AFFRI Automatic Hardness Tester MATRIX

Details

AUTOMATIC HARDNESS TESTS ON CRANKSHAFTS AND CAMSHAFTS IN COMPLIANCE WITH ISO 6508 E ASTM E18/E10/E103 STANDARDS
Rockwell - Superficial Rockwell - Brinell / Test loads from 1 to 250 kgf (9,807 to 2452 N)

With MATRIX tester you can perform tests directly in the production department, during the manufacturing process, where the staff can be informed
on test results in real time. Thanks to continuous and fast checking the output qualitative level will be increased.
Due to the high performances and advantages of this hardness tester, the cost of the entire instrument permits a very quick amortisation.

CARACTERISTICS

• Automatic hardness tester suitable for testing camshafts and crankshafts for cars and trucks.
• The load precision is controlled via closed loop load cells at 1000Hz
• Movements on 3 independent axis and the specimen has a 360° flipping rotation.
• It allows perfect positioning at any point.
• The tester head moves on recirculating ball slides to grant light, accurate and fluid movements.
• The moving system of MATRIX allows for fast and easy positioning on different testing points of crankshaft in supporting diameters, on connecting
rods and camshafts.
• Step-by-step computer assistance. It shows to the operator where to perform the test and notices when the right spot is reached, it notices
errors and mistakes forcing the operator to check.
• The program saves every result associated to a specific specimen position and generates dynamic reports for each piece cycle with statistics.
• MATRIX assistive technology presents a user with a sequence of dialog boxes that lead the user through a series of well-defined steps.


FAST & EASY POSITIONING This hardness tester moves on 3 independent axis and the specimen has a 360° flipping rotation. It allows perfect positioning at any point. The tester head moves on recirculating ball slides to grant light, accurate and fluid movements.		LOAD CELL & CLOSED LOOP TECHNOLOGY Load forces are applied through load cells and electronically controlled in “Closed Loop” (Pat. AFFRI) with a frequency of 1 kHz. Each load force is automatically programmed and controlled assuring perfect linearity in every range eliminating the problems associated with traditional dead weight system testers. Results are not affected by any structural deflection, misalignment or external vibration.

ONE BUTTON MEASUREMENTS Just push the start button and the head moves down performing the hardness test cycle in automatic succession without breaching a phase. The entire test cycle is complete and the result immediately appears on the large display. Fully motorized and automatic, the test is not affected by operator influences and can easily be used by operators of every level.		MOTORIZED INDENTER STROKE Motorized and stand-alone extra 50mm/2” stroke which works separately from the total head stroke. During the test, the indenter moves for the whole vertical stroke generating a constant pressure when the specimen is clamped. When testing unstable samples or deflective parts, the measuring head follows the sample without losing contact.

CLAMPING SYSTEM Secure contact with the specimen is always maintained, even in the unlikely event of any specimen movement during the operation cycle. The clamping system assures perfect stability of any test piece throughout the test cycle, even if the specimen is oiled, rusty or dirty. It does not require elevating screws.		AUTO CENTERING The location of the precise testing point through centering is carried out automatically by moving the head supporting carriage which centres itself in a precise and reliable way thanks the exclusive particular shape of the head anvil.
		STEP-BY-STEP COMPUTER ASSISTANCE This unique feature of MATRIX assists the opeator step-by-step during the testing procedure. It shows to the operator where to perform the test and notice when the right spot is reached, it notice errors and mistakes forcing the operator to check. The program save every result associated to a specific specimen position and generates dynamic reports for each piece cycle with statistics.
