Dedicated machines like the Blacks CNM integrate custom fixtures specifically for Charpy specimen preparation. While they excel in this single function, their limited versatility means customers often need additional specialized machines for other specimen types. This increases long-term costs. Additionally, sub-size fixtures for the Blacks CNM are optional add-ons, meaning customers must purchase extra fixtures for different specimen sizes.
In contrast, Qualitest's universal Mini CNC Milling Machines (such as the QualiMill M4 Desktop Mill and QualiMill-220 Desktop Mill) offer greater flexibility. These machines can process Charpy impact test specimens along with other workpieces, thanks to programmable adjustments and fixture swaps. This adaptability significantly enhances cost efficiency and operational flexibility.
Adaptation Strategy: Smooth Integration with Existing and New Fixturing
A. Supporting Existing Fixtures
Facilities that have already invested in fixture designs for the Blacks CNM system don’t have to start from scratch. Qualitest offers technical support to evaluate existing fixtures and determine their compatibility with the Mini CNC platforms.
In many cases, minor modifications or adapter components can enable seamless integration, allowing labs to transition to a more flexible machining solution without losing the value of their current tooling investments. This approach minimizes downtime, reduces the learning curve for operators, and supports a cost-effective equipment upgrade.
B. Optimized for New Fixture Solutions
Qualitest Mini CNC machines are engineered with versatility in mind and can be equipped with a wide range of fixture options to accommodate multiple specimen types. Whether preparing Charpy impact test specimens, tensile bars, dog-bone profiles, or custom research samples, these systems are highly adaptable.
Custom fixturing can be developed based on the dimensional and geometrical requirements of your test standards or unique application needs. The CNC platform’s programmable controls ensure repeatable, high-precision cuts, while modular fixture designs allow for easy swapping and expansion as testing requirements evolve.
This flexibility in fixturing makes Qualitest Mini CNC systems a practical long-term solution for labs looking to expand capabilities, streamline operations, and reduce the number of specialized machines required on the shop floor.
So, here’s the summary:
- For Existing Fixture Compatibility: If customers already have fixture designs from Blacks CNM, Qualitest can verify their compatibility with our Mini CNC machines.
- For New Fixtures: Qualitest's Mini CNC machines are designed to accommodate various fixtures, making them ideal for Charpy impact specimens, tensile test specimens, and other sample types.
