Description
Product Introduction:
The CNC universal sample preparation machine employs CNC technology, utilizing a programmable controller to manage a three-axis linkage system that drives the XYZ‑axis motors, complemented by a high-speed spindle motor, thereby forming a high‑precision milling system. This enables the cutting of non‑metallic sheet material into test strips, the milling of dumbbell‑shaped specimens, and the machining of impact notches.
First, the shape of the specimens it produces is not constrained by the machine; as long as a program is provided, it can fabricate specimens of various forms—rectangular, dumbbell‑shaped, circular, or even irregular geometries—unlike conventional universal specimen‑preparation machines, which are limited to rectangular and dumbbell‑shaped samples and can only produce dumbbell‑shaped specimens that match the dimensions of the corresponding dies. Second, its precision is exceptionally high: whether cutting strips or milling dumbbells, the maximum machining error is only 0.05 mm. Finally, it is virtually independent of the specimen’s geometry; as long as the specimen can be securely clamped on the worktable, processing is possible—for example, dumbbell‑shaped specimens can be cut directly from a large plate, strips can be sectioned from any location on a sheet, and strips that do not meet dimensional specifications can be milled to size.
When operating this machine, you can use manual cutting for simple rectangular non‑standard specimens. For dumbbell‑shaped or other standard specimens, we provide pre‑configured standard‑specimen machining programs that can be directly launched from the controller. For customers requiring custom‑shaped specimen fabrication, we also offer programming services. In addition to specimen machining, this machine can be expanded to support a wider range of processing applications.
Product Features:
1. High machining accuracy and fast speed.
2. Machining multiple spline profiles in a single operation. For example, on the same workpiece, dumbbell‑shaped, rectangular, and circular profiles can all be machined in one pass.
3. Equipped with a water-cooling function for materials. During processing, any material that melts due to heat can be cooled using cooling water.
4. Machining compensation function: It can compensate for errors arising from thermal expansion of the material and compression during machining.
a) A dumbbell‑shaped specimen preparation procedure that covers all common materials; simply select the appropriate program to complete the preparation of the corresponding specimen.
b) Rectangular spline specimen preparation function, suitable for producing impact splines, thermal deformation splines, Vicat specimens, and other rectangular test specimens of various specifications.
c) Notch‑making capability: multiple specimens can be stacked on the platform and processed simultaneously. Different notch specifications can be achieved by changing the cutting tool.
d) Sheet‑cutting function: cuts larger sheets into smaller pieces.
e) Pipe cutting function.
f) Milling flat surfaces and milling vertical surfaces, used to machine irregularly shaped materials or portions removed from an entire component into flat plates, which can then be further processed into the required test specimens.
Processable graphics:
1. Dumbbell‑shaped spline machining. Supports the production of virtually all standard dumbbell‑shaped splines. The dumbbell‑shape program is built into the software; users can select the machining operation via the interface, eliminating the need to write their own programs. The system is simple to operate and easy to learn. Custom programs for special shapes can be developed upon request from the manufacturer.
2. Rectangular spline machining. The most common type is an impact spline measuring 80 × 10. In the software, select the rectangular machining option, enter the rectangle’s length and width along with any other required parameters, and then proceed with the machining process.
3. Circular specimen machining. The most commonly used is the circular specimen for Vicat softening temperature testing. In the software, select the circular machining option, enter the circle’s diameter and other required parameters, and then proceed with the machining process.
4. Straight-line cutting. The cutting operation can be controlled manually, or the straight‑line machining function in the program can be used to cut the sheet material.
5. Notch machining. Specimens used for simply supported beam or cantilever beam impact tests typically require standard notches. This machine is equipped with standard notch milling cutters of R0.1, R0.25, and R1.00, enabling the milling of three standard notch types on the specimens.
6. Plane milling: Irregularly shaped workpieces can be milled into flat surfaces. In the software, select the plane‑milling operation, specify the length and width of the milling area, and set the desired thickness; the plane‑milling function will then be executed.
