Alterations

Would you like to customise our standard items or does your Dayton offer (quotation) on punches or button dies contains an „X“-parameter, the meaning or which you wish to learn?

In this case, the overview below may assist you.

Alternations enable you to adapt our standard products to your purpose. If goes without saying that these modifications are subject of certain dimension limitations, yet in many cases this service makes it possible to quote for special needs as standard catalog item.

Pleas enote that the table below is just an index of available alterations. For details on dimensions and correct applications, we invite you to contact our customer service or to consult our catalog for most issues.

Moreover, alterations contain antitwist protection mechanisms and coatings. For details, please consult the respective catalog chapters.

Coating

Whatever your company produces: by the choice of the coating you can increase productivity, life time and production time. This helps to reduce costs and to be more efficient.

The following table shows an overview of our coatings:

 

Surface Treatment

XN - DayTride®

A low-cost surface application that treats all exposed surfaces. Ideal for punches and die buttons. Provides high dimensional stability. Ultra-hard (harder than carbide). Provides superior abrasive wear resistance and lubricity. Wellsuited for stainless steel, nickel, and copper.
Approx. hardness: *Vickers 3000 Approx. hardness: RC73. "

XCR - DayKool®

Cryogenic steel conditioning process, used primarily with hard, thick materials. Improves strength, toughness, and dimensional stability. carbides provide more evenly distributed wear); less sharpening
time; no loss of resistance after sharpening; longer die runs; and less downtime. (Standard on all Dayton TuffPunch® products)

 

 

 

 

Abrasive Wear

XNT - DayTiN®

Applied via PVD (physical vapor deposition).  Provides extreme hardness (hard as carbide) and excellent lubricity when used with a lubricant.  Not recommended for stainless steel, copper, or nickel.  Approx. hardness:  *Vickers 2300.

XCN - TiCN

Very hard PVD, thin film.  Provides ultra hardness (harder than carbide) and superior abrasive wear resistance.  Approx. hardness:  *Vickers 3000.

XAN - DayTAN™


Ultra-hard, high-aluminum PVD coating. Absorbs shear stress and provides high temperature resistance. Ideal for HSLA, dual phase, and TRIP steels. Approx. hardness: *Vickers 3400.

XNA -ZertonPlus™

PVD coating with superior hardness (harder than carbide); provides superior abrasive wear resistance and excellent lubricity. Provides highest temperature resistance, thermal shock stability, & hot hardness. Approx. hardness *Vickers 3200.

 

 

Adhesive Wear

XNM

PVD, solid film.  Produces lower coefficient of friction than other coatings.  Provides excellent lubricity. Ideal for aluminum, pre-painted, and galvanized steels. Approx. hardness:  *Vickers 2000.  

XCD

PVD, solid film.  Produces lower coefficient of friction than other coatings.  Provides excellent lubricity. Ideal for aluminum, pre-painted, and galvanized steels. Approx. hardness:  *Vickers 2000.  

 

 

Extrusion Coating

XNP

The ultimate coating for extrusion and forming applications. Excellent wear resistance, superior surface finish, and high lubricity. Ideal for extruding and forming applications. Also works well in shaving operations.  Tolerance is ± .0002. Approx. hardness:  *Vickers 3100.

XNAP - XNAProgress

Ultra-hard PVD coating that absorbs shear stress; provides excellent high-temperature resistance. Ideal for stamping where tools are exposed to extreme stress profiles. A good alternative to TD coating without the dimensional changes associated with that process. Approx hardness: *Vickers 3200.

 

 

Further Coatings

CRN

Excellent adhesion, high toughness, and good corrosion resistance.  Primary applications are metal forming (copper, brass, bronze), metal die casting, and plastic injection molding.  Approx. hardness: *Vickers 1800-2100.

 

Slug Control (XSC)

Dayton Slug Control is a guaranteed method for reducing the risk of pulling slugs to the die surface during withdrawal of the punch. An exact amount of “trap” is applied to the slug to prevent it from returning to the die surface. A series of grooves is designed inside the die button (see drawing). There, the slugs are trapped until they are pushed through the relief by the next slug. The use of Dayton Slug Control has no effect on the size of the hole, and will not require any changes in current regrind practices.

This alteration works in any die button from a hole diameter ≥ 1.1 mm and maximum 10% clearance per side. Whether the die button has a counter bored hole or a tapered hole in the slug relief area. It works in shapes as well as round holes.

Using the Dayton Slug Control system reduces or eliminates the following die maker treatments:

• breaking all cut edges
• bell-mouthing die buttons
• dome or shear angles on punch points
• dulling punches
• notching punches
• entering punches deeper
• Punch breakage due to double hits
• Costly vacuum sleeves
• Die maintenance time
• Press downtime, wasted material and lost man hours

The slug control is specified by alteration XSC and needs material thickness (inches) and clearance per side for production.

 

Ball Seat

The Ball Seat specifies the location of the ball for Ball Lock punches.
The standard Ball Seat Location is at 90° and will be used when no other information is given.

Alternate locations are 0°, 180°, or 270° or any degrees counter-clockwise from 0°.

The Ball Seat location can be specified as “BS” (e.g. BS-90°)


The picture shows the order of the degree according to industry standards:

Classified shapes

We offer the following classified shapes in addition to the standard shapes. No extra CAD data needed. You just name us the shape (e.g. C21) and the needed dimensions.

All shown shapes are oriented according to our standard (see degree).

Key Flats

Key Flats are essential when shaped punches and die buttons are used. Otherwise, the designed holes will be different than planned.

For naming the needed key flat, you only have to add the code (e.g. X2) to the call out.

Here’s some facts about key flats:

• Key flats are used for headed punches and all kind of die buttons
• Key flats can be added at the head or can be go the whole length down a punch or die button.
• Standard position of a key flat is 0° (parallel to P dimension)
• Alternate locations are 90°, 180°, or 270° or any other degree based on the customers‘ whish.
• Key flats are always oriented toward the same position – starting at 0°
• Degree required counter-clockwise from 0.

Key flats are available as single flat, double flat or for dowels.
