Vertical Profile Projector (Optical Comparator)

A Vertical Profile Projector (VPP), also known as an Optical Comparator, is a precision optical measuring instrument used to inspect and measure the dimensions, shape, angles, and profiles of small components by projecting a magnified image onto a screen.

A Universal Testing Machine (UTM) is a mechanical testing device used to determine the mechanical properties of materials by applying controlled tensile (pulling), compressive (pushing), bending, shear, or other loads.

Main components

• Load frame: Supports the entire machine.
• Crosshead: Moves up or down to apply the load.
• Load cell: Measures the applied force.
• Grips/Fixtures: Hold the test specimen securely.
• Extensometer: Measures the specimen's deformation (strain).
• Controller and software: Operate the machine and record test data.

Common tests performed

• Tensile test – Measures tensile strength, yield strength, elongation, and Young's modulus.
• Compression test – Determines compressive strength.
• Flexural (bending) test – Measures bending strength and stiffness.
• Shear test – Evaluates shear strength.
• Peel and adhesion tests – Commonly used for adhesives and bonded materials.

Working principle

1. The specimen is mounted between the grips or compression plates.
2. A controlled load is applied at a constant speed.
3. The load cell measures the applied force while the extensometer measures deformation.
4. The software plots a stress–strain curve and calculates mechanical properties.

Applications

• Material testing laboratories
• Quality control in manufacturing
• Research and development
• Civil, mechanical, aerospace, and automotive engineering
• Testing of metals, polymers, composites, rubber, textiles, wood, and concrete

Advantages

Typical output

A UTM provides:

• Maximum load
• Tensile/compressive strength
• Yield strength
• Young's modulus
• Percentage elongation
• Stress–strain curve

The machine is called "universal" because, with different fixtures and accessories, it can perform a wide variety of mechanical tests on many different materials.

Metallurgical Inverted Microscope

A Metallurgical Inverted Microscope is a specialized optical microscope used to examine the microstructure of metals and other opaque materials. Unlike an upright microscope, the objective lenses are located below the specimen stage, while the illumination is directed upward through the objectives onto the specimen surface. This design is ideal for observing large, heavy, or irregularly shaped samples that cannot be placed on a conventional microscope.

Definition

A Metallurgical Inverted Microscope is an optical instrument designed to study the polished and etched surfaces of opaque materials such as metals, alloys, ceramics, and composites for microstructural analysis, quality control, and failure investigation.

Main Components

• Base: Supports the microscope.
• Objective Lenses: Located below the stage to magnify the specimen.
• Eyepieces (Oculars): Used to view the magnified image.
• Specimen Stage: Holds large or heavy specimens.
• Reflected Light Illuminator: Provides illumination from below through the objectives.
• Coarse and Fine Focus Knobs: Adjust image sharpness.
• Nosepiece: Holds multiple objective lenses.
• Digital Camera (optional): Captures images for analysis and documentation.

Working Principle

1. The polished and etched specimen is placed on the stage.
2. Reflected light is directed onto the specimen surface through the objective lens.
3. The reflected light carries information about the specimen's microstructure.
4. The objective magnifies the image, which is further enlarged by the eyepiece.
5. The observer or digital camera records the microstructural details.

Applications

• Metallurgical laboratories
• Quality control in metal industries
• Failure analysis
• Heat treatment evaluation
• Grain size measurement
• Weld inspection
• Research and development
• Educational institutions

Advantages

Stm make RHT 150 E' Series of Hardness Testing Machines comes with much improved design & look with following major design changes.1) The machine body having a taper front look and a big size dial gaugein the front. The machine is powder coated for better look.The paint shade do not fade and machine looks like new over year.2) The elevating screw of machine is guided in a hardened and groundbush, not allowing movement of elevating screw more than 0.05mmwhen raised to full height. The accuracy is returned for years togetherdue to hardened bush.3) A hardened and ground stepped bush is fixed on top of main screwfor location and rest surface. This guarantees no change in resultsdue to rough handling of test table or test piece. It means a troublefree long life machine accuracy.4) An antifriction linear bearing with almost no clearance is provided fora prefect vertical movement of loading plunger with minimum friction.This enable testing of a small dia. pin or ball up to 3mm dia.5) All machine modes are provided with automatic zero setting dialgauge readout. Hence zero setting at every test is avoided
