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.

In the next article, I will introduce the turret milling machine.
