Constant developments in CNC machining technologies have virtually transformed the automotive manufacturing concept in the global market. Enhance productivity, world class quality and superior finish can be achieved through improve machining, alternative process, state-of-the-art automation, tooling equipment and increase use of robots, robotics systems and controls. Various innovative solutions are being offered for machining of engineering components, the same are highlighted here.
Double Head Spindle CNC Turning CentresDouble head spindle CNC turning centres are the most productive cost effective machines for turning operations on chucking jobs like gear blanks, pump parts, fan parts, hubs, break drums, bearing rings, valves, and bushes etc. These machines have two heads facing each other with one main slide (Z-axis and cross slide X-axis). These machines are provided with linear tooling system with up to six tools for each head.
Advantages of Double Head Spindle CNC Turning Centres• No idle time: Resulting in higher productivity• While machining: Saving of machine time & saving loading and unloading time• Two set-ups: Set up 1 & 2 is finished on the same machine, ready to dispatch• Manpower: Saving manpower cost & saving space on shop floor• Linear tooling system: Helps faster positioning of tools compared with turret • One operator can easily operate around 4-6 machines• Precise CNC controlled movement of gripper/loader ensure correct butting & clamping and eliminates rejection• Obtain predictable output because elements like operator exhaustion, clamping error, etc. are eliminated.
TwinturnTwinturn machines are the most productive double spindle machine and the much better option than two independent single spindle machines.
Advantages• Machine with 8 station turret on first side and linear tooling system on second side for optimum production• Most productive double spindle CNC lathe are designed to be operated by single operator• Objectives of developing Twinturn Series CNC two-in-one turning centre’s are:• Maximising output per shop floor space (work envelop of machine is 60-65 per cent of 2 nos. single spindle machines) • Maximising output per skilled operator.
Super Precision CNC Turning CentresThese machines have been specifically designed for the precision hard turning to replace grinding process of hardened components.
