チタン合金加工工具寿命最適化。加工パラメータの即座のCoolant to Add (L), Water to Add (L), Final Volume (L)を取得。
悪い数値のコストは？典型的なジョブショップシナリオで計算してみましょう。もし クーラント濃度計算機 が15%攻撃的すぎる場合、 Nachi エンドミルを余分に買うだけでなく — 予期しないダウンタイム、手直し、納期遅れのコストを払っています。
| Premature Kennametal tool failures | $6,400/yr |
| Unplanned machine downtime | $12,200/yr |
| Rework / scrap parts | $8,700/yr |
| Excess Haimer holder wear | $2,100/yr |
| Total Annual Loss | $29,400/yr |
シナリオを逆にしてみましょう。クーラント濃度計算機を最適化 — メーカー推奨の開始パラメータを特定のNachiまたはKennametal工具に使用し、Starrettプリセッターで検証 — することで年間約3万ドルを回収できます。これは新しいDMG Mori工具プローブまたは1年分のNachiインサートに相当します。
ROIは即時。最初のパーツが最適化され、最初の節約日。
Maintaining correct coolant concentration is critical for tool life, surface finish, and sump life. This calculator determines how much concentrate or water to add when your refractometer reading is off target.
General machining steel: 7-10%. Aluminium: 5-8%. Stainless and superalloys: 8-12%. Grinding: 3-5%. Always follow the coolant manufacturer's recommendation — concentration too low causes rust and bacterial growth; too high wastes coolant and may cause skin irritation.
Use a handheld refractometer (Brix scale). Take a sample from near the coolant nozzle (not from the sump surface). Apply 2-3 drops to the prism, close the cover, and hold up to light. Multiply the Brix reading by the coolant's refractometer factor (typically 1.0-2.5 — check the product data sheet).
Check weekly as a minimum. Check daily for high-production machines or when running multiple shifts. After heavy coolant loss (carry-out on parts/chips), top up and re-check. A daily log of readings helps spot trends before problems occur.
Measure your current concentration with a refractometer. Enter the current %, target %, and sump volume in litres. The calculator tells you exactly how much concentrate or water to add to hit the target.
