CNC used in the field of machining industry machining center There are many kinds of Developed on the basis of milling machine, it is called numerical control Gantry milling machine Machining center, referred to as numerical control Gantry machining center Gantry machining center It is one of the most widely used CNC machine tools with the highest output in the world

numerical control Gantry machining center Of The main features are as follows:

one )On the basis of numerical control boring machine or numerical control energy machine, a tool changing device is added to make the workpiece in one - After the second clamping, the surface of the workpiece can be processed continuously, and the process is highly concentrated.

two )Generally, it is equipped with an automatic indexing rotary table or spindle box, which can automatically rotate the angle, so that the workpiece can automatically complete the multi process processing of multiple plane or multi angle positions after one clamping.

three )The machining center can automatically change the spindle speed, feed rate and tool relative to the workpiece trajectory and other auxiliary

Function.

four )If the machining center is equipped with an exchange worktable, the workpieces are processed on the worktable at the working position, and the other workpieces are loaded and unloaded on the worktable at the loading and unloading position, which does not affect the normal processing of workpieces.

The above is a few common characteristics of Longmen CNC machining center, taking this opportunity, Fu Haihe small series from CNC gantry( one )The use of equipment to implement the fixed person fixed mechanism, requiring the operator to operate the equipment with the operating certificate. When large-scale equipment is operated by many people, special personnel must be assigned for command.

two )The operator should be familiar with the main technical performance, structure, maintenance content and intact standard of the equipment used.

three )Preparation before work:

a . check the transmission system, operating system, lubrication system, pneumatic system, starting position of various switches, safety braking protection device, power voltage stabilizing system and electrical indication of the equipment. The above systems shall be complete, correct, sensitive, reliable and in good condition. The connecting parts and the surrounding parts shall not be loose.

b According to the equipment lubrication chart.

c Test run the spindle and servo shafts at low speed manually.

Starting from the characteristics of the machining center, we will introduce the operating procedures in detail.

d According to the part processing program sheet, check whether the tool compensation value and the offset position of the key points in the memory table of the numerical control system are wrong. Call out the tool compensation value and zero offset value to check whether they are correct.

e When inputting with paper tape, always check whether the paper tape is damaged and whether the photoelectric reader is normal.

f The use of tightening parts T The specification of T-bolt should be the same as that of equipment workbench T The groove specifications are consistent. The force should be moderate when tightening. It is forbidden to apply force to correct parts at all parts of the equipment.

g Check whether it is complied with Operation manual of machine tool The precautions specified in. (4) After connecting the power supply, there are no pre work inspection items:

Press NC Device power start key “ON” , in CRT The initial position coordinates of the machine tool will appear on the display. Check the total pressure gauge installed on the upper part of the machine tool, if the meter reading is “4MPa” It indicates that the system pressure is normal and can be operated formally.

five )The correct operation steps are as follows:

a Reasonable use and correct operation according to the equipment manual. It is forbidden to use overload, performance and specification.

b When the first part is programmed for trial processing, the operator should cooperate closely with the programmer, and the formal processing can be carried out after confirming that the program is correct.

c When installing the clamping tool, clean the handle and the spindle taper hole and positioning.

d The workpieces and cutting tools must be installed firmly. Prevent collision with machine tool when loading and unloading workpiece. Heavy parts and fixtures shall be loaded and unloaded by crane or assisted by others.

e In the process of processing, the operator shall not leave the post without permission or be entrusted with custody, and shall not do anything irrelevant to the work. You can press suspend Button. It should be used correctly Emergency stop switch It is strictly forbidden to switch off the power supply at will.

f It is forbidden to place tool cards, measuring tools, stacking parts and irrelevant articles on the equipment guide rail surface and working table. It is forbidden to step on the protective cover in the rain and step on the working table with shoes with metal nails.

g Pay attention to the abnormal phenomenon during the operation of the equipment, stop the machine in time in case of failure, take measures, and record and display the fault contents. In case of an accident, it is necessary to stop the power supply immediately, protect the scene, report in time, and cooperate with the competent department in the analysis and investigation.

six )Maintenance after work.

a Operators should timely clean up the debris on the equipment, clean up the work site and do a good job of maintenance.

b After the maintenance of the equipment, the operator shall move the relevant handle and parts of the equipment to the original position. All worktables shall be oiled for protection, and the power supply shall be cut off according to the specified sequence.

c Exchange and record the shift according to the regulations.

Because the machining center has the above functions and strict operating procedures, the time of workpiece clamping and measuring and the high-speed adjustment of machine tool and the turnover, handling and storage time of workpiece are greatly reduced, so that the cutting time utilization rate of machine tool is higher than that of ordinary machine tool 3-4 In this way, the productivity is improved, especially when the workpieces with complex shape, high precision requirements and complicated variety replacement period are processed.
