WELDON CNC GRINDERS
Handling the most demanding applications
A complete line of 8 versatile CNC Grinder models
All Weldon CNC grinders are specifically configured, tooled and programmed to suit the end user’s most demanding requirements. Our capabilities include not only conventional grinding, but high speed superabrasive grinding, where we lead the industry in precision and productivity standards.
Weldon’s product range offers a viable solution for practically every external or internal cylindrical grinding challenge on parts ranging from .100″ to 16″ in diameter and from a few ounces to 1,000 pounds. Weldon’s unique machine features and vast expertise with superabrasives offers successful solutions for difficult to cut materials such as carbide, ceramic, exotic aerospace alloys, and hard tool steels.
All Weldon CNC grinders can routinely and automatically grind contours, tapers, chamfers, fillets, radii, shoulders, and straight diameters in one setup and one continuous operation. They have the capabilities for OD/ID work in one setup; ID contouring; and nonround grinding… all with excellent results in productivity and quality. All Weldon grinders are tough enough for large production jobs, and their CNC capability allows for extremely fast setup times that can make completion of even the smallest lots profitable.
Prior to shipment, all machines are tested and qualified on the user’s actual production parts. After shipment, a Weldon engineer will travel to the installation site to asist with start-up and provide on-site training for the operator, programmer and maintenance personnel.
When you turn to Weldon for your CNC grinding requirements, you benefit in these important ways:
- increased productivity and efficiency
- improved part quality
- superior grinding process control
- easy operation, requiring less operator skill
- rapid payback on your investment
You have the confidence of knowing that your grinder supplier has been solving the industry’s most demanding CNC grinding problems since the introduction of CNC in the early 1970’s.
Peel Grinding: A Pioneering Process
Weldon’s peel grinding development effort started in 1997 working with the Aerospace industry. We found that the peel grinding process was perfectly suited for grinding complex forms in exotic materials such as inconel that are very tough and tended to “load” the grinding wheel when using conventional abrasives and plunge grind processes. For example; removing up to .030” stock from the diameter of an inconel shaft in a conventional process would require that the cycle be interrupted twice to dress the wheel for every part. Peel grinding with vit-CBN allowed us to grind up to twenty (20) parts without dressing.
Automation for Grinding
In the machine tool industry our automation solutions set the standard for reliability and affordability. When compared to traditional gantries, articulated robotic solutions enable you to…
- Achieve shorter installation time resulting in lower integration costs
- Replace part carousels with pallets for part queuing to reduce overall system costs
- Eliminate some moving components such as rotary actuators to minimize maintenance expenses
- Use one robot to tend multiple machines with multiple operations to lower your capital investment
- Have more valuable floor space available

Grinder Capabilities: A Look at the Phoenix – Weldon’s Large Capacity ID Grinder
Maintaining accuracy over production runs and reducing changeover time are constant pressures for manufacturers. The Phoenix ID Grinder – a heavy-duty CNC grinder that can automatically grind diameters, tapers, chamfers, radii, shoulders and contours in one set-up and one continuous operation using a FANUC CNC control – was engineered specifically to meet the needs of manufacturers.
Equipped with high frequency, liquid cooled electro-spindles for ID grinding, the Phoenix is designed for high-production, heavy-part applications, carbide/ceramic and flex-production appl ...
