Define of stone band saw machine
Stone Diamond band saw machine is one of the high precision cutting machine for sawing stone slabs or blocks into thin slab. Band Saw Cutting Machine is used for horizontal cutting thin slab in to slicing pieces. It can processing marble, also this band saw machine can also cutting small size block into slabs. This machine is easy to operated and high working efficiency. It is joined design, stable cutting. All of its components are used high quality.It uses a closed and ring diamond band saw blade as the sawing blade, stone band saw machine is popular because of it’s high efficiency and high quality for stone cutting. This stone diamond band saw machine is similar with wood cutting machine. The difference is the diamond saw blade is welded with diamond serrations on one side of steel strip, and the steel strip is a blade body without joints or two ends are welded together to form a closed loop, so it is called band saw machine. The main difference between stone band saw machine and marble gang saw machine is the body of band saw is a flexible steel strip, which not only requires diamond to be inlaid and welded firmly, but also can rotate and bend like a belt.
Working principle of band saw machine
When stone band saw machine is cutting, the motor drives the driving wheel, which is transmitted to passive wheel through diamond band saw blade, so that the band saw blade can sawing slab or block rapidly in one-way cycle and make reciprocating linear motion under action of the system to cut thin slabs. Some stone band saw machine can install only one saw blade while some machines can install multiple diamond band saw blades, it means we can cut many pieces of stone materials at one time with the multiple blade band saw machine. And the space between each saw blade can be adjusted also to meet different customer request. With this advanced design, we can greatly improving cutting efficiency and save cost.

Stone Diamond Band Saw Blade
Band saw blade is usually very thin (thickness is about 1-2.0mm) and very long (about 5-8m). Small band saw blade is mostly made of electroplated consolidated diamond abrasive. The most widely used method is to weld diamond tooth on two edge sizes of band saw body, that is, to use diamond segment. In general, sawing gap of the blade is about 3mm. We must know that different stone materials need different stone band saw blades. It’s very important to select high-efficiency and long-life diamond segments, especially pay attention to quality of the segments, so as to reduce cutting cost and improve productivity. For steel substrate of band saw blade, we need to choose a steel strip with high bending fatigue strength. Hardness is not the most important factor, because the body does not directly join in the stone cutting. There is a precision and strict request on tension of stone band saw blade and the tolerance of band saw blade must be controlled within 0.05mm on a 1000mm length blade. At the same time, it is required that steel body on the band saw blade should be re-welded well, generally one new band saw blade can be re-welded for 3-5 times. Body of diamond band saw blade is a thin steel strip, with very poor rigidity and this rigidity is mainly guaranteed by tension. Theoretical analysis and experimental research have proved that a small deformation on band saw blade will affect the sawing quality and smooth sawing speed. There are two ways to affect deformation of the band saw blade: one is lateral deflection caused by lateral load, the other is instability deflection of band saw blade under the action of critical normal force. The higher the tension is, the less possibility of bending deformation and instability deflection of the saw blade is. However, if the tension is too high, internal stress of the band saw blade will be too large, which will affect lifetime of the saw blade. The tension should be controlled properly to meet the rigidity requirement of band saw blade. Under this premise, the fracture of band saw blade is often due to reduction of fatigue life of band saw blade. Diameter of the pulley is directly proportional to the bending stress. The larger the pulley is, the smaller bending stress is, which is beneficial to improve fatigue life of band saw blade. However, the increase of belt wheel will increase structure of saw and length of saw blade. Generally speaking, thickness of band saw blade used for sawing hard granite is higher, and the pulley should be made larger accordingly; the thickness of band saw blade used for sawing soft marble is smaller than that of the pulley.
Specifications of band saw cutting machine
The processing parameters of stone band saw machine mainly include band saw cutting speed, band pressure, feed speed, band tension, stone size, sawing guide device and cooling lubrication conditions. The sawing speed is determined by type and width of stone, and pulling force of band saw belt. The harder stone material must use lower sawing speed; the smaller size of block or slab must use faster sawing speed. The pressure and feed speed of band saw belt are determined by type of stone and cutting size. For harder and wider stones, larger pressure and feed rate shall be used; for softer stones, smaller sawing width, smaller pressure and feed rate shall be used. Select the most suitable type of band saw blade according to size of sawing stone; then select width of band saw blade according to minimum radian (radius) of the required sawing material. The smaller the radian (radius), the narrower width of band saw blade. Before start using a new band saw blade, check its tension first. If necessary, tension after a small amount of cutting test. The pretension stress of band saw blade should meet requirement of matrix strength. In most stone sawing processes, cooling and lubrication are indispensable, which can not only cool diamond saw blade, but also wash off the stone chips and dust to improve sawing quality. One of the common problems in the use of diamond stone band saw machine is the saw blade often breaks, and effective life of stone saw blade is far from expected life, which makes diamond segment unable to give full play to the cutting performance. When using stone band saw machine to cut stone material, it is often necessary to apply a large tension force on band saw blade in advance. There are two functions of tension force: one is to generate enough friction force between band saw blade and contact surface of belt wheel through the tension force, so as to transfer effective driving force required by work and prevent band saw blade from moving in series along belt axle under normal force; the other is to improve rigidity of band saw blade, prevent blade from flexure, deformation and instability deflection, so as to ensure certain sawing efficiency and straightness of SAW seam. The former requires much less tension than the latter, so when setting blade tension, we should mainly consider to ensure the rigidity of band saw blade.
