Key Takeaways
Jigs and fixtures are essential in modern manufacturing, enabling the achievement of precision, consistency, and efficiency across production processes. Jigs guide machining tools along predefined paths, while fixtures hold workpieces securely in place to maintain accuracy during operations.
Different types of jigs and fixtures serve specific purposes. Template and plate jigs guide cutting or drilling tools for repeatable accuracy, channel jigs support linear operations, and indexing fixtures enable controlled rotation or repositioning of parts. These tools are widely used across the aerospace, automotive, and electronics industries to ensure tight tolerances and reliable output.
Advancements in technology have also improved traditional jig and fixture systems. Modern designs now integrate automation, precision sensors, and quick-change mechanisms, allowing manufacturers to achieve faster setups, greater flexibility, and superior quality control.
What are Jigs and Fixtures?
Jigs and fixtures are essential custom-made tools widely used in precision machining and manufacturing industries. They play distinct yet complementary roles in ensuring accuracy, repeatability, and efficiency during production.
A jig is a guiding tool that holds the workpiece and directs the cutting or machining tool to the exact location. This precision guidance ensures that every hole, slot, or cut is consistent and accurate. Meanwhile, a fixture primarily holds and secures the workpiece firmly in place without guiding the tool, stabilising it during various machining operations to maintain correct positioning.
Together, jigs and fixtures enhance the manufacturing process by reducing human error, increasing productivity, and improving product quality. Their design requires careful consideration of the specific machining needs and the characteristics of the workpieces involved, including material, shape, and size.
Key Components of Jigs and Fixtures
The success of jigs and fixtures in achieving precision and stability during machining depends on three primary components:
Body
Acts as the core structure that provides stability and support for the workpiece.
Designed based on the complexity of the machining task and the shape of the workpiece.
Commonly made from durable materials such as cast iron or welded mild steel.
May undergo heat treatment to relieve internal stresses and enhance strength.
Precision-cast sections are often used, especially in fixtures, to ensure rigidity and stability.
Locating Devices
Ensure the precise positioning of the workpiece relative to the cutting tool.
Typically made from hardened steel for durability.
Include locating pins that accurately lock the workpiece in place.
Use support locating pins or dowel pins to stabilise flat surfaces and maintain correct orientation during machining.
Clamping Devices
Secure the workpiece firmly to prevent movement or vibration during machining.
Must apply sufficient clamping force to hold the workpiece without causing deformation.
The clamping method depends on the part’s geometry, machining forces involved, and the specific application.
Proper selection and application of clamping are vital to maintain precision and part integrity.
NVT Technology carefully designs and applies these components when engineering jigs and fixtures for internal CNC operations, ensuring aerospace and defence parts are held securely and positioned accurately throughout every stage of production.

Frequently Asked Questions
What is the primary difference between a jig and a fixture?
The primary difference between a jig and a fixture lies in their function during machining operations. A jig is designed to guide the cutting tool—such as a drill or saw—precisely to the correct location on the workpiece, ensuring accuracy and repeatability in tool positioning. It essentially directs the tool’s movement relative to the part. In contrast, a fixture’s primary role is to firmly hold and accurately locate the workpiece itself, providing stability and preventing movement during machining. While a jig actively guides the tool, a fixture passively secures the part, and both work together to achieve precision in manufacturing.
How do modular fixtures benefit manufacturing processes?
Modular fixtures offer tremendous advantages in manufacturing by providing adaptability and ease of use across a variety of part geometries and production runs. Their interchangeable components and standardised parts allow manufacturers to quickly reconfigure setups to accommodate different designs without the need for custom fixtures each time. This flexibility drastically reduces machine downtime and setup time between jobs, increasing overall productivity. Additionally, modular fixtures can be scaled or combined for more complex assemblies, supporting efficient batch production and reducing tooling costs. Their versatility makes them ideal for dynamic manufacturing environments where rapid changeovers are frequent.
How do plate jigs enhance the functionality of template jigs?
Plate jigs build upon the basic concept of template jigs by integrating drill bushes, which are hardened metal inserts that guide the drill bit with exceptional precision. This addition dramatically improves drilling accuracy, especially for large or complex components where slight deviations can lead to significant quality issues. The drill bushes reduce wear on the jig and extend its lifespan while ensuring consistent hole placement across multiple parts. As a result, plate jigs provide greater reliability and repeatability in manufacturing, helping to maintain tight tolerances and improve overall product quality.
Why are broaching fixtures important in the automotive and aerospace industries?
Broaching fixtures play a vital role in the automotive and aerospace sectors by ensuring that workpieces are perfectly aligned and securely supported during the broaching process. This machining operation removes material using a toothed tool. Because these industries demand extremely high precision and consistency for safety and performance reasons, broaching fixtures help achieve exact material removal and tight dimensional control. They minimise vibrations and movement, leading to superior surface finishes and extending tool life. By improving accuracy and efficiency, broaching fixtures contribute directly to producing reliable, high-quality components essential for critical applications.
What are the advantages of vacuum-based clamping systems?
Vacuum-based clamping systems present significant advantages, particularly when handling delicate or thin workpieces that traditional mechanical clamps might damage. By using the suction force generated by vacuum pumps, these systems secure the workpiece evenly across a large surface area without applying localised pressure or causing deformation. This method ensures that fragile materials like glass, composites, or polished metals remain intact and undistorted during precision machining or inspection. Additionally, vacuum clamping allows for quicker setup and release, enhancing workflow efficiency. Its non-intrusive nature makes it highly suitable for industries requiring meticulous handling and high-precision results.
