Today we come to give a detailed example of how an ordinary vertical milling machine is transformed into a CNC vertical milling machine. Now a lot of customers engaged in the machining industry, found that ordinary vertical milling machine processing speed, efficiency and accuracy is low, but if the procurement of common processing center and CNC machine tools, the cost is too high, take too much money. Many customers reflect this situation to us, hoping to improve the processing efficiency and precision of ordinary milling machines. After my company's technical team of R & D and transformation, our XQ6232WA transformed into a CNC vertical milling machine, greatly improving the processing efficiency and accuracy. Here we compare the transformation of the machine with the original machine after the difference.

1. Drive different: figure 3 and 4 show the assembly of the elevator.

From the figure we can see that the ordinary vertical milling machine transmission mechanism is carried out by the gear meshing transmission, and CNC vertical milling machine is used servo drive, remove a lot of gear.

2. Screw different: ordinary vertical milling machine is used in ordinary T-type screw, while the CNC vertical milling machine is used in the ball screw. Ball screw with the benefits of servo controller is to control the high precision of the machine, in the processing of the workpiece can also be followed by milling milling, and ordinary screw in the mechanical processing can only reverse milling.

3. System: CNC vertical milling machine is used the CNC system from Guang Tai, and ordinary vertical milling machine only has a digital display.

The rest of the transformation of the basic same as above, such as the table and so on. The cost of the machine is much lower than that of the ordinary CNC milling machine, but it is not much worse in performance. It can also be programmed on the machine tool to realize automation and batch processing.

With the continuous development of the market and the continuous improvement of industrial level, people are increasingly demanding mechanical automation.

With the continuous improvement of labor costs, intelligent products continue to develop, CNC products have entered the machinery industry. The initial stage generally through the ordinary vertical milling machine, horizontal milling machine with CNC system, to achieve CNC machine automation. For example: SK5032, SK6132 is through this transformation of the production of products.

Whether the vertical milling machine or horizontal milling machine, are the original mechanical feed part of the abolition, the use of servo control feed. Mechanical work combined with the use of iron-plastic material, this material is characterized by wear-resistant, easy to reduce the friction in the feed, so that the machine running more smoothly. But pay attention to this kind of iron plastic material must use the lubrication system, or will soon be damaged. Need to change the ordinary T-shaped screw into a ball screw. This screw running smoothly, high precision, high demand for installation. Coupled with the servo motor, a simple and economical CNC vertical or CNC horizontal milling machine is completed.

There are many types of vertical milling machines: 1 vertical milling machine, 2 vertical bed milling, 3 vertical drilling and milling machine, 4 vertical turret milling machine, 5 vertical rocker milling machine.

This article will focus on vertical turret milling machines.

Vertical turret milling machine is the earliest name of the turret milling machine, mainly divided into No. 2 milling machine, milling machine No. 3, milling machine No. 4, milling machine No. 5, No. 6 milling machine. Its main structure is: bed, lift, slide, table.

The main feature of this vertical milling machine is the bed and the base is one. No. 2, No. 3 milling machine structure is the dovetail structure. No. 4 milling machine lift is a dovetail structure, its bed is a giant rail. No. 5, No. 6 above the milling machine lifts and beds are giant rails. This is the most important feature of the turret milling machine.

Milling head can be rotated 90 degrees left and right, front and back rotated 45 degrees. Milling head can be divided into section milling head and no section milling head, the maximum speed can reach 5400 r / min. This milling head processing high precision, and more for the abrasive manufacturing industry.

The belt drive system can be easily adjusted. The pulleys are made of aluminum alloy, which are subjected to dynamic balancing, so the stability of the rotation is very good.

Spindle teeth have been chrome-plated, the hardness is very high, to HRC60 or more, durable wear, greatly improving the service life. Milling head is generally divided into 3 horsepower and 5 horsepower. Materials are ordinary and standing steel. Standing steel milling head for the square, the speed is generally around 3600, but its rigidity, compared to ordinary milling head stability, cutting force. This milling machine automatic feeding system using more electronic feeders, stepless speed regulation, easy to use and easy maintenance. Turret milling machine sales are relatively large, and more for the manufacture and maintenance of abrasive and home use. In the extension arm can be installed on the plug, for the insertion of some keyway.

With the development of the market, there have been new vertical milling machine was developed, such as the development of vertical milling machine in 1999 ZX7550C, ZX7550W. These are all developed from simple vertical milling machines. Here I would like to introduce ZX7550 vertical milling machine.

Milling part is composed of gear transmission mechanism, there are 8 speed.

Drilling the largest diameter (mm): 50

End mill maximum width (mm): 100

Maximum tapping diameter (mm): M16

Spindle end to table distance (mm): 70-420

Spindle speed range: 110-1760

Spindle travel (mm): 120

Worktable size (mm): 800X240

Worktable travel (mm): 400X230

Dimensions (mm): 1290X1140X2100

Motor power (KW): 0.85 / 1.5

Net weight / gross weight N.W / G.W (KG): 610/770

The bed is a dovetail rail, the table is also a dovetail structure. No horizontal milling function, arm can move around before and after. In some places this milling machine is also known as a drilling and milling machine, because it can be drilled. Also known as rocker milling machine: because of its arm can swing. The automatic feed system uses a mechanical feeder for gear transmission. This compact size is very suitable for home use and tool maintenance. Then in 2000 developed the ZX7550W vertical milling machine, it is in the ZX7550C machine to increase the horizontal milling function, but this section is a belt drive.

The development of these two milling machines is a major breakthrough in the development of tool milling machines, laying a good foundation for the future development of vertical milling machines.
