TensileMill CNC
Classic Upgrade
Flat Specimen Preparation

The Classic Upgrade is TensileMill CNC’s flat tensile and impact specimen preparation machine built for ease of use, based on the original flat-specimen platform. It balances capacity and footprint for everyday lab and production work.

It is a proven, well-rounded choice for in-house flat preparation. Explore where it fits and compare the flat models.

Its core specifications include:

• Working / traveling area: 15.75 × 15.75 × 8 in (400 × 400 × 200 mm)
• Gantry clearance: 7.87 in (200 mm)
• Heavy-duty fully cast body and frame on casters

The rigid cast frame is what keeps tolerances stable cut after cut. To confirm it suits your specimens, talk to a specialist.

It is built around high-quality motion components:

• 3.2 kW water-cooled spindle at 24,000 rpm, ER20 collet (ISO20 optional)
• FANUC servo motors with high-precision PMI ball-screw drives and Japanese NSK bearings
• FANUC 0i-MF Plus controller with a 10.4 in touchscreen

Premium drives and bearings are what hold tight, repeatable geometry. To confirm the configuration, request a personal quote.

It holds positioning accuracy of ±0.13 mm and repeatability of ±0.02 mm, with traverse speeds to 10,000 mm/min, a feed rate of 1 to 3,000 mm/min, and coolant flow of at least 20 L/min. Repeatable geometry keeps your tensile and impact results comparable.

Low scatter starts with a consistent specimen. Learn more about our standards and certification.

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.

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.

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.

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.

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.

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.

Yes. The cast body sits on casters, so it can be repositioned within the lab as needs change. Its self-contained design fits standard lab and production layouts without special facilities.

Mobility makes it easy to fit into an existing workflow. To discuss placement, talk to a specialist.

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.

The Classic Upgrade requires a 220 V three-phase supply and 52 A. Total rated power is 12.5 kW.

The voltage tolerance is 200–240 V.

To confirm your site requirements, talk to a specialist.

A 3-prong, 52 A receptacle. Plug the machine into the receptacle, or hardwire it to the terminal in the lower left corner of the electrical panel.

To plan the electrical installation, talk to a specialist.

No. The machine is equipped with standard recirculating coolant and way lube systems, so no water connection is required.

The Classic Upgrade is a floor-standing system and can be installed to suit your layout. As an option, we recommend tilting the machine slightly towards the right front side to improve fluid circulation.

To discuss placement in your lab, talk to a specialist.

Yes. The machine requires a compressed air connection with a 10 mm OD hose. The supply pressure should be between 86 and 116 psi (5.9–8.0 bar).

To confirm your site requirements, talk to a specialist.

The suggested floor area (L × W) is 72 × 72 in (1,829 × 1,829 mm).

With the door closed, the machine measures 59 × 53 × 79 in (1,500 × 1,350 × 2,000 mm) and weighs 2,640 lb (1,200 kg). The cast body sits on casters, so it can be repositioned when needed.

To confirm it fits your floor plan, talk to a specialist.

The Classic Upgrade is equipped with an internal recirculating fluid chamber. Change the fluid every 6–12 months.

As a general rule, the spindle cooling fluid only needs to be changed once a year, and the cutting fluid should be topped up when it gets low. Recommended coolant brands include Cimcool, Hocut and Blaser.

For coolant and tooling supplies, explore our consumables and spare parts.

Yes. The TensileMill CNC Classic Upgrade requires distilled water for its machining coolant system.

For maintenance questions, talk to a specialist.

The Classic Upgrade comes standard with a way lube system; the lubricating oil is purchased separately. Use ISO 68 equivalent way lube. Suitable brands include Mobil, Shell and Irving.

For a maintenance checklist, talk to a specialist.

The Classic Upgrade comes standard with a triple sample fixture, designed to maximize throughput and minimize operator time. It holds three samples, or three sample stacks, of up to 1.5 in (38 mm).

The operator selects a preset in the software, starts the machine and moves on to other work while the specimens are prepared.

The clamping set includes regular, sub-size and large clamps, configured to your requirements as part of the Turnkey Solution Package.

To match fixtures to your specimens, request a personal quote.

Yes. The clamping fixture doubles as an impact specimen preparation fixture for 10 × 10 × 55 mm and 7.5 × 10 × 55 mm specimens. It holds up to 8 samples at once and saves up to 90% of preparation time.

Starting blank dimensions for rectangular impact specimens:

• 10 × 10 × 55 mm, width and thickness: 11.5–15.5 mm (0.45–0.61 in)
• 10 × 10 × 55 mm, length: 56.5–61 mm (2.22–2.40 in)
• 7.5 × 10 × 55 mm, 10 mm side: 11.5–15.5 mm (0.45–0.61 in)
• 7.5 × 10 × 55 mm, 7.5 mm side: 9–15.5 mm (0.35–0.61 in)
• 7.5 × 10 × 55 mm, length: 56.5–61 mm (2.22–2.40 in)

The starting width and thickness of the stock do not need to be the same.

To confirm impact geometries, request a personal quote.

The Classic Upgrade comes standard with a FANUC controller with the integrated TensileSoft 2.0 package, operated from a 10.4 in touchscreen (FANUC 0i-MF Plus).

This integration is the world’s first to provide a user-friendly tensile and impact specimen preparation procedure, suited to both inexperienced and experienced CNC machinists.

To see the software in action, talk to a specialist.

The Classic Upgrade comes standard with an end mill recommended for your material as part of the Turnkey Solution Package. Softer materials need different end mills than harder ones, so our engineers recommend tooling based on the material type, its hardness and your milling volume.

TensileMill end mills are designed specifically for tensile specimen preparation and last longer than comparable end mills. Buy them from TensileMill CNC Inc. or through your preferred local tooling distributor.

Explore our consumables and spare parts.

Apart from end mills, the spindle may need replacement after a few years of heavy use.

Most spare parts and consumables are available in-house or can be delivered within days to a few weeks.
