At Guru Nanak Machine Tools, we manufacture and supply a comprehensive range of high‑precision spare parts for CNC turning centers, vertical machining centers, and heavy‑duty industrial machinery. Our extensive product portfolio includes chuck gears, bevel gears, helical gears, drive shafts, bushings, sleeves, turret tool holders, tool post components, and custom‑engineered machine tool accessories – all designed to deliver reliable performance, precise fit, and extended service life. Whether you need an exact OEM replacement, a high‑wear component, or a custom‑machined spare for your specific machinery, our parts ensure seamless integration, minimal downtime, and optimal machining accuracy.
With decades of experience in precision engineering and metallurgy, we focus on advanced material selection, state‑of‑the‑art machining, and rigorous quality control. Our spare parts are manufactured from premium alloy steels (EN 353, 4140, 4340, 20MnCr5, and tool steels), with precision‑cut gear teeth, fine‑ground shafts, and robust heat treatment (carburizing, induction hardening, nitriding) to deliver exceptional wear resistance, high torque transmission, and dimensional stability – even under continuous high‑load and high‑speed production cycles.
Why choose Guru Nanak machinery spare parts
Every component we produce undergoes stringent dimensional inspection, gear profile testing, hardness verification, and torque simulation – backed by our unwavering commitment to precision and reliability. From standard chuck gears to complex bespoke shafts and tooling components, our spares provide the performance and durability that maintenance engineers and production managers trust.
High precision & direct interchangeability
Our spare parts are manufactured to exacting geometric tolerances with precision‑ground bores, accurate pitch diameters, and fine‑finished locating surfaces – ensuring drop‑in fitment and seamless interchangeability with OEM components across all major machine tool brands.
Superior material & advanced heat treatment
Utilizing carburizing steels (20MnCr5), chrome‑molybdenum alloys (4140/4340), and through‑hardened tool steels, combined with case‑hardening, induction hardening (HRC 55‑62), and sub‑zero treatment to ensure maximum wear resistance, contact fatigue strength, and core toughness.
Versatile range of spare components
We supply a one‑stop solution for all machine tool spares – including chuck gears (spur, helical, bevel), spline shafts, actuator pins, hydraulic/pneumatic seals, turret indexing parts, tool holder wedges, and custom wear‑plates – covering your entire mechanical and workholding ecosystem.
Cost‑effective & reduced downtime
High‑quality aftermarket and custom spares at competitive pricing, with rapid turnaround times. Extended wear life and reliable operation mean fewer machine breakdowns, lower maintenance costs, and sustained productivity for your workshop or production line.
Advanced spare parts manufacturing technology
Our manufacturing processes integrate precision CNC turning, gear hobbing & shaping, profile grinding, broaching, and induction heat treatment to achieve the highest levels of metallurgical integrity and geometric accuracy. We also offer reverse engineering services for obsolete or non‑stocked components, ensuring your older machinery continues to operate at peak efficiency with minimal lead times.

Frequently asked questions
We offer a comprehensive range including chuck gears (spur, helical, bevel), drive shafts, spline shafts, sleeves, bushings, turret tool holders, tool post components, indexing pins, hydraulic/pneumatic actuator parts, wear plates, and custom fasteners. We also manufacture complete gearbox assemblies and custom workholding fixtures.
Absolutely. We specialize in reverse engineering of worn or obsolete components. Using advanced measurement techniques (CMM, 3D scanning) and metallurgical analysis, we replicate or even improve upon the original design, ensuring perfect fitment and upgraded performance for your legacy machinery.
We use premium carburizing steels (20MnCr5, 17CrNiMo6), chrome‑molybdenum alloys (AISI 4140, 4340), and high‑speed tool steels for extreme wear applications. Components are case‑hardened, induction hardened, or nitrided to achieve optimal surface hardness (HRC 55‑62) with a tough, shock‑resistant core.
Our quality assurance process includes full CNC machining verification, gear tooth profile inspection (on gear measuring machines), coordinate measuring machine (CMM) inspection, hardness testing (Rockwell/Vickers), and final assembly simulation. Each batch is traceable and accompanied by comprehensive inspection reports.
Yes. Our engineering team offers comprehensive support – from part identification and material recommendation to fitment verification, torque specifications, and maintenance guidance. We help you select the right spare to maximize uptime and ensure your machinery operates at its highest efficiency.
