Types of grinding machines and areas of application

Workpiece grinding serves to smooth surfaces and remove coatings. The types of grinders to be used depends on the specific area of application. Grinding wheels and abrasives can also be deployed depending on the material and the hardness of the workpieces. The working material can either be metal, natural stone, concrete, wood, plastic or glass, depending on the intended purpose. A wide range of grinding machines with specific functions are used in industrial and artisanal production.

  • Smoothing surfaces and removing coatings
  • Different grinders for specialist tasks
  • The range encompasses hand-held machines through to large-scale industrial equipment
check1 Quality check2 Great offers check3 Personalised

The following aspects can be used to classify the various grinders for sale: a) What type of surfaces are to be produced? b) Where are the surfaces located?, c) How is the movement to be performed? d) How is the workpiece inserted? e) How large is the item requiring machining?

Cylindrical grinding machines can be used to grind out cavities or process cylindrical workpieces and are available in vertical and horizontal versions. These, in turn, can be separated into external and internal grinding machines. Abrasive cut-off machines serve to cut pipes and rods to length. A thin cutting disc is used to cut the material until the workpiece in question has become separated. For large surfaces, a belt grinding machine is used. Profile grinding machines are used to grind down profiled wooden workpieces, such as spline shafts and gear wheels. Multi-spindle machines enable the manufacture of optical lenses and spectacles. Stone grinding machines, as the name suggests, are used to process natural stone. Tool grinding machines serve to sharpen knife blades and tools used for drilling, milling and chiselling.

Grinding machine in operation

From the grindstone to industrial grinders

Grindstones were originally used for grinding and polishing, or a steel block was moved back and forth on the workpiece using loose abrasives. In the 19th century, steam-operated grinders came onto the scene. Nowadays, grinding machines are generally electrically or pneumatically operated. Hand-held devices, such as orbital-, angle- or belt grinders are used in the craft and construction trades. Large-scale industrial machinery features measurement controls, which regularly check the grinding process and make adjustments where needed. Today, a wide range of CNC grinders are used, especially in industrial applications, which are considered to be “universal” grinders. CNC grinding is the ideal way of having a variety of processing tasks performed automatically, which simply need to be programmed into the machine a single time. Once completed, all that is needed are qualified staff who can monitor the CNC grinder as it performs its tasks independently. This reduces the number of personnel required considerably.

Grinding techniques – from fine to course

Grinding is a machining process. Material is removed from the workpiece by means of numerous bonded abrasive grains and a range of grinding processes can be used depending on the respective field of application.

Vibratory grinding serves to smooth surfaces and round off edges. When it comes to fine processing, the next processes to be used are surface grinding, cylindrical grinding, creep-feed grinding, coordinated grinding and profile grinding. When used for commercial purposes, German law stipulates that grinding machines must undergo annual safety inspections. The German accident prevention guidelines (UVV) also prescribe the used of protective goggles.

Closeup on a used grinding machine

Buying used grinding machines

Grinding machines are ideal for the finishing of metallic surfaces. These are metal grinding machines without a defined tool which operate using consumables, such as brushes, belts or plates. A range of fine surface structures can be produced with a grinder, depending on the abrasive material chosen.

Used grinding machines often exhibit a high level of soiling, which is due to metallic dust (at various levels of fineness) being very prone to coating the entire grinder. This can be very harmful to the mechanics and electronics. The first rule of buying a second-hand grinding machine is thus to only focus on high-quality brands. Only by purchasing an industrial-quality grinder can you be sure that all the components are suitably encapsulated and of high quality.

Unless you buy a metal grinding machine from a trader in used machinery, it will be necessary to completely dismantle and clean the equipment. After thorough cleaning and replacing worn components, a second-hand grinder can be safely put back into operation. If those intending to repair/maintain a used metal-grinding machine are lacking in qualifications to do so, a specialist service provider should be commissioned. Second-hand machinery dealers are an ideal way of purchasing a machine for grinding metal. There will be a large range of grinding machines, which will generally already be in an operational condition. This will save a great deal of aggravation and unnecessary work.

Grinding machine manufacturers

A variety of grinding machine manufacturers have built a good reputation for their used machinery. These include ABA, BLOHM, DECKEL, ELB, FLOTT, GÖCKEL, GREIF, JUNG as well as KARSTENS, KELLENBERGER, REMA and VOLLMER. Grinding machines made by INDUMASCH and FORTUNA are also highly recommended. The second-hand grinders for sale range from small hand-held devices suitable for DIY enthusiasts, through to large CNC grinders featuring modern control technology.

Those looking to buy a used grinding machine will find everything they need at Surplex. We regularly have second-hand grinders for sale. You can also sell your machines via our portal. Our online auctions feature a wide range of grinding machine types for a variety of needs and at attractive prices. The metal grinders for sale are generally in a good to very good condition.
