Summary: A better process combination of high-pressure cooling system for CNC deep hole drilling can be achieved through high-pressure cooling system, open drilling groove, coated alloy tool and single retreating. The above conditions are the successful realization of deep hole processing by CNC deep hole drill. Basic requirements.

1. Using CNC deep hole drill to process deep holes, solid equipment structure, good shock absorption performance, and as small as possible axial runout are necessary to ensure deep hole processing accuracy, repeated positioning accuracy and surface roughness.

2. The drill bit geometry of the proper CNC deep hole drill bit can make the deep hole processing more effective.

3. Through the shaft high-pressure cooling system, debris can be seamlessly removed, the spindle speed and entry speed can be increased, and the tool life can be extended.

Through shaft cooling, the precise geometry of the drill, alloy tools, cutting parameters of the reasonable choice is an important factor in deep hole processing, affecting the hole size accuracy, surface roughness, processing cycle, tool life and so on.

CNCHigh pressure cooling system for deep hole drillingTechnical advantages

In modern processing, in order to effectively apply the coolant, it is necessary to use more high-pressure spray cooling, the flow rate is large enough, and the spray direction needs to be accurate. High pressure cooling has greater advantages than regular cooling methods in many aspects, such as chip formation, cutting heat distribution, surface integrity, tool wear, good adhesion of the workpiece material and cutting edge.

1, the cooling effect.

The high-pressure cooling technology accurately sprays the high-pressure coolant to the cutting area (heat-affected zone) between the blade front surface and the chips, which greatly increases the heat of the cutting area, makes the coolant perform well, and achieves rapid cooling. the purpose.

2. Chip control capability.

The use of high-pressure cooling can effectively reduce the cutting heat in the cutting area, make the chips brittle and easy to break, thereby obtaining short chips, so that the chips are no longer entangled. The distribution of cooling water pressure and nozzle size have a great influence on iron filings. Adjusting jet parameters can achieve a variety of dandruff effects, thereby improving dandruff length. In addition, a high-pressure wedge is formed in the cutting area, so that chip breaking can also be forced. Then reduce the impact of chips on the processing effect.

3, tool life.

With the high-pressure cooling method, the coolant nozzle can be closer to the cutting edge of the blade, and the coolant can accurately reach the cutting area between the front of the blade and the chip, thereby improving the cutting control and the cooling effect of the cutting edge, thereby reducing tool wear and extending tool life. Generally, increasing the cutting speed will shorten the tool life, but using the high-pressure cooling method, increasing the feed speed will not significantly shorten the tool life.

4-Competitiveness.

The high-pressure cooling method can better control the debris, reduce the temperature more effectively, perform operations without stopping the machine, shorten the processing cycle, make the processing process safer and more reliable, longer tool life, higher surface quality of parts, and improve processing Efficiency and quality, reduce processing costs. CNCHigh pressure cooling system for deep hole drillingTo further improve the comprehensive competitiveness of enterprises, high-pressure cooling technology refers to the cooling water pressure rise to a certain pressure, through the internal cooling water channel, through the nozzle accurately sprayed to the required cooling area, in order to achieve the purpose of rapid cooling. High-pressure cooling (HPC) is very effective for general processing applications, especially stainless steel and low-carbon steel, and it is also excellent for processing difficult-to-process materials such as titanium alloys and heat-resistant high-temperature alloys for aviation materials.
