VMC for Small Job Shops or High Production 

Hyundai WIA America Corporation (Carlstadt, NJ) announces its latest addition to the wildly popular Value Master range of CNC vertical machining centers, the F650VM. Developed to offer premium performance at an affordable price, the F650VM (X-axis, 51.2 in, Y-axis, 26.4 in and Z-axis, 25 in) is bundled with an impressive list of high-performance options as standard.

Standard features include a 30-tool swing arm tool changer, Thru Spindle Coolant, Big Plus Spindle,-Rigid Tapping and a 10.4 in color LCD.

More significant, Value Master machining centers are all built upon the same ridged foundation. The bed, column and saddle of the Value Master Series are designed using finite element analysis (FEA) to ensure powerful cutting and agility and are composed of meehanite cast iron to minimize deformation when performing heavy-duty cuts. The rigid bed is designed to absorb vibration for stable machining.

In order to eliminate thermal growth during machining, all axes are driven by high precision double-nut ballscrews. The double pretension design provides outstanding positioning and repeatability with virtually no thermal growth. All ballscrews are connected directly to the servo drive motors without gears or belts, eliminating backlash.

Rapid high speed axis movement is achieved by the use of linear motion guide ways in all three axes. This reduces non-cutting time and decreases machining time for greater productivity. Rapid traverse: 1,418 ipm (36 m/min) in X- and Y-axis and 1,182 ipm (30 m/min) in Z-axis.

The standard Big Plus spindle system (BBT #40) 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 applications.

The F650 Value Master is configured with a 25 hp, 10,000 rpm spindle for taking deep cuts at high speeds. Ultra precision 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.

To make the Value Master F650VM a true performer, Thru Spindle Coolant is a standard feature that 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.

Value Master VMCs are outfitted with 30-tool, side mount swing-arm type tool changers. This technology offers optimal performance with impressive tool change times of 1.5 second, tool-to-tool. With a capacity of 30 tools (plus one in the spindle) setup time is reduced and run times can be longer, especially if loaded with redundant tools. The 30-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.

When a tool change is required, machining stops, the shutter opens, the ATC exchanges old tool for new, the shutter door then closes and machining begins again.

The F650VM is easy to program and operate with its start-of-the-art Fanuc i-Series CNC control featuring a 10.4 in color LCD display as standard. As the industry’s most popular control, Fanuc offers compatibility and bullet proof reliability. The Value Master F650VM is ideal for small to medium sized job shops, yet capable enough to handle high production 24/7 environments.
