This system supports machining flat tensile specimens to ASTM E8 geometries and blanking Charpy/Izod impact bars to ASTM E23, and it also accommodates ISO 6892-1, DIN 50125, and JIS Z2206 specimen families; U- and V-notch ready bars can be produced when the machine is paired with the companion notcher.

On tensile work, ASTM E8 is the common reference for metallic flat tensile specimen geometry in North American labs, while ISO 6892-1 and DIN 50125 cover international and German nominal specimen shapes. In practice technicians use the CNC mill to cut full- and sub-size flat specimens and to reproduce custom geometries so the finished blanks fit the grips and extensometer setups used in your tensile frames.

For impact testing, ASTM E23 defines Charpy and Izod specimen sizes and notch requirements; this system produces impact blanks to the required cross section and length, and the companion notcher produces U or V notches per the method. JIS Z2206 is the equivalent Japanese standard that some customers follow for notch geometry and bar dimensions.

The machine also supports batch and multi-specimen workflows and custom milling programs, which labs commonly use to blank dozens of tensile specimens or multiple impact bars in a single setup before notching and final testing.

Accuracy and repeatability come from three practical areas: a mechanically stable machining platform, predictable tooling and motion control, and repeatable setup/workflow through software and fixtures. The machine’s heavy frame and precision motion components hold cuts steady, the spindle and toolpath strategy deliver consistent finished geometry, and the control software plus multi-part fixtures let operators reproduce the same offsets and sequences every run.

Mechanical stability: the mill uses a rigid cast-iron base and precision linear guidance with preloaded screw drives and quality bearings so the axes move the same way from part to part. That stability keeps the gauge section centered and prevents dimensional drift when you run several cycles in a row.

Motion and tooling control: a water-cooled spindle with an ER collet and purpose-built feeds and finish passes reduces runout and tool deflection. Operators use a light finish pass and controlled coolant flow to hold surface finish and final width, which lowers variability in fracture behavior and tensile results.

Repeatable fixturing and probing: the system accepts multi-specimen fixtures that clamp blanks outside the gauge area, plus soft-jaw or nest-style locating that eliminates part-to-part mislocation. Built-in probing and saved work offsets let the controller check alignment and automatically compensate for tool length or minor stock variations before the program runs.

Software and process control: a template library for standard specimen geometries lets the lab store exact toolpaths, feeds, and finish-pass parameters for ASTM and ISO tensile profiles, so technicians load the same program each batch. The controller logs program IDs, offsets, and cycle records for traceability and makes it straightforward to repeat an approved setup on future lots.

Planned maintenance and environmental measures also matter: automatic rail lubrication, a spindle chiller and consistent coolant practice reduce wear and thermal change, and a routine PM schedule preserves the initial alignment and repeatability of the machine over time. In practice labs fixture batches of 6–8 blanks, run the saved template, then verify a sample or two with a caliper or bench micrometer to confirm the batch before testing.

Yes, the Classic Upgrade will machine both flat tensile specimens and Charpy/Izod impact blanks on the same platform. It produces standard flat tensile profiles and the common Charpy/Izod impact blanks, and when paired with a motorized impact notching or broaching unit it supports U- and V-notch preparation to impact test requirements.

The unit handles standard impact blank sizes, including 10 × 10 × 55 mm and 7.5 × 10 × 55 mm, and accepts flat tensile geometries from common metallic standards. Its working envelope accommodates specimens up to about 14 inches (350 mm) long, 2 inches (50 mm) wide, and 0.5 inches (12.5 mm) thick, and the product literature cites surface finish tolerances below 75 Ra and the ability to machine materials up to about 60 HRC.

The usual workflow in labs is to run rough and finish milling for all blanks on the TensileMill CNC, then move impact blanks to the motorized notcher for controlled U- or V-notch formation; the notcher can notch one or two samples at a time depending on configuration. For higher throughput the Classic Upgrade supports multi-sample operation and fixtures such as a triple clamping fixture, which lets technicians prepare stacked specimens or batches before final notching and testing, a practical approach for QC or R&D runs.

This system accepts single-piece blanks up to 14 in (350 mm) long, 2 in (50 mm) wide, and 0.5 in (12.5 mm) thick as the maximum specimen dimensions.

The available machining envelope and clearances govern those limits: the working/traveling area is 15.75 × 15.75 × 8 in (400 × 400 × 200 mm), gantry clearance is 7.87 in (200 mm), and spindle nose clearance is 1.97 in (50 mm). These values determine how you orient and fixture longer or odd-shaped blanks during setup.

Note that the single-piece thickness limit remains 0.5 in; however, with the optional triple clamping fixture you can prepare multiple parts in one cycle, specifically up to three stacked sets of 1.0 in (25 mm) thick specimens for higher throughput.

This system machines metallic tensile and Charpy/Izod impact specimens across the typical laboratory range, from soft/ductile metals up through hardened steels with a hardness up to 60 HRC, and it supports the standardized specimen geometries used for tensile and impact testing.

Put simply, the unit is rated for metallic materials up to 60 HRC, so you can process materials commonly found in QA and R&D labs such as aluminum and copper alloys, stainless and low-alloy steels, and tool or tool-hardened steels whose hardness does not exceed 60 HRC; this capability aligns with ASTM E8 tensile specimen geometries.

The machining envelope and fixturing determine what you can load at once: the system accepts specimens up to 14 inches (350 mm) long, 2 inches (50 mm) wide and 0.5 inches (12.5 mm) thick, and a triple-clamp option lets you stack multiple parts for higher throughput (the product page notes up to three stacked 1.0 inch sets in a single setup). Positional repeatability is in the sub-thousandth-inch range, which helps keep gauge sections and shoulders within tight dimensional tolerances.

For Charpy/Izod work the machine prepares standard impact blanks (for example 10×10×55 mm and 7.5×10×55 mm), can deliver surface finishes below 75 Ra for reliable impact results, and is typically paired with an impact notching/broaching unit for final U and V notches per ASTM E23.
