Design of Multi-Angle Fixtures for CNC Wire EDM Machines

When manufacturing CNC wire EDM machines, clamping and processing some specific special workpieces will likely lead to challenges in meeting quality demands. In response to this issue, a highly practical and useful multi-angle fixture is designed for CNC wire EDM machines to handle these special workpieces. This fixture does not only improve the machining accuracy of special workpieces but it also meets their production volume requirements.

Benefits of Using Multi-Angle Fixtures in Wire EDM

1. Achieving Multi-Angle Cutting

Wire EDM machines operate under CNC control, where cutting at different angles is vital to meet the needs of non-regular shapes demanded by most engineering designs. The use of special fixtures that can facilitate multi-angle clamping positions and flexibility on the angles allows the wire to cut at various required angles easily; this helps in addressing precision-related concerns as well as achieving high efficiency during the process.

2. High-Precision Positioning

Wire EDM requires precise positioning and clamping to ensure the workpiece remains stationary during processing. Stabilization of the workpiece is made possible through the accurate clamping capabilities provided by multi-angle special fixtures. In addition, this also ensures proper positioning which in turn guarantees the accuracy and quality of cutting.

3. Simultaneous Processing of Multiple Workpieces

CNC wire EDM frequently engages in batch processing of several workpieces at a time. Conventional fixtures require frequent changes, impacting production efficiency. In contrast, a multi-angle special fixture can hold down multiple workpieces at once, reducing the time required for those changeovers and adjustments while also improving production efficiency.

4. Flexibility and Adaptability

Multi-angle special fixtures can be altered to fit different kinds of workpieces, no matter the shape or size, to meet many varied cutting demands for prototype development. The adjustable structure of the fixtures allows for flexible modifications based on processing requirements, providing better adaptability.

5. Safety and Stability

Through rational structural design and strong clamping force, multi-angle special fixtures ensure that workpieces do not move or detach during high-speed cutting, guaranteeing operational safety and stability, and reducing the risk of accidents.

For robust clamping ability, multi-angle special fixtures typically offer strong force and stability, securely holding the workpiece in place to prevent any loosening or sliding during cutting. This robust clamping eliminates tool collision possibilities or degradation in cutting quality due to workpiece displacement — ensuring safety issues are addressed.

Considerations for the Design of Multi-Angle Fixture Parts

The creation of components for multi-angle specialized fixture in CNC wire-cutting involves the structure design and choice of materials. Multi-angle specialized fixture is a fixture used to secure workpieces and process them at various angles in structural design. Its main structural components include clamping devices, support devices, and adjustment devices which have to be processed through detailed design and optimization during the prototype development phase.

  • Clamping Device: The clamping device is an essential element for workpiece holding, which comprises parts like jaws and chucks. Factors that should be taken into account in the design of the clamping jaws during prototype development include clamping force, balance and protection of contact areas with the workpiece; this guarantees stability and integrity of the workpiece during machining operations.
  • Support Device: An AI is a support device that provides steady support to the supported object. It should consist of bases and guide rails which contribute to stability in design while considering this aspect as well as rigidity when constructing a fixture would be beneficial for prototype development and reliability during machining at various angles.
  • Adjustment Device:Another important element in the support mechanism is an adjustment device that helps change the clamping angle. Adjustment screws and rods are integral components of this system, and they should be designed with precision in mind for accurate adjustments of angles.

In the materials selection for manufacturing a multi-angle specialized fixture, strength, and wear resistance should be considered, as well as the manufacturing costs and processing difficulty.

Commonly used materials include steel, aluminum alloy, and engineering plastics. Steel, such as common tool steel and alloy steel, provides high strength and rigidity, making it suitable for bearing significant forces and pressures. Aluminum alloy, with its excellent lightweight properties, is suitable for situations where weight is a critical factor and is also easy to process and assemble. Engineering plastics, like nylon and polyurethane, offer high mechanical performance and wear resistance while being lightweight and having good insulation properties.

Additionally, the production process and technology needs of the fixture should be considered for quality assurance and reliability of the design. The design should also focus on the proper fit precision between parts and different limitations of processes so that its functionality and performance can meet intended objectives.

Design Principles of Multi-Angle Specialized Fixtures

The essential principles that constitute the design of multi-angle specialized fixtures in CNC wire-cutting machines are:

Fixtures need to stay stable

Ensure the stability of the multi-angle specialized fixture. This aspect involves ensuring that when the fixture is being designed, there should also be an analysis of the workpiece stability during processing which consists of determining structural form and material properties including a clamping force amount and position to ensure rationality. The analysis of the workpiece structural characteristics in relation to how it will not deform after clamping can help establish a proper fixing: such as the structural form, clamping method and force, which can guarantee that the workpiece remains stable without any deformation during clamping.

Angle adjustment mechanism

The fixture needs to flexibly adjust the workpiece’s angle to meet different processing requirements. This can be achieved by using adjustable clamping surfaces or fixture components in the design. These parts can change the workpiece’s angle within a given range by the angle adjustment mechanism. Additionally, precise and stable angle-locking capabilities are needed for the angle adjustment mechanism to ensure the accuracy and stability of the clamping angle.

Consideration of cooling and chip removal

When CNC wire-cutting machines operate, a considerable amount of heat and metal chips are produced; this affects the stability and longevity of the fixture. Thus, in the machining process of multi-angle specialized fixtures, it is essential to consider cooling and chip removal. One way to lower the temperature of the fixture is by introducing cooling devices into its structure — for example, a coolant circulation system can be adopted. Additionally, designing of proper chip removal slots or channels so that metal chips can find easy passage out.

Ergonomics consideration

To the heart of ergonomics. When designing multi-angle specialized fixtures, the ease and effectiveness for the operator must be taken into full consideration. The fixture should be designed in a way that makes clamping, adjustment, and disassembly easy tasks without compromising on the operator’s effort or difficulty in operation. By making a thoughtful layout of fixture components and incorporating auxiliary adjustment devices, both operational performance and adherence to ergonomic standards can be enhanced with regard to the multi-angle specialized fixture.


More and more mold manufacturing companies choose multi-angle specialized fixtures for machining parts during the processing of CNC wire-cutting machines. with these fixtures, the clamping depth of mold parts can be significantly increased, meeting the machining requirements for mold parts at different angles. These technological advancements consequently lead to cost reduction for enterprises; it also shorten the development cycle of molds which later meets high-precision manufacturing demand for products.
