Parallels & systems
Parallels are used to align, level, and secure workpieces, such as in a machine vice or on a machine table. The norelem range offers parallel blocks pairs in different sizes, as well as complete parallel block sets for use on small to medium-sized devices.

Parallels: accurate, time saving and efficient
Precision on the machine table is essential for producing flawless workpieces. Unintentional deviations can lead to dimensional errors, poor fits or even render the workpiece unusable. The correct devices are required to ensure that work is carried out reliably. Parallels should not only ensure the correct positioning of the workpiece, but also prevent damage to the machine table and ensure stable clamping.
The combination of professional machining and the use of high-quality tools results in an impeccable end product. This is exactly where parallels come into play.
What are parallels?
Parallels are rectangular metal blocks that are used in machining operations to align, adjust and hold workpieces in a e.g. machine vice or on a machine table. They raise workpieces off the machine table while keeping the workpiece parallel to the table surface. A set of parallels in a wooden box is recommended to ensure that the correct height is available for any machining operation.
What makes parallels special:
- Precisely ground metal blocks
- Ensure exact alignment and fixation of workpieces
- Equalise height differences
- Protect the machine table
- Safe machining even with thin workpieces
Why are precise parallels essential?
High-quality parallels are crucial when machining a workpiece. Because only if each parallel is correctly and precisely ground can it fulfil its function and position the vice exactly parallel to the machining plane.
The key advantages at a glance:
- Dimensional accuracy during workpiece machining
- Stable support in a vice or on a machine table
- Protects and therefore extends the service life of work devices
- Less waste and reworking

Challenges without high-quality parallels
Machining workpieces using inferior, worn or even without parallels causes a series of difficulties and problems. For example, setting up the machines takes longer when no parallels are used. An uneven clamping surface can also lead to dimensional deviations, which can reduce the quality of the end product and ultimately render it unusable. If workpieces are positioned at an angle, vibrations can occur during machining, which increases tool wear and results in a poor surface finish.
In addition, damage to the machine table can occur if workpieces are positioned without parallels or are poorly clamped. Non-hardened parallels also wear out quickly, leading to constant new purchases. In the long term, this all leads to a higher reject rate, lower productivity, additional reworking and higher costs, which is why a one-off investment in high-quality parallels is more than sensible.
Advantages of high-quality parallels from norelem
From norelem, you receive parallels that are characterised by particularly high quality and manufacturing accuracy. They precisely match the specified dimensions and are case-hardened and ground. The norelem range includes various sizes of parallel pairs as well as complete sets of parallels for use on small to mid-sized fixtures. In this way, we ensure that the correct parallels are available for every application. By ensuring the high quality of the parallels, machining processes benefit from noticeable time savings and stable and precise support. This ensures consistently high results.
A set of parallels in a wooden box has the great advantage that different heights and thicknesses are available to be used flexibly as required. This means workpieces can be aligned at the appropriate positioning angle during machining. This not only leads to precise dimensions, but also to a longer service life for tools and machines, as the loads are correctly distributed even for different applications and different sizes.
Overview of the advantages of parallels from the norelem range:
- High quality with case-hardened and ground versions
- Exact dimensional accuracy for precise results
- Available as parallel pairs in various sizes or as complete sets
- Flexible use through different heights and thicknesses
- Stable support for consistently high machining quality thanks to wear resistance
For which applications are parallels suitable?
Parallels are used in almost all fields of metal and woodworking. Parallels are used above all when milling and clamping workpieces in vertical lathes, milling machines or vices, but also in metrology to check the perpendicularity and parallelism of machined parts. They are also suitable for assembly fixtures and series production or any situation in which workpieces need to be brought to a defined height.
Choosing the correct set of parallels
To make the right decision when selecting parallels, several factors should be taken into account. First and foremost, the quality of the product should be checked, paying attention to product features such as "hardened" and "ground", as this is unlikely to be the case with inferior products.
Different sizes are required for each situation. A set with different heights and thicknesses enables flexible adaptation to different workpieces. Anyone who regularly works with different components will benefit from the wide selection available in a set of parallels. If only parallels for a very specific production process is required, you can search for the correct sizes for that application.
Compatibility with other work utensils should also be taken into account. The width of the workpiece and the width of the vice are decisive here. Parallels should be about as wide as the workpiece and the vice to ensure stability. In addition to the width, the desired machining height is also important. Care should be taken to ensure that the parallels allow sufficient space for the required tool.
Finally, it is worth taking a look at the economic feasibility. A high-quality set is a long-term investment that pays off in terms of time savings, neat work and flawless end products.
