-resistant AH8005 grade—engineered for hardened materials and featuring a high-hardness PVD coating—the process achieved excellent resistance to built-up edge and stable performance.
As a result, tool life improved dramatically, with the number of parts processed per edge increasing from 5 to 120, representing a 24-fold increase. This enabled greater process reliability and a substantial reduction in tool change frequency.
