Introducing Myself
Twenty-four years of machines that work.
I hold a degree in Mechanical CADD and have 24 years of experience in mechanical and CAD design. I have designed machines for many companies and supervised their manufacture: M.S. sheet-coil straightening and sheet-bending machines for rolling mills, EOT cranes with operating cabins for cement plants, and heavy gantry cranes that raise and lower dam gates.
Most of my work is for the stone-processing industry, where I have designed and manufactured many types of machines. Some are simple Indian machines. Others are designed to match machines from leading foreign manufacturers. Each design improves on the last.
- 01
Design from the load up
Capacity, span, lift height, duty cycle and safety factor come first. The girder, wheels, gearbox and motor are sized from them.
- 02
Drawn to be built
Production drawings, part-wise detailing, cutting lists, BOM and costing are prepared so the shop floor can build exactly what was drawn.
- 03
Made for granite and marble
Line polishers, gang saws, multi-cutters and CNC bridge cutters, designed around how a stone factory really works.
- 04
On site until it runs
Help with erection, foundations and production at the customer's plant, until the machine is commissioned.

Core Capabilities
What he brings to a project.
CAD Specialist · Industrial & Technical Consultancy
Industrial machinery design & drafting
End-to-end design and mechanical detailing for heavy industrial equipment: stone line polishing machines (LPM), gang saws, multi-cutters and CNC bridge cutting setups.
Advanced CAD & 3D modelling
High-accuracy 2D shop drawings, 3D parametric component models, part assemblies and plate profile-cutting blueprints for direct CNC fabrication.
Project turnaround & cost optimisation
Engineering specs that cut fabrication errors and material waste, and get commercial plants commissioned sooner.
Architectural layout & structural drafting
Two-storey elevation blueprints, 3-foot gallery plans and compliant layout drawings (for example the Shree Kutumb project), with Vastu-aligned residential planning and cost-effective material specifications.
See the Shree Kutumb house →Key Project Portfolio
- Full technical blueprints for Line Polishing Machines (LPM), including foundation anchoring and drive-shaft positioning
- Fabrication drawings for chrome pipe assemblies, plate profile cutting and multi-cutter machine configurations
- Fabrication-ready nesting layouts and profile-cutting DXF files that cut raw plate scrap by over 12%
- Worked with fabrication teams so real assembly tolerances matched the 3D CAD models
- Technical drawings for heavy machinery foundations, designed for zero tolerance to structural vibration and settling
- Custom 2D & 3D design and mechanical engineering for industrial manufacturing clients, including delivery cycles and project pricing
