MM-330 MILLING MACHINE

The 330 AUTOMATED MILLING MACHINE is designed to make holes with various profiles, T milling, etc. in pieces of plastic (e.g. plates, dashboards, bumpers), using cutting tools.The machine performs the required milling on the pieces loaded manually. The piece can be of two or more types (e.g. RH drive dashboard, LH drive dashboard). For these machining operations, there are two fixtures, which are placed in positions accordin to the machining required, as selected by the operator.

 

SAFETY DEVICES

  • The safety devices handled by the CPU SAF integrated in the PLC, which manages
  • the emergency button on the main keypad
  • the emergency button on the operator’s side
  • the emergency button on the station access door side
  • the internal emergency button of tool changer area station
  • Safety door on the operator side

Motors:

  • Electric spindle motor, installed on the robot wrist, allows for the rotation of the tool. Asynchronous controlled by inverter
  • Chip discharge conveyor motor. Asyncronous without inverter
  • Safety door moving motor

Sensors:

  • photocells that check positioning on fixtures
  • tool profile control sensor
  • tool height control feeler pin
  • cylinder reeds (each cylinder has two positioning reeds)

Interface:

The machine-operator interface is managed through touch display on which are handled the machine parameteres, the manual controls and that displays the operating status/alarms.

There is also the safety device reset button, guard opening request, start and stop automatic cycle buttons.

MACHINING STEPS AND MAIN FEATURES

  1. Before and after machining, a tool integrity check is run by an optical sensor. If the check outcome is not successful, an alert is generated to prevent machining start
  2. In the next step is carried out a check of the correct mounting of the tool: the robot moves on a feeler pin to check that the milling machine does not exceed the correct height
  3. The home position of the robot is the tool integrity check position. There is also a tool changer position of the robot
  4. To the robot wrist is applied an electric spindle that performs the milling operation, aling with a blow of ionized air for chip removal
  5. In the fixture area are installed two locking cylinders for each fixture (possibily also the suction cups that lock the entire work piece)
  6. In the operator area is installed a chip extractor that cleans the fixture. When the suction pipe goes out from standby position, the suction fan motor starts
  7. Under the fixtures is installed a chip extraction conveyor
  8. To protect the operator, in the front area is installed a motorized safety door, that moves down before machining starts
