Product Guide
Application Scenarios+
Close-space punches are used when the die set has limited clearance and hole/forming features must be driven accurately from a compact tool stack. These punches are well-suited for fine-pitch automotive connector and terminal slot punching, where the surrounding die walls restrict punch-to-die movement and tool geometry must remain stable during repeated cycles.
In appliance and small hardware bracket dies, the compact profile helps maintain consistent forming in confined layouts, supporting predictable part dimensions and reducing the risk of misalignment-related defects.
The metric variant with XVP coating is especially helpful for long run production: the coating improves surface protection against sliding wear at the punch tip and shank bearing areas, helping maintain punch performance over higher cycle counts.
- Use in tight die cavities requiring close clearance and controlled punch seating
- Pairs well with metric press and die builds where shank diameters must match standard tooling
- Targets reliable forming and hole punching with improved wear endurance
Material & Process Details+
The provided specifications identify this as a metric close-space punch line with an XVP coating, intended to improve wear behavior during punching and forming. While the exact steel grade and heat-treatment parameters are not specified in the available metadata, the coating’s role is to enhance surface durability where abrasive wear and tool-to-material friction are highest.
For close-space punch performance, engineers typically consider a balance of hardness for wear resistance and toughness for edge stability to resist chipping under impact loading. Common practice for similar coated punch tooling is to use a through-hardened or quenched-and-tempered base steel, followed by coating application; however, the specific base condition and hardness (HRC) cannot be confirmed from the data provided.
- XVP coating: designed to support longer tool life under repeated cycles
- Trade-off: higher hardness improves wear resistance but can reduce toughness if not properly tempered
- Base steel/heat treatment: not listed in the provided specs
Sizing & Selection Guide+
Select the punch by matching the shank diameter (D) and the operating P dimension range to your die assembly and clearance conditions. Available shank diameters are D = 02, 03, 04, 05, 06, 07 mm, so choose the diameter that fits your metric guide/bushing and supports stable guidance in the close-space cavity.
The length (L) is fixed across the line at 40 ～ 100 mm. Choose L to ensure adequate stick-out and support through the die stack while avoiding insufficient engagement or interference with upper/lower tooling.
For seating and forming geometry, use the P dimension, which is specified as 0.8 ~ 6.01 mm. Keep P consistent with the required punch penetration/working projection in the cavity design, and verify tool-to-die clearance for close-space builds.
- Configurable: D (from 02 to 07 mm), L (40–100 mm), P (0.8–6.01 mm)
- Fixed: the line’s core configuration is a close-space punch with the listed P dimension options
- Tolerances: not provided—confirm fit with your die guide/bushing specs and tooling drawings
Frequently Asked Questions
Which shank diameter options (D) are available for this close-space metric punch?+
The available D (shank diameter) options are 02, 03, 04, 05, 06, 07 mm. Choose the diameter that matches your metric guide or die support features to maintain stable punch guidance in tight die spaces.
How do I choose the correct P dimension when designing a close-space die cavity?+
The P dimension is specified as 0.8 ~ 6.01 mm. Select P based on the required working projection/penetration geometry in the cavity so the punch achieves consistent hole/forming results without causing interference in the limited clearance zone.
Is the length (L) fixed or configurable, and what range is offered?+
The product specification provides a fixed L (Length) range of 40 ～ 100 mm. Use L to balance adequate tool engagement through the die stack with avoidance of upper/lower interference during cycling.
What does the XVP coating contribute for repeated punching cycles in confined tooling?+
This punch line includes XVP coating, which is intended to provide wear resistance and support longer service life under repeated cycles. In close-space tooling, coating helps protect high-friction surfaces where wear can quickly degrade forming performance.
What tolerances should I verify for fit when using different D and P values in a metric die build?+
The provided metadata lists D and P ranges but does not specify tolerances. For correct fit in close-space assemblies, confirm your guide/bushing and assembly clearances against the punch’s drawing/spec and your tooling requirements, since tolerances are critical for seating and alignment.
