Grinding machines have been known since ancient times. The original manual machines for shaping, sharpening or smoothing are used today as conventional or CNC grinding machines in various industries. Generally, grinding wheels and grinding belts reach higher accuracies than machining with geometrically undefined cutting edges. For this reason, tool grinding machines, circular grinders, surface grinders, bench grinders, etc., are essential for many stages of production for the industry and crafts. At Surplex you will find a great variety of grinding machines and its corresponding accessories such as used grinding wheels, wheel spindles and many more. High quality for the best price!

In the metalworking industry, dimensions need to be precise down to a thousandth of a millimetre. Even a surface that feels smooth to the touch may be far too rough for the intended application. Milling machines and lathes, for instance, can produce outstanding dimensional accuracy, but the final touch can only be applied using an appropriate grinding machine.

This particularly applies to surfaces subject to narrow tolerances: piston tracks in combustion engine cylinders, for example. They need to precisely and securely guide the piston rings within a wide temperature and speed range without jamming, which can only be ensured through use of a metal grinder.

Grinding machines work without tools: all they need is the corresponding abrasive medium, such as types of paper and textiles with an abrasive surface. Grinding stones are also used and consist of a pressed and fired abrasive medium mostly quartz sand. The finer the abrasive medium, the less surface that will be removed per grinding cycle.

And if solid abrasive media are insufficient to achieve the desired dimensions, fluid abrasive agents are another alternative. Wet polishing machines and lapping machines facilitate this type of abrasion.

Polishing and lapping processes are used for achieving the best dimensional accuracy and a consistently smooth surface, which is ideal for galvanising applications, for example. A product can only be galvanised or chrome-plated if it has been polished to a very high sheen.

Round grinding media carriers are used in eccentric and plate grinders. They consist of a circular surface and the media are either moved radially or eccentrically. Radial grinding machines are designed very simply and are affordable.

Grinders with a belt-type abrasive medium carrier are called belt grinding machines. These types of grinder involve a grinding belt being tensioned between a drive roller and one or two tensioning rollers. They are used to remove outer layers from materials consistently and smoothly. Belt grinding machines remove a pre-defined quantity of material per work cycle, which makes it easy to maintain dimensional accuracy by spreading the abrasion process across different work cycles with varying grinding heights. Belt grinding machines are also designed to be simple and are thus easy to maintain.

A metal grinder always consists of cooling lubrication and powerful extraction. The particles removed from the workpiece need to be transported away as quickly as possible since fine metallic dust can quickly lead to heavy wear and tear. This particularly applies to iron-containing dusts, which increase in volume as they corrode and lead to further damage.

Surface grinders are used when an extremely flat surface is needed. They work using a grinding disc that is consistently guided across a workpiece. These machines are key to the tool-building and mould construction industries and can be relied on to achieve the required dimensional accuracy.

Guideway grinding machines, as the name suggests, are used to grind guideways and are deployed wherever very large cutting machines are being manufactured. Mechanical guideways need to be very precise and the guideway grinders on offer today can achieve tolerances of 1/1000 of a millimetre across seven metres of length.

Internal (cylindrical) grinding machines are used to create consistent and accurate internal radii. They work using roll-shaped grinding bodies. The internal grinding machines available today feature computerised numerical control (CNC) and can thus achieve the strictest of tolerances.

Jig grinders feature CN controls and a very small grinding body. They are used to grind away at specific points on a workpiece as required by the respective production process. As such, jig grinders feature a very similar design to CNC mills.

Cylindrical grinders serve to grind profiles, pipes and round steels in a cylindrical manner. Tensioning cylindrical grinding machines use centre tips similar to the tail stocks of lathes. Centreless grinding machines, by contrast, can be used to indefinitely process profiles without any clamping process being required.

Bench grinders are standard grinding tools that are found in every workshop. A bench grinder can be used to sharpen, grind, plane, or deburr a workpiece by hand. They consist of a motor to which one or two grinding discs are attached. They are produced in single- and double-sided variants.

A Roll grinding machines serve to precisely grind press rollers to the desired dimensions. They can be used to grind new, used and freshly turned rollers to achieve the required tolerance. Precision rollers can only be created using a roll grinding machine.

The wide variety of grinders for sale does not make it easy to choose the right device, but there are some general tips that any prospective buyer of a second-hand grinding machine should know. The first consideration is what applications the (used) device should perform a simple bench grinder is incomparable to a complex jig grinder.

A good starting point is to look at the general condition and cleanliness of the machine. Even with comprehensive rinsing and extraction units, grinding machines require a great deal of cleaning daily, thorough cleaning is essential for any frequently used grinder. If the first thing you notice about a second-hand grinding machine is that it is soiled, you should definitely take a very close look at the machine from all aspects.

Unless you buy a metal grinding machine from a trader in used machinery who has taken care of the maintenance and repair tasks, it will be necessary to completely dismantle and clean the equipment. 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.

The weakest points in all used grinding machines are the bearings: the high speed experienced by the grinding spindles, the continual one-sided impact, and grinding heads that frequently lose their shape have a major effect on the bearings. It is therefore important that the bearings are inspected and, if there is the slightest amount of rattling, replaced. Once equipped with new bearings, a used metal grinder can continue operating for thousands of hours to come.

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 purchase machines via our portal where you will regularly find online auctions featuring 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.
