Automatic Notching Machine "Notching Tool A-4/A-4E"
This is a notch processing machine that automatically performs notch cutting on Charpy impact test specimens and Izod impact test specimens. It enables high-precision notch processing with minimal burrs.
● This is a machining machine for notching that performs notching cutting processing on Charpy and Izod impact test specimens based on the notching processing conditions specified in JIS K 7144 and ISO 2819. ● It is possible to set and register processing conditions (such as cutting depth per pass and feed rate) according to the material of the test specimen. ● High-precision notching cutting processing can be achieved in increments of 0.01 mm using a pulse motor. ● In addition to notching cutting processing for impact test specimens, the A-4 type can also cut out test specimens for impact, bending, creep, etc., from JIS K 7139 and ISO 3167 multi-purpose test specimens (A-type dumbbell) (both end slice/side cut). ● The dimensions of the notch cutter tip and the actual notch dimensions of the processed samples are inspected and managed using a contour measurement machine.

Introduction to the Universal Material Testing Machine "Strograph"
The "Strograph" is a versatile testing machine that conducts characteristic evaluation tests for tensile, compression, and bending strength of various materials such as plastic and rubber. It can measure the mechanical properties of test specimens, including "tensile strength, elongation, yield point, endurance limit, stress, bending load, bending strength, and bending modulus." 【What is a Tensile Test?】 The purpose of a tensile test is to understand the characteristics in relation to tensile force. This test applies tension to the sample until it fractures, measuring the mechanical properties such as tensile strength, yield point, and elongation. From these measurements, the fracture state and yield state are calculated and used for material strength calculations. 【What is a Compression Test?】 A compression test involves placing test specimens, such as rectangular prisms, cylinders, or cylindrical shapes, between two parallel plates and applying a load to determine the relationship between stress and strain until failure occurs. 【Specifications of the Strograph】 You can choose from models with a capacity ranging from 500N to 50kN. Additionally, we offer a variety of grips (chucks) depending on the samples being measured. If standard products do not meet your needs, custom solutions are also available, so please feel free to consult with us. We have demo units available at our factory, so if you wish to measure samples, please do not hesitate to contact us.
