ARBOGA A 4008 M, ELM
The drill head is fixed and is available with or without automatic spindle feed.
The gear box is built according to our experienced methods for highest possible torque. Helical gears combined with steel gears against reinforced fiber gears in the main gear box ensure higher operating efficiency, a more powerful drive mechanism and smooth operation. The noise level and maintenance on the gear box is reduced to a minimum.
Power feed (M)
The power feed is provided with an automatic overload protection device, which starts when the drill pressure becomes too high. When overload diminishes, the feed is automatically re-engaged. When the set drill depth is reached, the spindle will automatically return to the starting point. The feed can also be interrupted manually.
Automatic feed (ELM)
The start/stop function of the automatic feed is fitted with electromagnetic clutch, giving push button operation. The push buttons are situated at the top of the three feed levers. Hand and automatic reversing for tapping are standard.
The machine is fitted with a fixed table 500 x 400 mm as standard, mounted on a rigid arm and adjustable 360° around the column. There is an adjustable crank on the front side of the table arm for elevating and lowering the table to the correct working height.
The spindle is made from steel, with the lower spindle roller bearing being located as near to the lower part of the spindle as possible, ensuring greater precision and rigidity, even in milling operations. It is further adjustable by the journals in the bearings, which guarantee very small tolerances. The spindle is fitted with a counterbalanced tension spring and is adjustable depending on the weight of the tool.
The column is constructed of steel, which ensures extra rigidity of the machine, giving accurate precision and a minimum deviation from the stipulated angle between the drill and the table.
The machine is equipped with thermal overload switch, no-volt release and emergency stop.
