INSIZE M5

INSIZE is a metrology brand that produces dimensional measurement instruments and accessories, including calipers, micrometers, indicators, height gauges, and coordinate measuring machine (CMM) styli. The company was founded in 1993 and has since established a global presence, with products distributed in numerous countries. INSIZE manufacturing facilities are certified to ISO 9001, and the brand is known for offering a broad range of measurement tools that balance cost and performance for industrial quality control. The M5 series of CMM styli is part of INSIZE's accessory line for touch-probe measurement systems. These styli are designed to interface with M5-threaded probe heads, which are a common standard in coordinate measuring machines. The M5 styli family includes straight and stepped configurations, with ruby ball tips in various diameters. Ruby is a widely used material for styli tips due to its hardness and resistance to wear, which helps maintain measurement accuracy over repeated contact with workpiece surfaces. The straight styli are intended for general-purpose probing, while stepped styli provide extended reach for inspecting recessed or offset features. Ball diameters in the M5 line range from 0.039 in to 0.315 in, covering a variety of feature sizes and probe tip requirements. The stem thread size is M5, ensuring compatibility with a broad range of CMM probe heads and extensions. Each stylus is identified by a manufacturer part number, and specifications such as ball diameter and type are clearly defined. 3G Electric supplies the INSIZE M5 CMM styli line to customers worldwide. The product range includes straight and stepped styli with ruby ball tips in multiple diameters. 3G Electric provides access to datasheets and logistics support for these items, facilitating procurement for maintenance, quality, and engineering teams. The styli are used in industries such as automotive, aerospace, mold and die, and general manufacturing, where precise dimensional inspection is required. By offering the INSIZE M5 series, 3G Electric supports the ongoing need for reliable CMM probing accessories. The styli are available for order through 3G Electric's global distribution network, with shipping options to various regions. For technical buyers, the key considerations when selecting a stylus include ball diameter, stem length, and type (straight or stepped), all of which are specified in the product data. 3G Electric can assist with identifying the appropriate stylus based on these parameters. The INSIZE M5 styli are manufactured to standard metrology tolerances, ensuring interchangeability and consistent performance. This makes them suitable for both new installations and replacement needs. 3G Electric maintains inventory and provides quotation services for the INSIZE M5 line, enabling customers to source these components efficiently. The combination of INSIZE's metrology expertise and 3G Electric's distribution capabilities offers a practical solution for CMM stylus requirements.

Frequently asked questions

Common questions about INSIZE M5 from 3G Electric.

What is the difference between straight and stepped INSIZE M5 CMM styli?

Straight INSIZE M5 styli have a straight shaft from the M5 thread to the ruby ball tip, suitable for general-purpose probing where the feature is directly accessible. Stepped styli, such as SKU 822K62 and 822K65, have a reduced-diameter section near the tip, allowing extended reach into recessed or offset features without the shaft contacting the workpiece. Both types use M5 stem threads and ruby ball tips. Selection depends on the geometry of the feature being measured and the accessibility of the probe.

What ruby ball tip diameters are available in the INSIZE M5 stylus line?

The INSIZE M5 stylus line includes ruby ball tip diameters of 0.039 in, 0.059 in, 0.079 in, 0.118 in, 0.197 in, 0.236 in, and 0.315 in. These correspond to specific manufacturer part numbers, such as ISQ-01-5010-032STR for 0.039 in and ISQ-01-5080-115STR for 0.315 in. The appropriate diameter depends on the size of the features to be measured and the probing strategy. Smaller balls are used for fine details, while larger balls provide more contact area and are less sensitive to surface finish variations.

Are INSIZE M5 styli compatible with all CMM probe heads?

INSIZE M5 styli feature an M5 stem thread, which is a standard interface for many CMM probe heads and extensions. However, compatibility depends on the specific probe head model and its thread specification. It is advisable to verify that the probe head accepts M5 threads. Additionally, the stylus length and ball diameter must be within the probe's measuring range and weight limits. For specific compatibility questions, consult the probe head documentation or contact 3G Electric for assistance.

What materials are used in INSIZE M5 CMM styli?

INSIZE M5 CMM styli use ruby balls for the tip, which is a synthetic corundum material known for high hardness and wear resistance. The stem is typically made of stainless steel or a similar rigid material, providing dimensional stability. The M5 thread is machined into the stem base. Ruby is chosen because it resists adhesive wear and maintains sphericity over many measurement cycles. These material choices are standard in metrology styli and contribute to consistent touch-probe performance.

How do I select the correct INSIZE M5 stylus for my application?

Selection involves matching the stylus to the feature being measured and the CMM probe head. Consider the ball diameter: smaller balls for small features, larger balls for general use. Determine if a straight or stepped stylus is needed based on accessibility. Check the overall length to ensure it reaches the feature without collision. Verify that the M5 thread matches the probe head. INSIZE provides part numbers for each configuration, and 3G Electric can supply datasheets to aid selection. For complex applications, consult metrology guidelines or contact 3G Electric for support.

What is the role of the M5 thread in INSIZE styli?

The M5 thread is the connection interface between the stylus and the CMM probe head or extension. It is a metric thread with a 5 mm nominal diameter, commonly used in metrology for its balance of rigidity and size. INSIZE M5 styli are designed to screw directly into compatible probe heads, allowing quick changes and secure mounting. The thread ensures repeatable positioning and transmission of contact forces to the probe sensor. When ordering, confirm that the probe head has an M5 female thread.
