Different Types of Grinders

Scheduled Service Plan

Industrial grinding machines are a staple in dozens of industries, used both to produce components and maintain the tools that support manufacturing processes. Grinders use abrasive wheels or drums to remove material and refine the surface finish of products and components. In most cases, grinders are used to maintain the metal tools that are used in the machining and cutting of other materials, such as timber and steel. Choosing the correct grinding machine can have a marked impact on your business, significantly prolonging tool life and allowing equipment operators to keep their machines up and running for longer.

Face Grinder

Among the most flexible grinding solutions available for timber workshops, face grinders can be used to maintain a range of tools, such as planing knives, finger joint cutters, circular saw blades, profile cutters and CNC cutterheads. By combining a circular grinding wheel with highly adjustable tool rests and tables, face grinders can be used to reface almost any cutting surface. When paired with precise adjustability parameters, face grinders can accept a variety of grinding tooling and be used to achieve even the highest quality finishes. Because they are often used to maintain carbide tools, most face grinders are equipped with a built-in coolant system to manage heat and improve the finished result.

Drum Grinder

Rather than using a circular grinding wheel, drum grinders use abrasive cylinders to remove material. Drum grinders are especially useful for removing material on workpieces that are cylindrical or which have a large surface area. In some cases, two drums are combined to form a centreless grinder. Centreless grinders forgo the need for a chuck or other tool holders, instead of using the opposing rotation of the drums to centre the workpiece – usually a cylindrical component – and provide an even finish all the way around.

Knife Grinder

Interchangeable knives power many of the timber industry’s most powerful and commonly used timber processing machines. The quality of the knives that a workshop uses has a major impact on the finished product. Quality knives that are kept in good condition result in better, more refined finishes, adding value to products and reducing the amount of labour each component requires.

Keeping your knives and cutters in good condition becomes much simpler with the help of a dedicated knife grinding machine. Knife grinders are precisely what they sound like – computerised grinders that allow for the precise refinishing and maintenance of knives. Knife grinders come in two main types:

  • Straight knife grinders are designed to sharpen knives with straight blades. Most knife grinding machines come with a high degree of precision and variability, allowing the operator to adjust the grinder to account for the degree of wear on a knife and the finish required.
  • Circular knife grinders are used for sharpening circular knives, most commonly used for cutting, trimming and slicing applications.

Profile Grinder

While most grinders are set up to cut straight faces, many timber workshops use profile knives to quickly and efficiently cut intricate shapes, especially for mouldings. Profile grinders use a familiar circular grinding wheel setup to cut and maintain profile knives. The unusual shapes require a greater level of precision and adjustability to ensure the grinding wheel can reach the cutting surface without damaging the surrounding parts of the knife. Since profile knives are often custom made, having the ability to precisely maintain them can reduce expenses and improve product consistency.

“Stirling Machinery’s Planer Sander replaced the two existing sanders we had onsite. Finishing tabletops, a process that originally took two to three hours across two machines, has now been reduced to a matter of minutes in a one-pass finish. The team took the time to understand my operation, how it is run,and what we were looking for in terms of increased capacity and timber finish, and came back with a tailored solution that ticked all of the boxes.As a furniture maker of 35 years, I have been very impressed by the level of service,support and results Stirling has provided. From adding one machine, we have gained time, quality, space, output and efficiency and I couldn’t be happier.”
