Definitions
- the present invention relates to the field of tools for machine tools.
- the present invention relates in particular to the field of cutting tools for machine tools and more precisely to the field of cutting tools with integrated lubrication.
- the present invention relates in a first aspect more specifically to a cutting tool with integrated lubrication having a directional sprinkler ring allowing first to guide the lubricant as close as possible to the cutting part of the tool and
- the present invention also relates in a second aspect to an integrated lubrication cutting tool having a plurality of lubrication channels extending into the tool body.
- Lubricants can be routed near the cutting edges of tools in many ways. The most common method is to lead the lubricant through one or more hoses located around the cutting area. So, today, the majority of machine tools, machining processes and cutting tools use external coolant.
- External watering has several drawbacks which become particularly troublesome in the case of small tools.
- an external coolant does not allow optimal chip evacuation, which often means that the cutting edges of the tools cut the same chips several times. This results in poor surface conditions, or even untimely tool breakage.
- the outlet holes of the lubrication channels are placed in an intermediate part of the tool which is located between the body of the tool and the cutting part of the latter.
- the solution of integrated lubrication with peripheral watering is not completely satisfactory.
- the lubricant is not sufficiently directed towards the cutting part of the tool, which results in insufficient lubrication.

- the problem of cutting back stuck chips creating poor surface conditions, common with external lubrication processes, is eliminated.
- the lubricant also reduces the formation of built-up edges and contributes to a better surface condition of the part produced. In general, the life of the cutting tool is increased.
- Another advantage is to allow reliable and repetitive machining with tools of dimensions less than 0.30 mm in very difficult machinable materials such as titanium, high temperature alloys, carbon fibers, etc.
- the object of the present invention brings new perspectives to high rotational speed machining. It makes it possible to use the latest generations of machine tools with very high rotation spindles equipped with internal air and oil micro spraying and the first carbon dioxide cooling and cooling systems.

- the tool body comprises 2, 3, 4, 5, 6, 8 or 10 lubrication channels. This increases the flow of lubricant and improves the lubrication of the cutting part.
- the lubrication channels extend through the tool body parallel to the central axis. Such an embodiment allows the lubrication channels to be produced in a particularly simple manner.
- the lubrication channels extend through the tool body in a spiral around the central axis.
- the directional sprinkler ring is removable. This allows the directional coolant ring to be exchanged if it is damaged or if another ring with a different shape is more suitable for the specific use of the cutting tool.
- the tool head is a two-size, face-cut and cut-to-diameter milling head having one to ten sharp teeth.
- the tool head is a whirler or a thread mill.
- the tool head is a drill bit.
- the technical advantage is that it prevents long chips from winding up on the body of the drills, forcing operators to stop the machining process.
- the tool head is a reamer.
- the technical advantages are to lubricate the cutting area but also to prevent long chips from winding up on the body of the reamers.
