This case study explores the remanufactured 340-20 centerless grinder for bars—a project that turned outdated Cincinnati equipment into a high-performing, precision machine. We’ll explore the challenges, the upgrades implemented and the benefits this remanufacturing brought to the table.
The Challenge: Enhancing Grinding Efficiency
Manufacturers using older grinders like the Cincinnati 340-20 Centerless Grinder face significant hurdles in meeting modern production demands. These outdated machines struggle with issues like inconsistent part quality, frequent downtime and high maintenance costs.
Specifically, the 340-20 machinery was ill-equipped to achieve today’s tight tolerances, causing delays, inefficiencies and escalating operational expenses. Manufacturers required a solution to modernize this equipment to match the needs of fast-paced, high-spec grinding operations.
The Solution: Key Upgrades on the 340-20 Grinder
To update the 340-20 Centerless Grinder, GCH Machinery implemented a number of critical renovations, introducing cutting-edge components and systems that elevated performance.
Dual Comp Slides
- Upper Independent Servo Control: Delivers unmatched precision for consistent results.
- Lower Independent Servo Control: Offers superior tolerance repeatability.
- Time-Saving Advantage: No need for frequent locking/unlocking of slides, reducing downtime and improving reset efficiency.
Regulating Wheel Bearing Conversion
- Eliminated the need for hydraulics, resulting in significantly reduced maintenance requirements.
- Enhanced load distribution through the addition of inboard and outboard support bearings, improving machine stability and performance.
Automatic Grinding Wheel Hood Lifter
- Designed with operator safety in mind, this hood lifter simplifies the handling of heavy grinding wheel guards during wheel changes.
- This operator-friendly addition reduces physical strain, promoting a safer and more ergonomic work environment.
Allen-Bradley Controls
- Cost-efficient and intuitive, Allen-Bradley controls enable seamless setup and swift size adjustments—perfect for achieving precision results on the fly.
- Reliable and robust, these controls enhance overall machine performance in demanding industrial settings.
Additional Features of the Remanufactured Grinder
Beyond these GCH Machinery upgrades, several additional enhancements were integrated to make the 340-20 Centerless Grinder a powerhouse of efficiency and accuracy.
Summary of Additional Upgrades:
- Servo Transmission: Increases roundness and reduces process vibrations for consistently high part quality.
- Standalone Hydraulic Tank: Minimizes heat transfer to the machine for optimized performance.
- Upgraded Electrical Panels: Featuring PLC and CNC controls for precision grinding and seamless operator control.
- Mist Enclosure: Protects operators and maintains environmental cleanliness.
- Lubrication and Pneumatic Systems: Advanced HMI-tied systems ensure timely automatic lubrication and maintenance updates.
These features, combined with GCH Machinery’s commitment to safety and performance, completely transformed the 340-20 grinder into a state-of-the-art machine.
