A proper programming is vital to the proper functioning of any machine, and of course of a CNC controlled punching machine. Programming directly affects the productivity of the machine as well as the life of its components and tools, so with better programming the punching machine will become more productive at lower cost.
In order to make proper programming of a punching machine is necessary to follow some guidelines and criteria, and at the same time to avoid some practices that may cause operating problems. Some of these practices are the following:
Use the largest possible tools: if we use large tools with the idea of reducing the amount of punches and so try to minimize punching time, we may make the mistake that those tools do not work correctly, which will cause premature tool wear and this misuse will generate problems.
Large size micro-fastenings on the sides of the part: using larger micro-fastenings with the intention of reducing the number of micro-fastenings is wrong. It is more interesting to place more and smaller micro-fastenings, which facilitate the separation and removal of the parts .
Loose scraps: it is very important to avoid loose scraps on the table, since if any of these remnants is placed just at the punching point, the thickness will be double and then the gap will not be accurate.
The birth of the first laser dates back to 1960, and in little more than 50 years, the evolution of the laser in the industry has been very quick, so much that its use in some processes is already widely consolidated, as in the case of sheet metal cutting. The application of sheet metal laser cutting solves manufacturing problems of complicated parts that could not be performed otherwise.
Laser technology is a field that offers endless possibilities, whose full potential has not been discovered yet, even through the important developments made recently, as it is the appearance of the fiber laser, whose main advantages were explained in a previous post.
Correct programming of a punching machine affects directly the life of its punching tools. The number of punches a tool can make in a punching machine is closely related to the programming of the same. Poor programming can greatly reduce the life of the punching tools.
When making a program, you must take into account that the tool should work at least to 2/3 of his section, in order to avoid as much as possible the decompensation of the punch, and prolong considerable the life of the tool.
In the event that alternate punches must be programmed, which are mainly used for thick sheet metal punching, machining of the slots must be performed in two operatons, so one in every two punches is left undone. This results in centred and balanced punches, so that the force used on either side is the same, which avoids tool wear.
Following these helpful tips, the life of the tooling of your punching machine will be extended, with the consequent economic saving this entails. In DANOBAT we can supply all kind of punching tools, in addition to solve all your doubts in this regard.
The sheet metal division of DANOBAT, as manufacturer of fiber laser cutting machines, offers different solutions to perform automatically the sheet metal loading in its machines.
The simplest option is the fit a rotating arm with a suction-pads grid, to feed the machine. In this case, the cut part unloading is performed manually by the operator.
This same system can be optimized by adding to this grid a comb system to unload the blanks automatically.
This is a flexible and economic solution but it requires quite a lot of space, since it requires the installation of two automation posts, one to carry out the loading of blanks and one for the unloading of the finished formats.
In case the customer does not have much space, the best solution is a compact system for automatic loading and unloading of blanks. This system consists of two transverse posts upwards, over laser cutting machine standard feeding position, just taking up a little more than the space occupied by the same laser cutting machine. The system consists of a suction-pads grid integrated into the structure for the sheet loading and a set of combs for the parts unloading.
DANOBAT is specialized in the manufacturing of customer adapted solutions, but has also demonstrated during its 50 years of experience, a great capacity in the design and creation of basic punching machines, whose strong points are the strenght and efficiency, as it is the case of CHROMA punching machine.
CHROMA is the star in our punching machine range. The high productivity and precision levels it reaches make it the ideal solution to cover the most demanding production requirements. Equipped with a 30 Tn servo-electric motor achieves very high punching rates. It is offered in two sizes depending on the axis travel: CHROMA 30 and CHROMA 40. A greater working area translates into better use of material.
CHROMA punching machine of DANOBAT has been ergonomically designed, providing benefits at both operational and maintenance levels.
Among the most noteworthy benefits we must highlight the EASY TURRET system by DANOBAT, which improves access and reduces tool change time. Furthermore, each tool in the multi-tool becomes indexable.
The application of ergonomy in machine design has also meant a great advance in maintenance thanks to the incorporation of numerous mobile elements and improvement of the access to the key points.
On the occasion of the next installation in China by the Sheet Metal Division of DANOBAT of two lines for sheet metal processing, we have received in our premises the technician of DANOBATGROUP China for two weeks. This technician will be responsible for technical support of these machines.
DANOBATGROUP makes available technical assistance service in China, and the local technician Mr. Zhang Haifeng has had the opportunity to deepen his knowledge on punching, shearing and bending, with two weeks of intensive training.
The installation of these two machines with significant added value, the Punch + Shear combination machine model CUPRA, and an automatic Panel Bender, model PG2600, is a boost to the effort that DANOBATGROUP is making in China. At the same time it confirms the commitment of this Asian country to invest in machines of the highest quality and specialization.
