Overview

The Mazak HCN-Q series is purpose-built for deep boring and heavy-duty machining of large workpieces weighing up to 10,000 kg (22,046 lb). Available in three sizes (HCN-12500Q, HCN-16000Q, HCN-16800Q), each with single-pallet QS variants, these machines feature quill-type spindles designed specifically for deep-hole boring operations that conventional HMC spindles cannot reach.

The quill spindle runs at up to 3,000 RPM through a CAT 50 taper with 45 kW (60 hp) at 40% ED and a massive 1,849 Nm (1,363 ft-lb) of torque. The quill diameter measures 130 mm (5.12 in) with a bearing inside diameter of 180 mm (7.09 in), giving the spindle the rigidity to handle deep boring without chatter. This torque-to-speed ratio is specifically optimized for ferrous materials and deep-cavity work.

Pallet sizes range from 1,250 x 1,000 mm (49.2 x 39.4 in) on the HCN-12500Q to 1,600 x 1,250 mm (63.0 x 49.2 in) on the HCN-16000Q and HCN-16800Q. The largest model handles workpieces up to 3,000 mm (118.1 in) diameter and 2,400 mm (94.5 in) height. Axis travels scale accordingly, with the HCN-16800Q offering over 2,000 mm of Z-axis stroke for reaching deep into large castings.

These machines are built for industries that work with large castings, weldments, and fabricated structures: power generation turbine housings, oil and gas valve bodies, heavy equipment frames, and large mold bases. New HCN-Q machines price from $900,000 to $1,800,000+ depending on model and options. They compete with large horizontal boring mills from Toshiba, Kuraki, and SNK.

Strengths & Limitations

Strengths

Quill-type spindle with 1,849 Nm of torque at 3,000 RPM is specifically designed for deep boring operations that conventional HMC spindles cannot handle
10,000 kg table load capacity accommodates the largest castings and weldments found in power generation, oil and gas, and heavy equipment
Three size options from 1,250mm to 1,600mm pallets cover a wide range of large-part applications with the same platform architecture
Two-pallet and single-pallet (QS) variants available, with the QS models saving floor space in shops that do not need pallet change automation
Workpiece capacity up to 3,000 mm diameter and 2,400 mm height rivals floor-type horizontal boring mills in a more compact footprint
130 mm quill bore with 180 mm bearing diameter maintains rigidity during deep boring, minimizing chatter and improving surface finish

Limitations

3,000 RPM maximum spindle speed limits this machine to ferrous materials and heavy-duty work; not suitable for aluminum or high-speed applications
Starting price above $900,000 makes this a substantial capital investment that requires consistent large-part volume to justify
20 m/min rapid traverse is slow, adding significant non-cutting time on positioning moves across the large work envelope
The sheer size and weight of these machines requires dedicated floor space, heavy-duty foundations, and overhead crane access for workpiece loading

Best For

Frequently Asked Questions

01 What does a Mazak HCN-Q cost?

New HCN-Q machines start around $900,000 for a base HCN-12500Q and can exceed $1,800,000 for a fully equipped HCN-16800Q with expanded tool magazine, high-pressure coolant, and probing packages. Single-pallet QS variants are typically 10-15% less than their two-pallet counterparts.

02 What is the quill spindle and why does it matter?

The quill spindle extends and retracts like a boring mill quill, allowing the tool to reach deep into cavities without moving the entire spindle head. The 130 mm diameter quill provides the rigidity needed for precision boring at depth. This design is critical for deep-hole work in large castings that would cause conventional Z-axis ram-type spindles to deflect.

03 How does the HCN-Q compare to a floor-type horizontal boring mill?

The HCN-Q offers faster cycle times through automatic pallet changing, faster tool changing (up to 120 tools), and higher positioning accuracy than most floor-type boring mills. The boring mill wins on maximum part size and reach. For parts within the HCN-Q work envelope, it is significantly more productive.

04 Can the HCN-Q handle automated production?

Yes. The two-pallet models allow loading one pallet while the other cuts. For parts within the weight and size limits, the HCN-Q runs unattended with tool life management and probing cycles. However, the typical workpiece size and weight means crane loading is required, which usually needs operator presence.
