The working efficiency of the machining center is very high, and the preparation work before the start of construction is essential. Friends who operate the machining center every day may not know a standard and complete set of preparations for the start-up of the machining center. In fact, the quality assurance of CNC machining in CNC machining centers is inseparable from prior preparations. For the old master, the rich processing experience and the knowledge of the mold are firmly grasped in the processing details.

What is the process of a complete CNC machining center?

First, you should read the part drawings and the production program list, transfer the written CNC program to the machining center, and check the program code and cutting parameters. In terms of the workpiece, the processing size and allowance of the process should be established and the workpiece should be properly clamped, and the processing coordinates should be accurately aligned. The tool should be properly clamped and appropriate cutting parameters should be selected. Observe and record the trial cutting process, and adjust the cutting parameter data in time. Make sure there is no problem in the trial cutting process and start production.

What are the details to pay attention to before processing?

Before starting the machine operation, check whether the workpiece reference position is consistent with the drawing position after receiving the program sheet. Confirm whether the requirements of the program and the drawing are consistent. If there is any problem, it must be solved and discussed with the programmer and production staff. Do not start processing when in doubt.

According to the material and size of the workpiece, it is judged that the programmer should select a reasonable tool for roughing or smooth cutting. If the tool application of the CNC machining center is found to be unreasonable, the programmer should be notified immediately to make corresponding changes in order to improve the processing efficiency and workpiece processing accuracy.

When clamping the workpiece, pay attention to the position of the fixing parts and the extension length of the nut bolts on the pressure plate. In addition, when locking the angle fixing parts, the screws should not be on the top and bottom.

Before the cutter head is installed on the machine, the taper matching position should be wiped clean with a cleaning cloth, and the corresponding position of the machine tool sleeve is also cleaned, so as to avoid iron filings on the mating surface affecting the accuracy and damaging the CNC machining center.

The most important CNC machining is the first tool, because if you operate and check carefully, you can know whether the tool length compensation, tool radius compensation, program, speed, etc. are wrong, so as to avoid damage to the workpiece, tool and machining center.

A qualified CNC machining is inseparable from timely communication with colleagues who perform their duties and grasping the key points at the end of the thin end. Only in this way can the performance of the CNC machining center be more accurately exerted. In order to better realize CNC machining.

Installation environment

After the CNC machining center arrives at the factory, it is necessary to make a foundation that meets the requirements according to the foundation map, which is enough to support the levelness and firmness of the machine tool. The thickness of reinforced concrete is about 50cm. For hoisting, in addition to preparing enough load-bearing forklifts in advance, there should also be special spreaders or wire ropes with sufficient strength.

The indoor temperature will have a certain impact on the machining accuracy of the CNC machining center. If it is a relatively precise workpiece processing, it is necessary to manage the room temperature to achieve the most ideal processing accuracy. The ambient temperature is generally between 10°-40° and the humidity is 75%. When the machining accuracy is required to be between 0-10um, it is recommended that the temperature range be controlled at 23°.
