Yamazaki Mazak has added to its range of high-volume turning centres with the launch of the new HQR NEO series, which features three turrets and two spindles and has been designed to deliver increased productivity, accuracy and efficiency. Moreover, Mazak says the additional third turret achieves a faster return on investment by reducing cycle time by about 25%, based on an example component produced with a two-turret configuration, adding that the additional tool stations also allow complex parts to be completed in a single setup.
The HQR-200/3 NEO (launched recently at
AMB 2024) is part of a series comprising two spindle sizes and three turrets; and complementing the standard 65mm- and 80mm-diameter bar capacity machines, the HQR-200/3 NEO offers the option of a 112mm spindle bore for bar work up to 102mm in diameter. This capacity allows the machining of prismatic components from bar material using only a turning centre and not resorting to a machining centre to complete.
Enhanced automation features include a redesigned ‘unloading hand’ that contributes to a 20% reduction in unloading time compared to previous models, while the ‘Smooth Oscillating Cutting’ function automatically breaks up chips and swarf to ensure trouble-free machining.
Mazak says easy integration with automation systems was central to the design of the HQR NEO series. “The new models feature an optional bar remnant disposal function to assist with the automatic operation of bar-fed components when using a short magazine bar feeder — and all automation options can be retrofitted in the field. Furthermore, several features have been incorporated to ensure HQR NEO machines maintain high levels of accuracy during continuous machining.
For example, the Ai Thermal Shield function uses advanced algorithms to automatically determine compensation according to fluctuating temperatures, and thereby improve process stability for automated production. The HQR-200/3 NEO and HQR-250/3 NEO are both controlled via the new Mazatrol SmoothG3 CNC, which has three channels and incorporates features designed to simplify programming, machine set up and prove-out, helping operators to intuitively optimise toolpaths, reduce unnecessary tool changes, balance machining time on each turret, and prevent collisions.
Furthermore, the new ‘Synchro Editor Mode’ allows for easy visualisation, as all three turret programs can be presented side by side — and the CNC handwheel can manually jog through the cycle prior to fully automatic operation to identify any potential interference during the prove-out stage. The new HQR machines also benefit from noticeably improved environmental performance.
