★★★★★
In my 15 years of as a QA manager I have never worked with an instrument which is so incredibly simple to operate. When we first got the equipment it took just a few minutes for me to figure it out. Moreover, by the second hour I was comfortably teaching my newer staff how to operate the machine. I love the library of common tensile dimensions and the ability to enter custom data on the touch screen controller. It is rear to see a dummy proof equipment on the market. We than TensileMIll CNC. Inc. for figuring this one out. Armando F. QA Manager – MST Steel The Software is astonishing! We particularly enjoy the library of common standards.
QA Manager – MST SteelThe Software is astonishing! We particularly enjoy the library of common standards. In our initial discussion of technical specifications, we asked for the machine to be programmed for the ASTM E8 standard based on our customer needs at that time. We were pleasantly surprised to find the software was equipped with many ASTM, ISO, JIS, and DIN standards. This came particularly handy when our recently acquired customers needed us to prepare them with tensile samples according to ISO standards. Shannon R. Quality Control Engineer – Denso Manufacturing and Denso Automotive Group Happy with our investment. We received a better value at a more competitive price.
Quality Supervisor – Extruded Aluminum CorporationHappy with our investment. We received a better value at a more competitive price. Before buying, we sourced 3 quotations, including TensileMill. TensileMill met all technical needs and had the added value of the easy to use software interface. The unit was lower priced relative to the competition and fit well in our budget. Justin P. Quality Supervisor – Extruded Aluminum Corporation We specialize in part production with inconel metals. Our meterials are upwards of 50HRC and require a tensile tester with 5000 kN capacity. Daily we prepare roughly 30-40 samples. We were out there looking for a robust and user-friendly machine to be operated by our junior engineers in our new R&D division.
I give a 5-star review for TensileMill CNC for their exceptional quality, user-friendliness, and technical support for the purchase of a 100kN Universal Testing Machine. Firstly, the quality of the machine is exceptional. It is evident that TensileMill CNC takes great pride in their work and pays attention to every detail of the manufacturing process. The machine is built to last, and its precision and accuracy are remarkable. Secondly, the user-friendliness of the machine is second to none. The software is intuitive and easy to use, and the machine is straightforward to set up and operate.

Quality Control Manager – Valmont IndustriesFrequently Asked Questions
Quick answers to the questions we hear most often about tensile sample preparation. Browse the full knowledge base for detailed guidance on machines, standards and workflows.
What does TensileMill CNC do?
TensileMill CNC designs and builds automated equipment for tensile specimen preparation and materials testing. The range covers flat and round CNC sample preparation machines, universal testing machines, longitudinal polishing, grips and fixtures, and the consumables that keep them running.
The goal is to bring accurate, standard-compliant testing fully in-house. Explore our full product range.
What products does TensileMill CNC offer?
The lineup covers the whole tensile testing workflow:
- Flat and round CNC specimen preparation machines
- Electromechanical and servo-hydraulic universal testing machines
- Longitudinal polishing systems
- Grips, fixtures, and consumables
Sourcing the full chain from one supplier keeps it consistent. Explore our full product range.
Why prepare tensile specimens in-house?
Preparing specimens in-house removes the cost and delay of outsourcing, which can run $150 to $300 per sample, and puts your test schedule under your own control. Automated CNC preparation also gives you repeatable, standard-compliant geometry that manual methods struggle to match.
In-house control means faster, more consistent testing. Explore in-house flat specimen preparation.
Which standards does TensileMill CNC equipment meet?
The equipment is built around the widely used tensile and testing standards, including:
- ASTM E8 / E8M and ISO 6892-1 for tensile testing
- DIN 50125 and JIS Z 2241 for specimen geometry
- ASTM E4 and ISO 7500-1 for machine force verification
The right machine or fixture is matched to your standard. See our standards and certification.
Which industries does TensileMill CNC serve?
Our equipment is used across sectors that depend on verified material properties, including aerospace, automotive, metals production, manufacturing, universities, and independent test labs. Each relies on accurate, traceable tensile data.
Whatever your field, the equipment is matched to your standards and materials. To discuss your application, talk to a specialist.
Do you provide installation, training, and support?
Yes. Installation and operator training are available for all systems, backed by a global support network with remote guidance and on-site service. The aim is to keep your equipment running at peak accuracy with minimal downtime.
Support is built into ownership, not an afterthought. Explore our support options.
Do you offer certification and calibration?
Yes. Working with ISO 17025 accredited laboratories, we certify and calibrate testing machines, load cells, extensometers, and specimen preparation equipment to ASTM and ISO frameworks. This keeps your results traceable and audit-ready.
Certified equipment is what makes your data defensible. See our standards and certification.
