Precision parallels for accurate workholding
Parallel parallels, also known as precision parallels and setup parallels, provide stable, ground reference surfaces that ensure workpieces are aligned and levelled for milling, drilling and grinding operations. Used as support and spacing blocks, they help to secure components during machining and enable quick, repeatable setup while facilitating inspection of parallelism and flatness; typical materials include hardened steel, stainless steel and carbide for long life. By offering high tolerances and finely ground surfaces, these precision parallels, setup parallels and machining parallels reduce setup time, improve dimensional accuracy and support precise tool and machine adjustments.

The flatness of 0.1 µm for the M318.226 flat glass set refers to the maximum deviation from an ideal plane across the reference face and is the basis for using the plates as high-resolution verification standards. Can the set be used directly to calibrate a micrometer? The set provides stable reference thicknesses for verification and comparative checks; the M318.226 kit is intended for inspection and verification rather than as a primary calibration artefact with accredited status unless accompanied by a separate calibration certificate. Are the plate dimensions suitable for small workshop micrometers? Yes, the plate thicknesses (40.62 – 41.00 mm) are selected to support verification tasks within the 25–50 mm micrometer range and are compact enough for typical workshop micrometer rests. What handling precautions are recommended for these glass plates? Handle the plates with clean gloves, store them in a dust-free environment, and avoid sharp knocks; the M318.226 plates are durable for inspection use but benefit from careful handling to maintain flatness. Is the parallelism of 0.006 mm significant for routine checks? Yes, a parallelism of 0.006 mm ensures that contact faces remain aligned during a check, reducing measurement uncertainty when comparing micrometer readings against the glass standards.

Take advantage of an accurately dimensioned reference set that combines 0.1 µm flatness with a compact, four‑plate layout to keep routine micrometre checks fast and reliable. The set supports verification across the 50–75 mm range and offers consistent parallelism (0.006 mm) for reproducible comparisons — order via Metav Werkzeuge or consult our team for selection advice. M318.227 plane-glass set — optical flats for micrometre inspection, 0.1 µm accuracy (Metav IndustryLine) The M318.227 plane-glass set is an optical reference kit for verifying micrometres in the 50–75 mm measuring range, supplied as four precision plates to check anvil parallelism and measuring consistency. 0.1 µm flatness for high-precision checks Four precision plates for 50–75 mm micrometres Parallelism 0.006 mm for reproducible results Total weight 0.5 kg for easy handling Reliable reference for routine micrometre verification The M318.227 set provides an economical, metrology‑grade reference for routine checks of micrometres and small measuring instruments. With a declared flatness of 0.1 µm, the plates serve as a stable, known surface against which anvil faces can be compared. This level of flatness helps to reveal wear, dirt or alignment errors that would otherwise introduce systematic measurement bias. The four plate sizes (65.62 / 65.75 / 65.87 / 66.00 mm) allow cross‑checking across a narrow band of clearances typical for the 50–75 mm micrometre class. Controlled geometry for reproducible comparisons Consistent geometry is central to reproducible verification: the set’s parallelism of 0.006 mm ensures that readings taken across different plates remain comparable. For workshop quality control this reduces scatter between checks and shortens decision cycles for maintenance or rejection. The plates’ compact design and total mass of 0.5 kg make handling straightforward while maintaining sufficient rigidity to avoid bending during short inspection routines. The result is a practical balance of stability and portability for bench‑level metrology. Micro-class suitability for fine mechanical work Classified for the Micro category (measuring range 50–75 mm), this reference kit is tailored to fine mechanical and precision‑assembly environments where space is limited and accuracy matters. The set fits the workflow of tool rooms, small‑parts assembly and repair benches, enabling quick verification without specialised fixtures. Each plate performs as a precision reference to confirm that the measuring instrument remains within its expected behaviour, supporting traceable quality procedures in small to medium production runs.

Precision alignment and stable support for exact machining
Parallels, also known as parallel blocks or parallel supports, provide reliable reference surfaces for a wide range of workshop and production tasks. Designed for aligning and levelling workpieces or machine components, they are an essential accessory in milling, drilling and grinding where parallelism and flatness are critical.
How parallels support your machining process
Parallels are used to support and stabilise workpieces during machining, to set tools and machines precisely, and to act as reference surfaces for measuring and testing. In practice they ensure a workpiece remains secure and true to the intended datum, reducing chatter and enabling consistent, repeatable results. Typical applications include clamping setups on machine vises, height setting for toolholders, and as spacers to guarantee uniform gaps between components.
Tangible advantages that improve throughput and quality
- Increased precision through tight tolerances and repeatable reference surfaces.
- Reduced setup time by using standardised sets with graduated sizes and thicknesses.
- Extended tool and workpiece life thanks to robust materials such as hardened steel, stainless steel or carbide.
- Consistent measurement results owing to ground and lapped surfaces that ensure flatness and parallelism.
- Versatile use as supports, spacers and measuring references across multiple machining operations.
