NEW coolant through the tool application for quill feed units
  套筒式自进给动力头刀具中冷最新应用
  What is the main purpose for coolant application? Of course among many reasons primarily for the lubrication and cooling of the cutting edge and in addition to help facilitate chip evacuation.
  In cooperation with REGO-FIX©, SUHNER developed an attachment for the cost effective and efficient application of coolant-lubrication liquids through the tool, specifically designed for quill feed drilling units.  
  中冷应用的主要目的是什么?当然在多种原因内,首先是对刀具的润滑和冷却,除此之外,还有助于切屑的移除。
  在与REGO-FIX®合作后,SUHNER开发了低成本、高效率的刀具内冷应用的附件,是为套筒式自进给动力头专门设计的。

Optimizing the cooling and lubrication effect to help increase chip removal, tool life and performance requires the coolant-lubricant mix in direct contact with the cutting edge of the tool. Namely for drilling operations, internal coolant becomes more and more essential. In the past, the application of an internal pressurized coolant-lubricant mix, especially for quill feed units, presented challenges and complications.
  最优化的冷却和润滑效果,有助于切屑移除,刀具寿命和精度要求冷却润滑混合液直接作用于刀具切削刃。以钻孔作业命名,内冷功能变得越来越必需。在过去,内部增压冷却润滑混合液的应用,特别是套筒式自进给动力头,会出现质疑和纠纷。
  A new approach engineered by REGO-FIX© is called ReCool© where the coolant-lubricant mix enters the collet from radial direction and then passes through the tool. It is very simple and effective. Based on this idea, SUHNER adapted the ReCool© principle and designed attachments for the application of  internal coolant liquids for its MONOmaster© and MULTImaster© families of quill feed drilling units.
  REGO-FIX©设计新的方法被称为ReCool©,冷却润滑混合液径向进入夹头,然后流过刀具中心。这是非常简单和有效的。基于这个理念,舒能采纳了ReCool©的原理,为舒能套筒式自进给钻孔动力头MONOmaster和MULTImaster家族设计了内部冷却液应用的装置。
  Drilling with coolant through the tool application typically allows for a 20% increase in surface cutting speed, which results in higher chip removal rates and drastically reduces the machine cycle time. 
  典型的内冷刀具应用的钻孔方式,许可了表面切削速度的提升20%,有切屑快速去除的结果,大大的降低了机床节拍时间。
  This solution allows us to retrofit SUHNER quill feed units with internal coolant supply even on existing machines in a very clever uncomplicated way, thus providing increased benefits in machine efficiencies and production time. 
  这种解决方案,允许我们改进了舒能自进给动力头,使其具有内冷应用,甚至以非常灵巧简单的方式改善现存的机床,以此在机器效率和生产时间获得了增多的益处。
