A milling machine includes a cutter that functions at a high speed. Hence, it can harm the user if not operated properly. Moreover, the milled material may cause serious injuries, because the metal chip is very sharp. Further the metal pieces lying on the table can cut your skin; and the metal flakes flying around during the cutting process may damage your eyes. It is therefore necessary to be careful and alert while operating. Hence all related persons are advised to follow the safe guards listed below.
• You should make sure that your hand, shirt sleeve, glove, and long hair are kept at a safe distance from the milling machine, especially the spinning parts. Otherwise if anything gets entangled in the moving parts it will cause serious mishaps. Hence you should always be aware about the location of the stop button for immediately disconnecting the power supply, if an accident occurs while working.
• Usually a sharp metal rotates at high speeds on a milling device. Hence you should ensure that the work piece is fastened tightly. It is better to secure the material properly to avoid it from flying off the table and prevent any damage or accident.
• You should even secure all the tools in the relevant tool holders. This is essential because any loose tools can injure you or damage the machine. Further, if a tool breaks, you must instantly stop the tool and change the tool, and repeat that operation. Moreover the broken tool may also collide with the nearby tools in the line, and thus cause various other problems.
• Basically the metal which is being cut on a milling equipment has sharp edges. These dangerous metals should always be handled with care; otherwise it can cause considerable damage. Moreover, as some milling machines may not be enclosed, it is necessary to safe guard your eyes from the sharp metal chips and the coolant spray. Hence when you are working with raw metal; you must wear safety gloves and suitable eye protection.
• While operating it you should always close the doors and view the process from the window of the machine. This window will protect you from any loose parts, and sharp or large chips of metal. Moreover before starting the milling machine you should always clean the window whenever it gets dirty, and also replace it when it is damaged.
• Generally a water soluble fluid is used to cool the metal when it is being cut. However, a coolant may not be utilized for machining some metals. As a result the hot metal chips that are thrown off the work piece can burn your skin. Hence you must always use a shield while machining soft metals without a coolant. In case a safety cover is not available you should use a fire resistant material as a temporary guard.
Hence all users should know these important safe guards while operating milling tools.
A press brake is primarily used for accurately bending various types of metal sheets and plates. Some frequently asked questions are as follows:
Q. What is camber?
A. Camber is actually a small piece of cap which is placed on the ram or bed to permit deflection. This is due to the fact that, any material which is bent on a it will encounter resistance. As a result this resistance will deflect the bed as well as the ram.
Q. Is it necessary to fasten the machine to the floor?
A. Definitely, the press brake must be first leveled and then properly fastened to the floor. Otherwise 25 percent of the energy of your press brake will be wasted, due to loss of torque.
Q. How much tonnage is required for a specific task?
A. Please refer the chart on the press brake which displays the amount of tonnage needed for a specific kind of metal. For example, you can press a 0.25 inch steel plate at 15.4 tons per foot. Further, in case you are using a 0.125 inch sheet, it can be pressed at 7.7 tons per foot.
Q. Explain tensile strength and yield strength for a press brake?
A. The term tensile strength is used when you are referring to pressing a metal piece. This includes applying lots of force at a particular place on the metal piece to accomplish the task. Whereas yield strength refers to applying relatively less force in order to roll a metal piece. Hence in order to press stainless steel or any other metal, you will require a larger press brake as the tensile strength is more than 80000. On the other hand, for rolling stainless steel, you may use a smaller capacity press brake. For example, a 304 stainless steel work piece actually has a tensile strength of 95000; while the yield strength is just 35000.
Q. Why is it essential to designate the various materials?
A. Material designation is important as well as mandatory, since it provides us the detailed information of a particular metal; including the tensile strength and yield strength. Moreover, it is also necessary to ensure that you have the complete designation of a metal. For instance, A516 is incomplete and not sufficient. You must also include the grade. Hence A516-55 means that the tensile strength is 55-75000 and the minimum yield strength is 30,000. And A516-70 refers to tensile strength of 70-90,000; and minimum yield strength of 38000.
Q. What is the maximum capacity of a press brake?
A. The maximum capacity is basically, the rated tonnage of the tools. Hence you should find out the relevant tonnage per foot, and then just multiply the tonnage by the number of feet you require. However, while using short pieces of metal, it is always advisable to slightly move the work piece in order to prevent the bed from getting damaged.
Hence these FAQs on press brake will help potential and existing users to solve their queries.
The various sheet metal machineries for shearing, bending and cutting are described below:
The mechanical press brake has a sturdy frame built from high grade steel. It also consists of steel plates with appropriate thickness and machined guide ways.
