INSIZE M3

INSIZE is a manufacturer of precision measuring instruments and metrology accessories, with a product range that includes calipers, micrometers, indicators, and coordinate measuring machine (CMM) styli. The company was established in 1993 and has since developed a global distribution network, serving industries that require dimensional inspection and quality control. INSIZE products are commonly used in machining, automotive, aerospace, and electronics manufacturing, where accurate measurement of part features is critical. The INSIZE M3 line of CMM styli is designed for use with M3-threaded touch probes on coordinate measuring machines. These styli feature ruby ball tips, a material chosen for its wear resistance and low thermal expansion, which helps maintain measurement consistency over repeated contact with workpiece surfaces. The M3 styli are available in straight and stepped configurations, with ball diameters ranging from 0.02 in to 0.157 in. The M3 stem thread size is a standard interface for many CMM probes, allowing these styli to be used across a variety of metrology systems. 3G Electric supplies the INSIZE M3 CMM styli line, offering 24 SKUs that cover multiple ball diameters and configurations. The product range includes straight ball styli and stepped styli for extended reach applications. Each stylus is identified by a manufacturer part number, such as ISQ-01-3015-030TTR or ISQ-30-031, which can be used to cross-reference specifications. The styli are intended for dimensional inspection tasks, including checking machined parts, tooling, and molded components. In quality control environments, the choice of stylus depends on the feature being measured: smaller ball diameters are used for accessing tight spaces or small holes, while larger balls provide more contact area for stable measurements on rough surfaces. Stepped styli allow the probe to reach deeper into bores or recesses without the stem contacting the workpiece. 3G Electric supports the INSIZE M3 line by maintaining inventory of these styli and providing technical specifications to help buyers select the appropriate part number. The company serves a global customer base, shipping to industrial facilities, machine shops, and metrology laboratories. For procurement specialists and maintenance managers, 3G Electric offers a centralized source for INSIZE M3 styli, reducing the need to source from multiple suppliers. The product data includes ball tip diameter, stem thread size, and manufacturer part number, enabling accurate replacement or upgrades to existing CMM setups. This focus on specification-driven supply aligns with the needs of technical buyers who require verifiable part details for their measurement systems.

Frequently asked questions

Common questions about INSIZE M3 from 3G Electric.

What is the difference between straight and stepped INSIZE M3 CMM styli?

Straight INSIZE M3 styli have a direct stem-to-ball geometry, suitable for most standard probing tasks where the feature is accessible. Stepped styli, such as SKU 822K25, incorporate a step in the stem that allows the ball to reach deeper into bores or recesses while keeping the stem clear of the workpiece. The step effectively extends the reach without increasing the overall length of the stylus, which can help maintain rigidity. Selection depends on the geometry of the feature being measured and the clearance available around the probe.

What ball tip diameters are available in the INSIZE M3 stylus range?

The INSIZE M3 stylus line includes ruby ball tips with diameters from 0.02 in to 0.157 in. Specific sizes in the 3G Electric catalog include 0.02 in (SKU 822K25), 0.059 in (SKUs 822K30, 822K31), 0.08 in (SKU 822KC9), 0.118 in (SKUs 822K41, 822K35, 822K42), and 0.157 in (SKU 822K37). Smaller balls are used for accessing tight features, while larger balls provide more contact area for stable measurements on uneven surfaces. The appropriate diameter depends on the feature size and the probing force of the CMM.

Are INSIZE M3 styli compatible with all CMM touch probes?

INSIZE M3 styli have an M3 stem thread, which is a common interface for many CMM touch probes. However, compatibility depends on the specific probe model and its stylus mounting requirements. Users should verify that their probe accepts M3-threaded styli and that the stylus length and weight are within the probe's specifications. The manufacturer part numbers, such as ISQ-01-3030-050TCR, can be used to cross-reference with probe manufacturer guidelines. 3G Electric provides these part numbers to assist with verification.

What is the advantage of a ruby ball tip on INSIZE M3 styli?

Ruby (synthetic sapphire) is used for CMM stylus tips because it is hard and wear-resistant, which helps maintain the ball's spherical form over many contact cycles. This reduces the need for frequent recalibration compared to softer materials. Ruby also has low thermal expansion, so temperature changes in the measurement environment have minimal effect on the ball diameter. Additionally, ruby is chemically stable and does not readily adhere to most workpiece materials, reducing the risk of material build-up that could affect measurement accuracy.

How do I select the correct INSIZE M3 stylus for my measurement application?

Selection depends on the feature being measured and the CMM's probing system. Consider the ball diameter: use a smaller ball for small holes or narrow slots, and a larger ball for rough surfaces or deep features where a larger contact area is beneficial. The stylus length and step configuration affect reach and rigidity; longer styli may require slower probing speeds. Also verify that the stylus weight is within the probe's limits. The manufacturer part numbers and specifications provided by 3G Electric can be used to match the stylus to your existing setup.
