Ball Lock Button Dies (Metric)

These metric ball-lock button dies are used in die assemblies and manufacturing fixtures where fast, repeatable clamping is required. The ball-lock retention feature helps maintain stable engagement under load, reducing the risk of drift during high-cycle operations.

• Automated assembly line tooling: Use them as quick-access die components on fixtures that require frequent setup changes. The controlled dimensional build supports reliable installation and consistent positioning.
• Press and progressive die work: Fit the button tips into corresponding pockets for repeatable location of mating parts. Tip geometry options (round, rectangle, oblong, double flatted round, radius rectangle) allow matching to the die land/pocket shape.
• General die maintenance and die spot clamping: Choose the Economy/Regular variant based on duty cycle and performance needs while keeping the fixed L = 40 mm for consistent stack height.

Overall, the secure ball-lock mechanism and configurable tip geometry make this variant suited for tooling that must maintain clamping reliability while supporting efficient maintenance.

The provided product data does not specify a steel grade, coating, or explicit heat-treatment state (e.g., quenched & tempered or nitrided). Therefore, material-property claims such as HRC, wear resistance, and toughness cannot be stated from the current specification set.

From a manufacturing/process standpoint, ball-lock button dies are typically precision ground and machined to ensure tip fit and consistent engagement. The dimensional control for D (13–38 mm) and the tip dimensions (e.g., P, W, R) indicates a need for stable geometry to achieve reliable ball-lock retention.

• Trade-off consideration: For wear-heavy duty, harder tool steels (often through quench/temper or surface hardening) can improve resistance to tip rounding, but may reduce toughness if over-hardened. Without grade data, select based on your existing die steel strategy and expected load cycles.
• Variant comparison: Regular vs. Economy is listed, but material differences are not provided—confirm with the supplier’s technical sheet if hardness or heat treatment is critical.

Selection starts with the outer diameter D (13, 16, 20, 25, 32, 38 mm). Match D to the clearance/fit of the mounting bore in your die plate or fixture to ensure the button seats without excessive play while still allowing reliable ball-lock engagement.

• Fix the overall length: Use L = 40 mm since it is fixed for this series. This controls the stack-up height and ensures the tip reaches the mating pocket depth consistently.
• Verify insertion/clearance: Choose the LC (33 ～ 39.9 mm) full-length alteration within the allowed range to match your die thickness and pocket depth. Use the LC value to avoid bottoming or insufficient engagement.
• Set the tip geometry: Select Tip shape (round/rectangle/oblong/double flatted round/radius rectangle). Then choose P (2.5 ~ 19 mm), W and corner radius R (0.15 up to the maximum range by option) so the tip profile mates with the pocket/land.

Tolerance/fit: because the series emphasizes controlled dimensional build, specify the receiving-pocket dimensions to your shop’s standards. If you operate near minimum clearance, prioritize the correct tip radius R and tip dimension alteration ranges (PC, WC) to maintain repeatable locating contact.
