Horizontal machining centres with 800 mm pallet size, gear spindle and box guideways on all axes
Stable and high-power roughing - precise and dynamic smoothing! The H6 is the optimal solution if high rigidity is required for the machining of your workpieces. The generously proportioned box guideways and the twin drives on the X and Y axes permit accuracy and high cutting rates. The charging of the box guideways with compressed air results in a very low break loose torque and guarantees uniformity of movement. The high drive torque on the gear spindle and the unique Hwacheon oil jet cooling system provide stable high performance cutting and the highest quality machining, even over longer machining times. The zero backlash pre-loaded worm drive on the B axis, combined with a rotary encoder which regulates directly, guarantee that your requirements for accuracy will be met. The solid and extremely stiff structure of the machine bed and machine stand - designed and sized by means of FEM - is an additional factor contributing to the high machining quality of finished workpieces. Combined with the exclusive Hwacheon software components, you will simultaneously achieve greater efficiency, higher productivity and process safety.
Product Description
Highlights
- All axes with box guideways
- Hwacheon spindles:
- Gear spindle: 8,000 rpm (35/22 kW and 1654 Nm)
- Motor spindle: 12,000 rpm (30/25 kW and 420 Nm)
Robust, rigid machine structure
The solid machine bed supports the feed drives with the highest levels of rigidity and the thermo-symmetrical construction maintains geometric precision.
High precision twin drive
High precision twin drives on the X an Y axes minimise the yaw torque during translational motion.
Gear spindle
The 2-speed, spindle drive with automatic transmission provides high-torque cutting performance at low speeds and excellent performance at high speeds.
Oil cooling
Oil flow cooling and casing cooling in the spindle have been perfected as a result of Hwacheon’s know-how in the area of spindle construction.
