Large Capacity VMC for Mold/Die Work

New Face of Mold Machining: The F750M/960M CNC vertical machining centers are ideal for small to medium sized job shops, yet capable enough to handle high production environments that run 24/7.

Hyundai WIA Machine Corporation (Carlstadt, NJ) introduces two all new large capacity CNC vertical machining centers developed for machining industrial molds and dies, the F750M (travels of 61 in X-axis, 29.5 in Y-axis, 28.5 in Z-axis) and F960M (travels of 96.5 in X-axis, 37.4 in Y-axis, 33.5 in Z-axis).

Standard features found on both M-Series (M=Mold) machining centers include 12,000 rpm built-in spindle with Big Plus 50 taper spindle nose, thru spindle coolant with chiller, hardened and ground box guideways and HW MP II CNC Mold Package included in the control.

Main Spindle
Both the F750M and 960M feature a 12,000 rpm built-in cartridge type spindle which is ideal for mold makers. Ultra precision class angular bearings provide high speed accel/decel for smooth machining at high rpm. The main spindle delivers minimal noise and vibration even at the highest cutting speeds, guaranteeing extremely stable machining and minimizing thermal transmission to the main spindle, and with the use of a hydraulic tool lock system machining stability has been increased.

The standard Big Plus spindle system (BBT #50) provides dual contact between the spindle face and the flange face of the tool holder. This greatly increases tool rigidity, reduces run out and adds significant productivity to any machining application. Spindle motor is 16 to 25 hp with spindle torque rated at 893/732 Nm. The Big Plus spindle offers users the fastest possible material removal rates, highest accuracy and excellent rigidity. It guarantees stability when run at high spindle speeds for high rpm precision machining.

Standard Thru Spindle Coolant
Thru spindle coolant is standard on the F750M/960M Series. This feature is particularly useful for deep hole drilling where it’s necessary to keep chip flow clear of the cutting surface. Thru spindle coolant also helps to increase tool life and decrease cycle time.

Bed Structure
All guideways are hardened and ground, wide box type for unsurpassed long-term rigidity and accuracy. By adapting the “semi-rising sliding ways” system the load on the X- and Y-axis slide way is decreased dramatically enabling the M-Series VMCs to hold tolerance 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 ways. This allows for a maximum table load of 4,500 kg without any table distortion.
