Surface Grinders
Grinding machines for toolmaking etc. – CNC & conventional
Surface grinders for the fine machining of hardened materials
Surface grinding is a process by which a machine tool cuts off tiny chips from materials to produce a smooth surface. The machinery works using grinding wheels covered in abrasive particles of various sizes.

Surface grinders can achieve very high levels of precision within a range of 1/1000 millimetre, which is a significant factor in its popularity in the tool manufacturing industry. Another field for which surface grinding machines can be used is in the finishing of hardened materials. A surface grinder consists of a machine body that supports all the components, except for the coolant applicator. The grinding head is at the rear of the surface grinder and is attached to a stand that allows adjustments to be made. The movable machine table is located to the front and features clamping slots. The machine table can be moved horizontally along two axes. The grinding wheel is fed-in vertically by moving the grinding head with a hand crank ‒ automatic feeding is available in some models. The machine table is also operated via a hand crank, or automatically in the case of a CNC surface grinding machine.

Using a surface grinder
The device performs a movement parallel to the operator on top of high-precision guidance tracks. A magnetic chuck operated electronically or by hand holds the workpiece in place. A parallel vice and special clamping units also feature in the grinding process. If properly dressed, the grinding wheels can also be used to create profiles and certain angles can be achieved by tilting the clamping unit.
History of surface grinding machines
Surface grinding machines have been in use since the first half of the 19th century for industrial production. Back then, workpieces made from hardened materials could not be milled into shape. With the dawn of the computer age, the first NC-controlled surface grinders came onto the market. These have since however been replaced by the CNC surface grinder. Today, CNC surface grinding machines are the gold standard in effective manufacturing. Other devices, such as the rotary surface grinder, hydraulic surface grinding machine and horizontal/vertical surface grinding machine are now also available.
Fields of applications for surface grinders
Surface grinders
Surface grinders can be used in industry to produce and finish guidance tracks. The surface grinder is also indispensable to the tool-building trade. The machining of ejector plates in mould-making and fine-tuning the plates by grinding the ejector heads are also routine tasks for this device. Larger ejector plates are sanded using a pot-grinding machine. The machine’s cutting tools are used to finish the individual sections of the hardened tool and are assisted by the magnetic clamps, or chucks, which feature a stop bar to ensure the workpiece remains parallel. The cutting angle can be adjusted by tilting the magnetic chuck.
Surface grinder manufacturers & buying used surface grinding machines
Nowadays, there are many surface grinder companies which have focussed heavily on manufacturing these industrial machines. These include established brands, such as STANKO, TOS, MININI, WMW, ELB, PERFECT, FAVRETTO, GUILIN and REICHLE & KNÖDLER. Used surface grinders from these manufacturers come highly recommended, provided they are in a suitable condition.
