LGHigh speed & universal precision grinding machine

External cylindrical grinding

LG OD grinding machine is equipped with linear motors technology with the aim of being the perfect machine for high precision grinding, it has direct driven slides and natural granite bed, enabling high accuracy and thermal stability.

OPTIMISED CYCLE TIME. High speeds 23620 Sfpm (120 m/s) o 27559.1 Sfpm (140 m/s) for applications with CBN wheels
Extensive portfolio of wheelhead options to enable multiple operations to be carried out in a single set up
Thanks to Danobat’s B-axis design with integrated, high resolution rotary encoder, repeatability of +/-0.005 arc sec (+/-1 μm) can be achieved by measuring at a radius of 25.6 inches (650 mm) from the center of the B- axis

Using the "B" axis the machine can combine conventional abrasive and high-speed grinding.

Ideal machine for high mix, small batch sizes or high volume production runs encountered in the automotive, aircraft, hydraulics, gear manufacturing, cutting tools, mold & die and various other industries, regardless of company size.

Advantages

Built in house spindles.

Modular designs for best application adaptability.

Availability.

Critical components built in-house, such as, workhead, B-axis, wheel spindles and MUCH MORE!
Exchange program. Premium, service at a minimum cost, without third-party intervention

Linear motors.

X and Z slides driven by linear motors. Extremely high positioning and repeatability.

Customisable technology. Such as moving tailstock, counter spindle, integration of measuring systems, CNC steady rest, W-axis, Automatic taper adjustment among others.
DoGrind+.

The user is more efficient, working faster and better. The execution time of tasks is reduced by 40%
Faster programming, with the option of displaying only the necessary parameters., among other

Go Fast! The use of a water-cooled electrospindle makes possible the combination of conventional and high-speed grinding. This produces a maximum peripheral wheel speed of 27560 sfpm and covers the range necessary for grinding with conventional abrasive or super abrasives with maximum torque.
AUTOMATED SOLUTIONS. Such as integrated gantry or robot, external gantry solutions as well as turnkey solutions to meet specific customer requirements.
