N P K H M S General recommendation Exceptions for material ranges P K When coolant is not available the cutting speed (vc) and/or the radial feed (ae) should be reduced. The resulting reduced temperature reduces the risk of thermal shock. If there are chip evacuation problems the application of coolant should be taken into consideration, poor evacuation of chips can lead to massive tool wear and even tool breakage. When heat is being generated due to poor chip evacuation , it should be checked if through coolant is available. By using a specifically directed “coolant jet”, coolant can be supplied where congested without hitting the cutting area. Alternatively, the application of coolant for the entire machining operation is recommended. Other notes Finishing The application of coolant is principally an advantage as a better surface finish can be achieved. Very long tools Coolant can result in a smoother process, as the lubricant has a vibration-reducing e ect. Alignment of coolant • as acurate as possible in the cutting area from at least three directions • no flushing back of small chips to the cutting area Solid carbide milling cutters with internal cooling • optimal chip evacuation, very good cutting edge cooling, very e ective against built-up edges • to be recommended especially for larger tool diameters and tough materials Peripheral cooling /Guhrojet Best external option: Optimal tool cooling and chip evacuation thanks to the direct route from coolant exit to cutting area Steel • Avoid thermal shock • Dissipate machining temperature via chip • Supporting chip evacuation Cast iron Dry machining, compressed air, MQL: Hardened Stainless Soluble oil, neat oil: • Cooling of tool cutting edge • Preventing built-up edge • Supporting chip evacuation Special alloy Non-ferrous metals Soluble oil, neat oil: • Preventing built-up edge • Supporting chip evacuation GÜHRO JET Tool cooling 一般建議 乾式切削、噴壓縮空氣、 MQL 霧化切削液冷卻 避免熱產生對刀具的衝擊 切屑把熱帶走 幫助排屑 乳化液、純油性 切削刃口冷卻 避免刃口沾黏積屑 幫助排屑 乳化液、純油性 材料範圍以外的注意事項 如果沒有冷卻條件不佳，則應該降低切削速度（ vc ）及降低切寬（ ae ），這樣才能降低溫度，降低熱對刀刃的衝擊風險 如果排屑不良有問題，則應考慮使用冷卻液，排屑不良會大大導致刀刃磨損甚至斷刀。 當排屑不良而產生熱能時應檢查是否可以使用冷卻液，透過使用專門的“冷卻液噴嘴”，可以將冷卻液供應到堵塞處而不會碰到切削區域， 另外，建議在整個加工過程中使用冷卻液。 其他注意事項 使用冷卻液原則上是一個優勢，因為可以實現更好的表面光潔度 使用冷卻液可以使加工過程更順暢，因為潤滑劑具有減振作用 至少有三個方向的切削液噴嘴，需對準切削區域噴射 不要將小切屑衝回切削區域 最佳的排屑性，非常好的切削刃口冷卻，避免刃口沾黏積屑非常有效 特別推薦用於較大尺寸的刀具和堅韌的難切削材銑削 由於冷卻液直接噴到切削區域，達到最佳的刀具冷卻和排屑性 精銑削 A.
