Amongst the services offered extensively by this laboratory are the following:

Calibration Services

Calibration of Reference Masters

Calibration of Reference Masters includes the calibration of Grade ‘K’ Gauge Blocks, Glass Hemisphere, Flick Standard, Master Cylinder, Optical Flat, Step Gauge, Roughness Masters, Master Sphere etc

Calibration of Gauges / Instruments:

Calibration of gauges includes setting Ring Gauges, Dial Gauges, Plug gauge, etc. and instruments include Verniers, Micrometers, Electronic Levels, etc.

Calibration of Measuring Equipment:

Calibration of Measuring Instrument at permanent facility as well as at site includes calibration of Coordinate Measuring Machine, Profile Projector, Universal Length Measuring Machine / Metroscope, Universal Measuring Microscope, Length Measuring Machine, Gear Testing Machine, Gauge Block Comparator, etc.

Inspection Services

The laboratory caters to precision measurement requirements of linear and angular dimensions, form, position, gear parameters and surface texture with traceability to national/international standards. Laboratory also takes up the on-site inspection of large parts using Portable Arm CMM and Laser Tracker system.

Laser Measurement Services

CMTI has been calibrating machine tools from the past three decades. We offer on-site calibration of conventional as well as CNC machinery and measuring equipment. Services include alignment of large machines like Roll Grinding Machines, Plano Millers and Floor type Boring Machines and Structures like Rails, Guide Tracks, etc. Our calibration and measurements are traceable to national and international standards. The services are accredited by NABL for on-site calibration of Machine Tools, CMMs and other measuring machines. Calibration can be carried out as per ISO, NMTBA, VDI-DGQ, JIS & CMMA standards

Dynamic Measurements and Analysis Using Laser Measurement System

Dynamic measurement and analysis is a solution for testing precision machine tools and measuring machines. The Laser laboratory is equipped with Laser Measurement Systems having higher data capture speeds (up to 5000 Hz), which are used for dynamic measurements like velocity and acceleration of slides, which reveal drive errors and stick slip motion. These systems can also be used for monitoring various machines elements for their performance.

Laser Measurement System for Alignment

The Laser Laboratory also offers services in the activity of Alignment using Laser Measurement/ Alignment System. Alignment of the machine prior to calibration is necessary before starting the calibration exercise. The services include alignment of guide ways, guide rails, bores, guide tracks, etc. CMTI has developed the expertise to monitor various parameters during and after levelling and alignment exercise. The laboratory possesses Laser Measuring Systems, Laser Alignment System, Electronic Levels, Auto Collimators, Rotary Calibrator, Alignment Telescope, etc. to assist in the above work.

Calibration of Laser Measuring System

The Laser Laboratory maintains a Reference Laser Measurement System with traceability to International Standards as a Master. Using this system, other Laser Measurement Systems are calibrated by comparison. The calibration covers the overall accuracy of the system along with accuracies of Laser head and Sensors.

Ball Bar System

Ball Bar System with its software is used to measure geometrical errors present in the CNC machines and detect inaccuracies induced by its controller and servo drive systems. It can measure the inaccuracies like reversal error, straight-ness of slides movement, relative squareness of axes, lateral play in the axis, positioning accuracy, reversal spike, servo system lag and lead error, etc.

CMTI’s Customer Profile

Presently over 100 machines are calibrated annually at sites and services spread all over India. The customer profile is very vast and includes machine tool manufacturers, suppliers and user industries including automobile and earth moving machine manufacturing industry, aircraft manufacturers, paper industry and electronic product manufacturers. With a team of calibration experts and support of state of the art instruments, CMTI can offer these services to overseas clients also.
