Auto Instruments & Engineers Kolhapur, Maharashtra

Features :Very wide testing range from soft metal like lead up to hardest metals like hardened steel.Small indentation to allow testing of precision finished parts.Motorised loading and unloading.Suitable for thin sheet metals since test loads are very small.Built - in projection screw to get accurate results.

Auto Instruments & Engineers Vickers Hardness Tester is a simple & accurate means to produce and measuring the diamond indentation.These testers are suitable for measuring the hardness of precision metallic parts with wide testing range-from soft to hard, and their accurate results are widely acclaimed.These testers strictly conform to IS: 1754 - 1986

Construction :The robust machine frame is designed to accommodate the high precision loading system and an optical projection screen. Specimen is placed on a testing table.The test cycle is fully automatic. The accurate load is applied on a diamond penetrator by means of automatically. The objective is indexed with the test piece and the diamond indentation is projected on the measuring screen. The diagonals of the indentation are measured by means of the micrometer screw of the projection screen

Features :Fully Computerised (PC Based) Vickers Hardness Machine.Direct and accurate measurement of Vickers Handness Number using." State of Art " image processing technology.High accuracy and repeatability of measurement at all loads. Faster measurement yielding to higher productivity.Motorised loading and unloading cycle.Small loads allow testing thin sheet metals.'Wide testing range' : from soft metal such as lead up to medium hardened steels.Small size of indentation makes it a non-destructive testing on finished components.Advanced Window 95 / NT based software.

Latest G U I Features :Online indentation setting and focusing on.PC monitor.User-friendly software with all help file and Window Features.Advance image processing : Algorithms implemented for precise calculation of hardness numbers with various options to cover all ranges of specimen.

Fully Computerised (PC based) Micro Hardness Tester. Direct and accurate measurement of micro hardness number using" State of the art" image processing technology. Wide testing range: From soft metal such as lead up to hardest, like hardened steel. High accuracy and repeatability of measurement at all loads. Small size of indentation makes it a non destructive testing on finised components.Load slection by external knob. Motorised loading and unloading cycle. Small loads allow testing of thin sheet metals. Advanced Window 98 Based Software: Latest GUI features with user friendly software. On line indentation setting and focusing on PC monitor. Advanced Image Processing: Algorithms implemented for precise calculations of hardness numbers with various ootions to cover all ranges of specimens. Batch File Processing: Option for datal storage and reports generation for case depth analysis etc.

Rockwell, Rockwell superficial& Rockwell cum Brinell test consists offorcing an indentor (Diamond or Ball) into the surface of a test piece in two steps i.e. first with preliminary test force and thereafter with additional test force and then measuring depth of indentation after removal of additional test force (Remaining preliminary test force active) for measurement of hardness value.RASNE series machines are suitable for Rockwell, Rockwell superficial& Rockwell cum Brinell tests. These are motorized digital Hardness testers having LCD display for easy hardness measurement. The results are displayed in 0.1 Rockwell unit for more accurate measurement.

OPERATION :

Various parameters of test can be set on front panel by operation of key board and observing LCD display Viz high/low limits, dwell time, auto/manual start, printer selection, scale selection etc. All set data can be verified edited by pressing SCL key one after another.Machine operation is very simple. The normal mode is a bar followed by "SET" indication. Raise elevating screw slowly through bar indication till "SET" position which will show "PRESS START" indication. Now press "START" button. Loading/unloading cycle will be completed and hardness is shown on LCD display with high/Good/Low indication. Lower down elevating screw. Panel will show normal mode for next test. Also when required 'AUTO START' set 'AUTO START' on front panel by operation of key board & observing LCD Display then raise elevating screw slowly through bar indication till "SET" position then it will starts loading/unloading cycle automatically & hardness is shown on LCD Display with High/Good/Low indication.
