Commonly used cutting method of titanium plate
Titanium is cutting the conventional sawing, milling, punching and shearing and other methods.
Band saw. Band saw processing more efficient, easy preparation, but not suitable for processing thin material, commonly used in the thickness of 3mm above the titanium plate. This method does not produce edge cracks. The disadvantage is that bur, cutting must be polished. More are currently used for trimming, trimming and cutting the end of the process.
Band saw cutting can be divided into three categories: fiction, semi-friction and ordinary band saw. Friction band saw work due to the high linear velocity, severe friction between the saw blade and the workpiece, the cutting zone temperature is soaring, thus reducing the cutting resistance of the material, improved workability, high efficiency.
Saw bands for sawing should be rigid, with sufficient power to keep a constant rate of sawing, automatic feeding, tension band saws, and adequate coolant. the usual high-speed steel band saw will be able to maintain the blade, and get a stable result. Tungsten carbide cutting blades are used to see exceptionally thick materials, reducing burr height and heat affected depth.
Milling cut. Milling a stack of titanium plates with a milling cutter to the desired shape, milling head along the milling model movement, or automatic milling with a larger CNC sheet metal milling machine. For the concave curve or flanging and other stretches of the edge, the shape of the front waist polished to prevent cracks.
Cut. Create straight line shape of wool or parts, can be cut in the gantry shear bed. If using ordinary shears, to carefully check whether the equipment can cut titanium plate. Titanium alloy plates with a thickness of 35mm or less have the ability to cut the required size under production conditions. If you take the necessary action to avoid slippage during shearing, thicker plates can also be sheared. In order to avoid slippage, the need to use a larger clamping pressure. On the edges of sheared titanium plates, especially for thicker titanium plates, the straight line deviations are 0.25-0.50mm. This deviation is typically caused by the lack of rigidity of the shear blades. Use thicker cutting edge, and sometimes will overcome this defect. If retrofitting blocking device, and the use of digital display, fine-tuning and other technologies, but also will increase the accuracy of feeding. Titanium edge cracks no more than 0.4mm deep, available grinding wheel and file repair and other methods to remove. If the shear will cause the key parts of the crack, you should consider the use of band saws and the like cutting method. When cutting with a gantry shearing machine, the minimum gap between the distinct sides of the scissors is 2-3% of the material thickness, the shearing angle is 75 degrees -85 degrees and the clearance angle is 2 degrees -3 degrees. The inclination angle of the cutting edge on the shearing machine 2 degrees -5 degrees.
Titanium can also be used for ordinary cutting equipment cutting. Round cut radius curvature radius of the contour (minimum radius of about 250mm). This method is used for the thickness of 2.5mm F below the titanium plate. The current vibration shear is only applicable to shear thickness of about 2mm of titanium plate, cut the edge of the wool must be file repair or grinding, leaving 0.25mm or more file repair margin. For thin material (thickness <0.8mm), when the quantity is small, it can also be cut by hand or by hand.
Die cut. Generally punching the punching the desired shape of the wool. Usually for simple shape of wool, the maximum thickness of about 3mm feeding. Titanium die should have sufficient rigidity, the guide column so that the upper and lower mold to maintain accurate relative position. The manufacture of a variety of flat parts or a variety of shapes of wool, the minimum size of titanium punching, blanking parts meets the minimum radius of the edge should meet the requirements.
In addition, the blanking machine can also be used to cut the material when processing according to the template to a small punch out of the crescent-shaped incision and make it connected to cut out the parts burr, and then repair the key edge, the edge of the quality and accuracy are not punching die, Efficiency is not high. The advantages of punching processing are short preparation cycle, commonly used in small batch production.
