Dacu Laser factory has 2 sets of Gantry Milling Machines from Neway(US Company) which gives us high-quality manufacturing process and high-quality laser machine.
Speaking of the portal milling machine, dacu laser has been introducing some operating procedures for the milling machine. The various safety operating procedures are basically mastered, but everyone has overlooked one of the most fundamental problems is the characteristics of the gantry milling machine. Do not understand the advantages, just say that skilled operation is really a professional? Real professionals should be professional talents for their performance and operational skills. Since everyone has mastered the operation, today, dacu laser will take everyone to change their thinking. Let’s take a closer look at the advantages of Longmen. What?
1. Good processing adaptability
When the processing object of the gantry milling machine is changed, it is only necessary to re-program the new program to meet the processing requirements of the processing object, and the processing transformation can be realized quickly. This provides great convenience for the production of single-piece small batch parts of complex structures and the trial production of new products. In addition, portal milling machines can often perform sophisticated and complex parts that are difficult or impossible to machine on conventional machines, such as complex curves, curved parts, and variable lead threads.
2. Conducive to the modernization of production management
The gantry milling machine can accurately calculate the part processing time, and effectively simplify the management of the inspection fixtures and semi-finished products, which is conducive to the modernization of production management. The gantry milling machine uses digital information for computer networking and becomes the basis for integrated integration of computer-aided design, manufacturing, and management.
3. High processing productivity
The time required for part machining includes maneuver time and auxiliary time. The portal milling machine can effectively reduce the time of these two parts, thus improving the processing efficiency.
The spindle speed and feed rate range of the gantry milling machine is much larger than that of the ordinary machine tool. Therefore, the most favorable cutting amount can be used for each process and step, and the potential of the process system can be fully utilized. The gantry milling machine has good structural rigidity, allowing for a large amount of powerful cutting, which effectively saves maneuver time. The moving parts of the gantry milling machine have a fast moving speed, and the time spent on the auxiliary movements such as the leading, retracting and positioning is much less than that of the ordinary machine.
In mass production, the portal milling machine requires almost no re-adjustment of the machine when replacing the machined parts, and the installation time is short. The gantry milling machine can be operated according to the coordinates to eliminate auxiliary processes such as scribing and reduce auxiliary working hours. The processing precision of the gantry milling machine is relatively stable. Generally, only the first piece inspection or the sampling of the critical dimensions between the processes is performed, which can reduce the downtime inspection time. Therefore, the utilization of portal milling machines is much higher than that of ordinary machine tools.
In the multi-process machining center with automatic tool change and multi-spindle and automatic feeding device, it can realize multi-process continuous processing, shorten the logistics process, reduce the semi-finished product turnover time, and further improve the production efficiency.
4. High processing accuracy
The gantry milling machine is processed according to the instructions given in digital form. The pulse equivalent given by the numerical control device (the amount of movement corresponding to the moving part of the gantry milling machine per pulse output) is generally 0.001 mm, and the feed chain is reversed. The inter-division and the screw pitch error can be compensated by the numerical control device, so the gantry milling machine can achieve relatively high precision, such as positioning accuracy of 0.002 ~ 0. 005 mm. In addition, the transmission system and machine tool structure of the portal milling machine generally have high rigidity and thermal stability, and the manufacturing precision is high. The automatic machining method of the gantry milling machine can avoid the error caused by the operator’s human factors, and therefore, the same batch of parts is processed. The dimensionality is good, the precision is high, and the processing quality is very stable. For the contour machining of complex parts, the portal milling machine can control the infeed path and the feed speed to avoid local defects on the machined surface, thus achieving higher precision and surface quality.
5. Good economic benefits
Although the gantry milling machine costs a lot of equipment for each part, but in the case of single-piece small batch production, the use of CNC machining can save the slashing man-hours, reduce the adjustment processing and inspection time, and directly save production costs. The cost of CNC machining tooling is also relatively low, and the CNC machining quality is the most stable, which can reduce or even avoid the generation of waste products, and reduce the production cost. The gantry milling machine has strong versatility and low investment risk. The gantry milling machine has a wide range of processes, which facilitates process concentration, streamlines logistics and reduces management costs. The gantry milling machine can process high-value-added complex high-precision parts for high output. Therefore, the use of gantry milling machines can achieve good economic benefits.
6. Low labor intensity
The machining parts of the gantry milling machine are automatically carried out according to the pre-programmed procedures. The operator usually does not need heavy manual work, except for the operation panel, loading and unloading the workpiece, intermediate measurement of key processes and observing the operation of the machine tool. The degree is greatly reduced. Production type gantry milling machines generally have better safety protection and the working conditions of the operators such as automatic chip removal, automatic cooling and automatic lubrication are also improved accordingly.
