Beltless design for no backlash
The Puma MX 2600ST is a mill turn machine capable of producing parts up to 29.9 in. (737 mm) diameter by 59 in. (1499 mm) long.

Powering the machine's turning component is a 35 hp, 4,000 rpm, high torque spindle motor. The motor is mounted on the headstock casting with the armature on the spindle O.D. This beltless design eliminates backlash, feedback error and vibration, resulting in longer tool life, less maintenance, high precision, and superior finishes. Driving the milling component is a 12,000 rpm, 30 hp motor.

The lower tool turret can accommodate live or static tools at any of its 12 stations, and be oriented toward either the main or sub-spindle. A 6.7 hp motor turns the live tools at speeds up to 4,000 rpm. The turret is non-lifting to protect the coupling from chips and other contaminants, and indexes station-to-station in 0.2 seconds. Milling tools are housed in a 40-tool ATC; an 80-station ATC is optional. Tool-to-tool change is 1.8 seconds.  

The MX2600 combines a B axis (tilting) with Y axis to expand the number of geometries that can be machined without using customized rotary toolholders. It can cut, drill or tap above or below centerline, machine angular features, and provide a solid platform for heavy duty machining. A rigid, three piece curvic coupling locks at 5° increments, while the RGC provides extra rigidity in 0.001° increments.

Fine-grain Meehanite castings absorb vibrations and inhibits thermal distortion and twisting. Three linear guideways on the upper carriage Z axis provide rigidity and alignment during tough cuts without lift or torsion that might otherwise compromise accuracy. The bed’s torque-tube construction prevents twisting and distortion during heavy cuts, and provides a through-the-machine conduit for cool air.

Four machines in one
Hyundai WIA's new series of twin spindle multi-tasking CNC turning centres, the LM1600/1800TT, feature upper and lower turrets and available Y and C axes, allowing for the processing of complex parts in volume production runs. The new series is four machines in one—two lathes and two mills. They feature high power built-in spindle motors and upper and lower turrets for high productivity. Precise synchronized facing twin spindles reduce idle time, and BMT-type turrets guarantee accuracy and power. 

The LM1600/1800TT series features a 45° slant bed design. The pretensioned and double anchored design provides outstanding positioning and repeatability with virtually no thermal growth. Rapid high speed axis movement is achieved by the use of linear motion guideways in the Z axis, complimented by box guideways in the X and Y axes, for added rigidity. Rapid traverse: X1/X2 axes, 20/20 m/min (787 ipm); Z1/Z2 axes, 40/40 m/min (1575 ipm); and Y axis, 7.5 m/min (295 ipm).

The upper turret on the TTY and TTSY configured machines use a wedge-type Y axis, which permits machining of complex parts in a single chucking. With a Y axis travel of +/- 50 mm (100 mm [3.94 in.] total), a wide range of workpieces can be machined. 

Built-in spindle motors for left and right with identical specifications allow for high speed precision machining in either direction. Each spindle features angular bearings for high speed accel/decel as well as smooth machining with minimal noise and vibration at high rpms, even at the highest rotational speeds. Spindle temperature is further controlled by the use of a spindle chiller. Left and right spindle specifications are equal 6000 rpm, 15/11 kW, A2-5 with 208/140Nm of torque on the LM1600TT and 5,000rpm, 22/11 kW,  A2-6 with 358/214 Nm of torque on the LM1800TT.
