This machining center is designed to minimize vibration and heat when the spindle spins at a high speed and enable quick increase or decrease of speed. Also, the main spindle is supported by P4-level high precision bearings and maintains stable precision even under fast high-duty operations.

The refrigerated cooling system maintains a uniform spindle temperature required for high accuracy and minimizing thermal extension. Thermo sensors regulate the temperature of the oil which is circulated through oil jackets around the spindle bearing and motor housing.

This system makes it possible for simultaneous dual contact of the taper and spindle front side by using elastic deformation of the spindle and implementing perfect control of the gauge.

-  The tool contacts the spindle front side and taper simultaneously. → Rigidity is enhanced and vibration reduced.

-  The machining performance and surface roughness are improved under even the worst conditions.

- The existing tool can be used. (100% compatible)

• Higher rigidity

• Improved ATC repeatability, surface finish and higher precision

• Prevents displacement of Z axis in a fast spinning

• Increases the tool life

This holder helps keep productivity and precision at high levels when machining high value curved surfaces or difficult-to-cut materials (high performance parts). Also, as it disperses cutting heat along with chips, the holder helps minimize thermal deformation of workpiece.

Automatic Pallet Changer HP 4000 II / 5100 II are equipped with rotary shuttle  type APC(Automatic Pallet Changer) as a standard feature.It provides high reliability and wide working area for easy setup. 

The possibility that chips might degrade the meshing accuracy of the pallet positioning mechanism increases during APC operation. On the HP 5100 strong jets of air are discharged from the tapered cones when pallets are changed to clean any chips for assuring accurate pallet positioning.

The machine is designed to build rigidity into a stable body. The construction of the machine was thoroughly examined from the stage of basic design to ensure consistent high-speed and high-accuracy operation. The machine is optimized by FEM to prevent the deformation from machining force, axies travel and weight of workpiece.

The axis travel system adopt roller type LM guides that provide high speed axis travel and heavy duty machining.

Axis travel systems are designed for reducing thermal extension by nut cooling and shaft cooling(option) of hall screw. The ball screw id assembled under proper pretension to minimize thermal deformation.
