Description

[0002] In aircraft engines, the tenon and groove of the turbine disk is the basis for fixing the blades. In order to ensure structural strength, the tenon and groove of the turbine disk are milled from the entire profile. At present, the tenon and groove milling of aircraft engines is mainly carried out by CNC machining machines.

[0003] When the current CNC machine tools are milling the tenon grooves of aero-engine turbine disks, due to the high strength of the metal structure of the aero-engine turbine disk, the cutting of the milling cutter and the turbine disk causes the local temperature of the turbine disk to rise, so a large amount of coolant is needed for cooling.

In order to recycle the coolant, the bottom of the current processing equipment is often equipped with a structure for recycling coolant, mainly using a mesh separator.
