We help maintain the precision of CNC machining centers, transfer lines, and dedicated equipment used for engine blocks, transmission housings, and structural parts. Our cost-effective remanufacturing and exchange core programs reduce capital expense while restoring performance, and our multi-location network plus complimentary pickup options minimize logistical delays.
Keep your lines running at the speed the industry requires.
Machine Tool
As a core partner to the machine tool sector itself, NNG Industries specializes in the very components that define machine performance—ballscrews, spindles, linear motion systems, turrets, and workholding. We offer complete repair, remanufacture, sales, and retrofit services for virtually every major brand.
Whether restoring a worn ballscrew to original accuracy, exchanging a high-speed spindle, or performing full machine way work and realignment, our technicians deliver results that meet or exceed OEM standards. With extensive technical libraries, 24/7 emergency support, and a tier-one warranty, we help machine tool builders, rebuilders, and end users keep equipment performing at peak levels.
Medical Manufacturing
Medical device and implant manufacturing requires absolute process control, cleanliness considerations, and micron-level precision. NNG Industries provides spindle repair and exchange, precision ballscrew service, and workholding solutions that support the tight tolerances and surface integrity demanded by orthopedic, dental, and surgical instrument production.
Our remanufacturing processes restore geometric accuracy and vibration characteristics critical for high-quality finishes on biocompatible materials. Fast turnaround, documented inspection reports, and reliable warranties help medical manufacturers maintain validated processes and minimize production interruptions.
Trust NNG to keep the machines that produce life-critical components running with the precision patients depend on.

Energy & Petrochemical
Energy and petrochemical operations rely on robust, high-duty-cycle equipment that must perform in demanding environments. NNG Industries services the precision machine tools and components used to manufacture pumps, valves, compressors, turbines, and process equipment.
We specialize in ballscrew and spindle repair/remanufacture, gear box and powerend work, fluid-end support, and complete machine retrofits that restore accuracy and extend service life under continuous operation. Cost-effective remanufacturing, emergency on-callservice, and multi-location support help energy producers and equipment manufacturers reduce downtime and maintain the reliability required for continuous process industries.
Semiconductor
Semiconductor equipment manufacturing and related precision machining demand ultra-clean, ultra-precise motion systems. NNG Industries delivers spindle and ballscrew repair, linear motion solutions, and workholding services that support the extreme accuracy and low-vibration performance required for wafer handling, packaging, and precision component production.
Our processes restore geometric and dynamic characteristics critical to nanometer-scale work. Fast exchange programs and documented quality processes help semiconductor tool builders and component suppliers maintain the consistency that advanced chip fabrication depends on.
General Manufacturing
Across general manufacturing—job shops, contract manufacturers, and production facilities of every size—NNG Industries is the partner for keeping CNC machines, mills, lathes, and automated cells productive. We provide ballscrew repair and same-day service, spindle exchange and remanufacture, workholding repair/sales, complete machine rebuilds, and automation support.
Our combination of technical depth, competitive pricing versus new OEM parts, 24/7 emergency response, and North American logistics network delivers practical, high-value solutions that reduce total cost of ownership and keep production schedules intact.
Food & Beverage
Food and beverage equipment manufacturing and maintenance demand reliable, durable machinery that performs consistently in hygienic and high-washdown environments. NNG Industries supports the production and upkeep of processing, packaging, and filling equipment by providing complete machine repair, service, retrofit, and related component solutions.
We help restore accuracy and reliability on the production machinery that builds stainless-steel and specialty-alloy components for the food industry. Fast turnaround and durable remanufactured assemblies help minimize downtime in facilities where continuous
Ceramics & Materials Processing
Ceramics, advanced materials, and hard-to-machine composites place extreme demands on spindles, bearings, and linear systems due to abrasiveness and high cutting forces. NNG Industries specializes in restoring and upgrading the precision components that keep grinding, milling, and machining centers productive in these applications.
Spindle repair/exchange, ballscrew remanufacturing, and bearing services are tailored to handle the wear and thermal challenges of ceramics processing. Our solutions extend machine life and maintain the surface finishes and dimensional control required for technical ceramics and engineered materials.
Woodworking & Extrusion
Woodworking machinery and extrusion equipment demand robust linear motion, reliable spindles, and durable workholding under continuous or high-cycle operation. NNG Industries provides ballscrew service, spindle repair, actuator and workholding support, and complete machine repair for the CNC routers, molders, extruders, and related equipment used in these industries.
We focus on restoring smooth, accurate motion and reducing vibration so that surface quality and dimensional consistency remain high. Cost-effective remanufacturing and rapid service options help wood products and extrusion manufacturers maintain throughput and product quality.
