Cutting-stock For Titanium Plate And Titanium Slab
Sep 12, 2016

           Titanium plate mold material should have sufficient rigidity, with the guide posts so that the lower mold to maintain accurate relative position. The manufacture of a variety of flat pieces of various shapes or wool, the minimum size of the titanium plate punching, punching parts joined edges of minimum radius should meet the requirements. Press the template to punch out a small crescent-shaped incision during processing, and it is connected, thus cutting out the burr and repair key edges, the edges are not as good quality and precision die stamping, efficiency is not high. Advantages punching process is to produce a short prep aration period, commonly used in small batch production. Before forming first titanium cutting. Titanium is also using conventional cutting sawing, milling, punching and shearing and other methods. Due to the large titanium strength, and therefore differ from the aluminum cutting. Here are some ways:


  Band saw. Band saw higher processing efficiency, facilitate the production ready, but not suitable for processing thin material, commonly used in titanium cutting thickness of 3 mm or more. This method does not generate the edge crack, the drawback is a burr to be polished after cutting. Currently more for cutting, trimming and cutting end processes. Band saw cutting can be divided into three categories: friction, friction and half ordinary band saw. Due to the high speed line, occurs when the friction between the band saw blade and the workpiece work intense friction, high temperature in the cutting area, thus reducing the cutting resistance of materials to improve the workability and high efficiency. According to the band saw with titanium should be rigid structure, to have enough power to maintain a constant speed when sawing; should be able to automatically feed the tension band saws and provide sufficient coolant. The usual high-speed steel band saw blade will be able to maintain and get consistent results. The blade material is tungsten carbide saw blades for cutting particularly thick, can reduce the depth of the burr height and heat-affected.


  Punching. Generally in the wool punch a punching out the desired shape. Usually simple shapes wool, cutting the maximum thickness of about 3 mm. Titanium can also be expected under ordinary rolling shear equipment. Circular shears can cut large radius of curvature of the contour line (minimum radius of about 250 mm), this method is used a titanium plate thickness of 2.5 mm or less. The current vibration shears apply only to cut a thickness of about 2 mm titanium plate, wool edge clippings file must repair or grinding, to stay 0.25 mm or more file repair margin. For thin material (thickness <0.8 mm), while a small number, can also be used by hand or lever type hand shears cut material.


  Milling. With a stack of titanium milling cutter to the desired shape, milling head milling template movement along, or with a large sheet metal CNC milling machine automatic milling. For a concave curve or the like by stretch flanging edge, forming Frontal polishing, to prevent cracks.

 Cut. Fabrication of the linear shape of wool or parts can be cut at Longmen shears bed. If ordinary shears, to carefully check whether the device can cut titanium plate. Thickness 35 mm titanium plate has been able to cut out the desired dimensions under production conditions. If you take the necessary measures to avoid slipping when cutting, it is more thick sheet can be cut. To prevent slipping, required greater clamping pressure. On the edge of the titanium plate shear, especially for thick titanium plate, linear deviation is 0.25-0.50 mm, this bias is often due to lack of rigidity caused by the cutting edge. Changing to a thicker cutting edge, sometimes we will overcome this defect. If the modified block feeding device and digital display, trimming technology, but also improve the accuracy of the cutting. Titanium edge crack depth not more than 0.4 mm, the grinding wheel can be used with file repair and other methods to remove. If the key parts of the cut parts will crack, you should consider using a band saw cutting method or the like. When using gantry cutting bed material, the minimum clearance between the scissors-sided 2-3% of the material thickness, cutting angle of 75 degrees -85 degrees, after the angle of 2 degrees -3 degrees, inclined blade cutting edge inclination angle of the bed 2 degrees -5 degrees.
