Lead Programmer – Mill-Turn (DN Solutions SMX2100ST) Werywin Defence Private Limited | Aligarh, Uttar Pradesh | Full-time, On-site About Werywin Defence Werywin Defence is a licensed Indian defence manufacturer in the Land Systems category, building small arms and precision components under the Make in India and Atmanirbhar Bharat . Backed by a 40+ year family legacy in licensed firearms and partnerships with leading international names in the industry, we run a modern CNC precision facility in Aligarh producing high-tolerance defence components on multi-axis machining centres and mill-turn equipment. The Role We are looking for a Lead Programmer to own programming, prove-out and optimisation on our DN Solutions SMX2100ST multi-tasking turning centre. You will turn complex defence part drawings into reliable, efficient, first-time-right processes that combine turning, B-axis milling, sub-spindle transfer and lower turret work in a single setup. You will also build and maintain the Vericut digital twin of the machine so every program is simulated and verified before it touches metal. This is a hands-on technical leadership role: you will program, stand at the machine during prove-out, and set the mill-turn programming standards for the shop.

Key Responsibilities
Mill-Turn Programming
• Develop CNC programs for the DN Solutions SMX2100ST covering main and sub-spindle turning, B-axis milling, simultaneous multi-axis work, lower turret operations, part transfer and cut-off
• Plan complete “done-in-one” processes for complex components such as barrels, bolts, receivers, pins, housings and other firearm and defence parts
• Optimise operation sequencing, spindle synchronization and turret balancing to reduce cycle time without compromising accuracy or surface finish
• Select tooling, holders, cutting parameters and workholding for steels, stainless steels, alloy steels, titanium and aluminium
• Work with post-processors: validate output,



identify issues and coordinate corrections with the CAM/post vendor Vericut Simulation and Verification
• Build, configure and maintain the Vericut machine model of the SMX2100ST, including kinematics, controller configuration, tool libraries, fixtures and stock models
• Simulate and verify every G-code program before release to check collisions, near-misses, over-travel, gouges and material removal
• Compare simulated stock against the CAD model to catch errors before machining
• Use Vericut Force to optimise feed rates based on cutting conditions, improving cycle time and tool life
• Maintain a library of verified programs, setups and tool assemblies Prove-Out and Production Support
• Lead first-article prove-out at the machine with operators and setters
• Resolve chatter, deflection, dimensional and surface-finish issues in real time
• Work with Quality on first-article inspection, CMM results and corrective actions
• Release validated programs, setup sheets, tool lists and process documentation to production Leadership and Standards
• Set mill-turn programming standards, templates and best practices for the team
• Mentor junior programmers and operators on multi-tasking machine programming and safe operation
• Review drawings and give design-for-manufacturability feedback to engineering
• Contribute to quoting, cycle-time estimation and capacity planning for new parts
• Maintain program version control and documentation in line with ISO9001, As9100, defence quality and confidentiality requirements Qualifications and Experience
• B.
Tech / B.
E. in Mechanical,



Production or Manufacturing Engineering preferred; Diploma holders with exceptional mill-turn experience will be considered
• 8–10 years of hands-on CNC programming experience, with significant experience on complex mill-turn / multi-tasking machines (twin-spindle, B-axis, lower turret)
• Direct experience on DN Solutions (Doosan) SMX-series machines is strongly preferred; experience on comparable machines such as Mazak Integrex, DMG MORI NTX, Okuma Multus or Nakamura-Tome will also be considered
• Strong working knowledge of Vericut, including machine and control setup, simulation and verification; experience with Vericut Force optimisation is a strong advantage
• Proficiency in at least one mill-turn capable CAM system such as Solidcam (Preferred), or Mastercam Mill-Turn.
• Strong G-code and M-code knowledge on FANUC and/or Siemens Sinumerik controls, including manual editing, macros and synchronisation codes
• Ability to read complex engineering drawings and apply GD&T; confidently
• Solid understanding of cutting tools, metallurgy, workholding and machining tight-tolerance parts Preferred Skills
• Experience in high-precision, high-accountability manufacturing
• Familiarity with CMM reports, first-article inspection and process capability (Cpk)
• Exposure to PDM/ERP environments (e.g. Autodesk Vault, SAP Business One)
• Experience building post-processors or working closely with post developers

What We Offer
• A key role on a newly established, modern machine shop with premium equipment
• The chance to shape mill-turn programming standards from the ground up
• Work on complex, meaningful defence and precision firearms components
• Exposure to international partnerships and export-oriented manufacturing
• Competitive compensation aligned with experience Additional Information
