Box Parallels for Industrial & Workshop Use — AA-2724

Box parallels are precision tools used in machining and inspection to accurately elevate and align a workpiece on a machine table, like a milling machine or surface grinder. They provide a stable, flat, and parallel surface for setting up jobs.

Crystal Box Parallels are constructed from high-density, hardened cast iron or alloy steel. This ensures excellent dimensional stability, wear resistance, and durability under heavy industrial use.

Yes, their precision-ground surfaces and high stability make them ideal for elevating workpieces during surface grinding operations, ensuring a consistent and accurate finish.

Crystal Box Parallels are manufactured to high precision standards, ensuring flatness and parallelism suitable for most industrial and workshop machining and inspection tasks.

To maintain accuracy, always clean the parallels before and after use, store them in a dry place to prevent corrosion, and avoid dropping or hitting them, which could damage the precision surfaces.

Box parallels are typically sold and used in matched pairs to ensure a perfectly level setup. Please check the product details for specific purchasing options.

Hardened materials prevent the edges and surfaces from being damaged or worn down during use, which preserves the tool's accuracy over a long service life.

The AA-2724, with its 150x100x50mm dimensions, is ideal for workshops handling small to medium-sized parts that require a stable, rectangular base for milling or inspection.

The AA-2725 is a versatile mid-range option suitable for a wide variety of general machining tasks. It's a great all-rounder for job shops that need flexibility.

The AA-2726 is a 100mm cubic block, making it perfect for setups that require a precise, square reference point for both height and width, common in inspection and tool setting.

Choose the AA-2727 for larger and heavier workpieces that demand a more substantial and stable base. It's suited for medium to heavy-duty industrial applications.

The AA-2728 is designed for heavy components that require a large, robust setup block to ensure safety and maintain accuracy during machining.

As the largest model in this series, the AA-2729 is the top choice for heavy industrial manufacturing, supporting very large and heavy parts for milling or grinding.

The primary difference is their shape and size. The AA-2724 is a rectangular block (150x100x50mm), offering different height options, while the AA-2726 is a perfect cube (100x100x100mm), providing uniform dimensions on all sides.

The model AA-2729 is the largest in the series, providing the most substantial surface area and support for the heaviest and bulkiest workpieces.

Consider the typical size and weight of the workpieces you handle. Your parallels should provide stable support without interfering with the machining operation. It's often useful to have a few different sizes to accommodate various jobs.
