The Basic Type Thick Turret Tooling is a no-frills yet efficient solution for metalworking with thick materials. It is a staple in many metal fabrication shops due to its simplicity and reliability. The tooling is made from quality materials that are capable of withstanding the forces generated during the punching and shaping of thick metal sheets. Its design is focused on providing a practical and straightforward solution for basic metalworking tasks. The Basic Type Thick Turret Tooling is compatible with a broad range of turret punch presses, making it a versatile option for different manufacturing environments. It is a tool that gets the job done without the complexity of more advanced tooling systems.
1. Assembly ArchitectureThe Original Type B assembly consists of three primary components that are manually assembled:
*The Punch Body: A solid, integral piece of tool steel (usually M2 HSS) with a precision-ground shank and a hexagon or "D" shaped head.
*The Guide: A non-hardened or semi-hardened housing that holds the punch. In "Original" style, the guide typically features a single keyway for fixed orientation.
*The Spring Pack: A set of heavy-duty coil springs held together by a metal retainer and a bolt.
2. Manual Length Adjustment (Shimming)
*The most defining characteristic of the Original Type is how it handles tool sharpening:
*Non-Click Adjustment: There are no adjustment rings. When the punch tip is reground to restore the cutting edge, the overall length of the tool decreases.
*Use of Shims: To maintain the correct "shut height" (the distance the punch travels into the die), the operator must place precision metal shims between the punch head and the spring driver.
*Reversible Retainers: Some versions feature a "reversible spring retainer" that can be flipped to provide a fixed amount of length compensation (typically 2.0mm) before shims are required.
3.Feathure
Max Diameter: 1.250" (31.75mm).
Adjustment Increment:Manual (dependent on shim thickness, usually 0.5mm to 1.0mm).
Punch Material:Standard M2 High-Speed Steel.
Lubrication:External only; generally lacks the internal "Air-Blow" ports found in NEX/Ultra styles.
Stripper Type:Flat, non-guided stripper plates held by manual spring tension.
4. Operational Characteristics
*Fixed Orientation: Original type guides usually have a single key at the 0° position. If you need to punch at 90°, you must physically remove the tool, rotate the punch inside the guide (if the design allows), or use a differently keyed guide.
*Simplified Maintenance: Because there are no complex "click" mechanisms or ball-bearing adjustment heads, the tools are extremely rugged and less prone to jamming from fine metal dust or "slug mist."
*Cost-Effectiveness: These tools have a lower initial purchase price, making them the "Economy" choice for shops that do not require frequent tool height changes.

Die clearance
The chart is also based on experiences from customers who achieve superior piece partquality and the longest possible tool life.
Blanking tools are generally assigned with less clearance than piercing tools so that the burnishedarea of the piece part (slug) is greater. This leads to a higher quality piece part. Due to the smallerclearances, blanking tools may become dull more quickly.
TIN,TICN,DLC coating
1. TiN (Titanium Nitride)
Often referred to as the "Gold Coating," TiN is the industry standard for general-purpose punching.
Color: Bright Metallic Gold.
Hardness: ~2300 HV (Vickers).
Primary Benefit: Provides a significant increase in surface hardness and serves as a thermal barrier.
Best For: Mild steel, carbon steel, and some plastics.
When to Use: It is the best "bang for your buck" upgrade. It typically extends tool life by 3 to 5 times compared to uncoated tools by reducing abrasive wear.
Limitation: It is not recommended for stainless steel or copper/nickel alloys because the titanium can chemically react with those metals, leading to "galling" (material pickup).
2. TiCN (Titanium Carbonitride)
TiCN is an evolution of TiN, where carbon is added to the chemical structure to make it harder and "slicker."
Color: Blue-Grey or Bronze-Grey.
Hardness: ~3000 HV (Harder than Carbide).
Primary Benefit: High abrasion resistance and improved lubricity. It is "tougher" than TiN and can handle higher impact forces.
Best For: Stainless Steel, galvanized steel, and high-strength alloys.
When to Use: If you are punching stainless steel or high-tensile materials, TiCN is the standard choice. It prevents the sheet material from "welding" itself to the side of the punch tip.
Limitation: It has a lower temperature threshold (~400°C) compared to TiN (~600°C), meaning it requires good lubrication if running at extremely high hit rates to avoid oxidizing.
3. DLC (Diamond-Like Carbon)
DLC is a high-tech amorphous carbon coating that mimics the properties of a natural diamond. In punching, it is often considered the "ultimate" anti-galling solution.
Color: Shiny, Mirror-like Black.
Hardness: Up to 5000–9000 HV (depending on the specific formula).
Primary Benefit: Extremely low coefficient of friction (often below 0.1). It is essentially a "self-lubricating" hard shell.
Best For: Aluminum, copper, brass, and other non-ferrous "sticky" metals.
When to Use: Specifically used to prevent galling. Aluminum is notorious for sticking to punch tips; DLC’s slick surface allows the punch to slide out of the hole without pulling material with it.
Limitation: It is brittle and has low heat resistance (degrades above 350°C). It is generally not used for heavy-duty steel punching where heat and high-impact "shock" are the primary wear factors.
Air Blow system Tooling
Air blow systems in punch tooling offer significant advantages in terms of efficiency, precision, and tool life. They are versatile and suitable for a wide range of industrial applications, from automotive to electronics. Proper installation and regular maintenance ensure that these tools continue to perform at their best, contributing to high-quality production processes.
The system supplies an air/oil mixture to lubricate critical components of the tooling, including the punch body, guide channels,
and punch tip.This internal and external lubrication reduces friction, prevents galling, and extends the life of the punch and die
