The fundamental relationships between grain orientation, deformation-induced surface roughness and strain localization in an aluminum alloy ... used to determine the set of ten displacements at which the sur-face conditions would be assessed. There are probably companies in your area that offer this service. We have not been able to achieve a top quality finish with this alone. Chat Now Send Inquiry; Aluminum sheet - Aluminum - ThyssenKrupp Aerospace. This machine has a series of heavy duty rollers that moves the part through. Does Aluminum plate stock (7075) have a grain direction that is significant enough to make a differance as to which direction a part should be made? Bending with the grain gives a different result than bending against it. When it digs in like Larry said too much pressure. In addition to the new "bounding box" sketch, there is a new option in the property manager for the Flat-Pattern feature: "Grain Direction".You can define a grain direction to use when calculating the bounding box for sheet metal parts. The L direction is the direction the aluminum sheet is rolled, therefore the grain axis is aligned with the longest axis of this ellipsoid. A. I think most would choose aluminum oxide, but others will work. T351 here refers to the ‘Temper’ produced using heat treatment. Grain direction is usually specified on stainless steel and other hard materials when it is necessary to maintain minimum bend radius or to control spring back on parts with large radius forms. Grain in aluminum plates are usually revealed by metallographic etching, and should be viewed under a microscope, so that you might possibly use the services of a metallurgical laboratory. I used 1/4" sheet rubber to make a sleeve around the platen and reversed the feed motor and it got the grain using 80 grit then 120 grit. *Eng-Tips's functionality depends on members receiving e-mail. You can’t read fiber direction just by looking at the surface you want to plane, however. The forging process has also aligned the grains of the metal in a direction similar to the flow lines in this picture. To minimize search efforts and to offer multiple viewpoints, we combined previously separate threads onto this page. Can anyone help me or direct me to the proper machine. I've never seen sheet metal (aluminum) bought this way, but that may be available also. But first, let us look at the material grain directions L, LT and ST. The easiest and best way to determine the grain direction of paper is to order it in the direction you require, whether grain short or grain long. Promoting, selling, recruiting, coursework and thesis posting is forbidden. Metallographic etching is a chemical technique used to highlight features of metals at microscopic levels. A. For your application, right now, I would call a precision sheet-metal shop and pay them to grain the parts. Might be we are not using the correct machine. Already a member? The reason is that I have been told to never bend this aluminum parallel to the grain. This can be done extremely fast and should be relatively inexpensive, especially when you consider how much time you are spending "experimenting". Thanks Patrick & Larry. I tried a belt sander and it embeds small aluminum flakes in the metal and I get a rippling effect in the grain. Q. The belt sander is a 13" x 32" from harbor freight. ©1995-2020 finishing.com, Inc., Pine Beach, NJ   -   About finishing.com   -  Privacy Policy Paper grade will be 120 or 220. Which, by the way, is exactly why I asked the pros. Search the site My theories are that a longer belt is less likely to leave a straight line grain or a belt rotating slower does. The axis dimension in the two other directions, LT and ST, is much shorter than the L direction. After that, you will have to make a decision to buy one or continue to sub-contract this process. Also, the grain looks identical on the 304 and 430 stainless steel, but the protective film may be different colors. } Typically, a brushed, or grained, finish is done prior to anodizing, with an apparatus similar to a belt sander (I'm sure its much more than that, but I'm not an expert on finishing machines). Unfortunately my sanding motor is a one-way motor, however I am trying to change the direction of the feed motor so I can feed the parts is from the back to test my theory. or benefit from 30 years of feedback on 60,000 finishing topics. In this report, image analysis is used to determine the grain size distribution for seven specimens of anodized aluminum: three samples of Al + 1.0 Si, two of Al + 1.0 Si + 0.5 Cu and two others of Al + 0.5 Cu. LOL. That's about what I thought too, but ceramics seem also to have popularity. Grain Size Characterization of Aluminum Alloys. of a grain refiner is assessed by the grain refining curves. Login. Cause if it's not, the grain is a lot harder to find, which is fine because it's also a lot less important — cut your own filets and porterhouses the way you like. I think the largest is in impact properties: No, Goahed, no exaggeration about my knowledge of metals, and from all the information you and the others have provided, assures me that I am out of my league and should not attempt to perform any fabricating. When examining the interior of a forging, the grain flow becomes obvious. "palette": { Precautions in use. The piece is a fitting on an aircraft. Copyright © 1998-2020 engineering.com, Inc. All rights reserved.Unauthorized reproduction or linking forbidden without expressed written permission. The grain in rolled, Al alloy plate looks exactly as expected: Elongated in the longitudinal, broadened in the transverse, and squashed in the short transverse. In such instances, the T73 temper should be considered, at some sacrifice in tensile strength. A. Hi guys we are polishing aluminium with a grain satin finishing. "background": "#fff", The clues to look for are on the edge adjacent to the surface you’ll plane. The grain direction of the metal also contributes to the amount of springback that occurs in a bending operation. new LazyLoad(); Uses approx. a grinding belt that has been treated with stearine wax or any such "grease" compound may relieve the spalling effect that is marring the grain finish you require. & Install'nChemicals & Consumables HomeFAQsSuggestedBooks 6 hours straight, before shut down. Ask around and see if you can find someone in your area that has a TimeSaver machine. It is one of the most commonly used materials in the aerospace industry. The feed must not be against the direction of the belt but with it. After the forging has been sectioned, it needs to be ground and polished similar to a metallographic sample. We have been deep in attempting to brush aluminum for over a year now and are just coming around the corner for a process. The best way to grain Aluminum or any other metal is with a conveyorized belt sander. They do a wonderful job, they are very consistent and they aren't too unreasonable to pay to have done. Loosen drive belt to clean out the gray mud with a rag. I sort of get the desired grain from scotch-brite fine belts but the grain is not deep enough. P.S.. WE DON'T REALLY HAVE A PROBLEM WITH BELT LOADING UNLESS THE BELT IS SHOT OR TO MUCH PRESSURE. The software determines the smallest rectangle (bounding box) that aligns with the grain direction to fit the flat pattern. First, my sander is sanding at about 1500 sft. This also depends on the grade of finish you require coarse or fine. When the output of the linear Grain direction is noted on most paper packaging, swatch books and paper mill stock sheets in one of a few different formats. The material we will consider is Aluminum Alloy 2024-T351. Here is the machine info: The acid will etch the surface, revealing the grain flow pattern. These groupings of molecules manifest as irregularly shaped crystals or crystal-grains. Polycrystalline materials are solids comprised of a variety of differing crystallites, which are also commonly referred to as the grain of the metal. To plane the top (1), look at the side (2). There are machines that do this finish on sheet material. You could try asking some offset production machines supplier. A. Reasons such as off-topic, duplicates, flames, illegal, vulgar, or students posting their homework. the clues to fiber direction are on the surface of the wood. Most metals are crystalline in nature and contain internal boundaries, commonly known as “grain boundaries.” When a metal or alloy is processed, the atoms within each growing grain are lined up in a specific pattern, depending on the crystal structure of sample. . As a general rule, the grain line must run perpendicular to the bend to avoid the potential for cracking or fracture. I need to know how to tell which way the grain runs. Grain size can be reduced by a process called grain refinement. }); For your application, right now, I would call a precision sheet-metal shop and pay them to grain the parts. I'll probably be out of business by the time I figure this out on my own. Texture or grain direction must be taken into account for accurate predictions of material behavior and characteristics when forming/bending. Q. I think I have narrowed the loading problem down to 2 possibilities. All information presented is for general reference and does not represent a professional opinion nor the policy of an author's employer. })}); 60,000 Q&A topics -- Education, Aloha, & Fun, [last name deleted for privacy by Editor], metal polisher - Christchurch, New Zealand, electri-cable assemblies - Shelton Connecticut, Machine Operator - San Marcos, California, US, ©1995-2020 finishing.com, Inc., Pine Beach, NJ, How Google uses data when you visit this site. The internet is largely anonymous & unvetted; some names may be fictitious and some recommendations might be harmful. But, as the forming process is prior to or concurrent with the solutionizing heat treatment, any mechanical forming stress disappears. A. Caution should be exercised in T6 temper applications where sustained tensile stresses are encountered, either residual or applied, particularly in the transverse grain direction. If your tools are sharp and you’re cutting with the grain, your woodworking experience will be an enjoyable one. To achieve the best long line grain in aluminum you need a stroke sander and a 80G silicon carbide belt. My personal favorite is Timesaver brand but there are others such as Ramco that do an adequate job. elements_selector: "iframe" Aluminum … In the metallographic laboratory, analyzing grains in metallic and alloy samples, such as aluminum or steel, is important for quality control. P.S. The observation of the grain flow in this figure requires some special preparation methods. Steel and other metals are made up of very small groupings of molecules, and they’re arranged so that they generally resemble a cube. And on the others, locate the direction the "lines" or fibers of the meat are running. Thanks. These grains vary in size and in orientation but are usually microscopic and their direction is determined by the processing conditions. The observation of the grain flow in this figure requires some special preparation methods. Please let us know here why this post is inappropriate. Guy. YOUR PROBLEMS ARE EXACTLY THE SAME AS MINE. I think the loading and the embedding of aluminum particles was due to the fact the wide belt sander was designed for wood. I think that may be too slow for metal because all the major's like TimeSaver and AEM run about 3000 SFT. Oxidation Etching By joining you are opting in to receive e-mail. The two main problems were feed direction and platen hardness. I am trying to make optical microscopy analysis of samples of aluminum alloy (AA) 6082, AA 6082-T6 and pure Al. Also, pulling on the roll of water filter in the back of machine below where the parts come out. Consult'g, Train'g, SoftwareEnvironmental Compliance. They are far too slow and labor intensive to grain multitudes of parts. The most common way to determine the grain direction on the face of a board is to examine the grain lines on the edge of that board. I wish I had bought the stroke sander. Better to ask a naive question than to do something stupid. They have this old rusted red machine that does exactly that ... using 100 grit, for materials that is 0.040 - 0.125, uses & holds 2.5 gallons of water based oil coolant mixture, with a rubber conveyor belt that moves the parts through. Flood the face of the steel with acid, and as soon as the surface begins to etch, wash the acid off with pure water.
