Frequently Asked Questions
28-piece parallel supports — what are they used for in the workshop?
Parallel supports (parallel blocks) are pairs of hardened and ground steel blocks with flat surfaces parallel to ±0.005 mm. They are used to: raise workpieces on the milling machine vise to the correct height, ensure that the workpiece is positioned perpendicularly to the tool, and check the flatness of surfaces. The ±0.005 mm precision ensures that the set height is repeatable across the entire series of workpieces.
How are they correctly used on the vise?
Position the parallel supports under the workpiece in the vise before tightening. After tightening, lightly tap the workpiece downwards with a plastic mallet — if the supports are loose (slide), the position is correct; if they are rigidly blocked under load, there is an irregularity in the workpiece that needs to be corrected. Never proceed with milling if the supports appear to be under asymmetric tension.
