The Roscamat Tiger is a bench mounted arm tapping machine for the production of accurate threads. It is designed to quickly and easily complete tapping operations, allowing the user to efficiently complete work on the bench.
The Motor and Drive System
The Tiger is powered by an electric motor which provides a controlled amount of torque to the spindle. This is then increased or decreased depending on the size of the tap and the type of material it is being used on. The speed of the motor is set prior to use, in contrast to hand tapping where the operator’s feeling would dictate the rate at which the tap enters the work.
The Floating Chuck and Automatic Reversal
The machine will reverse and withdraw the tap from the work when the preset depth is reached. The chuck is floating so is able to compensate for any axial play within the work, thus preventing the tap from being subjected to side force as it is withdrawn from the hole. This ensures that accurate threads are cut and that the tap does not get damaged.
The Articulated Arm and Positioning
Instead of having to move the work around the machine, the arm is swung out to the side until it is directly above the required hole. Because the arm is counterbalanced it will remain exactly where it has been put, returning to its rest position after the tapping process has been completed. When dealing with large numbers of holes for tapping within a production environment, this type of arm makes a huge amount of sense.
Tap Size Range and Material Compatibility
Roscamat Electric Tapping Machines in the Tiger range are designed to be used with a variety of different tap sizes. Typically the range of tap sizes that can be used in a Tiger tapping machine will range from M3 to M12 depending on the specific model. As with any tapping operation, the type of material being tapped will have an effect on the type of tapping machine required. Most tapping machines are designed to be used with a variety of different materials such as steel, aluminium, brass, and other similar workshop materials. However, very hard alloys, for example, hardened steel, and large threads are best completed using a heavier duty tapping machine.
Safe Operation in Practice
In addition to following the safe use of work equipment and machinery guidance from the HSE, when using the Roscamat Tiger there are a number of key points to bear in mind for safe operation. These include setting the required depth stop prior to tapping, ensuring that the workpiece is correctly clamped or fitted so as not to rotate, and use of the supplied foot switch to leave both hands free to correctly position the tapping arm.
