Product Brief

Core Machine Advantages

1. Dual Optional Control Interfaces

   Customers can freely select touch HMI or physical button operation modes. The color touch panel features intuitive parameter input, real-time cycle display and one-click start/stop; the button panel delivers stable, cost-effective basic counting functions for simple test scenarios. Both versions support jog manual positioning for quick specimen alignment.

2. Fully Adjustable Flex Speed & Auto Cycle Stop

   Flex frequency ranges from 0–100 cycles per minute with stepless speed regulation via precision rotary knob. Users preset target test counts on the panel; the unit automatically halts once cycles reach the set value, eliminating manual timing supervision for long-duration fatigue tests.

3. Anti-Corrosion All-Metal Clamping Assembly

   All fixture frames, pressing wheels and guide components are manufactured from aviation aluminum and stainless steel with anti-rust treatment. Upper-lower dual pressing wheel design locks specimens firmly without slipping during thousands of flex cycles, guaranteeing consistent bending angle at every stroke (90°±2°).

4. Low-Vibration Precision Drive System

   Adopted high-torque silent servo motor matched with optimized crank linkage transmission. The whole machine runs smoothly with minimal noise even under full 12-piece load. Four height-adjustable rubber foot pads balance the equipment on uneven countertops and absorb operating vibration.

5. Robust Baked Paint Cabinet

   Thick cold-rolled steel cabinet with high-temperature electrostatic baking finish, scratch and chemical resistant. Compact overall layout occupies limited lab bench space while simplifying daily surface cleaning and maintenance.

Compliant International & Domestic Test Standards

Standard Test Operating Process

1. Prepare standard pre-notched test strips per corresponding material specifications, secure samples between upper and lower pressing wheel fixtures and fasten lock knobs.
2. Power on the machine, utilize jog mode to adjust bending arm to a neutral position, input target flex cycles and set suitable bending speed.
3. Press RUN key to launch continuous automatic 90° reciprocating flex test.
4. When the machine auto-stops after reaching preset cycles, release fixtures and take out specimens to observe crack extension, notch growth and surface damage condition.
5. Record crack length data to calculate material flex fatigue resistance index.
