YUYANG

DALIAN YUYANG INTELLIGENT (China) is the largest Chinese manufacturer of equipment and technologies in the field of automatic grinding of castings from cast iron, steel and light alloys using automated grinding equipment (CNC grinding machines/lines or robotic grinding cells/special purpose machines).

Powerful and flexible CNC machines from DALIAN YUYANG INTELLIGENT are the best choice for processing castings where high grinding rates are required, automatic cutting of the casting feeding system, with the ability to perform pre-machining.

DALIAN YUYANG INTELLIGENT propose flexible, efficient and safe solutions for foundries

List of CNC grinding machines from DALIAN YUYANG INTELLIGENT

(*) part + fixture (device for installing the part into the machine)

In addition to the standard line of machines, DALIAN YUYANG INTELLIGENT produces special equipment according to individual customer requirements, for example:

• Passing grinding centers

• Fully automated grinding shops

Main features of the equipment

• Fast part loading

The castings loading and unloading is performed by means of a two-position pallet, with outside manual loading area controlled by safety barriers that stop the pallet changer rotation if interrupted accidentally by the worker. The pallet changer system automatically loads the raw part and download the ground part.

When the part is inside the machine a pneumatic tailstock clamps it on the fixture assuring stable grinding operation.

• Laser measuring device

After been loaded inside the working area the part is automatically checked by the laser measurement system to verify its real location on the jig and its dimensional deviations compared to the masterpiece. The grinding program is then automatically adjusted according to the laser readings granting a consistent finishing quality for all the pieces produced.

• 5 axis grinding

After the part is checked by the laser the grinding cycle starts. The electro spindle carrying the grinding tools is mounted on a CNC controlled rotary axis for optimal positioning of the tool in the space. The standard electro spindle carries two tools (one large wheel and a small cutter). Totally the machine has 5 CNC controlled axes granting maximum flexibility and best automatic finishing of the grinding process.

• Tool Magazine

Optionally the machine can be equipped with automatic tool changer and a tool magazine (up to 20 tools).

In this way, for each part to be ground, dedicated tools can be used in order to maximize the automatic finishing level, with tool change done automatically in just few seconds.

With this unique option the machine grants also best performances in terms of OEE thanks to the worn-out tool replacement in very short time.

• Robotic loading/unloading of the machine

Each grinding machine is already prepared for an automatic system for loading/unloading parts (a 6-axis robot or gantry device installed in front of the machine can be used), therefore, it is possible to create a fully automatic cleaning cell at further stages, if full automation of the grinding machine is necessary.
