Product Guide
Application Scenarios+
Close-space straight punches are used when die positioning accuracy is required but available clearance is limited. In stamping and punching die sets, the straight punch geometry supports consistent alignment of the punch to the die opening, helping reduce misregistration during repeated press cycles.
The XNM-coated variant is especially suited for high-cycle production runs where sliding contact and frequent tool engagement elevate wear. In close-tolerance forming processes, the punch face and guide surfaces benefit from improved wear performance, which helps maintain dimensional stability over time.
- Tight-clearance die alignment: minimizes lateral play using a straight, metric punch format.
- Automated or high-volume presses: coating durability supports longer service life under repetitive cycles.
- Metric die tooling: standardized punch formats integrate with typical metric die systems.
Material & Process Details+
The provided product specifications focus on geometry and XNM surface treatment, but no steel grade, heat-treatment state, or hardness (HRC) is explicitly listed in the data. For accurate material selection, confirm the tool steel grade and heat treatment from the manufacturer’s technical documentation for series code 250301353980.
That said, the XNM coating is chosen to improve wear resistance in repetitive press cycles where metal-to-metal contact and sliding conditions are severe. In practice, coatings trade slightly increased brittleness risk at the surface for improved abrasion resistance and reduced frictional wear.
- Coating-driven wear control: extended run time by lowering surface wear rates.
- Hardness/toughness balance: depends on the underlying steel’s quenched & tempered or similar heat treatment (not specified here).
- Multiple head types: angled head (AWX) and regular head (AXX) affect contact/guide behavior more than base material in this dataset.
Sizing & Selection Guide+
To select the correct close-space straight punch, match the L (Length) and the guide contact dimension P to your die set design. The fixed length range is L = 40 to 100 mm, and the fixed P dimension range is P = 0.8 to 7 mm.
- Match L to tooling stack-up: choose a length that provides the required engagement and guidance for your press stroke and die shut height without bottoming.
- Match P to clearance/close-space needs: select the P value that aligns with the intended close tolerance die positioning interface.
- Consider head type impact: use Regular head (AXX) or Angled head (AWX) based on how the punch enters/locates in your tooling.
Tolerance and fit requirements depend on your die steel, wear allowances, and the specific guiding interface. Because specific tolerance grades are not provided in this dataset, verify your target clearance (side play) and any regrind allowances against your standard die design tolerances before final selection.
Frequently Asked Questions
Which dimensions are fixed for this close-space straight punch series, and how do I choose them?+
For series 250301353980, the fixed ranges are L (Length) = 40 to 100 mm and P = 0.8 to 7 mm. Choose L to match your die stack-up and required engagement, and choose P to fit the close-space guiding interface in your die cavity/core layout.
When should I select the angled head (AWX) versus the regular head (AXX) for die positioning?+
This series lists two head configurations: Angled head (AWX) and Regular head (AXX). Select the angled head when your tooling benefits from an angled approach or entry geometry; select the regular head when you need a more straightforward guide profile for consistent alignment.
What role does the XNM coating play in wear and service life for punching tools?+
The data specifies an XNM surface treatment intended to improve wear performance under repetitive press cycles. In high-cycle stamping and close-tolerance forming, reduced surface wear helps maintain alignment characteristics for longer intervals.
Is there enough information here to determine hardness (HRC) and heat treatment of the steel?+
No—this dataset does not provide the steel grade, hardness (HRC), or heat-treatment state (e.g., quenched & tempered, nitrided). To confirm hardness and toughness trade-offs for your application, request the steel/material certificate for series 250301353980.
How do I ensure the punch will integrate with a metric die system?+
The product description indicates suitability for metric die systems using standardized punch formats. When integrating into your die set, verify that your cavity/core positioning and the required engagement lengths correspond to the selectable L = 40–100 mm and the close-space interface defined by P = 0.8–7 mm.
