HK80B CNC Lathe | FANUC 0i-TF Horizontal Lathe – 1265Nm Torque for Shaft, Disk & Ring Parts

CNC System (Optional GSK980TB3i)

• 8.4-inch true-color LCD (Chinese/English)
• Minimum control precision: 0.1 μm
• Max feed speed: 60 m/min
• GSK-Link bus + handwheel trial cut + CS-axis control

The HK80B series is especially well-suited for real workshop jobs such as:

• Roller parts and other shaft parts up to 3000 mm long – transmission shafts, motor shafts, pump shafts, industrial rollers
• Disk and ring parts including flanges, pulleys, gears and bearing housings
• Components requiring steps, external/internal tapers, spheres or threads
• Secondary operations like boring, drilling and tapping in one setup

It is widely used in automotive components, aerospace fittings, energy equipment, general machinery and mold manufacturing. Handles carbon steel, stainless steel, alloy steel, cast iron and engineering plastics efficiently.

For roller machining, the process is straightforward:

1. Install clamping tools and check runout ≤0.02 mm.
2. Mount outer-circle tool and groove tool on the turret (groove tool perpendicularity ≤0.01 mm).
3. Clamp the roller.
4. Adjust tailstock only on first run or when taper appears: take a light cut, measure head-to-tail with micrometer; if difference >±0.03 mm, loosen tailstock and adjust screw by half the difference.
5. Cut again, re-measure and repeat until within ±0.03 mm.
6. Set tool offsets by actual measured diameters.

One HK80B often replaces two or three conventional lathes and saves workshop space in medium-to-large batch roller production.

The HK80B stands out in daily use with these practical benefits:

The bed is high-strength cast iron with a long span and multiple aging treatments. Guideways are medium-frequency quenched, precision-ground and hand-scraped, greatly reducing friction and preventing deformation under heavy cutting forces. Surface finish and accuracy stay excellent for years.

The spindle box uses three manual gears plus stepless regulation, delivering a real 1265 N·m torque and 1120 r/min top speed – stainless and alloy steel cut smoothly without spindle stall.

Tool changing is handled by an electric tool post (4-station vertical standard, 6-station horizontal optional) – fast and stable for mixed batches.

Coolant maintenance is easy thanks to the separate water tank.

With the optional GSK980TB3i system you also get:

• 0.1 μm precision and 60 m/min feed for finer roller surfaces
• GSK-Link bus, handwheel trial cut and CS-axis control for easier complex roller features
• Simple programming and friendly interface that shortens setup time

You can add hydraulic chuck and tailstock so one machine finishes complete shaft, disk and roller jobs in a single setup.

Q1: What is the actual maximum torque?
A: 1265 N·m. This allows heavy cuts on stainless and alloy steel without the spindle stalling.

Q2: What is the longest shaft/roller it can handle?
A: The HK80B-3000 model has 3000 mm between centers and 2810 mm Z travel.

Q3: How does the tool post work?
A: Electric tool post, 4 stations vertical (standard) or 6 stations horizontal (optional) – fast and repeatable.

Q4: Will accuracy drop after long use?
A: Multiple aging on the bed plus scraped guideways resist deformation. Most users see almost no change after 12–18 months.

Q5: What about the optional GSK980TB3i system?
A: It adds GSK-Link bus, handwheel trial cut, CS-axis control, 0.1 μm precision and a user-friendly 8.4-inch color screen – ideal for roller parts requiring high surface finish.

Q6: How do I adjust for taper on rollers?
A: Take a light cut, measure head-to-tail with micrometer. If difference >±0.03 mm, adjust tailstock screw by half the difference and repeat until within tolerance.

Q7: What is the warranty and support?
A: Main parts covered for 12 months; factory provides lifetime technical support and spare parts.
