So What Is A CNC Machining Center ?

Machining centers are developed from CNC milling machines. The biggest difference from the CNC milling machine is that the machining center has the ability to automatically exchange machining tools. By installing different-purpose tools on the tool magazine, the machining tool on the spindle can be changed through an automatic tool changer in one clamping to achieve a variety of machining Function. CNC machining center is a high-efficiency automatic machine tool suitable for processing complex parts composed of mechanical equipment and numerical control system. CNC machining centers are among the most productive and widely used CNC machine tools in the world. Its comprehensive processing ability is strong, and the workpiece can complete more processing content after one clamping, and the processing accuracy is high.

For batch workpieces with medium processing difficulty, its efficiency is 5 to 10 times that of ordinary equipment, especially it can complete The processing that cannot be completed by ordinary equipment is more suitable for single-piece processing with complex shapes and high precision requirements or small and medium-sized batches of multiple varieties. CNC machining center is a kind of CNC machining machine tool with relatively complete functions. It concentrates the functions of milling, boring, drilling, tapping and thread cutting on one device, so that it has a variety of processing procedures and technological means.

Machining centers can be divided into vertical, horizontal and composite machining centers from the appearance. The main shaft of the vertical machining center is perpendicular to the worktable, which is mainly suitable for processing plate and shell workpieces, and can also be used for mold processing. The axis of the main shaft of the horizontal machining center is parallel to the worktable. Most of its worktables are CNC rotary tables controlled by servo motors. In one clamping of the workpiece, the rotation of the worktable can realize the processing of multiple processing surfaces. It is suitable for Box type workpiece processing.

The compound machining center mainly refers to a machining center with two vertical and horizontal spindles or the spindle can change the angle by 90°, so that five surfaces can be processed in one clamping of the workpiece. There are special classifications by function: single worktable, double workbench and multi-workbench machining centers. Single-axis, double-axis, three-axis and machining centers with interchangeable headstocks. According to the classification of guide rails, there are: line rail machining centers, hard rail machining centers, etc.

CNC Machining Center

Deli CNC is the best CNC milling machine center focusing on three-axis, four-axis and five-axis vertical compound single worktable. In this type of machine, multiple jobs can be done in one setup. Most vertical machining centers have three axes, and some feature a spindle head that can rotate in one or two axes. When it comes to machining engraved surfaces, vertical machining centers are best suited for the mold and die making industry. The main types of vertical machining centers are as follows: traveling column, gantry structure and multi-spindle. The vertical machining center is easy to install, easy to operate, easy to observe the processing situation, easy to debug the program, and widely used. However, limited by the height of the column and the tool changer, parts that are too high cannot be processed. When processing a cavity or a concave surface, the chips are not easy to discharge. In severe cases, the tool will be damaged and the processed surface will be damaged, which will affect the smooth progress of processing.

Gantry CNC Milling Machine

The machining center is equipped with a tool magazine, which stores different quantities of various tools or inspection tools, which are automatically selected and replaced by the program during the machining process. This is the main difference between it and CNC milling machines and CNC boring machines. Especially for workpieces that must use tooling and special equipment to ensure product quality and efficiency. This will save a lot of time and cost for the development and modification of new products, so that the enterprise has strong competitiveness.

Adding a machine protective cover ensures the safety of the operator and the sanitation of the environment. With the fast synchronous tool change magazine, the tool can be prepared in advance, and the tool change time only takes 2 seconds. The whole machine is cast and formed, which is suitable for high-precision processing and has strong stability. According to the machining accuracy: there are ordinary machining centers and high-precision machining centers. For ordinary machining centers, the resolution is 1μm, the maximum feed speed is 15-25m/min, and the positioning accuracy is about 10μm. High-precision machining center with a resolution of 0.1μm, a maximum feed speed of 15-100m/min, and a positioning accuracy of about 2μm. The ones between 2 and 10 μm, with more than ±5 μm, can be called precision level.

HCK LARGE SPAN GANTRY HIGH SPEED MACHINING CENTER

Features of CNC machining center: It can realize the linkage control of three or more axes to ensure that the tool can process complex surfaces. In addition to linear interpolation and arc interpolation functions, the machining center also has various processing canned cycles, automatic tool radius compensation, tool length automatic compensation, graphic display of the machining process, man-machine dialogue, automatic fault diagnosis, off-line programming and other functions.

CNC Machining Has The Following Advantages :

①The number of tooling is greatly reduced, and complex tooling is not required for processing parts with complex shapes. If you want to change the shape and size of the part, you only need to modify the part processing program, which is suitable for new product development and modification.

②The processing quality is stable, the processing precision is high, and the repetition accuracy is high, which is suitable for the processing requirements of aircraft.

③In the case of multi-variety and small-batch production, the production efficiency is high, which can reduce the time for production preparation, machine tool adjustment and process inspection, and the cutting time is reduced due to the use of the optimal cutting amount.

④ It can process complex profiles that are difficult to process by conventional methods, and even process some unobservable processing parts.

Imported high-precision ball screw, guide rail, rack and pinion are used to ensure the stability of the machine tool. High-speed, high-torque, and large-diameter spindles ensure high-precision machining. The gantry-type double-drive movement is equipped with a multi-station capacity tool magazine to ensure high-efficiency processing of the equipment.

Disadvantages of CNC machining: machine tool equipment is expensive, and maintenance personnel are required to have a high level.

Troubleshooting of CNC Machining

①: CNC machining center serial encoder communication error alarm, reason: the unit detects that the motor encoder of the CNC machining center is disconnected or has poor communication. Check whether the encoder feedback wire of the motor and the amplifier are connected correctly and firmly. If the feedback line is normal, replace the servo motor (because the encoder of the motor is integrated with the motor and cannot be disassembled), if it is an α motor, replace the encoder. If it occurs occasionally, it may be caused by interference. Check whether the shielding wire of the motor feedback line is intact.

②: CNC machining center encoder pulse count error alarm (LED display 6, system PMM screen displays 303/304/305/308 alarm) Cause analysis: The serial encoder of the servo motor loses pulses during operation, or does not count. Turn it off and on again, if the same alarm persists, replace the motor (if it is an α motor, replace the encoder) or the feedback cable. If the alarm disappears after the CNC machining center is restarted, it must return to the reference point before running other commands. If the PMM of the system is 308 alarm, it may be caused by interference, turn off and on again.
