Cast Iron Bench Centres
Rugged Alignment Bases for Concentricity, Parallelism & True Rotation Inspection
Enquire NowProduct Overview
SPT Metrology manufactures Cast Iron Bench Centres built to IS 5980 standards for inspecting concentricity, parallelism, and true rotation of shafts and cylindrical components. As a trusted Cast Iron Bench Centre Manufacturer, we build these for workshops and tool rooms where the bench centre needs to handle heavier components and rougher daily handling than a lab-grade granite setup would tolerate, without losing rotational accuracy.
Rigidity That Handles Real Shop-Floor Loads
Cast iron's mass and rigidity make it well suited to bench centres supporting longer shafts and heavier cylindrical parts, where the base needs to resist deflection under the part's own weight, not just hold a static flatness reading. Every SPT bench centre is cast from close-grained iron and machined, then hand-scraped on the base and V-block surfaces to achieve the fine tolerance rotational inspection demands.
Hardened Centres, Stable Rotation
Each unit is fitted with hardened and ground dead centres that keep test components running true under load, essential for inspecting shafts, spindles, mandrels, rotors, and similar rotating parts, where any wobble at the support points reads as measurement error rather than genuine part deviation.
What It's Used to Verify
Cast iron bench centres from SPT are used to check: concentricity of rotating components, parallelism between reference faces, true running of precision shafts, and axial or geometric tolerance deviations during turning, grinding, and machining QC checks: the same core inspection tasks as our granite version, built on a base suited to heavier-duty daily use.
Sizes & Custom Configurations
Available in a range of standard center distances and base sizes, with custom configurations built to match specific machine components or workstation layouts.
Why Manufacturers Choose SPT
As a Cast Iron Bench Centre Supplier trusted across Tamil Nadu and beyond, we hand-finish every base to hold true rotation under real working loads, not just under a calibration certificate in a controlled lab.
