CNC milling, flying surface, how to match the number of revolutions and the tool

There are many brands of CNC gantry milling machine on the market, mainly depending on the sales of that brand and the large number of customers. 80% of the sales share of CNC gantry milling machine in the market belongs to Guda Machinery brand machine tools, and the other 20% share has some brand products such as Jin Jiarun and Yagu. Guda Machinery sales release is very extensive, there are customers all over the country, foreign customers are more pro-Guda Machinery brand CNC gantry milling machine products.

Its products have obtained the EU CE compulsory product certification, and the product quality is guaranteed.

Different working conditions, product materials, product hardness, and product surface quality will affect the selection of parameters.

There is no absolute method for this collocation, it is all explored by yourself, or you can tell your machining situation to the tool manufacturer and ask them to recommend the parameters for you.

Usually.

The higher the number of revolutions, the higher the cutting efficiency and the faster the tool wears.

The faster the pass, the higher the cutting efficiency and the worse the surface quality.

I do CNC tool sales and technical work.

Generally, we select the tool to determine the parameters will have the following steps.

1. Determine the type of tool according to the shape of the product that needs to be processed, is there any interference? How big is the tip fillet? What about rigidity? ）

2.Select the blade material according to the product material.

Machining aluminum alloys, steel parts, cast iron, stainless steel, superalloys their material parameters vary greatly)

3.The tool geometry is determined according to the machining status.

Usually large rake angle is used for finishing, non-ferrous metal machining, soft material machining).

Negative rake angle is used for interrupted cutting, heavy machining and other places with bad working conditions).

4.After the blade is selected, the machining parameters will be determined according to the tool company information.

Each tool company will have each recommended cutting data on their product data, and usually I will use 70% of their recommended parameters for the first cut. Then adjust it according to the situation of the first cut).

Let me give you an example.

The customer gave me a gearbox drawing and asked me to choose the roughing face mill and confirm the machining parameters.

First of all, I will look at the drawings to see if there are any interference and special processing parts. After inspection, it was found that there was no interference and the rigidity was very good.

Therefore, from the point of view of cost performance, I will choose the HNHX 1006 ANTN milling cutter with 12 tips on both sides, and since it is made of cast iron, I will choose our TT6080 material specifically for machining cast iron. Since it is rough machining and has good rigidity, I will choose a blunt geometry to improve the wear resistance, so I chose M, so my tool model is selected, HNHX 1006 ANTN-M TT6080. The parameters recommended in our catalogue for this model of blades are:

Generally the first time I go to 75% so that the parameters come out.

The method of adjusting the speed parameters of the flying cutter head of the CNC lathe is as follows: first press the "F" key to change the speed, and select the corresponding speed parameter on the CNC display screen. Then, by adjusting the feed rate and cutting depth of the Changbu cutting tool and workpiece, the machining is carried out to match the rotational speed.

In the adjustment process, it should be noted that when the speed of the high speed is fast, the feed rate and cutting depth should be appropriately adjusted to avoid overheating and loss. On the contrary, when the speed is slow, the feed rate and cutting depth should be appropriately increased to ensure the processing efficiency.

In the milling operation of the flying cutter head of the CNC lathe, the method of adjusting the speed parameters is as follows: 1First, on the operation interface of the CNC lathe, find the "Parameter Settings" or "System Settings" option.

2.After entering the parameter setting interface, find options such as "Spindle Speed" or "Flying Knife Speed". 3.

Confirm that the current set speed parameters are correct, and if you need to adjust them, you can set them according to the speed range of the machine and the size of the tool. 4.After the adjustment, save the settings and exit the parameter setting interface.

5.When carrying out the flying cutter head milling operation, adjust the feed rate and cutting depth and other parameters according to the needs to ensure the safety of operation and processing quality. It should be noted that when adjusting the speed parameters of the rotating forest, it is necessary to operate in accordance with the operation manual of the machine tool and the instructions for the use of the tool to avoid safety accidents.

At the same time, it is also necessary to select appropriate tools and cutting parameters according to the processing materials and requirements to ensure the processing efficiency and processing quality.

Use the face mill to mill out two planes on the shaft, how to set the tool, how to walk the tool.

Hello dear <>

Tool setting method: Use the magnetic gauge holder to suction the lever dial gauge on the spindle of the milling machine. Enter manually in manual mode"mo3 s50"The command causes the spindle to rotate at low speed.

The machine tool is manually operated by a hand-cranked pulse generator, and the meter head rotated by the random bed spindle is gradually approached to the surface of the workpiece in the order of x, y, and z. Move the z-axis and press the gauge into the surface of the workpiece about 011mmGradually reduce the amount of movement of the hand-cranked pulse generator, so that when the gauge rotates for one time, the runout of its pointer is within the allowable tool setting error (such as 0101mm), and it can be considered that the rotation center of the spindle coincides with the center of the measured hole.

Make a note of the coordinate values of x and omission y in the coordinate system of the machine tool at this time. The tool setting accuracy of the dial gauge of the bar search bar is high, but the efficiency is low, and the accuracy requirements for the measured hole are also high (generally the measured hole is required to be reamed or bored).Knife setting steps:

The milling cutter ready for machining is mounted on the spindle; In the manual mode, the manual input "M03S300" command is used to rotate the spindle at medium speed; Manually move the milling cutter so that it is close to the side of the workpiece to be measured in the x-direction, and its z-direction position should be lower than the position of the upper surface of the workpiece, until the circumferential edge of the milling cutter slightly touches the side of the workpiece; The relative coordinate x of the machine tool is cleared, and then the milling cutter is withdrawn from the workpiece in the Z direction; Move the milling cutter to the other side of the workpiece, repeat the step; Write down the relative coordinate value of the machine x at this time; After retracting the cutter from the workpiece in the Z direction, move it towards the center of the workpiece until the relative coordinate value of the machine is x 2At this time, the mechanical coordinate value of X displayed by the machine tool is the X-axis mechanical coordinate of the center of the workpiece; Along the y-direction, repeat the step to obtain the y-axis mechanical coordinates of the center of the workpiece. The tool test cutting method is simple, but it will leave marks on the workpiece, and the tool setting accuracy is low.

In order to avoid damage to the workpiece, a feeler gauge can be added between the tool and the workpiece when setting the tool. Since feeler gauges are added on both sides of the workpiece, the thickness of the feeler gauge can not be considered. If the accuracy of the tool setting is high, the tool can be replaced with an edge finder.
