Developing a range of Through Coolant toolholder adapters

在处理成形金属和其他刚性材料的机床制造部门，制造过程的一个组成部分是高精度切割。从刀具区域散热的传统方法是从外部喷嘴向切削区喷洒冷却液。这是一种无效的方法，因为冷却液不能深入切割部位。切割设备的速度-因此进给速度变慢，以防止与热有关的对刀具的损坏，并且产生的金属废料是热的和可塑性的，导致长屑自我卷曲。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，从而导致生产率下降。为了解决这个问题，山特维克拥有的SECO刀具开发了一系列刀具，其中冷却液直接从刀具本身出来，将集中的高压气流直接输送到刀具边缘，从而在冷却压力为70巴的情况下将生产率提高了50%。目前，JetStream技术是一种定制的解决方案，每次将刀具移动到不同的转塔工位时，都需要移除、改装和密封刀具后部的外部管道，这个过程需要大约45分钟。为了解决这个问题，山特维克提出了一种新的“贯通冷却液”刀具系列，可以直接安装在一系列不同制造商的机器上，而不需要定制管道。山特维克已经要求Craftsman Tools开发了一系列通过冷却液刀柄适配器的冷却液，使冷却液可以直接从机床工具通过到刀具，从而使其能够在高压下进入切割区。该适配器可实现2分钟的刀具更换，从而降低成本并提高生产率。

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.
