Flat Tensile Sample Preparation Machine


With TensileMill CNC - Flat Specimen Preparation it has never been easier to prepare high quality tensile specimens with ease. Our TensileMill CNC is operated by our powerful Carbon software with a user friendly tensile milling interface. The interface allows the operator to quickly and easily enter your desired tensile specimen size based on the parameters listed in your ASTM, ISO, DIN, JIS or other industry standard. By simply entering your required measurements, the machine is ready to mill in seconds.

The tensile software interface saves and provides quick access to previously entered specimen sizes. It also includes a diverse library of preprogrammed tensile specimens allowing the operator to quickly launch a program without having to enter any measurements at all. With your new TensileMill CNC - Flat Specimen Preparation, you also have access to our standard Carbon software interface; our intuitive and powerful CNC control system with endless possibilities.


Our easy to use touch screen controller is equipped with our complete Carbon software. Our control systems include 64 Gb of storage, 4 Gb of RAM, WiFi, Ethernet, USB ports, macro B programming, 254 tool offsets, 126 work offsets, helical interpolation, drilling canned cycles, scaling and mirroring, advanced trajectory planning, cutting edge dual mode cutter compensation, and more. Along with the tensile milling software interface, Carbon also allows the operator to access the MACH4 Industrial CNC Software used for professional CNC Control functions. Our Carbon software is constantly having new features developed, and every TensileMill CNC system includes updates at no additional cost.

Is TensileMill CNC classic considered a small CNC mill?

The Classic model, though robust and powerful when it comes to tensile sample preparation is considered a small CNC mill. With relatively compact dimensions of 49.2 x 57.1 x 76.8 in (1250 x 1450 x 1950 mm) the Classic is capable of fitting within virtually any "smaller" laboratory facility.

When choosing the right tensile specimen preparation machine, we suggest that you request a detailed quotation for the optimal machine.

What software comes standards with the TensileMill CNC Classic? TensileSoft™ – Flat Tensile Sample Preparation Software

TensileSoft™ is the standard CNC software that comes with the purchase of the TensileMill CNC Classic unit. This advanced software allows an operator to benefit from a variety of functions that make tensile sample preparation a walk in the park.

Firstly, the software comes with common industry standards that are widely used in the tensile samples preparation industry. ASTM, ISO, JIS and DIN are some of the examples. This means the operator can select ASTM → ASTM E8 and Press Go to begin the milling process. It is that simple.

What is more exciting is the FAVOURITES section found on the software which allows to access the most commonly used milling parameters even more simple. The operator can now begin the milling process with a push of two buttons.

But what if you require new technical specification for your dog bone samples or perhaps even other CNC machining specifications? The of this tensile preparation software is that it allows to save ANY parameters in the database for ease of access, no matter how simple or complex. The bottom line is that you will always be 2-3 buttons away from achieving your accurate tensile sample preparation results.

What is the longest tensile specimen that you can prepare with your TensileMill CNC?

The classic TensileMill CNC flat tensile specimen preparation machine can accommodate parts of (X by Y by Z) 10.6 by 10.6 by 6.3" dimensions. The versatility of this classic tensile sample preparation machine allows for medium to high tensile sample volumes. The Y travel along with custom tool fixtures offered standard with the classic unit allow for stacking capabilities to increase your tensile preparation output. Contact us to learn more.

Sample preparation problems? Introducing . . . the new TensileMill MINI

The struggle of accurate tensile test specimen preparation with manual or regular CNC machines has been ongoing amongst various manufacturing, education and government organizations. The top earning engineers spend 80% of their time preparing samples for tensile testing purposes. The sad statistic is that "preparing tensile samples" output only amount to 20% of the required output for companies to justify salaries and profitability. It is about time for the tables to turn. What if only 20% of the time was spent on preparing the samples? What if the samples were prepared accurately to specifications every single time by any experience level operator? This would be a game changer, wouldn't it?

Introducing the new and improved TensileMill MINI!

With a 24,000 RPM ISO20 spindle and high-powered servos, this little powerhouse of a machine is not only cost-effective, but a game-changer for your medium volume tensile sample preparation needs.

Set and Go

In the past, special operator skills made for costly labor and the possibility of serious errors that were difficult to catch. The MINI allows specific samples to be set easily with little user skill or time involved, ensuring consistency and better end results. This is done with our superior TensileSoft™, a tensile specimen software that allows to produce results in seconds with a push of a few buttons.

Time Saver

When volumes and demand are high, there's no time to waste. The time-saving TensileMill MINI operates at enhanced speeds on a powerful carbon software system that can be customized to meet any ASTM, DIN, ISO, or other standards. Imagine having your samples be prepared by 50%, 100% or 600% less time than with the traditional methods. This is the unique value that the MINI brings to the table.


Short on space? There's no better compact unit on the market than the TensileMill MINI. The small dimensions allow minimal lab space requirements while still creating high quality tensile specimens as needed.


When it's all said and done, precision is the most important aspect your customers are concerned with. The required industry standards imposed on virtually all manufacturing, education and government facilities are exact and have minimal error margin allowances. The MINI's enhanced accuracy and consistency in tensile test sample preparation makes it an exciting new solution. No one offers more consistent uniformity in samples, while meeting all standard requirements. This means that you can rest assured that your machine will mill the samples to required industry standards every time, whether you are milling a single sample or stacking samples for efficiency.


With standard interfaces such as touch screen, USB ports, and system storage ports, operators will find the machine easy to use and efficient in getting their job done. The user-friendly software interface allows operators to simply enter the requirements and let the machine do the rest with just a push of the button.


Have special considerations that need to be met? In addition to standard software, the MINI can be upgraded to various tools and work offsets, and MACH4 Industrial CNC software. No matter what your unique application is, by simply letting us know, our engineering team will work its magic to accommodate it!

What is the TensileMill CNC?

The TensileMill CNC is a robust machining center that can be positioned on your production floor or in your laboratory.
