LT500 automatic circular knife grinder for bevelled circular knives, counter-blades and rotary knife sharpening.
The LT500 is designed for grinding bevelled circular knives up to Ø500 mm. It can also be used for single counter-blades and multiple counter-blade sets, making it a versatile circular knife grinder for workshops working with circular cutting tools and industrial blade sets.
The machine’s programmable automatic work cycle helps deliver consistent sharpening results across repeated grinding jobs, while reducing operator input compared with manual grinding processes.
The LT500 comes standard with a 250 mm tangential grinding wheel, making it well suited to bevelled circular knives and tangential grinding applications. For workshops needing frontal grinding, the machine can also be equipped with an optional 150 mm face grinding wheel.
This flexibility allows the LT500 circular knife grinder to handle a wider range of circular knife and counter-blade sharpening requirements, depending on the blade geometry and required edge finish.
The LT500 is controlled by a Siemens touch screen PLC with user-friendly software and an intuitive operator interface. The programmable automatic working cycle supports consistent, repeatable grinding and helps operators manage sharpening work more efficiently.
Operators can control the grinding process with precision using the electronic handwheel, table speed adjustment and grinding head rotation. This makes the LT500 a strong option where a workshop needs a more automated circular knife grinding machine rather than a purely manual sharpening setup.
The LT500 is suited to workshops that need more than a basic manual circular knife sharpener. With PLC control, programmable automatic cycles, tangential and optional face grinding, and support for bevelled circular knives and counter-blades, it is built for repeatable industrial sharpening work.
For businesses sharpening circular knives regularly, the LT500 offers a strong balance of automation, control and finish quality. It is a practical option for workshops that need to maintain consistency across repeated circular knife grinding jobs.
