Before a part is machined, it must be measured, marked, and laid out. The precision engineering tools market includes the measuring and inspection tools that ensure accuracy.

Measuring and Inspection Tools

The [LSI keyword: precision engineering tools market] for "measuring" includes: calipers (digital, dial, vernier) for external and internal dimensions. The market for "digital" calipers is the largest. Micrometers (outside, inside, depth) for finer measurements. The market for "digital" micrometers is growing. Height gauges for measuring heights from a reference surface. Dial indicators and test indicators for measuring runout, flatness, and parallelism. Bore gauges for measuring internal diameters. Surface roughness testers for measuring surface finish. The market for "portable" roughness testers is growing. Coordinate measuring machines (CMMs) for 3D measurements of complex parts. The market for "shop-floor" CMMs (less sensitive to temperature and vibration) is growing. Vision measurement systems for measuring small parts and features (e.g., circuit boards, micro-molds). The market for "optical" comparators is a traditional alternative.

The precision engineering tools market for "inspection" includes: go/no-go gauges (plugs, rings, snap gauges) for pass/fail testing. Thread gauges for inspecting threads. The market for "hard" gauges is mature. The market for "digital" gauges (with electronic readouts and data output) is growing. The market for "calibration" services (ensuring that measuring tools are accurate) is a related aftermarket.

Layout and Marking Tools

The precision engineering tools market for "layout" includes: surface plates (flat granite or cast iron) as a reference plane. The market for "granite" surface plates is the largest. Scribers and dividers for marking lines. Center punches for marking hole locations. Angle plates and squares for setting up workpieces. V-blocks for holding round stock. The market for "precision" squares (engineer's squares) is a standard.

As the precision engineering tools market continues to evolve, the focus will be on "wireless" data transmission (from calipers and micrometers to a computer), on "smart" gauges (with built-in data logging), and on "automated" inspection (using robots to position parts on CMMs). The micrometer precision level segment is the largest . The precision engineering tools market is the quality assurance department of the machine shop, ensuring that parts meet specifications before they are shipped.
