At Guru Nanak Machine Tools, we manufacture high‑precision lead screws designed for accurate linear motion, smooth operation, and long‑lasting reliability. Our extensive range includes ACME lead screws, multi‑start lead screws, and precision ground screws, engineered to meet the demanding needs of CNC machinery, 3D printers, industrial actuators, and automation systems. Whether you require standard diameters or custom leads, our lead screws ensure minimal backlash, high positional accuracy, and consistent feed rates – helping you achieve superior performance in every application.
With decades of expertise in screw manufacturing, we focus on precision thread grinding and rolling, robust material selection, and seamless integration with your existing motion systems. Our lead screws are built from high‑grade alloy steels, heat‑treated and precision‑finished to deliver exceptional wear resistance, dimensional stability, and load‑carrying capacity – empowering your equipment to run efficiently and reliably under continuous duty cycles.
Why choose Guru Nanak lead screws
Every lead screw we produce undergoes rigorous quality assurance and is backed by our commitment to precision engineering. From off‑the‑shelf standards to fully customised solutions, our lead screws provide the accuracy and durability that machine builders and maintenance engineers trust.
high positional accuracy
Our lead screws are manufactured with precision‑ground threads and tight lead tolerances, ensuring consistent linear positioning and repeatability for critical motion control applications.
low friction & smooth operation
Engineered with optimised thread profiles and superior surface finishes, our lead screws minimise friction and wear, delivering quiet, smooth linear motion with extended service life.
versatile configurations
Available in multiple diameters, leads, starts, and nut configurations (including anti‑backlash and flanged types), our products suit a wide range of actuation and positioning systems.
durability & wear resistance
Made from premium alloy steels with induction or through‑hardening, our lead screws offer exceptional resistance to abrasion, corrosion, and fatigue – even in harsh industrial environments.
Advanced lead screw technology
Our manufacturing processes incorporate state‑of‑the‑art CNC thread grinding, rolling, and whirling technologies to achieve the highest levels of accuracy and surface integrity. From custom end machining to specialised coatings and lubrication grooves, we offer features that enhance efficiency, reduce maintenance, and extend operating life in demanding linear motion systems.
