Precision Gear Change Pitch Control Tapping Machine

The Brief of Machine

Vertical Double Spindles Drilling Tapping Dual Purpose Machine Tool is the mature machine in our factory. The machine solves the prior trouble which can't finish drilling, tapping at one time. After workpiece fixed, it can be processed drilling, reaming, chamfering and tapping quickly, it is high efficiency and energy saving.

The machine is easy to operate; it is no need to professional staff. Our company accumulates from Since 1958 professional technology and strict quality control.


  • Suitable for mass production of processed, it is high efficiency and the drilling and tapping are done at a single time.
  • The Structure of the machine body is concise with excellent rigidity.
  • The spindles adopt quality steel and was hardened by the treatment. It is high precise grinding, and excellent abrasion resistance.
  • The left and right movement of the worktable is controlled by pneumatic system.

Main Devices of the machine

  • Belt changing and tensioning device are provided for speed changing and belt tensioning.
  • The left and right spindles are adopted neoprene transmission for two spindles synchronous rotation.
  • Automatic resting mechanisms for the left and right spindle keep the spindle at the ready I for machining state for saving time.
  • Elevating handle is for the up and down movement ofthe table.
  • Buffer positioning block and positioning stop are for accurate positioning ofthe table.
  • Locking mechanisms are provided of the knee and middle saddle for guaranteeing machining accuracy.
  • The air devices is for automatic control and reliability.

Operation of the machine

Selection spindle speeds

Select the speeds according to the workpiece need, changing belt positions according to speed plate.

1. Changing of belt positions

cutoff power supply for changing bell positions.

Loosen locking screw (4) - Loosen belt - Change belt position . Tension belt . Tighten locking nut

2. Spindle feed

Press down spindle feed handle for drilling, milling or tapping.

3. Cross and longitudinal feeds of the table

Turn the table cross feed handle for table cross feed. Longitude feed is controlled pneumatically.

4. Drilling, Milling, Tapping

  • The right spindle is for drilling, milling and counter boring. The left spindle is used for taping, and also for drilling and counter boring. After champing the work piece, turn on the motor, and press switch, pull down the feed handle (20) of the right spindle for drilling and milling. After the spindle has returned to its original position. The table moves leftward and positions pneumatically, making ready for tapping.
  • Pull down the feed handle of the left spindle for tapping. When tapping to the required position, the motor reverses direction and the spindle returns to its original position, the table moves leftward and position pneumatically, making ready for tapping.
  • Load a new workpiece and repeat the above operation.


Power of this machine adopt 3 phase and 4 cables. Power cable should be above 2.5 mm2. Power supply for this machine should be 3 phase, 38ov, SOHZ and its capacity should be above 2oA. The machine must be grounded firmly for Protecting the operator.

Power of the customer should be connect with the power terminal via the automatic air switch for cutting off power supply for maintenance.


Warning !

Ground wire with a diameter above 2.5mm2 should be connected firmly at the position to protect the operator.


Be sure to connect the zero line and phase conductor correctly, otherwise the electric system will be damaged.


Stop the operation cut off the power supply for changing the tool.

Warning !

When operate machine, it is forbid to wear loose coat and use glove, pls put long hair in hat, wear safe shoes and goggles.



Check the electrical system after cutting off the power supply.
