When purchasing a cylindrical external/internal grinder, it's essential to consider several key factors. Firstly, the machine's grinding diameter and length should match the size of the parts you intend to grind. Precision and accuracy are paramount, as tight tolerances result in consistent, high-quality output. The grinder's versatility, meaning its ability to handle different shapes, sizes, and materials, is another crucial factor. Consider the machine's speed and efficiency, but ensure these don't compromise accuracy or surface quality. Durability and longevity denote the machine's ability to withstand intensive use. User-friendliness, defined by intuitive controls, simplifies operation and maintenance. Always examine the after-sales service, support, and total cost of ownership, including maintenance and operational costs. With these considerations in mind, you can make an informed investment that meets your operational needs.

Main characteristics to look at

Here are the main factors to take into account:

  • Grinding Diameter and Length: The size of the parts you intend to grind determines the grinding diameter and length capacity of the machine you need. Larger parts require machines with greater capacity.
  • Precision and Accuracy: The precision and accuracy of the machine are crucial. Look for machines that can maintain tight tolerances, even over large production runs. This results in consistent, high-quality output and reduced waste.
  • Versatility: The grinder should be capable of handling different types of grinding processes - external and internal, as well as various shapes and sizes of workpieces. It should also be capable of handling different materials.
  • Speed and Efficiency: Check the machine's speed and efficiency. A grinder with higher RPMs and feed rates can speed up production, but this should not come at the expense of accuracy and surface finish quality.
  • Durability and Longevity: The machine should be robust and durable, capable of withstanding intensive use over a long period. This includes the quality of the machine's components and construction materials.
  • Ease of Use: The machine should be user-friendly, with intuitive controls and interfaces. This reduces the learning curve and makes operation and maintenance more manageable.
  • Service and Support: Consider the after-sales service and support provided by the seller. This includes availability of spare parts, technical support, and maintenance services.
  • Cost: Lastly, the cost of the machine should be within your budget. Consider not just the upfront cost but also the total cost of ownership, which includes ongoing maintenance and operational costs.

What budget to count with 

The cost of a cylindrical external/internal grinder can vary widely depending on several factors such as the machine's size, capabilities, age, brand, condition (new or used), and the seller's location.

On the lower end, used smaller-scale machines or older models could be found for several thousand euros. Mid-range machines, typically used but in good condition with a decent set of features, might be in the tens of thousands of euros range.

For new, state-of-the-art machines from well-known brands, prices could go up to several hundred thousand euros, especially for machines designed for large-scale industrial use with advanced features such as CNC controls, high precision, or specialized grinding capabilities.

However, please note that these are rough estimates and actual prices may vary. I would recommend reaching out to equipment suppliers or checking platforms like Exapro for the most up-to-date and specific pricing information.

Keep in mind that in addition to the initial purchase price, other costs should be considered, such as shipping, installation, maintenance, and operation costs. Always ensure that the machine meets your specific requirements and budget considerations.

For a used machine, you should count between 10 000€ and 78 000€ for quite regular models. You can always use our pricing tool Valorexo to pinpoint a fair market price.

Please make sure you agree on all the details with the seller or ask your Exapro Agent for support.
