Key benefits of retrofitting:

  • Less costly than a full remanufacture or purchase of a replacement machine
  • Minimizes downtime -- work can be completed on your shop floor
  • Increases machine capability, reliability and accuracy.
  • Extends the life of your machine
  • Eliminates the learning curve for the operator who will still be familiar with the overall functioning of the machine and controls

Mechanical retrofitting

Even the best equipment ages over time. To ensure reliable performance and maximum service out of your grinding machine, modernization of mechanical components is critical. With over 50 years of experience in machine retrofitting, GCH Machinery offers the newest technology on the market. Upgradable mechanical components include motors, gear boxes, infeed units, dressers, slide systems and more.From decades of hands-on experience, the GCH Machinery team will work with you to determine the scope of your retrofit.


Here are just a few of the available upgrades:

Servo-drive transmission

GCH’s servo drive transmission eliminates 98% of all moving parts, eliminates costly downtime and repairs. This patented upgrade replaces mechanical gear transmissions and provides improved part roundness.


Automatic infeed units

GCH’s automatic and economically priced infeed unit eliminates the manual adjustment of old-style infeed units. Benefits include improved size control, nearly maintenance-free performance, and improvement of wheel and diamond life.


Servo infeed system

GCH’s exclusive servo infeed system replaces difficult Cincinnati mechanical hydraulic infeeds. Improved repeatability and elimination of costly set-up time and maintenance are just a few of the benefits.

Automation retrofitting

Manufacturers in every industry are finding ways to do more with fewer financial resources. Grinder automation can be an excellent alternative for companies that need to get more production out of an older machine. Retrofitting an automation load/unload module on your manual machine will decrease part cycle time, improve part quality and reduce waste, leading to lower costs per part and better precision. Further, incorporating automation takes the rate of production out of the operator’s hands, leading to consistent, faster production rates. 


GCH Machinery can retrofit a number of automation options, from the most basic to the most sophisticated:

  • Gantries
  • Rotary tables
  • Loading and unloading stations
  • Pick and place
  • Gripper arms
  • Vibratory feeders
  • Conveyors
  • Robots

Electrical retrofit

Perhaps your grinding machine is still mechanically sound but its antiquated electrical system hinders the machine’s accuracy or ability to perform additional profit-generating tasks. Let GCH propel your grinder’s electrical system into the 21st century. Whether a partial retrofit or a full-blown new electrical system is in order, GCH engineers and technicians are well-versed in all facets of electrical retrofitting, having upgraded more than 500 grinding machines.


GCH offers any of the following new components:

  • Servo drives
  • Electric cabinet
  • Operator pendent
  • Machine wiring
  • Positioning and feedback systems

Controls retrofitting (partial)

Are your machine’s controls past their prime? While complete replacement may be considered, this solution isn’t always necessary, feasible or cost effective. A better solution is a “partial” controls retrofit, which includes replacement of key components of your controls system. GCH Machinery will retrofit a new controller and/or processor to your machine, providing a “second life” to your investment, and boosting your equipment’s capability, accuracy and repeatability. Replacing components or integrating upgrades in your facility saves time and money.


Hydraulics retrofitting

GCH Machinery will replace your hydraulic system with electrical motors to stop messy leaks and eliminate the need to use and discard costly machine oils.

GCH Machinery offers retrofitting services for centerless, ID, OD (cylindrical), surface and double disc grinders.
