CNC Machining
High-productivity CNC machining requires eliminating secondary tapping operations from the main spindle. For plant managers and operations executives in the European metalworking sector, maximizing the profitability of a CNC machining center is an absolute priority that defines the workshop’s competitiveness. Keeping a high-investment cutting infrastructure occupied with simple tasks like subsequent tapping or deburring drastically reduces Overall Equipment Effectiveness (OEE) ratios and unnecessarily increases the cost per piece. The integration of Roscamat’s articulated arm systems acts as the perfect peripheral solution: it allows outsourcing tapping to a weightless secondary cell, ensuring that the numerical control spindle works exclusively on complex roughing, milling, and contouring operations that bring true added value to production.

Maximization of OEE and elimination of bottlenecks in the industrial workshop
The optimization of workflows in the advanced manufacturing environment relies on the suppression of downtime in turning and milling centers. When a CNC Machining process is systematically interrupted to execute repetitive threads, the amortized cost per minute of the main machine penalizes the project’s net margin. Roscamat electric tapping machines absorb this workload in a parallel station operated in hidden time, which increases the overall production capacity of the plant without the need to acquire expensive additional machining centers.
This peripheral strategy neutralizes one of the most critical risks in machine workshops: scrap or discarding complex dies due to fractured cutting tools. If a tap breaks inside a metal block that has already accumulated hours of high-precision CNC milling, recovering the part is usually unfeasible or extremely expensive. By delegating this final phase to our electromechanical arms equipped with active safety clutches, any anomaly in the mechanical torque stops the operation before damaging the component, safeguarding the previous investment made in the main line.
Synchronous servomotor technology for absolute dynamic rigidity
Faced with the limitations of conventional pneumatic tools, which are prone to atmospheric pressure drops and loss of motor torque at low revolutions, Roscamat implements high-frequency electric servomotors. This cutting-edge motorization provides a linear and constant force delivery across the entire speed spectrum, providing the spindle with impeccable dynamic rigidity. This precision allows processing everything from highly ductile materials to refractory and high-hardness alloys very common in the aerospace, biomedical, and automotive sectors with total safety.
Roscamat’s architecture of gears and planetary reduction modules allows industrial purchasing engineers to select the exact configuration ideally suited for their plant needs. Our systems range from ultralight chassis optimized for the fast cycle of small threads, to heavy industrial stations that combine robust mechanical transmissions to cover large-caliber tapping. This adaptation eliminates premature fatigue of mechanical components and shields dimensional accuracy throughout extended campaigns of continuous industrial production.

Positional flexibility with orientable heads and millimetric digital control
The modular kinematics of Roscamat parallel arms, built with lightweight structural alloys and balanced by dynamic gas struts, provides real weightlessness in the work plane. The operator can move the head along wide outreach radiuses fluidly and with barely any physical resistance, minimizing the risks of occupational fatigue and strictly complying with European regulations on ergonomics in the workplace.
For those complex geometries that emerge from CNC machining operations with transverse or inclined holes, the VH-type multi-orientable articulated head offers absolute versatility. This mechanism allows pivoting the motor plane to ninety degrees manually and safely, facilitating the immediate transition between vertical and horizontal tapping without having to unclamp or flip the base piece on the technical bench. Furthermore, the integrated digital touch screen allows programming the depth in the Z-axis with micrometric precision; upon reaching the target coordinate in blind holes, the motor automatically reverses the rotation direction, guaranteeing perfect threads and eradicating human error.

Frequently Asked Questions
How exactly does Roscamat help improve the profitability of a CNC machining center?
A CNC machining center has a high hourly cost due to its technological complexity. If you use that spindle time to perform simple tapping operations, you are losing money. By incorporating a Roscamat arm alongside the CNC, the operator can tap parts in hidden time while the main machine continues milling the next block, doubling the real productivity of the station without adding waiting times.
Can electric arms be integrated into robotized industrial production cells?
Yes, fully. The electronic architectures and digital modularity of Roscamat automatic tapping machines allow their integration into connected flexible manufacturing cells. Digital motor torque control and depth sensors facilitate communication with industrial robots or collaborative arms (cobots) to automate the part feeding and unloading flow in Industry 4.0 environments.
What advantage do the safety clutches of Roscamat quick-change collets offer?
Each tool holder collet incorporates an adjustable mechanical clutch calibrated according to the tap metrics. If the pre-drilled hole has a burr, the diameter is incorrect, or the bottom of the blind hole is packed with chips, the clutch slips instantly, stopping the torsional force. This avoids tap breakage 100%, saving the tool and preventing the part coming from the CNC machining process from ending up in the scrap bin.
What maintenance does an electric tapping arm require compared to a pneumatic one?
Maintenance is substantially lower and cleaner. Pneumatic systems require exhaustive air filtering to purge moisture and demand constant line lubricators that contaminate the workshop environment. Roscamat high-frequency electric arms use brushless servomotors and self-lubricated sealed bearings, reducing technical interventions to routine checks of the gas strut and basic structural cleaning.
