Compared with the horizontal milling machine, the main difference between the vertical milling machine and the horizontal milling machine is the vertical arrangement of the spindle, which is widely used in various fields of the CNC machine tool industry! Because the vertical milling machine is suitable for machining large planes and using various milling cutters with handles to process grooves and step planes, what are the purchasing elements of the vertical milling machine?

Purchasing Elements of precision vertical milling machine

 1.From the aspect of workpiece machining accuracy requirements.

The vertical milling machine is selected according to the accuracy requirements of the workpiece to be machined. At the first stage, China has drawn up the accuracy specifications for vertical milling machines. Among them, there are professional specifications for vertical milling machines with vertical lifting tables. The positioning accuracy of the linear motion coordinates of the standardized vertical milling machines is 0.04/300mm, the repeated positioning accuracy is 0.025mm, and the milling accuracy is 0.035mm. The factory precision of the vertical milling machine has a certain storage, which is about 20mm less than the national standard tolerance. Therefore, from the aspect of workpiece precision, the general vertical milling machine can meet the processing requirements of most parts. For the workpiece with high precision requirements, the precision CNC vertical milling machine should be fully selected.

 2.Consider from the aspect of workpiece processing scale.

First, select according to the size of the workpiece to be machined. For example, for the contour milling task with disordered machining basis for small and medium-sized workpieces, the vertical milling machine with smaller lifting table can be used, and the width of its worktable is less than 400mm. However, for gantry vertical milling machines with large-scale and disordered parts, the width of their worktable is generally controlled at 500-600mm.

3.Considering the characteristics of batch processing of workpieces.

The selection of special vertical milling machine for mass purchase. If it is a small batch and requires high efficiency, it is very suitable to use CNC vertical milling machine. Because there are many reserved workpieces, fixtures and programs that can be stored and reused.

4.Considering the characteristics of workpiece processing.

Workpiece processing features vertical milling machine selection. Vertical milling machine equipment with point and line system is selected for machining parts of frame plane and unequal height steps. In addition, according to the requirements of part processing, on the basis of the general vertical milling machine, the dividing head and reverse operation table can be added, and the spiral groove and blade parts can be processed.

The operation notes of precision vertical milling machine are as follows

1.before using the vertical milling machine, it must be carefully checked according to the patrol inspection points and lubricated according to the lubrication chart.

2.if the vertical milling machine is stopped for more than eight hours and then the equipment is started, it shall be rotated at a low speed for three to five minutes first, and then the operation can be started after confirming that the lubrication system is smooth and all parts move normally.

3.during the use of the milling machine, it is not allowed to leave or entrust others to take care of it. It is not allowed to remove the safety protection device and the gear iron.

4.when maintaining the vertical milling machine, loosen the fastening screws of the beam spindle workbench and the lifting table before moving, remove the surrounding sundries, and then wipe the guide rail and apply oil.

5.during rapid or automatic feeding of the milling machine, the range stop iron shall be adjusted first.

6.the operation and lubrication of equipment and all parts must be checked frequently during work. In case of poor operation or lubrication, stop using.

7.it is forbidden to leave work, clamp measuring tools and workpieces on the worktable.

8.when adjusting the automatic cycle, the correctness of the automatic cycle of the machine tool must be checked before starting.

9.after the work is completed, place the handles of the vertical milling machine in the non working position, place the worktable in the middle position, drop the lifting table below and cut off the power supply.

10.it is forbidden for the operator to overload the vertical milling machine.

Make a purchase of cnc vertical milling machine suppliers from China, you can get them at a good price if you have a large quantity. We hope to be your long-term partner.
