TensileMill CNC XL – Flat Tensile Specimen Preparation Machine
Metal Testing Equipment
Standards
Description
The TensileMill CNC XL is the large-capacity machine in the TensileMill range, built for laboratories and production floors that prepare flat tensile specimens in volume. Against the classic model it adds table size, travel and spindle power, which is what lets it take longer specimens and tougher material without giving up dimensional accuracy.
A high-speed spindle and precision servo motors hold the feed steady through steel, aluminum, composite and polymer specimens, so the surface finish stays the same from the first specimen of a batch to the last. The machine runs on the Mach4 control platform, which accepts full machining programs: custom pockets, contours, hole patterns and engraved markings are all set up from the touchscreen.
Compliance is the point of the exercise. The TensileSoft™ interface holds the geometries of ASTM E8, ASTM A370, ISO 6892-1 and DIN 50125, so an operator with little CNC experience selects the standard, enters the material, and machines a specimen that matches the drawing in the method.

TensileMill CNC XL Features
The XL is a 30-taper machining center underneath, and that is what the specimen work rides on: rigidity first, then speed.
Heavy-duty construction
A rigid cast iron frame on linear guideways runs without vibration at high spindle speed.
Precision drive system
20 mm ball screws on X and Y, 25 mm on Z, for smooth motion and repeatable positioning.
Servo spindle
A belt-driven 5 hp (3.7 kW) servo spindle to 10,000 RPM with a BT30 taper removes material efficiently in metals and composites.
Tool control
Full synchronous position control, disc-spring clamping, a collet-style gripper and air-over-hydraulic release make tool changes fast and secure.
Automatic tool changer
A 10-station umbrella changer with any tool assignable to any position.
Integrated CNC center
An ergonomic control panel, a large touchscreen and an MPG handwheel for manual adjustment.
Mach4 software
Mach4 control software, compatible with Fanuc G-code and Macro B, with graphical wizards for on-machine programming.
Industrial PC
A 5th-generation 64-bit Intel Broadwell processor, 64 GB SSD and 4 GB RAM run the programs.
Connectivity
Wi-Fi and Bluetooth for data transfer and remote monitoring.
Controller and Software
The touchscreen controller runs the Carbon™ CNC software suite. It carries macro B programming, helical interpolation, drilling canned cycles and dual-mode cutter compensation, which is what makes the more complex specimen geometries possible, and it keeps both environments a tap apart: TensileSoft™ for specimen preparation, Mach4 Industrial for general machining.

Service Plan and Support
NextGen Material Testing offers a service plan for every TensileMill CNC system. The point of it is that the machine keeps producing specimens that meet the standard years after installation, which is a calibration question as much as a maintenance one:
- Scheduled preventive maintenance, so problems are found before they stop the machine
- Operator training and retraining, so the team uses what the system can do
- Performance verification and calibration checks against ASTM, ISO and DIN requirements
- Priority technical assistance for troubleshooting, software updates and replacement parts
Tell us your testing schedule and we will put a plan together around it.
TensileMill CNC XL Technical Specifications

* Accuracy and Repeatability Disclaimer: Published accuracy and repeatability values are based on proper machine setup, recommended tooling, operational procedures, maintenance practices, material conditions, and validated proof-of-concept parameters. Actual performance may vary depending on material type, hardness, specimen geometry, tooling selection, fixturing, machine workload, operator practices, production conditions, and adherence to recommended operational protocols. Operation outside of recommended procedures or intended application parameters may affect achievable accuracy, repeatability, equipment longevity, and overall system performance.

FAQs
If you want to pinpoint the exact quantity of specimens that can be prepared in one cycle, we advise that you speak with one of our Product Consultants to further discuss your application. Flat tensile mill quantity samples and the time it takes to complete the machining process will usually depend largely on the material type, the hardness, and the thickness of your material. Submit your request or call us today for any additional details!
The TensileMill CNC XL will be supplied with all of your necessary end-mills and tooling fixtures for any long term operations. Additional fixtures can be very easily acquired from TensileMill CNC. Request a quote today.
Even though the tooling fixtures are designed to last a lifetime with the proper maintenance, if you wish too, additional fixtures can also be purchased along the road.
The capacity offered by TensileMill CNC XL is better and more superior than both the Classic and the MINI. The machine offers a much bigger and better frame which is capable of handling tougher and larger samples. The standard tool charger allows for automation of tensile sample preparation needs. The unit is able to be programmed for tensile sample preparation and for advanced CNC machining requirements with the on-of-a-kind software that comes standard with the unit.
The longest Tensile specimen that can be prepared using the TensileMill XL will depend with the working travel distance of (X by Y by Z) 15.75 by 15.75 by 9.1. This machine is ideal for dynamic and skillful tensile sample preparation. The unit can handle large stacking volumes of various material hardness with ease. If you have a laboratory which requires a high volume of tensile preparation, the XL will be the perfect fit for you. Request quote today to learn more.
The XL model is a versatile machine which offers the best of both worlds when it comes to tensile specimen preparation and general purpose CNC machining. The unit can be equipped with a few options for tensile clamping fixtures:
Double Clamping Fixture (Standard) TensileMill CNC XL comes with a standard double clamping fixture.
Technical Details:
This option offers you the ability to prepare 2 stacks of up to 12" long, 2" wide, and up to 1" thick (note that this depends on the material).
Triple Clamping Fixture (Upgrade):
The triple fixture is an upgrade option that is commonly used for specimen preparations for higher volume, regular, and/or sub-size specimen preparations.
Technical Details:
This option offers you the ability to prepare 3 stacks of specimens that go up to 12" long, 1" wide, and up to 1" thick (again this depends on the material). The side fixtures can also be removed to prepare a thicker specimen in the middle fixture. These offers add versatility to the user.
Custom Clamping Fixture:
Sheet metal fixtures, tube fixtures, and others are available based on your specific technical requirements. TensileMill CNC Inc. is also very capable of designing a specialty fixture based on your needs.
TensileMill CNC XL will in fact be supplied with all of your necessary end-mills and tooling fixtures for long term operation. Additional end-mills and fixtures can be easily acquired from TensileMill CNC requesting a quote today.
The tooling fixtures are designed to last a lifetime including proper maintenance, additional fixtures can also be purchased down the road.
Following the basic preventative maintenance procedures is the general rule for all quality control equipment. Keeping your unit clean and keeping the lube tank full is a little bit of a special recommendation. Contact us if you have any other questions.
The XLis a specialty unit which can be customized to your specific needs. The base price of the XL includes the turnkey solutions based on your technical requirements. Base fixtures, clamping fixtures, ER collets, End Mills, ISO 20 Spindle Upgrade and more are also a part of this upgraded version of the Classic unit.
