Rigid spindle for HMC

March 1, 2004
The spindle of the M-H4050 HMC uses four rows of front spindle bearings, instead of two, for rigidity at all speeds. Thermal stability comes from control of heat sources — internally oilcooledballscrews, oil-cooled flange mounts to isolate servomotor
The spindle of the M-H4050 HMC uses four rows of front spindle bearings, instead of two, for rigidity at all speeds. Thermal stability comes from control of heat sources — internally oilcooledballscrews, oil-cooled flange mounts to isolate servomotors, oil-cooled spindle housings and motors, and in-line couplings to thermally isolate spindles and servomotors. A three-point-supported bed and roller-type guideways provide even more rigidity.

Waterjet equipment

Streamline SL-IV Plus waterjet intensifiers feature a long-lasting Hyperlife plunger seal and ceramic plunger, both of which boost uptime. A hard-seal end cap improves maintainability. The SL-IV Plus provides 60,000-psi continuousoperating pressure which, reports the manufacturer, increases cutting speed up to 20% over conventional systems without sacrificing edge quality.

Radio probe beats interferences

The RMP60 machine tool probe uses frequency-hopping, spread-spectrum radio transmissions (FHSS) for probing 5-axis, large-part, or deep-part machining. The system "hops" transmission between multiple, discrete 1-MHz channels to overcome interferences. FHSS also lets multipleprobe systems and other industrial equipment coexist in "noisy" environments.

Toolpath for tight corners

The Curly Corner toolpath in the upcoming FeatureCAM 2005 software uses a trochoid path through slots and in tight corners to maintain high speed with a more consistent cutter load.It controls the cut width in sharp corners and slots and eliminates sharp transitions in cutter direction. The toolpath adjusts the maximum tool load in proportion to the stepover size for performance.

Universal machining

The milling head of the DMC 60 T 5-axis machining center ensures its universal nature in two ways — a 37.5-hp, 12,000-rpm spindle and a B axis with interpolation and 30°-swivel range in each direction beyond the horizontal or vertical for negative angle machining. The B axis is pretensioned by a spur gear for distortion-free power transfer.

HMC features twin pallets

The HMC 400 horizontal machining center's twin 400-mm-diameter pallets lock onto a simultaneous, fourth-axis rotary table with a 13,000-lb holding force. A double enveloping gear on the table and mechanical disk brake with 12 pads ensure ±5-arc sec accuracy and ±1-arc sec repeatability. The pallets feature 20 3 24 3 20-in. X/Y/Z travels. The HMC 400 also features a 10,000-rpm spindle with 1,200-ipm travel rates; heavy-duty, flame-hardened boxways; and rib-reinforced castings.

VMC drive connects to spindle

The VM-3 moldmaking VMC sports a 40-taper, 12,000-rpm spindle that uses a special in-line, direct-drive system that connects the motor directly to the spindle for less vibration, heat, and noise. Coolant circulates through a jacket in the machine's head casting for thermal stability. The headstock is also lined with insulating material that prevents radiated heat from affecting the casting. Air circulates through the entire assembly for additional cooling. An electronic thermal-compensation algorithm in the VM-3's control models ballscrew heat and corrects for any expansion that could cause positioning errors.

Multitasking machine tackles aluminum

The Nexus QTN-250MS multitasking machine features 35-hp, 4,000-rpm advanced integralspindle/motor technology on its main turning spindle for heavy-duty metal removal and high-speed cutting of aluminum and other nonferrous materials. The second spindle has a 6-in. chuck, 10-hp output, and 6,000-rpm maximum speed. An additional rotarytool spindle delivers 7.5 hp and 4,500-rpm maximum speed.

Machine design dampens vibration

The NV4000 VMC's net driving force acts through the center of the axis. The machine features five ballscrews — two on the Y axis, two on the Z, and one on the X — that reduce vibration without sacrificing speed for accuracy. A more-stable platform improves rigidity on all axes and lets machining forces travel across the machine's arch-shaped column and through its bed, forming a closed loop.

EDMs sport new NC

The Roboform 350 die-sinking EDMs feature a new generation of numeric controls. Called Dynamic Process Control (DPControl), it suggests ideal electrode undersize, determines the number of electrodes needed, and organizes jobs according to preset priorities. The system's graphics illustrate all machining operations, and electronic manuals give operators easy-to-understand information about the current function.

Grinder performs I.D. and O.D. work

The S33 universal cylindrical grinder addresses both internal and external applications in a single machine platform. Its center height is 175 mm and between-centers grinding length is either 650 mm or 1,000 mm. The O.D. wheel size is 500 3 80 3 203.8 mm, and chuck capacity between centers is 130 kg. The basic wheelhead indexes at 0° or 30° for straight and angular plunge grinding, and the universal turret wheelhead swivels manually or automatically for external, internal, and face grinding.

CMM measures without the extras

The 7-axis contact/noncontact Laser ScanArm measurement device collects measurement data without third-party attachments, external electronics, or cables. It uses a hard probe to collect simple point variations and a laser scanner for larger data volumes. An auto-material feature samples workpiece surfaces and adjusts the scanner's settings for optimal use. The device also has infinite rotation.

Detect part errors before machining

Vericut CNC machine simulationandoptimization software's latest version includes an Auto-Differencing function that compares cut stock with the design model to locate errors and differences. It also features tools for creating custom reports and a cuttinggraph display to analyze cutting conditions. An X-Caliper measurement utility digitally verifies cut part dimensional accuracy before the NC program loads onto the machine.

Five-axis machining software additions

PowerMill 5 software sports secondary-axis limiting so the generated program does not move outside any limits in the machine tool's movement range. Contact-point analysis ensures the cutting surface touches only the component. The contact-point feedrate control makes sure feedrates are based on cutting speed instead of the tool tip's rotation rate.
