Reasons to Use Custom Fixtures

CNC (Computer Numerical Control) machines are critical to the manufacturing industry. They are used in various fields, from aerospace and defense to medical and automotive industries. CNC machines are versatile, reliable, and precise. However, to get the most out of a CNC machine, it is essential to have the fixture & tooling setup. A custom fixture is a specially designed and fabricated tooling setup that is tailored to a specific application. In this paper, we will discuss the benefits and reasons for using custom fixtures in CNC machine shops.

Increased Efficiency:

One of the primary reasons to use a custom fixture is to increase efficiency. A custom fixture is designed to fit a specific workpiece and machining operation. This means that the fixture will securely hold the workpiece and allow for precise machining without chatter or vibration. As a result, the machining process will be faster and more accurate, increasing efficiency and productivity.

Improved Quality:

A custom fixture is designed to fit the workpiece perfectly, which ensures that the machining process is as accurate as possible. This results in a higher-quality finished product. A custom fixture also allows for better chip evacuation and coolant flow, which reduces the risk of chip buildup and overheating. Additionally, a custom fixture can reduce the risk of tool breakage, which can cause damage to the workpiece and result in scrapped parts.


Fixtures are designed to be flexible. They can be modified or adjusted to fit different workpieces or machining operations. This means that a custom fixture can be used for multiple applications, which makes it a cost-effective solution for CNC machine shops. Instead of purchasing a new fixture for each job, a custom fixture can be adapted to fit various workpieces, which reduces costs and increases productivity.

Cost Savings:

A custom fixture may have a higher initial cost compared to a standard fixture, but it can result in significant cost savings in the long run. A custom fixture is designed to last longer than a standard fixture. It can be easily repaired or modified if needed. A custom fixture also reduces the risk of scrapped parts, which can save money on material costs and labor and can prevent long unplanned lead times for your customers.


Custom fixtures offer several benefits for CNC machine shops. They increase efficiency, improve quality and consistency, provide flexibility, and result in cost savings. A custom fixture is designed to fit a specific workpiece and machining operation, which ensures a faster, more accurate machining process. It also reduces the risk of tool breakage and scrapped parts, which saves money on material costs and labor. Overall, a custom fixture is a smart investment for CNC machine shops looking to improve their productivity and profitability and can be a necessity for them to provide you the best possible parts at the most cost-effective price points.
