TG-01 CNC Three-Axis Dumbbell Specimen Preparation Machine for Tubular Materials

The CNC universal specimen‑making machine employs numerical control technology, using a programmable controller to coordinate a three‑axis linkage system that drives the XYZ‑axis motors and is complemented by a high‑speed spindle motor, forming a high‑precision milling system. It enables the cutting of non‑metallic sheet specimens into strips, the milling of dumbbell‑shaped specimens, and the machining of impact‑notch grooves. First, the shapes of the specimens it produces are not constrained by the machine; as long as a program is provided, it can fabricate specimens of various forms—rectangular, dumbbell‑shaped, circular, or any irregular geometry—unlike conventional universal specimen makers, which are limited to rectangular and dumbbell‑shaped samples and can only produce dumbbell‑shaped specimens that match pre‑defined templates. Second, its precision is exceptionally high: whether cutting strips or milling dumbbells, the maximum machining error is just 0.05 mm. Third, it is virtually unrestricted by the geometry of the specimen; as long as the specimen can be securely clamped on the worktable, machining is possible—for example, dumbbell‑shaped specimens can be cut directly from a large plate, strips can be cut from any location on a sheet, and oversized or non‑conforming strips can be milled to size. During operation, for simple rectangular non‑standard strips, a manual cutting mode may be used; for dumbbell‑shaped or other standard specimens, the company provides commonly used standard machining programs that can be activated directly from the controller. For users requiring custom‑shaped specimens, the company also offers programming services. In addition to specimen fabrication, this machine can be expanded to perform a wide range of other machining tasks.
