Types of Universal Dividing Heads

An universal dividing head is an accessory that uses dividing and angular motion to cut gears and make various other types of machine parts. Here are some types:

• Standard Dividing Head: The standard dividing head, also known as the single or simple dividing head, offers a basic set of features for dividing workpieces into equal parts or angles. It typically has a set of interchangeable plates with common division for gears as well as other workpieces. Simple dividing heads allow operators to set the head at certain indices, rotate the workpiece, lock the head, and then machine the workpiece. Although these heads do not have automatic indexing systems, their straightforwardness and reliability make dividing heads suitable for many situations.
• Positive Stop Dividing Head: A positive stop dividing head offers stopping points within its framework. These stopping points are often marked in decimal or specific divisions on the index plates. With the help of these markings, operators can cut a workpiece into evenly spaced divisions. This makes positive stop dividing heads suitable for more complex work than standard ones. The plates have angles already set up so that operators don't have to do any calculations beforehand. They just need to divide the workpiece on the head of the dividing machine. Also, positive stop dividing heads usually have faster index rotations, which makes them a good choice for jobs that require high accuracy and a lot of work in a given time.
• Vernal Dividing Head: Vernal heads have fixed components but movable plates, which means variables can be changed. Movements and settings can be easily changed for accuracy with different sizes of divisions. Most heads allow flexibility to make work precisely fit what is needed, as changeable index plates give choices besides ordinary ones.
• Universal Dividing Head: This is the most advanced and flexible dividing head model. It features a built-in worm wheel and an indexing system that permits uniform workpiece division at various angles. Some models additionally have interchangeable plates with commonly used division patterns. Due to their high level of adaptability and effectiveness, universal dividing heads are appropriate for complicated machining operations that demand precise workpiece division and angular cutting.

Specifications and maintenance of universal dividing heads

The universal dividing head's specifications usually depend on the model of the dividing head in question. However, typical universal dividing heads' specifications include the following:

• Body material: The body material of a universal dividing head can be cast iron or aluminum alloy. Cast iron is a heavier metal that provides maximum rigidity and stability while working on materials. On the other hand, aluminum alloy is lighter in weight, making it easier to handle. This material may provide less stability than cast iron. However, it is a durable and corrosion-resistant material.
• Standard spindle size: Common spindle sizes are 3/4, 1, 1- 1/4, and 1- 1/2 inches. A spindle with a one-inch size is typical for most dividing heads. The spindle size of a dividing head influences the amount of work it can hold.
• worm gear ration: A universal dividing head has a worm gear ratio that determines how far the spindle rotates when the worm wheel is turned one full turn. Common worm gear ratios for dividing heads are 40:1, 60:1, and 80:1. A high worm gear ratio means the dividing head can be set to divide small angles. This is ideal for machining parts with intricate details.
• Angular accuracy: Universal dividing heads have angular accuracy of up to 30 seconds. This high precision makes them ideal for machining parts that require high accuracy, for example, aerospace components.

Proper maintenance of the dividing head is necessary to ensure its durability and optimum performance during operation. Universal dividing heads can be maintained by regularly lubricating their gears as well as the rotational spindle. Lubricating these parts reduces friction and prevents wear and tear. It also makes operation smoother.

Regular cleaning of the dividing head is another maintenance practice. It prevents dust and debris buildup that may affect the accuracy and precision of the machine when working on materials. At times, excess dirt and debris can cause damage to the device. Cleaning can be done using an air compressor or a soft brush.

Applications of the universal dividing head

The universal dividing head allows precise cutting of workpieces into equal divisions. It also allows the production of complex geometries, such as threaded holes and spiral grooves, without having to use manual techniques. One of the major advantages of the universal dividing head is that it reduces the use of tools and helps to increase efficiency, production, and accuracy.

Here are some of the applications of a universal dividing head in an industry:

• Divided Controlled Angular Cuts: The universal dividing head allows for the precise machining of workpieces that have angular features. It can be set to different rotational divisions, which makes it very useful for machining tapered shafts, making gears, or creating contoured profiles. No matter the complexity, the dividing head helps improve the machining accuracy and streamline the process.
• Thread Cutting: The universal dividing head can be used for internal and external thread cutting. It can be clamped with various tapers and used together with taps. This allows for accurate cutting of threaded workpieces. Using the dividing head eliminates the need for complicated jigs and fixtures, thereby simplifying the machining process.
• Spiral machining: H-spiral grooves on cylinders or shoulders can be accurately machined using a universal dividing head. H-spiral grooves are common on machine cylinders of lathes, milling machines, and other equipment. The grooves are often used to allow better distribution of heat and to give a better grip. Some also use spiral grooves for decorative purposes. The dividing head makes it very easy to accurately machine these spiral grooves.
• Helical Cutting: An helical feature is a workpiece with a screw-like shape. It includes objects like screws, bolts, and drill bits. Normally, helical features are complex, and the machining of them usually requires high accuracy. The universal dividing head allows easy and precise machining of helical features. Helical grooves can be cut on the dividing head with milling cutters.
• Repetitive Arrayed Machining: Arrayed workpieces are workpieces with a repeated array pattern. This includes things like gear teeth, keyways, and splines. The universal dividing head allows for easy machining of the arrayed workpieces with a high level of accuracy. It also allows for easy setup and repetitive machining.

How to choose a universal dividing head

When looking for dividing heads for sale, it helps to understand how they are made and what features affect performance. With this information, one has a better chance of finding those popular selling models.

A universal dividing head is built with precision-engineered parts like cast iron housings, worm gears, and shafts. The cast iron housing protects internal parts from damage and helps keep them stable when working under different temperature conditions. This enables the jobber to achieve precise cuts. What divides the head into sections is the worm gear, which determines how much the workpiece will turn per cycle. Worm gears are usually made from low-carbon steel to help them withstand years of use without wearing out. Steel has a higher durability than cast iron does. Its importance is linked directly to dividing a workpiece into sections. If the worm gear wears out, it will throw off the alignment, rendering the dividing head useless.

Other parts worth mentioning are the tailstocks, spindles, and work table. Their functions are straightforward, so operators and machinists get them quickly. Workpieces are mounted on the spindle of a dividing head. The tailstock then secures it to remain in position while the table supports it. These parts can be easily recognized by their shiny metallic surfaces and ergonomic designs so that users can work unhindered.

Consider choosing dividing heads with additional accessories. These include tailstock centers and clamping kits. Tailstock centers support long parts while clamping kits stabilize the workpiece further to achieve precision.
