Description
The TensileMill CNC XL – Flat Tensile Specimen Preparation Machine is an advanced and powerful CNC machining system designed for laboratories and production environments that require high-volume, precision sample preparation. As an enhanced version of the classic TensileMill CNC model, the XL system delivers extended table dimensions, greater travel distance, and increased spindle power—making it ideal for processing larger or tougher materials while maintaining exceptional dimensional accuracy.
Equipped with a high-speed spindle and precision servo motors, the TensileMill CNC XL achieves fast material removal rates and consistent surface finishes across steel, aluminum, composite, and polymer specimens. The system operates on the Mach4-based control platform, which supports complex machining programs and allows users to create custom pockets, contours, hole patterns, and engraved markings directly from the touchscreen interface.
Despite its industrial-grade performance, the TensileMill CNC XL maintains a compact footprint, making it suitable for both research facilities and production floors. The intuitive TensileSoft™ interface enables users with minimal CNC experience to select or customize ASTM-, ISO-, or DIN-compliant parameters for immediate machining. The result is a fully automated, turnkey solution that prepares flat tensile specimens with repeatable accuracy and minimal operator involvement.
From light sheet metals to heavy-duty alloys, the TensileMill CNC XL offers a scalable solution for any laboratory looking to improve throughput, shorten lead times, and maintain strict compliance with global testing standards such as ASTM E8, ASTM A370, ISO 6892-1, and DIN 50125.

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.
