Used CNC Grinding Machine: Affordable Solutions

Discover Our Services

Used CNC grinding machines cater to a wide variety of materials, including metal, wood, stone, glass, and plastic. They come in various designs tailored to specific purposes, such as cylindrical grinding, surface grinding, centerless grinding, and even precise jig grinding machines.

At Stenzel, we offer everything from brand-new round grinding machines to used centerless grinding machines, all at competitive prices. For those interested in precision work, we also have a jig grinding machine for sale. Our grinding machines feature varying degrees of automation, with conventional grinding machines being ideal for single-item and small-batch production, and CNC-controlled grinding machines demonstrating efficiency advantages in large-batch production.

In manufacturing processes, grinding typically follows the machining of a workpiece, refining its shape, smoothness, sharpness, or polish and removing coatings. There is no difference in quality between a new and used CNC grinding machine. We ensure accuracy and optimal condition when selling used CNC grinding machines for sale, providing all the necessary technical information.

Grinding Machines

Abrasives:

The finer the abrasive grain, the smoother the machined surface. Common abrasives include corundum, silicon carbide, or diamond-coated papers or textiles, along with abrasive stones made of pressed and fired quartz sand. Liquid abrasives are also used for precise workpieces. Check which abrasive is required for your used CNC grinding machine before use.

Coolant and Suction Devices:

Cooling lubricants prevent damage to the material and the used CNC grinding machine by dissipating heat generated from friction. The coolant is fed into the machining zone via nozzles and recycled, requiring filtration and cooling.

Grinding machines are equipped with extraction or dust removal systems to ensure ground-off particles don't damage the workpiece. Special oil mist separators are used to extract aerosols and steam.

Buying a Used CNC Grinding Machine:

A used CNC grinding machine is more affordable than a new one, but to ensure long-term profitability, it's crucial to verify the machine's condition. Cleanliness is a top priority, as fine-grinding dust particles can accumulate in hard-to-reach parts of the machine if extraction and rinsing are insufficient. Additionally, check the bearings, as they endure significant stress due to spindle speeds.

Our service technicians have extensive knowledge of used CNC grinding machines from a wide range of manufacturers, including used CNC cylindrical grinding machines for sale. They're ready to leverage their experience and trained eyes to inspect your desired machine.

Renting a Pre-owned Grinding Machine

At Stenzel, we specialize in buying and selling both new and used grinding machines. However, please note that we do not provide rental services for these machines.

Important Considerations for Using a CNC Grinding Machine:

When working with a CNC grinding machine, you need to follow several procedures. The grinding process begins with the coarsest grit size and progresses to smaller, finer grit sizes. The higher the grit size, the smoother the surface.

To protect your health, wear safety goggles and a dust mask during the grinding process. Staying safe and adhering to best practices ensure optimal results from your used CNC grinding machine.
