DCBS SERIES BANDSAWS FEATURES METAL CUTTING WITH BANDSAWS Band saws are a cost effective way of cutting a wide variety of materials in many different shapes. They are especially useful for exotic and hard alloys. Solids or profiles can be cut in bundles or singularly with either manual or automatic feeds. As band saws are fast and inexpensive, they are used commonly in steel plants, craft, aircraft, automotive industries, manufacturing, construction and aluminum sectors. Below are some samples of shapes that are commonly cut on band saws. LOW SOUND LEVELS HYDRAULIC & ELECTRIC SYSTEMS Sounds in production process are caused by the mechanical parts. The sounds due to vibration are minimized when the pulleys and the bearings are in appropriate length and quality. In Durma series bandsaws, the pulleys and the direction arms are produced by vibration and soundabsorbent casting. Bearings from worldwide best quality brands are used. The desired precision in hydraulic movements and down speed is gained by world reknown Rexroth valves, which are able to respond quickly to the commands, as well as with its pressure compensation. Unwanted speed differences are eliminated during solid material cutting and no harm is done to the saw edges. All electrical control components are selected from Siemens and Schneider.
DCBS SERIES BANDSAWS FEATURES RIGOROUS RESEARCH & DEVELOPMENT EFFICIENT POWER & FASTER CUTTING ABILITY All mechanical, hydraulic, and electrical systems of the DCB series Durma band saws are designed by experienced Durma R&D engineers by using parametric 3D technology. All models are subjected to rigorous testing prior to going in to serial production. The saw turns on pulley which is driven by high torque helix gear box and electrical motor. Even in continuous working conditions no heating or torque loss occurs. The torque is transmitted to the saws with any power loss by a drive system guided with strong conical bearings at the same axis as the pulley. Because of the high torque design the cutting speed is much higher than the other machines in the marketplace. The frequency inverter provides protection for the tape and other components against possible overloads at peak pressure. LONGER BLADE LIFE STRESS RELIEVED FRAME While saw blade is tight between the pulleys it tends to twist between the guides vertical to the table. The level of twist increases when the tape is on its maximum angle and minimum distance to the work piece. This causes very thin fractures on the blade which can cause breakage to the blade. Deflection and vibration during the cutting process are minimized by the reinforced frame. The rigid frame is connected to the strong chassis by chrome plated columns. Chassis, body and all other parts are stress relieved after casting and welding. All machining is performed with five axes. CNC working stations, with single pass. In this way, mounting surfaces for all axes are guaranteed to be parallel. The combination of these processes ensures precise and long lasting operation.
DCBS SERIES BANDSAWS STANDARD FEATURES TWOWAY 45 ADJUSTABLE CLAMP HYDRAULIC VICE In semiautomatic models the work piece clamp can be manually adjusted 45 o to the right or left to create miter cuts. One of the most important factors for cutting quality is to securely clamp the material. Hydraulic vices are used to prevent any movement of the material during the cutting process. BEARING & CARBIDE TYPE BLADE HOUSING When the right saw tape is used, the steepness and tangential of the cutting is mostly depends to tape guiding. Ideal cutting is achieved by carbide metal guides for the tape side surface. Due to their vertically positioned bearings, proper gap and parallelism minimizing tape and material costs and finishing operations eliminated. CUTTING SPEED ADJUSTMENT BIMETAL BANDSAW & COOLING SYSTEM Proper cutting speeds are very important in achieving optimum cuts. Variations in the cutting speed can affect the cut quality as well as decrease blade life. The cutting speed is easily adjustable on the digital control panel. As a standard one general purpose bimetal band saw for general is supplied with the machine. Different sizes and blade profiles can be supplied upon request. A water based boron oil is spread with desired flow to the tape bed and cutting area with a strong centrifugal pump. Machine is shipped without oil.
DCBS SERIES BANDSAWS STANDARD FEATURES BLADE TENSIONING HYDROMECHANIC An easily accessible blade tensioning device with pressure gauge allows quick and easy setting of the blade tension. In the event of a blade rupture, the system stops. TOP CLAMPING MECHANICAL Mechanically adjusted top clamping secures bundled material during the cutting process. PART COUNTER With automatic models it is possible to enter the number of cuts to be achieved during serial cutting. In addition, the display also displays information about the machine, alarm and cutting. MOTORIZED ROLLER FEEDING MANUAL CHIP BRUSH Removing the chips between the tapes is very important to increase blade life. A manual chip brush cleans most of the chips and prevents the dirt gathering on the body. Chain driven rollers provide a simple and fast material feed system for general purpose cutting. CUTTING HEIGHT ADJUSTMENT Fast and easy cutting height adjustment saves setup time, especially during production or serial cutting.
DCBS SERIES BANDSAWS STANDARD FEATURES LENGTH ADJUSTMENT ELECTRICAL ROLLER TABLE Cutting length adjustment of the material in automatic models are done by adjusting limit switch to the desired cut length. Maximum setting is 23.5. During serial cutting cuttings, a roll driven vise feeds the material to the preset length can the material is cut. After completion of the cut, the piece falls and the process is repeated. At the front or back side of the machine the table provides easy material entrance by bear driven rolls. One table is standard with the related machine. Extra tables can be put together, this way longer materials are supported.
DCBS SERIES BANDSAWS OPTIONAL FEATURES CHIP CONVEYOR BLADE TENSIONING HYDRAULIC A large amount of chips can be produced, especially when cutting solids. The motorized chip conveyor automatically transfers these chips out of the machine. Provides blade tensioning via the control panel without the need for operator to manually set. When ideal tension is automatically achieved. In the event of blade rupture, the system stops. MOTORIZED CHIP BRUSH LASER MARKING A motorized chip brush is available in lieu of the standard. TOP CLAMPING HYDRAULIC It helps length adjustment of the work piece. The laser line reflecting on the front side of the tape allows easy viewing of the length and the cutting line. The blade is positioned higher than the material during feeding process, avoiding any blade damage. This system is a convenient feature in semiautomatic machines and special cutting applications. Hydraulic top clamping. MOTORIZED ROLLER TABLE 118 MICROSPRAY COOLING Motor driven feed rollers help in the material feed or discharge process for heavier applications. Extra tables can connected together in order to support longer material. A special mixture of micronized cutting oil and air is sprayed on the blade to prevent overheating and to increase blade life. In addition to the ecological advantage it also minimizes the boron oil costs.
DCBS SERIES BANDSAWS OPTIONAL FEATURES NC CONTROL SYSTEM Programming of the cut length as well as the number of pieces to be cut. Certain machine parameters can also be set through the control. An encoder is integrated in to the clamp rollers to provide the precise positioning to the programmed length. AUTOMATIC CUTTING PRESSURE CONTROL Automatic setting of the cutting presure assures optimum cutting. If the speed is too slow or too fast it affects the cut quality and shortens blade. Automatic cutting pressure control also prevents overload to the machine. EXTRA ROLLER TABLE 47 TURNING TABLE At the front or back side of the machine the table provides easy material entrance by bear driven rolls. One table is standard with the related machine. Extra tables can be put together, this way longer materials are supported. The saw body can be mounted on a manually adjustable turntable a time and space saver.
