Pulling (Broaching) at Batchforce

Traits: High-Quality Profiling for Sector-Specific Applications

Drawing, also known as broaching, is a highly efficient technique for creating detailed internal and external profiles in parts. This method is essential for industries such as pipeline inspection and medical device manufacturing, where precision and reliability are crucial. Drawing makes it possible to accurately create complex shapes in a single operation, which both saves time and ensures a high degree of precision. For purchasing managers, this technique offers significant advantages, such as eliminating expensive secondary machining and ensuring strict compliance with specifications.

Benefits of Pulling

• High Precision: Drawing makes it possible to produce complex internal and external shapes with a high degree of accuracy, allowing parts to meet tight tolerances.
• Efficiency in Production: The process of pulling allows detailed profiles to be created in one operation, saving time and cost over other machining methods.
• Material diversity: Suitable for machining hard and tough materials, such as hardened steels and titanium alloys, which is critical for applications in demanding industries.

Disadvantages of Pulling

• Limitations in Complexity: Although pulling is highly accurate, extremely complex designs may require multiple steps or special broaches, which can increase production time and cost.
• Cost of Tools: Manufacturing specialized broots can be expensive, especially for small production runs.
• Material limitations: Although pulling is suitable for many metals, it can be less effective with very soft or nonmetallic materials, limiting its applicability.

Pulling Capacities

1. Internal Drawing
   Internal drawing offers precision to ±0.02 mm, making it ideal for creating keyways and splines in components up to 500 mm long. This technique is essential for manufacturing parts that must meet very stringent specifications.
2. External Drawing
   External drawing is suitable for making complex profiles on parts up to 200 mm in diameter. This technique is often used in industries where accuracy and durability are critical, such as the aerospace and automotive industries.

Maximum Length and Diameter

• Maximum Length: Up to 800 mm, which is sufficient for most industrial applications.
• Maximum Diameter: Up to 250 mm, providing the capacity to machine larger parts.

Typical Materials

We have expertise in machining hardened steels, titanium alloys and other demanding materials. This makes drawing an ideal technique for applications where material strength and wear resistance are essential, such as aerospace and precision parts in the medical industry.
