Sangha Metrology pioneer bespoke measurement systems online
Sangha Metrology is the global pioneer of 3-Point Bore Gauge design and manufacture. Now operating across three continents, Sangha have expanded their reach by investing in a state of the art design and testing facility in India which acts as the primary design and manufacturing centre. Sangha are well served by in-house distribution facilities in England, Australia, South East Asia and a dedicated distributor in the USA. The facility offers clients from across the globe the opportunity to receive world-class bespoke internal diameter gauging services online which would otherwise require travel to the site which can be costly and inefficient.

Having pioneered the design and manufacture of internal diameter bore gauges, Sangha discovered that the best way to serve the precision measuring needs of industry is to offer bespoke and non-bespoke measuring services online in order to reduce the travel time required for clients. A simple form can be filled in online and an emailed drawing and spec sheet from the client is all that is required to develop measuring applications anywhere in the world. Clients have expressed great satisfaction at the ease of this method. This express service is available to all clients requiring bespoke measuring systems for the measurement of internal diameters up to 200mm (and beyond in some cases.)

How to measure plain bore diameters. ( internal diameters)
There are many methods developed to MEASURE BORES. This can be simple caliper set from a master or micrometer to using advanced calibration equipment housed in temperature controlled laboratory.Method used will depend on the accuracy of measurement required. When inspecting bores by production personal or by inspectors method selected is critical both for speed and accuracy and tolerance stated on the drawing. One other factor that needs to be considered is the skill of the person taking the measurements.

Sangha Metrology has been producing Internal diameter inspection equipment now for 30 years. We have a range of equipment to meet Industries requirement to measure accurately and to satisfy the Auditors needs to have traceable measurements for ISO registered companies.

Internal diameters measurement requirements are many and even the plain internal diameters can be of many different types. These include simple ring gauges to deep holes that are required to be measured accurately.Sangha Metrology has Bore gauges to meet all applications from simple to deep holes and shallow holes. Blind hole measurement to a face or step can be easily measured.

Sangha Metrology type of bore gauges are very useful to aid manufacturing whether components are produced on simple manual lathe or CNC Lathes and VMC milling machines. Semiskilled persons can use these with speed to minimize downtime for production process. Setting up a machine is also simplified for first off part. Reducing setting time and eliminating wastage.

Digital readout for bore gauges are a must these days as readings can be stored and used for SPC. Sangha Bore gauges are ideal for this purpose. Sangha system is also able to link to mobile internet applications through Blue tooth technology.

Sangha Metrology has 30 year history of supplying not only standard plain diameter measuring instruments but has a well established reputation for supplying customer bespoke applications on many different types of special applications.
