New machine offers advantages of an HMC and boring mill
- August 9, 2017
Mazak Corp.'s new HCN-16000Q horizontal machining centre, recently installed in the company's North American plant in Florence, KY, to help the company ramp up production, features a double column, quill-head design to allow the machine to perform operations of an HMC and a boring mill.
As the first in Mazak’s series of HCNs with quills, the HCN-16000Q is available in single table (open or covered) and two-pallet machine configurations. It is well suited for part production in the oil and gas industry, construction equipment, mining and farm equipment or any part production in which customers want the speed and accuracy of a Mazak horizontal machine plus the quill for long reach milling and boring operations.
For stability, reliability and accuracy, the HCN-16000Q’s double column design centers the quill head to eliminate potential problems resulting from overhang or imbalance, which are typically associated with traditional boring machines. Mazak’s double column also features a twin ballscrew-driven Y axis that eliminates the need for any type of counterbalance mechanism. This ensures fast, precise and smooth Y axis stroke extension and retraction, says the company.
The Mazak quill features a built-in motor, high torque, direct drive, 50 hp (37 kW) spindle that puts out 1,000 ft/lbs (1,357 Nm) of torque. Mazak equips the quill with linear drive guides as well as both angular contact and roller-type bearings. Roller bearings in the front of the spindle provide stability against strong side forces from face milling or heavy roughing, while the angular contact bearings in the back support the quill’s Z axis thrust for heavy duty boring and drilling operations.
Standard tool capacity of the HCN-16000Q is 80 tools with options to increase that to 120 or 160 or incorporate Mazak’s ToolTech system. Also available is a tool changing system specifically for handling larger sized tools. The changer mounts to the machine’s pallet changer and quickly moves larger size tools in and out of the machine to speed exchanges and reduce non-cut times. Mazak also offers the machining center with an automatic attachment changer that further boosts part processing flexibility through the use of various special operation attachments such as angled heads, U-axis boring tools and facing heads, U axis OD turning heads and snout heads.
The HCN-16000Q’s 1,250 mm x 1,600 mm (49.2 x 63.0 in.) pallets accommodate workpieces up to 3,000 mm (118.11 in.) in diameter, 2,000 mm (78.74 in.) high and weighing as much as 8,000 kg (17,636 lb) (two-PC model) and 10,000 kg (22,046 lb) (single table model). Machine axis travels measure 2,800 mm (110.236 in.) in X, 1,600 mm (63 in) in Y, and 1,850 mm (72.834 in.) in Z, while the quill W axis feed stroke is 550 mm (21.653 in.).
The new machine can be added to existing manufacturing cells, including those with dissimilar machines such as the Mazak e-Vertical and Integrex series of machines. When the machine is part of an automated Mazak Palletech cell, it further increases the cell’s overall versatility with the company's Done-in-One processing with the addition of deep boring and U axis machining capabilities.
