Technical Information Tunable Milling Tunable Milling Adapters The WIDIA™ Tuned Tooling System offers a full line of tunable milling adapters capable of performing at maximum output without the hindrance of vibration. Tunable milling adapters are through-coolant capable, and, because the internal damper can be adjusted to alleviate chatter, they provide optimum surface finish and longer tool life. General Guidelines for Milling with Extended Reach Adapters 1. Loosen both clamping screws. 4. Repeat Step 3 until good surface finish is achieved. You may need to use small increments to find an optimal position. 2. Turn the adjusting screw in the positive direction until it becomes snug. The adjusting screw becomes snug when it locks the tuner mass. 5. Back the adjusting screw off a 1/4–1/2 turn in the negative direction. 3. Turn the screw one complete turn in the negative direction and take a test cut. 6. Tighten both clamping screws and take a test cut to confirm desired results. 1. 2. 3. 4. 5. 6. *The TTS Milling Adapters will need to be re-tuned if the milling cutter is replaced with another with different mass.
