High-Quality dividing head

A high-quality dividing head, also known as an indexing head, is a precision tool essential for machining equally spaced features on workpieces. It allows for precise rotation and positioning, enabling operations like gear cutting, fluting, and drilling bolt circles. This guide explores the types, features, and applications of high-quality dividing heads, helping you choose the right one for your needs.

Understanding Dividing Heads

What is a Dividing Head?

A dividing head is a machine tool accessory used to accurately divide a circle into equal segments. It holds a workpiece securely and allows it to be rotated to precise angles. This is crucial for creating parts with evenly spaced features.

Types of Dividing Heads

Several types of dividing heads exist, each suited for different applications. The most common types include:

• Direct Indexing Head: The simplest type, with a plate having a specific number of holes. The spindle is locked into these holes for direct division.
• Simple Indexing Head: Uses a crank and indexing plate with multiple hole circles for various divisions. Offers more flexibility than direct indexing.
• Universal Indexing Head: The most versatile type, capable of simple indexing, differential indexing, and spiral cutting. Often used with a gearbox and change gears.
• Semi-Universal Indexing Head: A simpler version of the universal type, typically lacking the spiral cutting capability.

Key Features of a High-Quality Dividing Head

When selecting a high-quality dividing head, consider these features:

• Accuracy and Precision: Look for a head with minimal backlash and high indexing accuracy. Quality bearings and construction are essential.
• Rigidity: A rigid body prevents vibration and ensures accurate machining. Cast iron or steel construction is preferred.
• Spindle Bore Size: The size of the spindle bore determines the maximum workpiece diameter that can be accommodated.
• Indexing Plate Options: A variety of indexing plates allows for a wider range of divisions.
• Tailstock Compatibility: A tailstock provides additional support for long workpieces, improving stability.
• Ease of Use: Clear markings and smooth operation enhance usability.

Applications of Dividing Heads

Dividing heads are used in various machining operations, including:

• Gear Cutting: Creating gears with accurately spaced teeth.
• Fluting: Cutting flutes in taps, reamers, and end mills.
• Drilling Bolt Circles: Drilling equally spaced holes on a circular pattern.
• Milling Keyways: Cutting keyways in shafts.
• Spline Cutting: Creating splines on shafts.

Choosing the Right Dividing Head

Selecting the appropriate dividing head depends on your specific needs and applications. Consider the following factors:

• Type of Machining: Determine the types of operations you will be performing (e.g., gear cutting, fluting, drilling).
• Required Accuracy: Assess the required precision for your projects.
• Workpiece Size: Consider the size and weight of the workpieces you will be machining.
• Budget: High-quality dividing heads can range in price. Set a budget and look for the best value within that range.
