Overview
General
TensileMill CNC MINI – Compact Flat Tensile Test Sample Preparation is better than ever. Do not let the apparent “size” of the unit full you. This mini mill is specifically design for the ultimate flexibility in tensile specimen preparation as well as full CNC machining capabilities. Since the latest upgrades to the system, the MINI is now superior to our Classic model by virtually all parameters. You can now benefit from a smaller foot print, larger table size, higher power, and better precision & repeatability all for a lower price! It has never been easier to prepare high quality tensile specimens with ease. Our TensileMill CNC MINI comes standard with a 21″ LCD screen equipped with our famous Tensile Software. The machine 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. Despite the small size of this machine, the standard 2.2kW (3hp) Water Cooling Spindle along with our designated tooling can prepare soft, hard and Inconel materials in large volumes. Transform inexperienced CNC machinists into proficient operators in just hours, eliminating the training and re-training issues commonly found in quality control departments. 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 MIN – Compact Flat Tensile Sample Preparation machine you may also upgrade to our Carbon software interface, making this unit a hybrid of tensile sample and a CNC machine. Our intuitive and powerful CNC control system comes with virtually endless possibilities.Technical Specifications

What is the TensileMill CNC MINI?
The TensileMill CNC MINI is a compact, high-power machine for flat tensile and impact specimen preparation. It combines a smaller footprint with a larger table, and prepares specimens compliant with ASTM, ISO, DIN, and JIS methods.
It brings full in-house preparation to labs that are short on floor space. Explore where it fits and compare the flat models.
What makes the MINI different from the MICRO?
The MINI pairs a smaller overall footprint with a larger 400 × 400 mm table and a higher-speed 24,000 rpm water-cooled spindle, so it handles a wider range of coupons at higher throughput than the MICRO.
It is the step up when you need more table and power without a big floor area. To compare models, compare the flat models.
What working area and size does the MINI have?
The key dimensions are:
- Working / traveling area: 15.75 × 15.75 × 7.87 in (400 × 400 × 200 mm)
- Machine size: 44.5 × 42.0 × 70.0 in (1,130 × 1,066 × 1,778 mm)
- Weight: 1,500 lb (680 kg)
The larger table takes bigger blanks while the footprint stays compact. To confirm it fits your space, talk to a specialist.
What spindle and drive system does the MINI use?
The MINI runs a water-cooled spindle rated 2.2 kW (3 hp) at 24,000 rpm, with an ER20 collet (ISO20 optional). Motion uses a FANUC servo of 0.54 hp (400 W) with 566 oz-in (4.0 N·m) torque and a maximum feed rate of 500 ipm (12.7 m/min).
A water-cooled spindle holds speed steadily through long runs. To confirm configuration, request a personal quote.
Which standards can the MINI prepare specimens to?
It prepares flat tensile and impact specimens to the widely used methods, including:
- ASTM E8 / E8M
- ISO 6892-1
- DIN 50125
- JIS Z 2241
ASTM E8 covers room-temperature tension testing of metallic materials, reporting yield strength, tensile strength, and elongation, all of which depend on accurate specimen geometry. Custom geometries are supported as well. See our standards and certification.
Can I upgrade the MINI spindle or servo?
Yes. Available upgrades include an ISO20 spindle taper for heavier tooling and a 3-axis servo package for smoother, more precise motion. These options tailor the machine to higher-demand work.
Matching the options to your workload protects finish and throughput. To scope upgrades, request a personal quote.
Can the MINI prepare impact specimens as well as tensile?
Yes. The machine is engineered for both tensile and impact specimen preparation, so one system covers both needs. Charpy impact testing under ASTM E23 measures the energy a notched bar absorbs when broken, which characterizes toughness and is sensitive to notch accuracy.
A rigid CNC platform delivers exactly the repeatable notches that impact testing needs. To confirm impact geometries, request a personal quote.
Do I need a trained CNC machinist to run the MINI?
No. A guided touchscreen workflow generates the machining path automatically, so an operator produces test-ready specimens without any prior CNC programming experience. The TensileSoft interface walks through setup step by step, with saved specimen profiles for fast, repeatable jobs.
This keeps specimen preparation with your lab staff rather than a machine shop. To arrange operator training, talk to a specialist.
What materials can the MINI prepare?
It prepares flat specimens from the common structural materials, including steels, aluminum, and other metals and alloys. Different materials cut differently, so matched end mills keep the finish clean and the tooling long-lived.
The correct tooling protects gauge quality on both soft and hard materials. Explore our consumables and spare parts.
What is included with the MINI?
It ships as a turnkey system, ready to run with:
- Tooling and clamping fixtures
- TensileSoft software
- Installation and operator training
You set up, calibrate, and start preparing specimens with minimal lead time. To confirm what ships with your configuration, request a personal quote.
What software controls the MINI?
The machine runs from the TensileSoft touchscreen, where the operator selects saved specimen profiles for each geometry. The interface generates the toolpath automatically, so no CNC programming is required.
Saved profiles keep every specimen consistent from one run to the next. To see the software, talk to a specialist.
Can I try the MINI on my own material first?
Yes. TensileMill CNC offers a free proof of concept, where you send your material and specimen requirements and receive a prepared sample set made on the actual system. This lets you confirm geometry, finish, and repeatability before you invest.
Seeing real results on your own stock removes the guesswork. To arrange a proof of concept, talk to a specialist.
How do I get a quote for the MINI?
You can request a personal quote at any time. Sharing your specimen sizes, materials, standards, and volume lets us confirm the right configuration and options.
For a tailored recommendation, request a personal quote.
RELATED TO STANDARDS
More standards can be added on-site with licensed TM Software, no specialist training required.
Your team can extend the machine to new test standards at any time using the machine's licensed TM Software, without CNC programming experience or outside help.
