Horizontal deep hole drilling machine tools Model 2805P
1. TECHNICAL DESCRIPTION
1.1. Machines are used for precise drilling of holes of 4 - 12 mm diameter in workpieces made of steel, cast iron, bronze and different alloys.
1.2. Specialized machine tools aided for machining of determined workpieces or groups of workpieces may be manufactured on basis of this model.
1.3. Machine tools may be installed to automatic line.
1.4. Machine tools may have one and two spindle execution as standard.
1.5. Dependable upon workpiece machine tools may be manufactured in three or four spindle execution.
1.6. During one working cycle the holes may be drilled with accuracy of Н7 - Н9, and surface quality not less then Ra 1, 6.
1.7. Gun drills are used in the machine tool as cutting tool.
1.8. Gun drill, being installed in spindle, has rotation and longitudinal feed movement. While entering to the workpiece the front part of gun drill is supported by guiding bushing.
1.9. Middle part of gun drill is directed by support, which also minimizes vibration and reflect the coolant with extracted metal chip.
1.10. High-pressure coolant is supplied from coolant tank through coolant collector, spindle, gun drill to cutting zone. It cool the gun drill and evacuate metal chip from workpiece to chip conveyor.
1.11. Being separated from chip coolant is supplied to coolant tank for several filtrations and is supplied again to cutting zone by pump.
1.12. Selected drill depth is controlled automatically by adjusting of micro switches.
1.13. Machine tool has device for protection from overloading, which make automatic tool removal from hole and switching off the machine tool.
1.14. Safety micro switches and stops limit maximum travel of spindle stock platform.
1.15. Special device will release machining cycle only after installing and clamping the workpiece.
1.16. Automatic switch off of spindle rotation and feed will take place in case of extraordinary pressure reduction in hydraulic system of machine.
