We share information and tips we’ve learned from our experience in the CNC machining and sheet metal fabrication industry.
CNC turning is one of the most widely used subtractive manufacturing processes for producing round, cylindrical, tapered, threaded, and internally bored components. In a basic turning operation, the workpiece rotates while a cutting tool follows a programmed path to remove material. This motion makes the process especially efficient for parts organized around a central axis, […]
CNC milling is one of the most widely used subtractive manufacturing processes for producing accurate metal and plastic components. It combines computer-controlled machine movement with rotating cutting tools that remove material from a fixed workpiece. Engineers use it for simple plates, housings, brackets, molds, prototypes, and complex multi-surface parts. However, choosing CNC milling is not […]
Contour milling is one of the most frequently used CNC milling strategies for producing the outside shape, internal boundary, stepped sidewall, or flowing three-dimensional surface of a machined component. Although the term may sound like a single cutting operation, it covers several toolpath styles, from a basic 2D profile around a plate to simultaneous multi-axis […]
Shoulder milling is a CNC milling operation used to produce a flat bottom surface and an adjoining vertical wall, normally forming a nominal 90-degree step. It appears in brackets, machine bases, housings, tooling plates, structural components, molds, and many other parts that need accurate locating faces or stepped geometry. Although the feature looks simple on […]
A deep pocket is a recessed internal feature whose depth makes tool access, rigidity, cooling, and chip removal significantly more difficult than in ordinary pocket milling. It appears in lightweight structural parts, housings, molds, fluid-control bodies, fixtures, and many other machined components where material must be removed without opening the feature through the opposite side. […]
An O-ring groove may look like a simple circular recess, yet its dimensions determine whether a seal compresses correctly, stays in position, and survives pressure, temperature changes, assembly, and repeated motion. A groove that is too shallow can over-compress the elastomer, while one that is too deep may not create enough contact pressure. Width, corner […]
An open slot is a common feature in CNC-machined brackets, plates, housings, clamps, and structural parts. Although it looks like a simple channel, its width, depth, end condition, tool access, and nearby wall thickness can strongly affect machining accuracy and cost. Open slots may provide adjustment, guidance, clearance, side access, or controlled flexibility. This guide […]
A dovetail slot is a trapezoid-shaped internal groove used when a part needs a sliding, locking, or alignment feature that resists pull-out better than a straight slot. In CNC machining, this feature is often small in appearance but important in function because its angled sidewalls control how another component slides, locates, clamps, or holds position. […]
A keyway is a narrow machined recess that helps connect a rotating shaft with a hub, gear, pulley, coupling, or similar component. Although the geometry appears simple, its width, depth, alignment, corner condition, and fit directly influence torque transfer, assembly, backlash, and service life. A keyway may be produced on the outside of a shaft […]
Threads are among the most common functional features on CNC machined parts, yet the phrase “types of threads” can refer to several different classifications. A designer may mean metric versus Unified sizes, V-shaped versus trapezoidal profiles, internal versus external threads, straight versus tapered pipe threads, or right-hand versus left-hand rotation. Each choice affects load direction, […]
Brushed metal and maraging steel are often searched together by buyers evaluating premium CNC machined parts, but they describe two different decisions. Brushed metal refers to a directional surface texture created on a metallic substrate, while maraging steel is a family of low-carbon, nickel-rich, age-hardenable steels. A CNC project may use maraging steel as the […]
An idler gear part looks simple from the outside, but it often controls the reliability of a whole gear train. It sits between a driving gear and a driven gear, helping transfer rotation, change output direction, or maintain shaft spacing when two main gears cannot mesh directly. For replacement projects, small machines, automation equipment, motors, […]
