Loroch GmbH

The specialist for saw blade sharpening

Originally founded in Heidelberg in 1899 as a craft business, Loroch has developed into today's modern, efficient and worldwide operating industrial concern.

We are producing sophisticated machines for the grinding of saw blades and band saws. Our wide range of products contains simple manual machines as well as fully automatic service centers. For this we have a machine available for every operational field.

According to our philosophy "Innovation for the grinding techniques" Loroch is permanently pursuing new developments. Because of this, new machine types resp. -variations are presented at international fairs and are brought into the market. We attach great importance to good contact with our customers. Furthermore good communication with the operators contributes to the development of the sharpening machines.



Product launch of the Solution K 850 - an economically priced, advanced CNC machine with automatic chamfering.


Loroch celebrates 100 years in business.


Loroch launches the TC700, an economically priced digital measuring system for HSS and carbide-tipped circular saws. The 100th KSC710 machine is shipped.


For the first time, Loroch offers the KSC710 with chip-breaker unit. This makes the KSC710 the only machine globally that can sharpen and re-tooth saw blades with fully automatic chamfering and with the ability to grind chip-breaker grooves.


Loroch exhibits a prototype model of a low-cost CNC controlled band saw sharpening machine at the Grindtec fair. In 2007, the CNBS80 machine is launched. In addition to sharpening CV and bi-metal band saw blades, the CNBS80 can also sharpen carbide-tipped band saw blades. Integration into the Vollmer Group. 


Loroch develops complete system solutions by offering grinding wheels and coolants perfectly matched for the operation of Loroch machines.
