What is the difference between CNC machining center and CNC CNC lathe?

1. What is the difference between CNC machining and CNC lathes?

Although CNC machining center and CNC lathe are both common CNC machine equipment, there is a big difference between the two.

From the layout point of view, although they are equipped with rare control systems, CNC machining is at least three-axis control, while CNC CNC lathes are two-axis control. There is a tool magazine in the middle of CNC machining, and a CNC lathe uses a tool holder. The functions of the two are relatively similar. They are both used to change the tool when machining the workpiece, but the detailed layout is different. The tool holder is an important part of the CNC lathe. It installs various cutting tools, and its layout simply affects the cutting performance and workability of the lathe. The tool holder is divided into turret type and row tool type. The classification of CNC machining intermediate tool magazines is more than that of CNC CNC lathe tool holders, such as disc type, bucket hat type, chain type, flying saucer type, synchronous type, etc. The tool capacity of most tool magazines is higher than that of CNC CNC lathe tools. The tool capacity of the rack is large.

Second, the difference between CNC machining center and CNC lathes in all aspects

From the point of view of processing limitations, the machining limitations of CNC machining centers are larger than those of CNC CNC lathes. CNC CNC lathes are mainly used to machine reverse parts. There are a lot of things that can be done in the middle of processing, such as boring, milling, cutting, reaming and ribbing, etc., and there are three-axis, four-axis, and five-axis CNC processing. For example, the VMC650 five-axis machining center of Taicheng CNC can process complex surfaces in the middle, which is an effect that CNC CNC lathes do not have.

1. Check the working conditions of the equipment

Confirm whether the external conditions in the middle of CNC machining are normal, including the following situations:

(1) Whether the emergency stop Is the state of depression;

(2) Whether the power cord is continuous and normal without damage; Turn on the intermediate peripheral equipment of CNC machining (such as air compressor) and then turn on the power from the main power supply to the machine tool once.

The operation process after power-on includes the following aspects:

(1) Release the emergency stop, and then use the handwheel to slowly move the CNC machining center to confirm that the machine tool can move normally in all directions;

(2) Roll the spindle normally to ensure that the spindle can rotate;

(3) Execute the tool change action to ensure the normal tool change in the tool magazine;

(4) Execute The four-axis clamping is easy to ensure that the four-axis can be clamped easily and normally;

4. Execute a simple copying program to hold the heat engine

5. Hold the workpiece clamping

Clean the work surface or fixture before clamping the workpiece , Even if the workpiece is not bumped against the table when loading, confirm the stability of the clamping after clamping.

6. The following points need to be paid attention to when installing the tool

(1) Clean the selected tool to ensure that there is no oil and impurities on the tool;

(2) Clean the tool holder to ensure that there is no oily impurities on the tool holder, especially the chuck and taper hole;

(3) Clean the spindle to avoid scratches when cleaning the spindle taper hole The taper hole of the spindle is damaged;

(4) Install the tool on the tool shank to ensure that the installation is firm;

(5) Install the tool shank on the spindle, and measure the spindle runout with a meter Whether it meets the application requirements;

(6) Change the tool to the tool magazine at one time.

Import processing program for processing

If it is an application program, a simulation processing should be performed to ensure that the program is correct.

Replacement of workpieces When replacing workpieces, pay attention to cleaning the work surface and the contact surface of the workpiece.

Clean the machine tool after the machining work

Clean up the machining waste, clean the bed, spindle, tool magazine, tool holder.

Emergency stop and power off when the machine tool returns to zero.

Turn off the power supply of peripheral equipment in the middle of CNC machining, and exclude the sanitation in the middle of machining.
