ENGINEERED FOR SUCCESS

All Drake Internal thread grinders are designed and built with customer needs in mind. Constructed with premium materials and equipped with Drake software, we give our customers a competitive advantage. Operators control all process parameters through PartSmart™ menu-driven screens, allowing for minimal mechanical adjustments, efficient changeover time, and increased productivity.

STANDARD FEATURES


  • High-Precision Workhead
  • Wheel Helix
  • Closed-loop Precision Feedback
  • Motorized Wheel Spindle
  • Wheel Spindle Drive
  • Diamond Roll Truing
  • Automatic Wheel Balancer

 

PARTSMART™ MENU-DRIVEN SCREENS
Simplifies setup and ensures accuracy. The operator simply enters part-specific values into the control and the software does the rest.

AUTOMATION
Drake offers a variety of automation options unique to your specific application. With Drake automation solutions,
you will deliver consistent, high-quality results.

LINEAR MOTORS
Machine is built with linear
motors and linear roller ways
for maximum acceleration and
contouring.

 

CAST-POLYMER BASE
Machine is built on a cast
polymer base for vibration
damping and thermal stability.
Compact, high-mass base
allows for high accelerations for
minimizing cycle time.

OPTIONAL UPGRADES

Additional upgrades are available to be added to any of the internal thread grinders to ensure the most advanced requirements are met.

SmartForm™: A software and hardware package corrects wheel forms for helical interference on higher helix parts and for off helix grinding.

TouchDress™: TouchDress™ uses Acoustical Emissions Monitoring (AEM) to enable the grinding wheel to “find” the diamond roll at each dress and make certain the entire wheel periphery is trued. AEM of dress process ensures consistent conditioning of CBN and ceramic abrasive wheels, yielding a productive grinding process.

Part Probe: Hardware and software to provide pre-cut probing and stock dividing functions.

Automation: Fanuc Robotics is fully integrated with the CNC control and designed to automatically load parts.

TRAINING

We offer hands-on training at Drake and at customer location to ensure success.

Training includes

  • part feature definition
  • controls operation
  • preventive maintenance for the complete machine
