In the machine tool manufacturing sector, which deals with shaping metal & other rigidmaterials, an integral part of the manufacturing process is high precision cutting. Theconventional method of removing heat from the cutting tool area is spraying coolant from anexternal nozzle onto the cutting zone . This is an ineffective method as the coolant is unable topenetrate deep into the cutting site. The speed of the cutting equipment & hence feed rate isltd to prevent heat related damage to the cutting tool, and the metallic waste product that isproduced is hot & malleable, resulting in a long swarfe that curls in on itself. Poormanagement of this waste product can result in damage to the machinery, so the machinemust be regularly switched off to dispose of it, resulting in decreased productivity.To tackle this problem, SECO Tools, owned by Sandvik, have developed Jetstreamtooling, a range of cutting tools where the coolant comes directly out of the tool itself,delivering a concentrated, high pressure stream straight to the cutting edge, resulting in a>50% improvement in productivity at a coolant pressure of 70 bar. Currently, Jetstreamtechnology is a bespoke solution, involving the removal, refitting and sealing of an externalpipe to the back of the cutting tool each time a tool is moved to a different turret station, aprocess that takes ~45 mins.In order to overcome this problem Sandvik have proposed a new range of ‘Through Coolant’cutting tools that can fit directly onto a range of different manufacturers’ machines withoutthe need for bespoke piping. Sandvik have asked Craftsman Tools to develop a range ofThrough Coolant Toolholder Adaptors whereby the coolant can pass directly from themachine tool through to the cutting tool, allowing it to be directed at high pressure into thecutting area. This adapter will enable a 2 min tool changeover, leading to decreased costs &increased productivity.

在加工金属和其他刚性材料的机床制造领域，高精度切削是制造过程的一个组成部分。从切削刀具区域去除热量的传统方法是从外部喷嘴向切削区域喷射冷却液。这是一种无效的方法，因为冷却剂无法深入到切割部位。切削设备的速度和进给量限制是为了防止切削刀具的热相关损坏，并且产生的金属废料是热的和可锻铸的，导致自身卷曲的长切屑。这种废物管理不善会导致机器损坏，因此必须定期关闭机器以处理它，导致生产力下降。为了解决这个问题，山特维克旗下的SECO工具公司开发了jetstreamtools，这是一系列切削工具，冷却剂直接从工具本身流出，将集中的高压流直接输送到切削刃，在冷却剂压力为70 bar的情况下，生产率提高了50%。目前，jetstream技术是一种定制解决方案，每次将切削工具移动到不同的转塔站时，都需要拆卸、改装和密封切削工具后部的外部管道，整个过程大约需要45分钟。为了克服这个问题，山特维克提出了一系列新的“通过冷却剂”切割工具，可以直接安装到一系列不同制造商的机器上，而不需要定制管道。山特维克要求Craftsman Tools开发一系列通过冷却剂刀架适配器，使冷却剂可以直接从机床通过切削工具，使其在高压下直接进入切削区域。该适配器可实现2分钟的刀具转换，从而降低成本并提高生产率。
