LG - External grinding machine

The LG cylindrical grinding machine has been developed for high precision component grinding.  It is ideal for high volume production and highly flexible batch production runs of parts such as automotive components, ultraprecision hydraulic parts, cutting tools and form grinding e.g. cam grinding.

The grinding machine’s natural granite base and the linear motor driven slides provide the high accuracy and thermal stability required for these high demanding applications. These specifications also allow the grinding of non-round components.

The use of electric-spindle makes possible the combination of conventional and high speed grinding. This produces a maximum peripheral wheel speed of 140 m/s and covers the range necessary for grinding with conventional abrasive (60 m/s) or super abrasives (up to 140 m/s) with maximum torque.

In addition, the cylindrical high precision grinding machine is versatile and flexible with the directly driven B axis and the use of multiple wheels. Requirements of completely automated manufacturing processes are fulfilled with the incorporation of customized automatic loading systems developed by Danobat, e.g. integrated gantry or robot solutions, guaranteeing minimum loading and unloading time (2-6 s depending on applications).

• Linear motors on both dressers. High-resolution linear scale to control the position of axes.
• Torque motor B-axis.  ±1 μm repeatability on a 650 mm radius.
• Built-in spindles 
• Work spindle, wheel spindles and dressing rotary spindles driven by built-in motors.
• Extensive portfolio of wheelhead options to enable multiple operations to be carried out in a single set up.
• 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.
