A cylinder machine, or boring bar, is used to remove nicks and create a straight cylinder wall in an engine block. It can also ream the block for a replacement cylinder sleeve. The machine bores the cylinder to a larger size to remove depressions caused by piston wobble and piston ring wear. Final sizing is […]
A continuous casting machine is used to cast molten metal in a continuous stream, commonly with steel and copper. Metal is placed in a ladle, then poured into a tundish, cooled, and shaped by rollers. The machine can only produce simple shapes, and other machines are often used to further shape the metal. A continuous […]
Machine tools are powered tools that make parts for other machines. They remove material to produce the desired piece through cutting and feed. Milling, turning, drilling are types of machine tool technology that differ in the method used to remove material. Before we can discuss the different types of machine tool technology, we first need […]
A forging machine presses metal into a specific shape using cold, warm, or hot temperatures. Forged parts are stronger than cast or machined parts due to the grain of the material flowing in the same direction. Cold forging is used on smaller parts, while hot forging involves stamping red-hot metal into a basic shape. A […]
Paper machines, based on the Fourdrinier machine, are used to make paper. They consist of four sections: the wet end, press section, dryer section, and calendar section. Different configurations are used to create papers of different qualities. The machine is supplied with a slurry of wood pulp and water, and the paper is shaped into […]
The Z Machine generates extreme temperatures and X-rays to study nuclear fusion. It can fuse light nuclei, potentially leading to aneutronic fusion. Originally designed to deliver 50 terawatts, it now delivers 290 terawatts. The electric discharge created is so massive that sparks leap from every metal object in the room. The Z Machine is a […]
Hero of Alexandria was a 1st century AD mathematician, engineer, and inventor who created many mechanical inventions, including the first steam-powered device and vending machine. He was a follower of Ctesibius and his calculations, Heron’s algorithm and formula, are still used today. Hero of Alexandria – also known as Heron of Alexandria – was a […]
The Gatling Gun, invented by Richard Jordan Gatling in 1862, was an early machine gun with multiple rotating barrels capable of firing 3,000 rounds per minute. It was replaced by more sophisticated designs but the multi-barrel design is still used in anti-aircraft weapons and vehicle-mounted artillery. The invention was made possible by the development of […]
Manual milling machines and hand routers are material cutting devices that require skilled operators. They can cut material horizontally or vertically and are ideal for small-scale jobs. Automated milling machines replaced manual versions in the 1940s, but hand routers are still used by small businesses and independent individuals. Some hand milling machines have a digital […]
Machine tool design involves designing and constructing machines for industrial use, such as lathes, drills, and milling machines. Key components include the frame, slides and rails, electric motors, controls, and software. The industry is expected to grow globally, with a focus on replacing outdated machines. Machine tool design involves the design, construction and construction of […]
Choosing the right CNC engraving machine involves researching its specifications, workload capacity, maintenance requirements, and size. It’s important to consider future projects and available space. Maintenance costs and customer support should also be taken into account. Choosing the best CNC engraving machine involves researching whether its specifications match your project needs, the amount of work […]
Choosing the right machine screw involves considering factors such as length, thickness, material, and head shape. The screw should be long enough and thick enough to hold the pieces together, and the material should be chosen based on strength and durability. The head shape should match the tool used, and there are three different head […]
Extrusion machines create long, rod-like finished products from raw materials like aluminum or plastic. Choosing the best machine depends on the material, frequency of use, and project type. Hot and cold extrusion processes are available, as well as direct and indirect machines. Budgeting for the purchase, considering electrical requirements, and installation costs are important factors […]
Printing press operators are responsible for maintaining and operating the press, checking materials and specifications, reviewing work orders, adjusting the printer, and performing routine maintenance. They also keep records of materials produced and supplies used. A printing press operator’s primary responsibility is the proper operation and maintenance of the press. Pressing machine operators install and […]
A tomato machine can turn tomatoes into juice, paste or pulp. They come in various designs for home or commercial use, with features to remove skin and seeds. They can be electric or manual and have modular accessories. Components include a hopper, paddles, a chute, and a clamp or suction cup. Processing is done by […]
A machine tender manages the operation and maintenance of machinery to promote efficient production. They perform tasks beyond those of a machine operator, including simple maintenance, but are not responsible for advanced repairs. Proper maintenance is crucial for extending machinery life and maintaining production quality. Machine tending is a type of job position that requires […]
The Atwood machine, named after its inventor Reverend George Atwood, consists of two masses suspended by a string on a pulley and is used to demonstrate laws of motion. By applying Newton’s second law, it can be calculated that the acceleration will be constant for both masses. The machine is used to confirm and better […]
CNC machines are operated by computers and used to cut metals, plastics, and wood. Becoming a trained operator requires basic math and computer skills, and can be learned on the job or through post-secondary training. Advancement opportunities exist with additional training and experience. CNC machines are formally known as computer numerical control machines because they […]
A universal testing machine determines the quality of materials by pulling, compressing, bending, or stretching them until they break. It is mainly used by laboratories that produce or print various plastics. The machine consists of one or two vertical columns mounted on a base, with a second horizontal plate for holding the sample. The most […]
A machine operator’s resume should include contact information, job objective, work history with specific equipment used, specialist education and training, and any unusual or specialized projects. It should also mention experience with CNC machines and software used, as well as any certificates received. A cover letter can provide additional information. A machine operator resume should […]
