The Purpose of Slitting Machines
Most of the time, these rolls of material need to be slit in order to make them usable for making other things. The companies that manufacture this semi-raw material have to do some kind of slitting. Most companies go for contract slitting. They hire another company which has big OEM slitting machines to do the job. The reason for this is that these machines are a huge investment that needs maintenance and operation by trained professionals who know how to deal with the equipment.
A slitting machine includes a pair of parallel arbors structured to support a plurality of cutting knives. The arbors are mounted to a head stock and tail stock on the slitting machine. The head stock and tail stock each rotatably support eccentrics which support the end portions of the arbors. Angular contact bearings, such as tapered roller bearings or ball bearings with inclined races, are positioned between the head stock and tail stock and the respective eccentrics and also within the eccentrics between the arbors and the eccentrics.
Mechanisms are provided for providing an axial load across all of these bearings to eliminate play and so to accurately position the arbors so that cutting accuracy can be maintained. One such mechanism is a collet/piston supporting the operator's end of the arbors. The collet piston is received in a cylinder to which hydraulic pressure can be applied through a rotary coupling. When pressurized, the collet piston is forced onto a tapered end of the arbor, accurately positioning the arbor. At the same time, because the cylinder is mounted to the inclined bearings within the eccentric, the reaction force is transmitted through the angular contact bearings to the machine frame, precisely locating the arbors centrally of the bearings in which they are mounted. The collet piston may be made double acting so that it can assist in removing the arbor from the collet/piston. This permits self locking tapers to be used.
The first issue that companies face if they perform slitting themselves includes the basic size of the slitting equipment. These are large-scale heavy duty machinery so they need a wide open, isolated space not just to be kept but also to operate in. In addition, machines also require specific voltage settings. The machinery has to be operated by people who have had proper training and know what do to in case something malfunctions. Due to all these reasons companies find it more convenient, in terms of time and money, to hire a contracting company carry out their slitting needs.
Machines which slit material basically take huge rolls of film or cloth and cut them into required sizes very efficiently. There is a variety of slitting machines out there that vary according to what purpose they are required for. These will have different types of cutter blades in them for specific materials. For example the same cutter blade cannot be used for sheets of metal and also for carpet cutting. The size of the machine also has to be appropriate enough. In addition, some of these come with adjustable blade sizes and these are most convenient for slitting many kinds of materials.
Slitting apparatus are sold and bought throughout the world. Some are also available for sale online and they are described there with their functionalities and warranties. There are even second hand slitting apparatus for sale and these usually attract buyers since they come at a more reasonable price and often serve the same purpose as a new one would. These are good for new companies in the business. These new companies can start with smaller slitting gear and trying out on a few contracts.
Machines performing slitting help bring the semi-raw material into a form that can be used to make many things. These machines also sell for a high price since they are something that will always be in high in demand. Companies which specialize in slitting usually have all sorts of machinery at their warehouses along with trained professional operators. Thus they can serve the needs of slitting for a company. Slitting jobs are required by every manufacturer in all parts of the world and thus it is a flourishing business everywhere.
