Hyundai VMCs designed for small to mid-sized shops
The unit’s cartridge type spindle lends itself to tool and die manufacturing.
The F750M/960M series vertical machining centres from Hyundai WIA was developed for machining industrial moulds and dies and is ideal for small- to medium-sized job shops, yet capable enough to handle high production environments that run 24/7, the company said. Standard features found on both M-Series machining centres include a 12,000-rpm built-in spindle with a Big-Plus 50 taper spindle nose, thru spindle coolant with chiller, hardened and ground box guideways and HW MP II CNC Mould Package included in the control.
According to the company, the cartridge type spindle is ideal for mould makers. The main spindle is said to deliver minimal noise and vibration even at the highest cutting speeds, guaranteeing stable machining and minimising thermal transmission to the main spindle. Ultra precision class angular bearings provide high-speed acceleration for smooth machining at high rpms, the company said.
Through-spindle coolant is standard on the series. The company noted that this feature is particularly useful for deep-hole drilling where it’s necessary to keep chip flow clear of the cutting surface. Through spindle coolant also increases tool life and decreases cycle time.
It said all guideways are hardened and ground wide-box types for long-term rigidity and accuracy. By adapting the “semi-rising sliding ways” system, the load on the X- and Y-axis slideway is decreased dramatically to enable the VMC’s to hold tolerances and repeatability over longer cycle times. The F960M table is further supported at all times by the use of four box ways and two supplemental way. This allows for a maximum table load of 4,500 kg without any table distortion, the company said.
Hyundai WIA’s F750M/960M VMCs are outfitted with 20-tool (40-tool optional on F750M), side mount swing arm type tool changers. The tool swing arm automatic tool changer and magazine are separated by a shutter system which closes during machining, thus keeping chips and fluids clear of the ATC and magazine, the supplier said.
