Interview with Ion Garmendia, commercial director of Danobat S. Coop. -Division saws

The guipuzcoana Danobat Sierras of tape, the Danobat group, has extensive experience in the manufacture of saws for cutting and drilling facilities. Knowledge of trends and the evolution of market, habits of consumption, new technologies and the objectives of this unique industrial segment, Ion Garmendia, commercial director of Danobat S. Coop. -Division mountain ranges of tape and drilling units, us about up to the reality of this industry

The sawing through sierra tape, is to cut almost any type of material, by means of a sheet of tape or sierra, which is placed on a scrollable, usually being the material set by Jaws head. There are different types of court, which are basically classified in horizontal, vertical saws and cutting angle, thus covering the possibility of cutting almost any geometry of matter.

In reference to mountains or court for cutting of metal sheets, a great variety of possibilities, but the most used are those of bimetallic type, in grades of M.42, and M.51 strap, and then there are those of hard metal or carbide, in which case there are different degrees or types, intended for different applications depending on the quality of material to be cut (carbon, stainless steels, steels for tools, aluminium, etc.), and types of materials to be cut (massifs, tubes, etc.).

There are also leaves with teeth of diamond, etc., for cutting materials such as glass, tires, steels with large temple etc., generally used in very special operations.

The leaves or blades are manufactured in a variety of toothed, from a passage of 14/18 teeth per inch, to be able to cut thicknesses of thin materials, up 0.7/1 toothed tooth per inch for diameters up to 2500 mm. cutting

The dimensions of the strips used in the industry, are between 27 x 0, 9 mm and 80 x 1, 6 mm thick.

Finally, to say that the leaves of both tape bimetallic as carbide, they can have with treatments such as e.g. Titanium Nitride bath, offering the possibility of faster, cut with a higher tool life. These treatments are proving a major revolution in the area of the Court in many applications, which require a great production.

Today business leaders are aimed at high production in its different work shifts, so machines capable of providing coverage to the demands of production, working as autonomous cells are required. This is why so are currently installed trim lines; This means that in addition to the cutting machine, are offered cutting with lungs of food stores, lungs of storage of remains of bar, and collection systems of cut pieces, forming a line with these add-ons. These lines, must provide a simple for the operator management system, as in this sector users do not usually have a technical training in CNC, the management and programming of the lines should be as simple as possible for the effective performance of the work.

In addition to the above, there is a growing demand for the factor of the operator has the minimum impact on the production obtained in the different shifts, so in this type of machines, the operator in addition to loading the materialsimply indicates the dimension of the piece, its geometry, length of parts to obtain and number of units, and is the CNC of the machine which is responsible for the rest of the management of court, with criteria previously factory markings. The aim is that equal work different shifts, get virtually the same productions.

In order to achieve this degree of autonomy and degree of constancy of production, currently you are using systems of measurement, guidance, control, etc., similar to machines tools more sophisticated, so that in its day was called simply as sierratoday is a machine-tool of court.

As an example, can point out that currently the required degree of sophistication leads us to employ rectified spindles to execute the movement and control of court, rather than more classics such as cylinders, etc. systems

In my opinion, I think that to cut well, does lack a rigid machine, since the tool is a simple strap without much rigidity, and also have a precise and stable system of cutting and measurement.

I really think that there are not many secrets, but in addition to having a complete team, qualified and motivated people who perform their work in different jobs, us at Danobat we are proud of having the technological centre "ideko", within the Danobat group, where we have a media, organization, system of work, based on a study of the sector, competitors, value, AMFE, workshop of prototyping, analysis system mechanical engineering (static, dynamic and thermal calculations), engineering control, etc., where the synergies produced in the manufacture of various machine tools take advantagewith good and above all, involving the entire team, working as joint.

All this, is to obtain a product of quality, rigidity and accuracy, which is equal to the demand of customers, easy to use, with few incidents, and in which case it is practical for the work of SAT.

For some years I think not, since we are in the vanguard as regards technology Court, range of solutions and price. With these advantages we can very well defend our peninsular. Also given the situation that a very high percentage of our products is aimed at major countries in the production of mountain ranges such as Germany, and Italy.

In Spain are two manufacturers of blades, and there are also many distributors (not manufacturers) of machine tools which include among other machines also sierras, but which are generally more focused on small, normally tronzadoras tape machines. They sell more them as complement, but without being dedicated specifically to give a solution in the Court, as we can be us, that in addition to the most complete range of solutions we offer our knowledge of materials, sheets of tape, extensive practice of the Court, peripherals, specialized technical service, provision of spare parts, etc.

As mentioned earlier the issue of the ecological Court, is in dry, without lubricant, is studying for certain applications.

It seems to me that in the case of large wholesalers, forges, steelworks, etc., court programmes will be carried out in the Office, passing through network programs to machine for execution based on their product code, in which case each material will have their court specificationssuch as speed, step, etc. There will be a collection of production times, together with the system, stock control, control of the incidences, etc.

I think that every time we went to a degree of sophistication in machines, in order to use less machines, and thereby smaller space used, fewer personnel, greater and better control of inventories, costs, etc., which nowIt is requiring that previously already have mentioned, more court centres.

Above all our security regulations, which determine the machines, but rather at European level. To this we should add that very strict standards for fluids, oils, etc., there are and also legislation within the EC, on the basis of languages controls, books of instruction, information boards, etc.

In response to the demand of the estructuristas sector, we have developed an innovative system of cutting by plasma 3D, based on the program "dantatech" which in addition to the Court of common materials in the metallic construction, allows the cutting of round and square pipesto respond to the increasing demand for these materials in the construction, and also allows making any form of court through the incorporation of a generator of trajectories of type CAM, so that the operator matter the level of the piece with the Court to carry out, and the machine automatically generates the necessary path to realize the Court, without the need to be limited to predefined macros ranges through forms.

For this same sector, we have developed lines of court and very flexible drill, which can be customized depending on the needs of each client. Thus, in recent years, we have mainly developed three types of automatic drill, that we could classify them in the drill head type turret with four tools for machining, the drilling of three independent heads, with or without automatic tools changer, and the bore of a head with longitudinal movement throughout the piece to work.

All of them are controlled by CNC Software Danmach, compatible with files DSTV.

""In addition, we have developed the new Center Court ASU-ASR with 6 seasons of load and store collection of remains of materials commanded through a system of programming of automatic cutting parameters,"Danocut" for different materials on the store.

Finally, include the range of hills CP-TV "Trolley" which falls within the solutions offered by Danobat to the prooblemática of cutting and handling of heavy materials. The particularity of this type of sierras lies in its mobile table or trolley, and its operating mode, which allows a significant savings of time for the material handling. The loading is performed in an external position without own head of an obstacle to this. In addition, the cut pieces may remain on the table, without having to be withdrawn once cutting is performed. Once all tracks have been made, the trolley back on the Rails, so that the cut pieces can be easily downloaded from a comfortable position.
