KMC- AS series spindle head is thermally symmetrical achieves minimal thermal displacement. Specially designed high-strength square shape cast iron RAM to enhance 32% rigidity and stability of powerful cutting. The crossbeam movement adopts dual servo motors synchronous drive and dual linear scale feedback control. We use S50C imported Japanese high-carbon steel of box way on the crossbeam to balance the hardness of the rail and link-chain type roller bearings, it solves the problems of negative backlash and uneven hardness. The strong rib has excellent resistance to bending and torsion stress.
KMC- AS series can be equipped with a full range of additional heads (30-degree head, extension head, and universal head) to achieve a wide range of applications for multi-face processing. The high rigidity structure is suitable for processing large workpieces with deep recesses, it can also process ultra-high and ultra-thin workpieces with the mutual movement function of the Z (700mm) axis and W (1100mm) axis. The highest Z axis + W axis travel can be optioned to 2600mm.
KM has sold several units to China, New Zealand, Turkey and other countries for processing large workpieces.
UNIQUE SPINDLE HEAD
The spindle head is thermally symmetrical, and the spindle and motor are placed on the centerline of the head, with minimal thermal displacement. Specially designed high-strength cast iron of 400x400 square shape RAM to enhance 32% rigidity and stability of powerful cutting.
CROSSBEAM STRUCTURE
The crossbeam movement adopts dual servo motors synchronous drive and dual linear scale feedback control. We use S50C imported Japanese high-carbon steel of box way on the crossbeam to balance the hardness of the rail and link-chain type roller bearings, it solves the problems of negative backlash and uneven hardness. The strong rib has excellent resistance to bending and torsion stress.
DIRECT-DRIVE OF THE Y, Z, W AXIS
The Y, Z, and W three-axis servo motors are directly connected to the ball-screw end to ensure transmission efficiency and accuracy.
INTEGRAL BALLSCREW MOUNTING BRACKETS
The W-axis equipped with a ball screw, and its head base and column are cast as one body to ensure maximum rigidity and accuracy.
POWERFUL CLAMPING
Powerful clamping devices on both sides of the crossbeam to ensure high accuracy even for heavy cutting.
SLIDING ROLLING COMBINED DESIGN
Roller packs for the movement of carriages are adopted to use on X, Y-axis insert-box ways to increase the feed and rigidity. Thanks to the right choice of material and good solution for the machining process, we can make the machine have a better performance of high rigidity and accuracy.
INNER COOLED BALLSCREW
The X-axis ballscrew is the hollow design and cooling oil continuously flows through the center of it to take away the heat generated by the transmission system efficiency and improve the accuracy. The support seat at the end of the X-axis ballscrew shaft also has a special design for the outer ring of the air-cooled bearing. The cooling method design is unique to all integrated machining centers.
FOUR GUIDEWAY HIGH RIGIDITY STRUCTURE
The machine base has four-box way by sliding and rolling combined design. The central box way for main support is hardened and ground, covered with Turcite-B which features strong absorb ability-enhancing dynamic rigidity. Moreover, the 2-side box way is as same as the central box way but further employs extra roller-type recirculating bearing to strengthen support. This design can get less loading and more tolerance.
EXTERNAL AXIS POSITION FEEDBACK
The ballscrew is driven by a motor and gear reducer for added strength to the axis feed system. The external position feedback pulse coder is coupled directly to the opposite end of the ballscrew. This allows for high positioning accuracy to be maintained by measuring the true rotation of the ballscrew.
FINITE ELEMENT ANALYSIS
Optimized design of main structure through the Finite Element Method (FEM) analysis, to ensure excellent rigidity, suitable for both high speed and heavy-duty cutting.
