Types Of Metal Fabrication -- Bar Milling, Press Brake Forming, And Sheet Metal Fabrication

Experts in metal production use a number of varying techniques to manufacture custom fittings, parts, and other commercial and industrial solutions. Every technique can produce a totally different product with unique characteristics. Regardless of whether it's press brake forming, bar milling, or sheet metal fabrication, each of these techniques has its own advantages. This article looks at these three main types of metal production.

Bar Milling

By reforming an existing metal bar into a certain length, shape, or form, bar milling can help fit metal to specific jobs just like when you use a router on wood in furniture making. It can take traditional square or round bars and turn them into angled or hexagonal bars. Bar milling also allows for adding grooves and other features. This process can be used with several materials, including stainless steel and brass. To make each shape, an expert designs a series of cutters that might include slots, roundovers, bevels, or other shapes. Then, the piece is milled down until achieving the proper dimensions and a smooth feel.

Press Brake Forming

With a computer operated machine that is capable of high pressures of up to 350 tons, press brake forming squeezes metal into the shape you want. Some machines can even work with material up to 3/8" thick and approximately 12' in length. The press brake forming process works with a number of materials that include carbon steel, stainless steel, brass, and aluminum.

Press brake forming has many uses. It can make metal framing, brackets for equipment and machines, metal housing for a specific part, or even decorative metal touches for sprucing up anything. It is a great solution for people who need prototypes for equipment and machinery, large numbers of brackets, fastening solutions, or replacement parts.

Sheet Metal Fabrication

Perfect for precision cutting and detailing, sheet metal fabrication allows experts to use welding, press brake forming, laser cutting, shearing, and punching to create just about anything from this thin and versatile metal. It is used for products from hopper bottoms and cultivator shovels in the agricultural industry to decorative pieces, guards, frames, conveyor parts, and more for a number of other industries.

Sheet metal fabrication is used to form many types of frames and covers. It can also work as a cover for a column or in ventilation. Fasteners and other types of components are often made with sheet metal fabrication, including parts in the conveying, transportation, and refrigeration industries. Even recreational activities like amusement park rides are enhanced through sheet metal fabrication.

Depending on the type of project, any one or all three of these types of metal fabrication techniques can be used. Once the metal is fabricated, welding connects everything to provide a finished project. Upon completion, a quality provider usually checks the project for accuracy, quality, and durability before giving the okay. Whether press brake forming, bar milling, or sheet metal fabrication, there is a metal production technology out there that can produce exactly what you need.

 


Glass Grinder Bits

There are many tools that are essential to complete a handyman's arsenal, and a glass grinder is one of the tools that are less frequently used but still important. A grinder bit s used to cut pieces of glass, and it is a specialized tool that is only used for glass. Know what grinder bits do and how to use them is an important part of finding and purchasing one.

Glass grinder bits are actually separate bits that do not come with a set of Dremel tool bits, but you can easily find your own grinder bits. They are shaped similar to the other bits for the Dremel tool, but you can tell them apart by the fact that the edge of the grinder bit is sparkly. This is because low grade diamonds are used to cut glass.

Using glass grinder bits is actually fairly easy, and you can cut easily using the following steps:

Step 1: Outline on the piece of glass the design or shape that you want to grind into the glass. Usually you will need to draw the desired design for your piece of glass, as it is difficult to keep the Dremel tool to a particular path if it is not clearly laid out. You can use a marker, although many cutters use a grease pencil to make the markings on it.

Step 2: Grinding the design into the glass begins by selecting the right grinder bit for the job. Glass grinder bits come in all different sizes, and you need to select the right size bit for the grinding that you will be doing.

Step 3: Attach the grinder bit to the Dremel tool according to the instructions. Be sure to tighten the Dremel tool properly to ensure that the grinder bit doesn't spin out as you are using it. Glass grinder bits can be dangerous if they spin off a Dremel tool, so it is vital that you secure it properly.

Step 4: Begin at the outer edge of the piece of glass, and begin grinding in towards the center.
Follow the pattern that you have outlined in it, and make sure to do the outer designs of the glass before getting to the middle portion of the glass. Doing the outer areas first ensures that the glass dust doesn't build up and obscure your view of your grinding. You will often need to brush away the dust as you work, as the dust will build up as you use the glass grinder bits.

Step 5: Once you have finished grinding the glass, turn off the Dremel tool and set it aside carefully. To finish off the grinding, you can use a sanding bit for the Dremel tool, and use it at a medium setting to give your outline a good rub down. This will create a frosted, even, and smooth appearance that makes glass look elegant.

As you can see, using glass grinder bits is fairly easy, and you can easily buy your own set of glass grinder bits to allow you to etch fancy patterns and designs. You can even create your own stained windows if you get good at using the grinder bit.

 


Using Hardwood Floor Sanders

Refinishing your hardwood floors yourself can be time consuming and a bit scary at first but well worth it in the long run. It can cost a bundle to hire a professional to refinish your floors for you, but if you have the time, you can do it yourself. The most difficult part is learning to run the sander. Many people are afraid of ruining their floors, and you can really damage a floor if you do not take care in the sanding.

Sanding is fairly easy if you pay attention and the finish does not take as long to dry as you might have been led to believe. You can rent a sander from your local Home Depot or hardware supply store. Youll need a drum sander, a belt sander or both. They will explain to you how to use the machine and tell you what kind of sand paper to purchase. They will also tell you what kind of stain and finish to get. Make sure you also pick up some dust masks because you will have saw dust everywhere.

The key to a good floor finish is the surface, so the most important thing when learning how to run the sander is getting a feel for the equipment. Sanders are not as hard to use as you think. They are loud and messy, but fairly easy to operate. Just keep the sander in motion at all times. Moving the sander in a constant motion will reduce the risk of damaging your floor. Equate it to using an iron on your clothes if you stop in 1 spot too long youll burn a hole. The sander is similar since it creates a lot of heat, keeping it in 1 spot can burn or dent your floor.

The sander is a self propelling machine so it is easy to move, but you do need to keep in control of it at all times. Retain a firm grip on it when you power it up and you will get the hang of it after a few passes. You might even think its fun!

Once you have removed to old finish by sanding, of course, you will need to apply the new finish. First you will apply a stain (if you want a stain some folks like to leave their floors natural) and then the finish to protect the floor. There are basically two types of floor finishes: one is oil-based and the other is water-based polyurethane. Furthermore, oil is broken down into a semi-gloss, gloss or satin.

Satin is a good choice for a hardwood floor because it hides small flaws and lets the natural beauty of the wood show without a bright shine. An oil based finish will give your floor a warm amber glow. A water based finish will dry quicker and keep from yellowing.

Make sure you let each coat thoroughly dry before applying the next. Follow the manufacturers instructions on the finish before you occupy the room again. Usually you can move your furniture back in after about 24 hours.

Dont be overwhelmed. Just take it one step at a time and youll soon have a beautiful new hardwood floor.
