Abstract

A nozzle for cooling lubricant is described having a connecting chamber with a chamber inlet and with a deflector plate in the interior of the connecting chamber that is held on at least two mounting means, a main chamber that is removably mounted by the rear face on the front face of the connecting chamber and has a diffusion plate with drilled holes, and a nozzle plate that is removably mounted by the rear face on the front face of the main chamber and has a hole pattern adapted to a grinding wheel profile.

Claims (24)

1. A nozzle for cooling lubricant, comprising:

a connecting chamber with a chamber inlet and with a deflector plate mounted in an interior of the connecting chamber,

an assembly including a main chamber and a diffusion plate with drilled holes, the main chamber and the diffusion plate overlapping each other to define a two-layer structure, a rear face of the two-layer structure being removably mounted as a block on a front face of the connecting chamber, and

a holed nozzle plate including a hole pattern configured to match with a grinding wheel profile, a rear face of the nozzle plate being removably mounted on a front face of the main chamber.

2. The nozzle according to claim 1 , wherein the deflector plate has no drilled holes for passage of the cooling lubricant.

3. The nozzle according to claim 1 , wherein the diffusion plate is installed with drilled holes in a bottom of the main chamber and wherein the drilled holes extend over an entire inner surface of the bottom of the main chamber.

4. The nozzle according to claim 1 , wherein the deflector plate is positioned in the connecting chamber above the chamber inlet such that the cooling lubricant is distributed in the connecting chamber before it impinges on the diffusion plate of the main chamber and a size of the deflector plate is at least 50% of an inner surface of a bottom in the connecting chamber.

5. The nozzle according to claim 1 , wherein the deflector plate is disposed parallel to a bottom of the connecting chamber.

6. The nozzle according to claim 1 , wherein the front face of the connecting chamber and the front face of the main chamber have grooves for O-rings.

7. The nozzle according to claim 1 , wherein the connecting chamber, the main chamber, and the nozzle plate have screw openings for connecting.

8. The nozzle according to claim 1 , wherein the connecting chamber, the main chamber, and nozzle plate are connected by screws in screw openings and O-rings in grooves to form a device.

9. The nozzle according to claim 1 , wherein the drilled holes in the diffusion plate have a diameter of 2 mm to 4 mm and drilled holes in the nozzle plate have a diameter of 1 mm to 3 mm.

10. The nozzle according to claim 1 , wherein the connecting chamber with deflector plate, main chamber, and nozzle plate contain aluminum or alloyed high-grade steel.

11. A method of emitting a coherent jet of cooling lubricant onto a grinding wheel comprising:

providing the nozzle for cooling lubricant according to claim 1 ,

adapting the nozzle plate with the hole pattern to the grinding wheel profile,

setting a desired cooling lubricant flow rate which corresponds to a specific cooling lubricant pressure for a grinding process, and

setting a specific grinding wheel peripheral speed.

12. The method according to claim 11 , wherein the desired cooling lubricant flow rate corresponds roughly to the specific grinding wheel peripheral speed.

13. The method according to claim 11 , wherein a laminar flow is created by the nozzle for cooling lubricant.

14. A method comprising:

providing the nozzle for cooling lubricant according to claim 1 , and

supplying cooling lubricant to a point of contact between a workpiece and a tool for removal of material.

15. The method according to claim 14 , wherein the supplying is done during grinding processes.
