Problems solved by technology

[0008] 1. Since the cooling liquid channel is opened by stamping, the cooling liquid channel can only be a straight hole, and the cooling liquid does not flow smoothly in the flow channel
[0009] 2. If multiple blades are cooled at the same time, the flow rate of the coolant cannot be completely consistent, resulting in poor cooling uniformity
[0010] 3. It is not easy to have too many coolant channels, otherwise the overall strength of the tool will be deteriorated and it will be easier to damage
And affected by the number of coolant flow channels, the number of inserts in this method is limited, and the milling efficiency will also be reduced

Embodiment 1

[0053] Such as figure 1 As shown, a face milling cutter with a self-cooling and lubricating structure, the face milling cutter is integrally formed, suitable for occasions where the handle is short and does not need to consider the vibration damping effect, it mainly includes a handle 01, a face milling cutter body 02 and A plurality of milling cutter inserts 03; a plurality of milling cutter inserts 03 are evenly arranged on the face milling cutter body 02 along the circumferential direction; it also includes a cooling lubricant main channel 1 and a cooling lubricant secondary channel 2; a cooling lubricant main channel 1 is located in the tool holder 01 and is arranged along the axial direction; there are multiple cooling and lubricating fluid sub-flow channels 2, and the number is the same as that of the milling cutter blade 03; The shape of each cooling and lubricating fluid sub-flow channel 2 is connected to the cooling and lubricating liquid main channel 1, and the outle...

Embodiment 2

[0067] Such as image 3 As shown, due to the requirements of the use scene of the face milling cutter, the handle of the face milling cutter needs to be lengthened, so only the handle with the effect of vibration reduction can be used, and the 3D printing technology cannot produce the handle with the effect of vibration reduction now, so this The invention also designs another face milling cutter with a self-cooling and lubricating structure. The face milling cutter adopts a split structure of a handle and a face milling cutter body, which mainly includes a handle 01 (in this embodiment, the existing tool handle), face milling cutter body 02 and multiple milling cutter blades 03; multiple milling cutter blades 03 are evenly arranged on the face milling cutter body 02 along the circumferential direction; the face milling cutter body 02 is provided with a The step through hole 021, the damping knife handle 01 is inserted in the small diameter hole of the step through hole 021, a...

Abstract

The invention relates to a face milling cutter with a self-cooling lubricating structure. The face milling cutter comprises a cutter handle, a face milling cutter body and multiple milling cutter blades, a cooling lubricating liquid main flow way and multiple cooling lubricating liquid auxiliary flow ways are included, the cooling lubricating liquid main flow way is arranged in the cutter handle in the axial direction, the number of the cooling lubricating liquid auxiliary flow ways is equal to the number of the milling cutter blades, the cooling lubricating liquid auxiliary flow ways are matched with the face milling cutter body in shape, an inlet of each cooling lubricating liquid auxiliary flow way communicates with the cooling lubricating liquid main flow way, an outlet of each coolinglubricating liquid auxiliary flow way faces the cutting area of the milling cutter blades, and the cutter handle, face milling cutter body, the cooling lubricating liquid main flow way and the cooling lubricating liquid auxiliary flow ways are integrally formed through the 3D printing technology. The self-cooling lubricating structure in the face milling cutter can be reasonably arranged according to the actual cooling liquid flow direction, the cooling lubricating liquid circulates smoothly, and each cutting area in the face milling cutter can be evenly cooled.

Description

technical field [0001] The invention relates to a machining cutter, in particular to a face milling cutter with a self-cooling and lubricating structure. Background technique [0002] According to the processing type, the cutting process is mainly divided into: turning, drilling, milling, boring and grinding; [0003] Turning refers to the use of the rotary motion of the workpiece and the linear or curved motion of the tool to change the shape and size of the blank; drilling refers to the process of using the tool to process holes on the workpiece; The blade tool moves on the blank to cut the workpiece into the required shape and size; boring is a cutting process that uses a tool to enlarge a hole or other circular contours; grinding refers to the processing method of removing excess material on the workpiece with abrasives , which belongs to the finishing machining of mechanical processing; [0004] Face milling cutters are widely used in the rough machining stage of part...
