Detailed description

Custom CNC Milled Aluminum Fixture Locating Stop Block

Our custom CNC Milled Aluminum Fixture Locating Stop Block is a stepped irregular precision jig component with positioning slope and mounting hole structure. As a professional multi-axis CNC machining manufacturer based in Dongguan, we produce customized aluminum locating stop blocks with ±0.01mm ultra-precise tolerance strictly following customers’ 2D & 3D engineering drawings. We support full OEM & ODM customization for overall contour, slope angle, hole distribution and step dimension. These aluminum fixture locating stop blocks are widely used for workpiece limiting, positioning and blocking in automation assembly fixtures, electronic test jigs and precision processing equipment.

Introduction to CNC Milling Technology

CNC milling is one of the most precise and efficient manufacturing methods for complex non-rotational metal components used in industrial automation and precision equipment. Using programmable 3/4/5-axis milling centers, solid metal blanks are shaped through continuous face milling, cavity machining, tapping, boring and contour cutting operations with computer-controlled accuracy.
Compared with manual machining and traditional turning, precision CNC milling delivers consistent dimensional tolerances down to ±0.01mm, smooth surface finishes and excellent repeatability across high-volume production runs. It is widely used to produce fixture blocks, mounting brackets, locating jigs, connecting plates and machined housings for mold tooling, electronic devices, medical equipment, automotive systems and industrial automation machinery.
With advanced multi-axis milling capabilities and secondary tapping support, CNC milling technology supports custom geometries including irregular profiles, multi-position hole arrays, stepped platforms and precision grooves, which perfectly meets the diversified demands of precision fixture components for industrial equipment.

What Is Aluminum Fixture Locating Stop Block & Its Industrial Role

An aluminum fixture locating stop block is an integrated precision limiting part equipped with positioning inclined surfaces, stepped profiles and installation holes. The special-shaped contour and stop surface realize accurate limiting of workpieces, while reserved mounting holes enable quick installation on jig bases. It effectively prevents workpiece offset and displacement during continuous assembly and testing procedures.
In automated assembly tooling, electronic testing fixtures and precision machining equipment, aluminum fixture locating stop blocks undertake critical limiting and positioning tasks. Reliable flatness, precise angle tolerance and stable hole position accuracy are essential to maintain long-term repeated positioning consistency. Therefore, custom CNC milled aluminum fixture locating stop blocks are indispensable core hardware for high-precision automation jig systems.

We provide one-stop custom CNC milling solutions for aluminum fixture locating stop blocks and various precision non-standard jig limiting components, serving automation equipment manufacturers, electronic testing factories and precision machinery enterprises worldwide.
Our production range covers all types of customized stop block hardware: inclined locating stop blocks, stepped fixture limiting blocks, workpiece positioning stoppers, jig backstop blocks and non-standard special-shaped positioning blocks.
All products are manufactured via integrated CNC milling, contour forming, drilling and deburring processes. All machining standards and surface treatments are strictly implemented in accordance with your engineering drawings. Apart from individual finished locating stop blocks, we also supply matched auxiliary locating parts to simplify your assembly and material management.

Key Advantages of Our CNC Milled Aluminum Fixture Locating Stop Blocks

Ultra-precise dimension & reliable positioning accuracy

All fixture locating stop blocks are processed on multi-axis CNC milling equipment with whole-process dimensional monitoring. Unified contour size, inclined surface angle and hole spacing ensure stable limiting precision for each batch, avoiding workpiece positioning deviation.

Flexible personalized structural customization service

Based on 5-axis CNC milling processing, we support free customization of overall outline, slope angle, hole layout, step height and stop surface shape. We adjust structural parameters according to your fixture installation space requirements to reduce your secondary processing workload.

Outstanding aluminum alloy mechanical performance

We adopt premium 6061/7075 aluminum alloy raw materials with light weight, sufficient rigidity and good oxidation resistance. Multiple surface treatment options can be selected to adapt to long-term continuous workshop working environments.
