- For machining small to medium-sized components
- Uses CBN, diamond, and conventional abrasives, in combination if needed
- Achieves a maximum peripheral grinding wheel speed of 23600 sfpm (120 m/s)
VERSATILE AND HIGH-SPEED PRODUCTION GRINDING MACHINE
Features like a direct drive spindle and a wheel head driven by a zero backlash torque motor make the LG ideal for high volume and flexible batch production.
Complete machining of your part in just one set-up
The LG can perform different grinding and measuring operations in a single set-up, increasing the productivity of the machine.
External diameters, faces, tapers, non-round shapes, etc. in one clamping.
Enjoy the shortest changeover times
- Auto set up cycle for dressing a new straight grinding wheel
- Automatic wheel changing cycle
- Z axis reference block for wheel touch offset reference to avoid manual setting
- Tailstock quill ranges from 3.15 to 6.70 inches (80 to 170 mm)
We do machining tests on your parts
We offer application engineering services to find the best grinding solution for your production requirements, and to design the most suitable machining process for your part.
One of the most user friendly interfaces in the market
With its DoGrind+ software, you can program the LG’s grinding process intuitively and easily.
You can program the LG right at the CNC control, or on your laptop, without having to stop the machine.
- Direct-drive workhead spindle, grinding wheel spindles and dressing tool spindles
- High precision bearings with lifetime grease lubrication and temperature control
- Suitable for high rotational speed
Natural granite bed
Natural granite is one of the keys for achieving the highest accuracy and the best surface quality.
- Thermally very stable
- Coolant through the bed and grinding area
- Outstanding vibration damping properties
- Environmentally friendly
Swivelling B axis
- High resolution swivelling B axis, infinitely programmable
- Torque motor driven for zero backlash
- High resolution rotary encoder to control angular positioning
- X and Z axis linear motor drives, allowing for highly dynamic axis movements
- Drive function with no mechanical contact, resulting in no wear and low maintenance
- Ultra precision positioning and repeatability
From straight (S) or angular (A) infeed types to a full swivelling wheel head B axis that can hold several configurations to provide the most flexible grinding solutions.
