Dillon Manufacturing Introduces Soft Jaws with Easy Location Features for Faster CNC Setup!

Dillon Manufacturing has expanded its workholding solutions portfolio with the introduction of new soft jaws featuring integrated easy location features designed to reduce setup time and improve machining accuracy. Developed for both CNC and manual chuck applications, the new soft jaws help machinists achieve faster, more consistent setups while enhancing workholding precision for turning and boring operations. By incorporating built-in reference surfaces into the jaw design, Dillon aims to simplify machining preparation, improve repeatability and increase productivity across a wide range of manufacturing environments.

One of the key innovations of the new soft jaws is the precision-milled locating surface incorporated into the jaw end of each soft jaw blank. This machined reference surface provides operators with a clearly defined locating feature that enables rapid positioning during subsequent machining operations. Instead of manually establishing new reference points for every setup, machinists can use the integrated datum to align workholding components more quickly and accurately, reducing preparation time and improving workflow efficiency.

The locating feature is positioned opposite the primary clamping surface, allowing it to function as a stable reference point during jaw machining and customization. This datum simplifies the positioning of critical machining features such as counter-bored mounting holes and jaw serrations, helping ensure that each jaw is machined consistently. By providing an accurate reference throughout the manufacturing process, the design minimizes setup variation and enables greater dimensional consistency between multiple jaw sets.

The improved accuracy offered by the integrated locating features contributes directly to better workholding performance. Consistent jaw positioning enhances concentricity during clamping, ensuring that workpieces are held securely and accurately throughout machining operations. Improved concentric performance is particularly important in precision turning and boring applications where even small alignment errors can affect dimensional accuracy, surface finish and overall component quality.

In addition to improving workpiece positioning, the enhanced jaw design also contributes to better chuck balance during machine operation. More accurate machining and alignment of the soft jaws reduce imbalance within the chuck assembly, helping minimize vibration at higher spindle speeds. Improved balance not only enhances machining stability and surface finish quality but also reduces stress on machine tool components, contributing to longer equipment life and improved overall machining performance.

The precision locating features also play an important role in extending the service life of the soft jaws themselves. Greater machining accuracy during jaw preparation results in more even clamping forces and improved contact with the workpiece, reducing uneven wear over time. As a result, manufacturers can achieve longer jaw life while maintaining consistent workholding performance across extended production runs, lowering replacement costs and reducing maintenance requirements.

By aligning the established reference surfaces with the jaw serrations, Dillon Manufacturing has created a workholding solution capable of delivering reliable and repeatable performance across a broad range of machining applications. The soft jaws are well suited for both turned and bored components, enabling manufacturers to maintain high levels of precision while simplifying setup procedures for different part geometries and production requirements.

The introduction of these soft jaws reflects the increasing emphasis on reducing non-productive setup time within modern machining environments. As manufacturers continue to focus on improving machine utilization, minimizing downtime and increasing production efficiency, workholding systems that simplify setup while enhancing accuracy have become increasingly valuable. Dillon Manufacturing’s latest design provides machinists with a practical solution that combines ease of use with precision engineering, supporting both high-volume production and high-mix manufacturing operations.

With the addition of easy location features, Dillon Manufacturing’s new soft jaws offer manufacturers an efficient way to accelerate setup, improve workholding accuracy and enhance overall machining consistency. By reducing setup complexity and providing reliable reference points for jaw preparation, the solution helps shops achieve higher productivity, better machining performance and greater operational efficiency across a wide range of CNC and manual turning applications.
