Rockwell Hardness Testing Machine - Mech.CS.RAS

Features

Mechatronic Control System Hardness Testers Models SE RAS, SE RASM, SE RAB-1, SE RAB-250, SE TWIN are manually operated. All these models are suitable for testing hardness of metals & alloys of all kinds hard or soft, whether flat, round or irregular in shape. These testers are simple in design & easy to operate, yet sensitive & accurate. Various models from the wide range are suitable for Engg. Colleges, laboratories, toolroom, inspection departments, factories etc. These testers strictly conform to IS: 3804-1988, BS: 891 parts 1&2, ASTM:E18 for Rockwell Test, IS: 2281-1983, BS: 240, ASTM:E10 for rockwell Test & IS: 5073-1988, ASTM:E18 for Rockwell Superficial Test.

MODEL : Mech.CS.RAS : Automatic load selection with automatic zero setting dial gauge. Manual Operation.

MODEL : Mech.CS.RASM : Similar to 'Mech.CS.RAS1 but motorised model. Semiautomatic operation for production testing. Drive motor single phase 230V 50 cycles.

ROCKWELL/rockwell COMBINED SYSTEM MODEL

Mech.CS. RAB-1 : Automatic load selection with automatic zero setting dial gauge. Facility for rockwell Tests with 187.5 kgf. load with 2.5 mm ball indentor, additional load 250 kgf. with 5 mm ball Indentor for testing hardness of non- ferrous metals. Manual Operation.

MODEL : Mech.CS. RAB-250 : Similar to 'Mech.CS.RAB-11 but bigger capacity Diamond Holder is guided in a set of two bail cage, which enables testing of small pins having dia. less than 6 mm (upto 3mni dia)

ROCKWELL/ROCKWELL SUPERFICIAL COMBINED SYSTEM

MODEL : Mech.CS.TWIN : Manual load selection with automatic zero setting dial gauge. Manual Operation. Diamond Holder is guided in a set of two ball cage, which enables testing of small pins having dia. less than 6 mm. (upto 3 mm dia.)

 

SERIES RASN:

Rockwell & Rockwell superficial tests consists of forcing 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 & the measuring depth of indentation after removal of additional test force (Remaining preliminary test force active) for measurement or hardness value. OPERATION : For Rockwell & Rockwell Superficial

OPERATION : For Rockwell & Rockwell Superficial Test :

In case of 'RASN' series machines for Rockwell or Rockwell Superficial Test a preliminary test force in first applied & then indicator is automatically set for zero. Quickly thereafter & additional test force is applied without removing the preliminary test force. When the penetration is stabilized, the additional test force is removed & the hardness number is shown directly on the indicator.

For rockwell Test

The operation is exactly same as above. However, the diameter of impression is measured out side of machine by rockwell microscope. rockwell Hardness number is found out by referring corresponding hardness tables showing hardness number against di. of indentation for specified ball diameter and test force.
