The Fanuc Arc Mate robot has been used at the centre of a robotic welding cell engineered by Cyber-Weld for Norbar Torque Tools. The system has provided Norbar with increased capacity, quality improvements and space savings.

Norbar had been using a welding cell with limited capabilities for many years. As the cell had come to the end of its effective supportable days, Norbar searched for a solution that would enable it to speed up the welding process for its industrial torque wrench range.

Cyber-Weld, a strategic partner of Fanuc for welding applications, was selected to engineer and supply the replacement system. Designing what is essentially a ‘plug-and-weld’ robot cell comprising a Fanuc Arc Mate six-axis welding robot, an integrated MIG welding power source, a turntable and fume extraction, the system was delivered as one complete product and forklifted into position.

Requiring only power and gas supplies, the system was available for pre-production trials and commissioning within hours of its delivery.

The cell’s walls and ceiling form a box or room that neatly self-contains all equipment. The turntable is manually rotated in front of the robot to present parts for welding and to unload welded components.

Key benefits of product application

  • With Norbar’s existing welding cell, the welding process produced a lot of spatter, which required a lengthy linishing operation. Cyber-Weld’s system reduced spatter, virtually eliminating the need for linishing after welding.
  • The Cyber-Weld system features high welding speed and the ability to multi-load components while welding continues, allowing Norbar to reduce a typical batch weld time from 4.5 hours to 2.5 hours.
  • The weld cell allows ease of access to all areas without compromising available space. Quick-release post mounts with pin locking ensure fast tool changeover.
  • The success of the system, its transition and minimal disruption to production is down to the preparation Norbar carried out with Cyber-Weld, according to Norbar production engineer John Hooley.

FANUC UK provides industrial automation solutions ranging from the supply of CNC controllers, robots, drilling machines, EDM and injection moulding machines through to the complete integration of factory automation systems.

Providing a single customer support portal for its three core businesses, FANUC comprises FA — CNC controllers, motors and drives; robotics — industrial robots and systems; robomachines — EDM, injection moulding and drilling machines.

CNC

FANUC’s FA business manufactures CNC controls, drive systems and laser systems. With a 65 per cent market share in the global CNC control sector, FANUC is the market leader. FANUC CNC is the controller of choice for the world’s leading machine tool manufacturers; continuously developing functionality sees FANUC CNC control being used in a wide range of applications — combining powerful control and high precision with unparalleled reliability.

FANUC servo drives and motors are well proven — aimed at the machine builder, they offer the widest range of high-performance compact designs.  The high availability and ease of maintenance together with world-class, energy-efficient designs make them the motors of choice for thousands of OEMs around the world.

Robotics 

FANUC’s robotics business manufactures the widest range of robots in the world for applications from micro-electronics assembly to the forging of precision aerofoils for jet engines — in industries as diverse as pharmaceutical and potato processing — and with maximum payloads from 1kg to 1,350kg. More than 280,000 FANUC robots are operating worldwide, with production currently geared to meet demands of 5,000 per month. FANUC robots are truly ‘out-of-the-box’ automation designed to be totally flexible and, with application-specific options, straightforward to integrate.

Robomachine

FANUC’s robomachine business manufactures Robodrill machining centres, Robocut EDM machines and Roboshot electric injection-moulding machines. Using FANUC components throughout, the robomachine business builds on the advanced technology, reliability, energy efficiency and innovation of its own controllers, drives and motors. With a focus on energy efficiency and high reliability, the robomachine business developed the first all-electric injection-moulding machines — Roboshot — changing the mould shop into a much cleaner and quieter environment.

Customer support

From initial sales contact with FANUC through the life of the product, FANUC provides one single contact point to make sure support is always at hand with up-to-date advice, genuine warranted parts and, whenever possible, obsolescence avoidance solutions that ensure the lifetime delivery of maximum efficiency.
