Li Quan came to Xu Zhenming to make suggestions.So he carried Xu Zhenming on his bicycle and rushed towards the mechanic repair workshop of the Nan Anjin quilt factory.
On the way, Xu Zhenming sitting on the bicycle bag rack asked Li Quan in a low voice: "Master! What milling cutter do you use to brush the plane?"
Brushing the plane is a folklore, referring to the meaning of milling a plane with a milling machine.The general process is to use the cutter head to install the alloy blade to brush the plane.This process is the fastest because the alloy blades are easily damaged and the cost is relatively high.
The guide rail of the CNC flame cutting machine designed by Xu Zhenming uses 40mm cold-drawn square steel as the raw material for the blank, which needs to be processed on three sides.All three surfaces are milled flat with a milling machine. After the workpiece is heated, side bending or arching is most likely to occur.Once this happens, the guide rail will be scrapped.
"Aren't you in a hurry to hurry up! Therefore, I arranged for Longmen Miller Master Hong to use a 100 cutter head to brush two guide rails at the same time. Unexpectedly, the guide rails will be arched before they are half brushed! Hey..." , Li Quan sighed.
He is solely responsible for the machining operations in the machine repair shop.After receiving the drawings from Xu Zhenming to process the guide rails, racks, gears, etc. of the CNC flame cutting machine, he immediately sent the drawings to the workers to start production without delay.
Fortunately, other workpieces are not difficult to process.Only the rack and the guide rail where the rack is installed are more difficult to machine, and deformation is most likely to occur during the processing.
In fact, Li Quan has already noticed this. He specifically explained to Master Hong, the operator of gantry milling, and asked him to pay attention to cooling and cooling the workpiece, so that the workpiece should not deform and bend after heating.Unexpectedly, this kind of thing still happened!
"100 cutter head is not good! This kind of cutter head has more contact surfaces with the workpiece, which is not conducive to the scattering of the shaving iron and the heat dissipation of the workpiece! The local heat of the guide rail is too high, and the phenomenon of deformation will occur!"
At this time, Xu Zhenming pointed out the root cause of the deformation of the guide rail.
While talking, the two of them had already arrived in the courtyard of the machine repair shop.
Master Hong, the operator of gantry milling, was squatting on the ground and smoking a suffocating smoke, his face was full of misery.After seeing Xu Zhenming and Li Quan coming back on their bicycles, his eyes lit up, throwing away half of the cigarette in his hand, and trotting towards Xu Zhenming!
"Boss Xiao Xu! Now, these guide rails and racks can't produce qualified products! Do you have a fast and good way?"
Master Hong asked Xu Zhenming with a flushed face.He felt very uncomfortable. After the workpiece was scrapped, half of his desk fee was gone, and the bonus would also be affected!
Looking at the somewhat frustrated Master Hong, Xu Zhenming came up with his own processing plan: "Use a flying knife to brush the plane, and then use diesel as the coolant, and constantly cool the workpiece. This should be solved!"
Flying knife is a folk saying, in fact, it is to install a cutter bar on the milling cutter head, and install an alloy knife on the cutter bar horizontally.When the milling cutter head is working, the alloy cutter rotates at a high speed along the cutter bar, like a knife wing.Therefore, folks call this method the flying cutter milling process.This kind of technology is good for discharging the shaving iron of the machined parts, the processing speed is slow, and it is good for the heat dissipation of the workpiece!
"Can flying knives work?"
"Is it a waste to use diesel to cool down?"
After hearing about the processing technology arranged by Xu Zhenming, Master Hong, Li Quan and others all expressed skepticism.Old workers like them have also heard of the use of diesel cooling method to cool the workpiece, but they have no personal operating experience.So these people are a little hesitant!
However, Xu Zhenming is the boss with a big mouth.After hearing his instructions, everyone got busy, re-worked the fixtures, and re-clamped a 40mm cold-drawn square steel on the gantry milling table.
This time, Xu Zhenming is going to personally brush the first surface of the workpiece.
He was standing near the workbench of the gantry milling machine with a small pot in his hand and a brush in his hand.The small tank is filled with diesel fuel, which is used to cool the flying knife and the workpiece.According to the speed of the flying knife, he dipped a little diesel oil with a brush from time to time, and dipped it on the working surface of the tool and workpiece.The movements are very skillful and the rhythm is very strong!
"Boss Xiao Xu has a very good technique in operating gantry milling!"
"This method seems to be effective, the temperature of the workpiece is not high, and it has been unable to come up!"
"Use diesel as a coolant, and smoking must not be allowed in the workshop! Otherwise it will cause a fire!"
After seeing this scene, Li Quan, Master Hong, and the workers on the night shift were all talking quietly.They are all waiting to see the effect of the first cut of the gantry milling.
After an hour, Xu Zhenming finished rough milling the first surface of the guide rail."Master, Master Hong! Just follow my method!" He told everyone with a smile.
Li Quan still didn't believe it. He thought that the workpieces milled by this process would still be side-shaped, either side-bending or arching.They and Master Hong and others quickly dismantled the fixture on the guide rail and began to measure the workpiece with a table ruler and vernier caliper.
After removing the tooling, the guide rail workpiece is already in a free state, and the amount of arching or bending deformation can be revealed at once.
Li Quan used a table ruler to measure the thickness of the workpiece. From beginning to end, there is a data, and the workpiece has no arch deformation!
Master Hong used a vernier caliper to measure the width of the workpiece. From the beginning to the end, there is one data, and the workpiece has no side bending deformation!
Both of them are experienced, and they touch the processed surface of the workpiece from time to time.Seeing that the temperature of the workpiece was not high, the two of them couldn't help but laughed in relief: "This method is good! Slow is a bit slower, and the precision of workpiece processing can be guaranteed!"
Now, Master Hong and Li Quan, as well as the workers in the workshop, have to be convinced by Xu Zhenming's experience!The craftsmanship demonstrated by Xu Zhenming is known to them, but they have never used them together!
"Master Hong! The following processing techniques follow the method demonstrated by Naruko!"
At this time, Li Quancai arranged work with a smile on his face.He works cautiously and does not dare to make casual decisions without seeing the real results.
"Coco..." A cooing sound came from Xu Zhenming's stomach, and Xu Zhenming remembered that he had not eaten dinner yet.Similarly, none of the milling machine workers in the workshop had dinner.Seeing this situation, Xu Zhenming smiled and said: "I asked Liu to bring some food from the cafeteria of Yiming Company. Everyone has to bear with me!"
Hearing this sentence, everyone laughed happily.
Li Quan came to Xu Zhenming to make suggestions.So he carried Xu Zhenming on his bicycle and rushed towards the mechanic repair workshop of the Nan Anjin quilt factory.
