Overview
General Description
The TensileMill CNC MICRO is a compact, 2-axis machining system designed for preparing flat tensile and impact test specimens from metal, plastic, and composite materials. The system is suitable for laboratories and production environments where precise specimen geometry and consistent repeatability are required, but the volume of samples does not justify a full industrial CNC machining setup. The MICRO uses a guided touchscreen interface and a dedicated workflow tailored specifically for specimen preparation. This allows technicians without prior CNC experience to produce accurate, test-ready specimens with stable dimensional results. Custom baseplates and tensile jigs allow the MICRO to machine both sides in a single machining cycle without re-clamping, helping maintain symmetry while minimizing operator involvement. With its enclosed work area, integrated flood coolant recirculation system, and mobile base, the MICRO operates as a self-contained unit that fits efficiently into laboratory layouts. The system supports both standardized geometries and custom specimen dimensions, making it suitable for QA/QC teams, R&D facilities, educational institutions, and manufacturers conducting mechanical testing.Application and Use Cases
The TensileMill CNC MICRO is used for preparing flat specimens required for tensile and impact testing. Laboratories and testing facilities need to create specimens with the same shape to get trustworthy test results, and the MICRO helps achieve this by making consistent shapes within specific size limits. The system is applied in QA/QC workflows, material qualification, research and development programs, and educational testing environments. It is suitable for metals, plastics, and composite materials processed in sheet or strip form. The MICRO can handle both standard sizes set by ASTM and ISO standards and special shapes defined by internal testing rules. The machine is most commonly integrated into testing workflows where:- mechanical properties need to be verified as part of production or batch release;
- research teams evaluate new alloys, polymers, or composite formulations;
- educational and training labs prepare specimens as part of academic instruction;
- outsourcing specimen preparation results in inconsistent geometry or delayed turnaround.
Key Features
- 2-Axis Simplicity: Operates along X and Y axes, smoothly cutting both sides in one machining cycle.
- Stack blanks up to 0.5 inches thick under the tensile jig – produce either one thick specimen or multiple thinner specimens in a single run.
Key Advantages
This machine offers several practical advantages for preparing flat tensile and impact specimens across laboratory and production testing environments. Key advantages include:- Purpose-built for flat specimen preparation rather than adapted from a general-purpose CNC system.
- Dimensional repeatability up to ±0.02 mm, supporting consistent mechanical test results across batches.
- Guided touchscreen workflow allows operation without prior CNC programming experience.
- Custom baseplates and tensile jigs enable two-sided machining in one cycle without re-clamping, helping preserve alignment and symmetry.
- Compact, enclosed, and self-contained layout supports installation in laboratory environments.
- Suitable for both standardized geometries and custom specimen dimensions.
TensileSoft Interface
With TensileSoft, the machine programs itself. The operator simply inputs specimen details, selects the material, and the MICRO generates the machining path automatically. The system is operated through the TensileSoft interface on an integrated 15.6″ touchscreen. The workflow is structured to guide the operator through specimen setup and machining without requiring CNC programming experience. Key functions include:- Selection of standardized specimen geometries or entry of custom dimensions.
- The machine provides guided prompts for blank alignment and fixture clamping
- The system generates the machining path automatically based on specimen details and material selection.
- Saving and recalling previously used specimen profiles for repeat work.
Specimen Capabilities
- Prepares specimens up to 8 inches in length.
- Compatible with 4-inch and 8-inch tensile jigs for versatile sample prep.
Workflow Efficiency
Custom baseplates and jigs allow seamless cutting of both sides without re-clamping. Load, start, and let the MICRO handle the rest, efficiency and precision in one. The TensileMill CNC MICRO delivers repeatable, accurate results, an ideal addition to any lab or production floor streamlining tensile specimen preparation.Technical Specifications

What is the TensileMill CNC MICRO?
The TensileMill CNC MICRO is a compact, highly efficient machine for precise flat tensile and impact specimen preparation. Its self-contained design fits neatly into existing lab and production layouts without a dedicated machining area or special facilities.
It puts repeatable, lab-grade specimen preparation within reach of any operator. Explore where it fits and compare the flat models.
Who is the MICRO best suited for?
It suits labs that need precise flat specimens in a small footprint, especially where space is tight or volumes are low to medium. Because the workflow is fully guided, it is ideal for teams without a dedicated CNC machinist.
Compact size makes in-house preparation practical even in a crowded lab. For a fit check, request a personal quote.
What working area and size does the MICRO have?
The key dimensions are:
- Working / traveling area: 8.27 × 4.72 × 0.79 in (210 × 120 × 20 mm)
- Machine size: 20.5 × 24 × 59 in (52 × 60 × 150 cm)
- Weight: 1,500 lb (680 kg)
The compact envelope is what lets it sit in a standard lab space. To confirm it fits your floor plan, talk to a specialist.
What spindle and power does the MICRO use?
The MICRO runs an air-cooled spindle at 18,000 rpm with a 3.5 kW motor, fed by recirculating flood coolant and an ER25 collet. It connects to a 220 V single-phase supply at 3.3 kW (15 A).
Flood coolant and a high-speed spindle protect edge quality on thin coupons. To confirm site requirements, talk to a specialist.
How accurate and repeatable is the MICRO?
The MICRO holds positioning accuracy of ±0.03 mm and repeatability of ±0.02 mm, with traverse speeds up to 8,000 mm/min and a feed rate of 1 to 3,000 mm/min. Because tensile results are calculated from the specimen’s cross-section, this repeatable geometry keeps test scatter low.
Consistent geometry batch after batch is the foundation of comparable data. Learn more about our standards and certification.
Which standards can the MICRO 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 the MICRO 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 MICRO?
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 MICRO 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 MICRO?
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 MICRO?
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.
Is the MICRO safe to run in a lab?
Yes. It comes with a full safety enclosure and a mobile stand with an integrated coolant tank, so cutting, chips, and coolant stay contained. This suits shared lab and production spaces.
Enclosed cutting keeps operators and nearby work protected. To discuss placement, talk to a specialist.
Can I try the MICRO 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 MICRO?
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.
