LG - High precision grinding for highest requirements applications
LG: high precision grinding machine
The LG external cylindrical grinding machine, equipped with linear motor technology, features direct drive spindles and a natural granite bed for high accuracy and thermal stability for high-precision grinding.
The machine can also combine conventional abrasive grinding with CBN or high-speed diamond grinding by using a B-axis with electrospindle to suit potential customer needs. It is ideal for high volume production and highly flexible batch production runs of parts such as automotive components, ultra-precision hydraulic parts, cutting tools and form grinding e.g. cam grinding.
- Wheel peripheral speed: up to 140 m/s
- Workpiece length: up to 1000 mm
Advantages
- High precision component grinding, such as hydraulic components, automotive parts and cutting tools.
- The machine’s natural granite base and the linear motor driven slides provide the high accuracy and thermal stability required for these highly demanding applications. These specifications also allow the grinding of non-round components.
- 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 140 m/s and covers the range necessary for grinding with conventional abrasive or super abrasives with maximum torque.
- A versatile and flexible machine with the directly driven B axis and the use of multiple wheels.
- Requirements of completely automated manufacturing processes are fulfilled with the incorporation of customised Danobat automatic loading systems, e.g. integrated gantry or robot solutions, guaranteeing minimum loading and unloading time (2-6 sec depending on applications).
- DoGrind+
- Most relevant machining information displayed in a single view.
- A clearer, more comprehensive list of operations showing the main parameters so that they are easier for the user to understand.
- Multiple optional integrated modules; Profile editor, Contour module, Threads module, Forms module, CAD files import.
