- Variable Speed Control: Allows the operator to adjust spindle speed to match the material and drill bit size, optimizing drilling performance and tool life.
- Digital Indicator: Displays the rate of spindle rotation in RPM, providing precise control.
- Down-Feed Handle: Used by the operator to move the quill down and up.
- Adjustable Table: The worktable can be positioned at varying heights and rotated 180° in either direction. It features T-slots for clamping workpieces.
- Gear Rack: Engages the table for height adjustment.
- Work Light: Provides adequate lighting for the work area.
- Depth Scale Lock: Locks the position of the depth scale for consistent drilling depths.
- Coolant Shut-Off Valve: Controls the volume of coolant, which is crucial for drilling certain materials and extending tool life.
- Emergency Stop Button: Immediately stops all machine functions in an emergency.
- Safety Guard: An adjustable guard with a limit switch ensures safe operation, preventing the machine from running if the guard is not in place.
- Reversible Spindle Rotation: Essential for tapping operations.
Installation and Setup:
- The machine requires a level, concrete floor for installation.
- Proper anchoring to the floor is necessary for stability and safety, using bolts and expansion plugs.
- The power supply should be located close to the machine to avoid tripping hazards.
- Adjusting the Machine Head Height: Involves unlocking the table by turning the crankshaft, placing wood under the head, raising the table, loosening set screws, and then safely securing the head.
- Adjusting the Gear Rack Height: Involves locking the table, unlocking the column bearing, raising the gear rack, and then locking the column bearing.
Operation:
- Drilling: Involves loading and securing the workpiece, securing the drill bit in the chuck, unlocking and adjusting the table, adjusting the safety guard, and selecting the transmission mode. The drilling depth is set using the depth scale indicator.
- Tapping: Similar to drilling, but requires selecting the tapping position on the selector switch and using the reverse button (AD) to reverse the spindle rotation after reaching the desired depth.
- Removing Tooling: Involves disconnecting power, placing wood on the table for protection, positioning the worktable under the spindle, and using a drift key to tap out the bit or chuck arbor.
