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.
