Quality control of forgings. Measuring cracks depth with electrical potential 281M Crack Depth Meter

Each stage of forgings manufacturing demands quality control. It is crucial. The main aims of monitoring consist of detecting external and internal defects and evaluating potential risks they bring for the strength properties of finished products.

Test: сhecking the hardness of a drill with 3 mm (0,11 inches) diameter

Hypothesis and the preparation for the experiment: Considering the small weight of the piece the measurements were made with the TKM-459CE hardness tester and additional “H” probe with 1 kg load. It leaves an invisible imprint, which is crucial when there is such a small test piece.

Measuring the hardness of a gear

Gear is the main element of the transmission mechanism. It is a disc with teeth projecting radially. Two wheels form a gearing pair to transmit rotational or translational motion. Metal gears differ in the type and shape of the tooth profile, surface shape, material, and size...

Test: measuring the hardness between the rotor stages after the hardening

Task description: for the first time the manufacturer faced the necessity to make Brinell hardness testing between the second and third stages of the rotor after the hardening. The distance between the stages is 81 mm. The customer's representative did not inform about the hardening depth.

Test: checking the hardness of the welds

Hypothesis and preparation for the experiment: we decided that UCI TKM-459CE Hardness Tester would cope with the task and asked the customer to send us the samples. We received 7 samples with thickness of 3 mm (0,11 inches).

Testing the performance of VID-345 Flaw Detector and 281M Crack Depth Meter at PAO “Gazprom” facilities

The Research and Manufacturing company "Mashproject" sent the VID-345 Flaw Detector and 281M Crack Depth Meter to PAO "Gazprom" company to test them and receive data for its research work.

Test: measuring the hardness of pipelines details material

Customer: a company that produces stainless steel piping parts – flanges, elbows, fasteners, transitions, plugs, tees, and other products of this kind.

Test: testing the cutting blade’s samples

Objective: The client's company specializes in the manufacturing of cutting tools for logging. A need to measure the hardness of cutting blades of the instruments surged. Testing target: cutting blades of the logging tools with the thickness equal to 1,5-2 mm.

Streamlined hardness control: testing parts from 40X steel with TKM-459C UCI Universal hardness tester

Current solution: the plant laboratory is equipped with modern stationary Rockwell hardness testers, which are currently used. There is a peculiar requirement for testing with such equipment, which implies arranging equipment configuration for each tested piece type.

How hard should be the metal of a knife? Using TKM-459CE UCI hardness tester to measure the hardness of a steel blade

There are numerous types of knives – for fishing, hunting, surgery, and garden works, for kitchen, throwing, or box cutting. There are many piercing and cuttin instruments on the market, which manufacturers are offering.

Testing non-standard metals and alloys

The TKM series testers manufactured by the research and production company "Mashproject" are capable of performing tests on a wide range of metals and alloys. However, once in a while, we need to measure the material's hardness, and the tester's memory...

The hardness of metals and alloys. What does it affect? How do you increase the hardness of a given material?

Metal remains the most used and widespread material to this day, despite the abundance of new materials produced using up-to-date technologies. All manufacturing industries keep using different types of metals and alloys.
