Metal Fabrication Machining

At Bormill Inc., our facilities employ a large value of added processes from welding and cutting to forming and machining. This operates as an added bonus to our clients because it limits their need to have to hire people from multiple

vendors and through different services.

Metal fabrication can be described as building metal structures through cutting, bending and various assembling processes. Based on engineering sketches, a certain amount of money will be put forth in the form of a bid, and the fab shop that wins the contract will bid and produce it.

A metal fabrication job typically begins with engineer drawings that include precise measurements. After determining what’s being built, we move to the fabrication stage and then to the installation. Projects can range from loose parts to structural frames for buildings.

Cutting can be done in the following various ways: chiseling, shearing, sawing, torching, and numerical control. Bending, on the other hand, is done by one of two methods: hammering or with press brak

es and similar tools. Most modern-day metal fabricators use the latter option as it is seen as a more efficient way to bend metal sheets into place.

Assembling is typically done through one of the following ways: welding, binding, adhesives, threaded fasteners or riveting. For each method, both human labour and automation are commonly used. Although the end products in common types of metal work such as machining and forging are similar in functionality and shape, these

processes are not considered metal fabrication.

Impellers

Impellers are vital for the functionality of many objects, or are the perfect option for helping you pump liquids. At Bormill Inc., we take our vast, professional knowledge and combine it with state of the art impellers to cater the industrial milling industry. We have over 10,000 square feet of manufacturing space, and an overhead crane lift capacity is 12 tons.

Impellers are rotors that work to increase or decrease the amount of pressure or flow of a given liquid. Impellers can be made with a variety of materials, including iron, steel, bronze, brass and more. In the case that it is crafted out of cast material, however, it is usually referred to as just a rotor.

Impellers are the rotating part of a centrifugal pump, and are used in things such a

s agitated tanks, waterjets, washing machines and more. They work by creating enough pressure to accelerate a fluid outwards and away from the centre of rotation.

Impellers are very similar to propellers, and the two are often used interchangeably. However, the two are actually used for different purposes. Propellers, on one hand, are usually used to move an object like a ship forward, where impellers are used to move a substance, like water or gas.

Large Shafts

Shafts are an important component in engineering. Bormill Incorporated has a fully functional workshop equipped with large shafts designed to complete each mechanical engineering job in a swift manner.

Shafts are rotating machine elements that passes power from one part to another, or from one machine to another one. Most shafts can be classified into two different types: transmission shafts and machine shafts.

Transmission shafts are usually used to transfer power from the source of the power to the machine absorbing the power, and machine shafts are instead the primary part of a machine itself. Both types of shafts are made out of mild steel, however can be made out of nickel, nickel-chromium or chromium-vanadium steel if more strength is required.

The standardized length of shafts are 5 metres, 6 metres, and 7 metres. The majority of shafts come equipped with pulleys and gears mounted on them to make them more customizable to any project. Throughout history, shafts have been usually formed through hot rolling. To finish them to size, they are controlled by cold drawing, t

urning or grinding.

In civil engineering, shafts are your go-to method of drilling into the underground. In this context they are used as an underground vertical or inclined passageway for a few reasons: to build a tunnel, for ventilation, a sewerage, or for access to an underground structure.

Pumps

A pump is a device that is used to move fluids such as water or gas from one point to the next by mechanical action. There are three groups that most pumps can be categorized into, according to how to they move liquids. The three categories are: direct life, displacement, and gravity pumps.

Mechanical pumps work to serve a large range of purposes, from pumping water from wells, to pond filtering, or though aeriation. They also serve a great duty to the car industry for in terms of water-cooling, fuel injection and pumping oil.

Aside from the car industry, mechanical pumps can also be used in the medical industry. Naturally, this is not Bormill Inc.’s forte, but you can also find pumps be used for biochemical processes in making or manufacturing various medicines. They can also play a major part in the artificial replacement of body parts.

Pumps consume energy for the purpose of mechanical work through moving fluids through a system. They can have multiple energy sources, such as through electricity, manual operation or wind power. Pumps can be defined by their method of displacement. There are two different “basic” types of pumps: positive Displacement and Centrifugal.

At Bormill Inc., our modern workshops are fully equipped to top of the line pumps. Regardless of whether your project is big or small, we are confident that we have the space and materials to get your job done properly and in a time sensitive approach.

Industrial Rollers

At Bormill Inc., our clients will be happy to find a wide range of rollers that can be used specifically to get whatever mechanical engineering job you have finished. Rollers are an element of a machine that is used to hold relative motion of liquid or air, and reduce the friction between moving parts. Rollers come in a wide range of styles, including: cylindrical, spherical, gear, tapered, and needle.

A cylindered roller is a very common roller that is earliest known dating all the way back to 40 BC. Its inner and outer races are crafted to be misaligned. Spherical rollers contain an outer ring with a spherical shape, hence its name. Gear bearings are bearings that are combined to epicyclical gear, where the widths of the rollers and gearwheels are the same. A tapered roller runs on conical races, and can generally carry higher loads than ball bearings. Lastly, needle rollers are long and thin, and usually both ends of the rollers are tapered to points.

Regardless of the type, most rollers are designed to provide free linear movement on a fixed axis, or are used to prevent the motion by having an element of control over the forces that have something to do with the mobility of the moving parts.

To reduce the fraction down to a mum, the use of lubrication is often necessary. Another way that is commonly used to prevent fiction is with circular cross sections that are placed between the races of a roller’s assembly.

Tube Sheets

Tube sheets are typically composed from a flat and round piece of plate. They are primarily used to hold into place or isolate tubes in heat chambers or boilers. Tubes are attached to tube sheets by either hydraulic pressure or with a roller expansion.

Typically, tube sheets are covered with a good layer of cladding material that offers a level of support from corrosion, and can also operate as a insulator. A tube sheet made out of low carbon steel may include an additional layer of a higher alloy metal to give more resistance to corrosion. If included, the metal is bonded to the surface. Because of the protection it provides, an added layer of metal is a great way to keep costs down.

Tube sheets used for supporting elements in heat exchangers and boilers are among one of the most commonly known uses. For this specific purpose, tube sheets for exchangers and boilers are frequently made from a dense arrangement of thin-walled tubes. These tubes are inside an closed off tubular shell, and the tubes are supported by supported the sheets. In this particular situation, the tube sheets are dripped in a pattern that allows for the tube ends to pass through it.

When it is crucial to make sure that fluids do not intermix, double tube sheets are usually recommended. The inner parts of these tubes are vented to keep current with the atmosphere so that any fluid leak is quickly and easily detected.

At Bormill Inc., we have the experience and expertise to manufacture replacement parts for a wide range of industrial companies, including those that need an extra tube sheet.
