The CMA CNC FTC automatic tapping centres are characterized by a 3-axis (X, Y, Z) moving head. They are designed for drilling, tapping and countersinking sheet metal from laser cutting. The innovate floating head system is designed and manufactured by CMA. It is capable of absorbing deviations in workpiece positioning of up to 1mm, thus avoiding core breakage.
Each and every operation is perfectly programmable via a PC controller with CMA's own CNC software (TapCam) with the possibility of importing 2D/3D files and automatically converting them into the machine's ISO codes.
The table is designed with Ø28 holes to offer significant advantages. They provide solid anchor points to securely attach mooring systems. The holes are also used as reference points to establish the zero point. By using the same reference and anchor points, the time required to change from one workpiece to another is greatly reduced. This increases machine efficiency and reduces downtime.
The spindle is guided along the table on hardened precision linear guides mounted on the body of the machines. The X-axis is driven by a helical rack and pinion and the Y and Z axes by a self-lubricating ball screw.
