TensileTurn CNC
MINI
Compact Round Tensile Specimen Preparation

Yes. The TensileTurn CNC MINI prepares round tensile specimens to ASTM E8/E8M, ASTM A370, ISO 6892-1, DIN 50125, EN 10002 and other major standards. Operators select a pre-programmed geometry from the TensileSoft library or enter custom dimensions to match internal procedures. Our team can also help with configuration and certification documentation, and TensileMill CNC facilitates certification services for NADCAP, ISO and ASTM compliance.

No. TensileSoft is designed for operators without CNC programming experience. The operator picks a standard geometry or enters custom dimensions, loads the blank and presses start, and the software generates the toolpath automatically. A password-protected CNC mode remains available for experienced users who want to run their own programs.

The TensileTurn CNC MINI runs on a 220 V, 3-phase, 50/60 Hz supply, 16 A, with a total connected power of 6 kW. The machine is delivered without a plug and is hard-wired by a licensed electrician to a dedicated circuit. A compressed-air supply is also required for the pneumatic tailstock and the integrated air gun. No facility water line is needed, because the machine runs from its own 30 L internal coolant system. Your CNC consultant confirms the exact breaker size, receptacle and air requirements at quotation, based on your configuration and region.

Every TensileTurn CNC MINI includes operator training, delivered remotely or on-site depending on your preference, so your team prepares its first specimens with confidence. After installation, our support team assists with setup questions, new specimen geometries and troubleshooting, and every system receives software updates at no additional cost. Service Plans with preventative maintenance and retraining are also available.

The MINI is designed for the metals most commonly tested in round form, including carbon and alloy steels, stainless steels, aluminum and copper alloys, with a recommended material hardness of up to 35 HRC. It accepts round stock up to Ø90 mm (Ø3.54 in) in diameter and 280 mm (11.0 in) long, and produces finished specimens up to 250 mm (9.84 in). Square or rectangular starting material is not supported. For harder or difficult-to-machine materials, send us a sample through our Free Proof of Concept program and we will confirm the results before you order.

Surface finish depends on the material, tooling and cutting parameters. TensileSoft separates rough and finish passes and lets the operator set feed per revolution and surface speed, so the finish pass can be tuned for a smooth, consistent gauge section. For applications that require a polished surface, such as fatigue specimens, the MINI can be paired with our TensilePolish solution.

Overall dimensions are 1,350 × 700 × 1,300 mm (53.1 × 27.6 × 51.2 in) and the net weight is 354 kg (780 lb). The machine stands on its own cabinet base with the coolant tank inside, so no separate bench is required. Allow clearance around the machine for opening the front and side doors and for routine maintenance.

Yes. Through our Free Proof of Concept program, you send us your material and specimen requirements, and we machine a sample set on a TensileTurn system at no charge. We return the specimens with before and after photos and a video of the process, so you can validate dimensions and finish before you invest.

The MINI is a turnkey system. The standard package includes the machine with built-in 15.6″ touchscreen controller and TensileSoft, the 8-position electric turret delivered with all tooling pre-installed and recommended inserts for preparing tensile specimens, a Ø100 mm 3-jaw chuck, a pneumatic MT1 tailstock, a 30 L water-based flood coolant system with 40 W pump, a toolbox and a wrench set. Installation and operator training are included, and our team helps configure your first standard and custom geometries. A 4-jaw chuck is available as an option; please contact your TensileMill CNC consultant for details. Additional chucks and consumables are available from our online shop.

The MINI is the entry-level model, built for low-volume labs, education and research. It uses a built-in 15.6″ touchscreen with TensileSoft on a MachMotion M31 motion controller, 100 mm X and 175 mm Z travel, and a 100–3,000 rpm spindle. The Industrial Upgrade adds FANUC control integration, longer 180 mm X and 225 mm Z travel, a 50–3,500 rpm spindle and tighter published positioning accuracy.

The TensileTurn CNC MINI comes with a 12-month manufacturer’s limited warranty covering the main mechanical and electrical components: spindle, chuck, tailstock, timing belt and timing pulley, servo motor and servo drive, power supply and circuit breaker. Consumable tooling and inserts are not covered. Extended warranty options and preventative-maintenance Service Plans are available; talk to a specialist to match coverage to your test volume.

First production machines ship from January 2027. The standard lead time after order confirmation is 3 months. Pre-orders are open now and are fulfilled in the order they are received; contact your CNC consultant to reserve a production slot.
