Pneumatically powered tapping machinery, also referred to as pneumatic threading machines or threading arms, is used in the process of cutting a thread inside a metal hole. This hole can then be used to thread a bolt or screw and can also be used for making the threads on nuts. The machine consists of a parallel arm that can be attached to a workbench, a spindle which is driven by compressed air and different size tap adaptors that can be used for different size projects. Pneumatic threading machines are also equipped with quick-change holders and safety slip covers which can range from sizes M3 to M12.

What are the Benefits of a Pneumatic Tapping Machine?

The main benefit of a pneumatic tapping machine is the ability to cut threads safely, quickly and with greater precision than any other method. Before the invention of the tapping machine, workers would have to use a cordless drill combined with a spiral hand tap which would take a lot of concentration, strength and precision to operate. This old-fashioned method also led to a greater incidence of errors and the waste of valuable materials.

Many companies now report that using a pneumatic tapping machine gives them greater productivity when manufacturing and reduced mental and physical fatigue for workers undertaking threading tasks.

The Use of Compressed Air in a Pneumatic Threading Machine

Pneumatic threading machines also contain a compressed air unit. This is made up of a mist lubricator and a compressed air filter which can be adjusted using the upper adjustment knob. To increase the pressure, the knob must be turned clockwise and to decrease the pressure, the knob must be turned anticlockwise. To ensure that the pressure remains constant, the knob can be fixed in the starting position to prevent accidents. When the pressure is below 0.7kg/cm2, dust and water are automatically removed so the compressed air remains filtered. The purpose of the mist lubricator is to mix the oil with the compressed air and the amount of oil can be changed via the oil adjustment screw.
