Frequently Asked Questions
Improving your grinding quality starts with upgrading your existing equipment to meet today’s precision manufacturing standards. At GCH Tool Group, we specialize in retrofitting and rebuilding older grinding machines with state-of-the-art components and automation solutions that bring them up to — and often beyond — modern technology standards.
Our engineering team evaluates your current grinding process and recommends specific upgrades, such as:
High-precision spindles and bearings Advanced control systems like CNC retrofits Servo motor and drive conversions Automated infeed systems for tighter tolerances Coolant system upgrades for thermal stability
These enhancements not only improve part quality and repeatability but also reduce downtime, scrap rates, and energy consumption. Whether you’re operating centerless, surface, ID/OD, or double disc grinders, our custom solutions help you achieve better surface finishes, tighter tolerances, and greater process control — all of which are essential to competing in today’s high-demand markets.
One of the fastest ways to improve operational efficiency and minimize costly downtime is having immediate access to the parts you need — when you need them. At GCH Tool Group, we maintain a multimillion-dollar inventory of new and remanufactured grinder parts, making us one of the largest global suppliers of grinding machine components.
Whether you’re experiencing an unexpected machine failure or planning preventive maintenance, our in-stock inventory of over 10,000 parts allows us to support you quickly and efficiently. This includes:
- Spindles, pumps, and motors
- Hydraulic components
- Control systems and PLCs
- Replacement parts for major OEMs such as Cincinnati, Norton, Landis, Bryant, and more
By partnering with GCH Tool Group, you gain access to same-day shipping, expert technical support, and custom part solutions, ensuring minimal production delays and maximum uptime. Our commitment to fast, reliable part availability helps manufacturers across automotive, aerospace, and other high-precision industries maintain continuous operations and improve overall efficiency.
Reducing scrap rates is essential to increasing profitability, improving quality control, and maintaining consistent production output. At GCH Tool Group, we help manufacturers lower their scrap rate by offering fully remanufactured, in-stock component assemblies on an exchange basis — eliminating the delays and inconsistencies that come with worn or damaged parts.
Instead of sending your components out for time-consuming repairs, simply provide the serial number of your grinding machine, and we’ll ship a precision-tested, high-performance replacement assembly the same day. This quick-turn solution drastically reduces downtime and ensures that your machine is operating with components that meet or exceed OEM specifications.
Our core exchange program covers major assemblies such as:
- Workhead and wheelhead units
- Spindle assemblies
- Hydraulic and lubrication systems
- Dressers, slides, and guideways
Once the replacement GCH assembly is installed and your machine is back in operation, return your old unit to us for a core credit, keeping your costs low while restoring peak machine performance. This program helps ensure greater accuracy, reduced variation, and improved part quality, all of which contribute to a lower scrap rate and more consistent manufacturing outcomes.
Getting better support for your grinding equipment isn’t just about repairs — it’s about optimizing your entire operation for efficiency, consistency, and reduced labor costs. At GCH Tool Group, we provide comprehensive automation solutions that empower your team to operate smarter. With the right automation in place, a single operator can run multiple machines simultaneously, boosting productivity without sacrificing quality.
Our in-house team of experienced mechanical and automation engineers works closely with your staff to design and implement custom automation systems that seamlessly integrate into your current grinding environment. We offer a wide range of proven automation technologies, including:
- Robotic part handling systems
- Bowl feeders for continuous, unattended part delivery
- Gantry loaders for precise part placement
- Bar feeders and custom fixturing for high-volume operations
- In-process gauging and closed-loop feedback systems
These solutions help reduce reliance on manual labor, minimize operator fatigue, and ensure consistent cycle times and repeatable results — even in high-throughput production environments. Whether you’re running a single grinder or a full production line, GCH Tool Group offers support, engineering expertise, and advanced automation options to help you scale efficiently and stay competitive.
