Surface roughness describes the fine irregularities of a machined surface and is usually given as Ra, the arithmetic mean roughness in micrometres (µm). It affects how parts fit, slide, seal, wear and look —...
7075 aluminium (EN AW-7075) is one of the strongest aluminium alloys available. Alloyed mainly with zinc, magnesium and copper and heat-treated to the T6 condition, it reaches tensile strengths of over 500 MPa —...
Mechanical mechanisms are assemblies of parts — such as screws, belts, gears, cams, linkages, pulleys and flywheels — that convert one type of motion into another or transmit and amplify force in a controlled,...
Metal hardness is a material's resistance to permanent indentation and wear. It determines how a part performs in use — and how difficult it is to machine. Hardness is measured with standardised tests such...
Sheet metal shearing — also called shear cutting — is a cold cutting process that separates sheet metal along a straight line between two blades, without heat, chips or kerf. It is the fastest...
CNC machining tolerances define how far a machined dimension may deviate from its nominal value — for example 50 ±0.1 mm. They decide whether parts fit together and function, and they have a direct...
PP, ABS and nylon are three of the most widely used engineering plastics — but they behave very differently. In short: PP (polypropylene) is the lightest, most affordable and most chemical-resistant; ABS is tough,...
A technical drawing is the language engineers and manufacturers use to describe a part completely: its shape, dimensions, tolerances, material and surface requirements. Anyone who designs, buys, machines or inspects parts needs to read...
A good sheet metal design guide starts with the drawing. Precise, well-structured sheet metal drawings tell the manufacturer exactly which dimensions, tolerances, materials and edge conditions matter, and they prevent costly errors, rework and...
