Grinder Capabilities: Weldon’s Midas Series OD Grinders
In modern manufacturing, success depends on producing high-quality components quickly, accurately, and consistently. The Weldon Midas Series CNC cylindrical grinders are engineered to meet these demands, delivering exceptional grinding performance for high-production applications while providing the flexibility to handle a wide range of part configurations.
From automotive and aerospace components to industrial shafts and hydraulic systems, the Weldon Midas Series combines advanced CNC technology, robust machine construction, and versatile grinding capabilities to deliver quality—over and over again.
DESIGNED FOR HIGH-PRODUCTION GRINDING
The Weldon Midas Series is built to satisfy demanding production requirements in both between-centers and chucking applications. Its flexible design allows manufacturers to grind a variety of workpiece geometries with minimal setup time, helping reduce downtime and increase throughput.
Available with straight, angular, or turret-style wheelhead configurations, the Midas Series can perform multiple grinding operations in a single setup, including:
- Outside diameter (OD) or internal diameter (ID) grinding
- Shoulder grinding
- Face grinding
- Taper grinding
- Radius grinding
This versatility improves efficiency while maintaining the precision required for today’s tight manufacturing tolerances.
ENGINEERED FOR LONG-TERM RELIABILITY
Grinding carbide, ceramic, and other challenging and advanced materials requires equipment built to withstand harsh operating environments. The Weldon Midas Series features sealed rotary and linear axes that protect critical machine components from airborne contaminants, significantly enhancing machine longevity and reducing maintenance requirements.
At the heart of the machine is Weldon’s innovative Shear Damper® machine base. Utilizing shear tube technology, this design provides exceptional stiffness, vibration control, and thermal stability—critical factors for maintaining grinding accuracy during extended production runs.
ADVANCED CNC CONTROL AND MOTION TECHNOLOGY
The Midas Series is equipped with a FANUC 0i-TF Plus CNC control featuring a color LCD interface and FANUC AC digital servo technology. This powerful control platform provides precise machine motion, process control, and reliability for demanding production environments.
Additional standard features include:
- Cross-roller linear way system with recirculating bearings and precision-ground rails
- Precision-ground, double-nutted ballscrew assembly on the X-axis
- FANUC linear motor drive on the Z-axis
- Low-inertia break-away coupling for X-axis ballscrew protection
- Automatic lubrication system with CNC-monitored fault protection
- Variable-speed wheel drive with dynamic braking
- Heavy-duty live spindle workhead featuring a 6-inch A2 spindle nose and #5 Morse taper center
- Lever-operated, spring-loaded tailstock with #5 Morse taper center
- Full machine enclosure with sliding front and side access doors
Together, these features ensure smooth machine operation, exceptional positioning accuracy, and long-term reliability.
SPECIALIZED GRINDING CAPABILITIES
The Weldon Midas Series is ideally suited for high-speed peel grinding applications utilizing vitrified CBN abrasives. This process enables efficient material removal while maintaining outstanding surface finish quality and dimensional accuracy.
Manufacturers can further expand machine capabilities with:
- Turret Wheelhead Configuration: For complex grinding applications, an optional turret-based wheelhead enables formed-wheel plunge grinding as well as multiple diameter and shoulder grinding operations within a single setup. Multiple spindle combinations with straight OD spindles, angled OD spindle, and ID spindles are available.
- Non-Round Grinding Capability: An optional programmable workhead with rotary scale and speeds up to 950 RPM can be integrated for non-round grinding applications. Combined with the available programmable C-axis package and optional X-axis linear motor, manufacturers can accurately produce complex profiles and specialized geometries.
FLEXIBLE AUTOMATION AND PROCESS CONTROL
To maximize productivity and part consistency, the Midas Series offers a comprehensive range of automation and process monitoring options, including:
- In-process gaging for automatic size control
- Renishaw probe-based automatic lateral locator systems
- Acoustic emissions sensors for grind process monitoring, gap elimination, crash detection, and touch dressing
- Power-operated tailstock with smart cylinder feedback
- Electric rotary dressing systems for superabrasive wheels and extended diamond life
- High-pressure grinding wheel cleaning systems
These technologies help optimize grinding performance, reduce scrap, and improve process repeatability.
CUSTOMIZABLE WORKHOLDING AND COOLANT SOLUTIONS
Every grinding application presents unique requirements. The Midas Series can be configured with a wide variety of workholding systems, including:
- Manual and powered jaw chucks
- Collet chucks
- Magnetic faceplates
