Overview
The Haas VF-4 stretches X-travel to 1,270 mm (50 in), making it the largest standard VF-series mill. It shares the same 22.4 kW (30 hp) inline direct-drive spindle as the VF-2 and VF-3, but that extra 10 inches over the VF-3 opens up long-part work, multi-vise setups, and tombstone fixtures that simply won't fit on a 40-inch table.
Table dimensions are 1,321 x 495 mm (52 x 19.5 in) with five T-slots on 80 mm centers. Load capacity hits 1,588 kg (3,500 lb) evenly distributed, so heavy steel fixtures, rotary tables, and fourth-axis setups aren't a problem. Spindle-nose-to-table range runs from 107 mm (4.2 in) to 742 mm (29.2 in), giving you clearance for tall workholding without sacrificing Z reach.
The spindle tops out at 8,100 RPM with 122 Nm (90 ft-lb) of torque at 2,000 RPM. Taper options include CT40, BT40, and HSK-A63. An optional two-speed gearbox pushes torque to 339 Nm (250 ft-lb) at 450 RPM for heavy hogging in steel and cast iron. For shops cutting mostly aluminum, the VF-4SS variant bumps to 12,000 RPM with faster rapids and a side-mount tool changer.
The standard 20-station carousel delivers 4.2-second tool-to-tool and 4.5-second chip-to-chip times. Haas now offers 50+1 and 70+1 side-mount upgrades for production cells that need more tool stations. Rapids run at 25.4 m/min (1,000 ipm) on all three axes, and max cutting feedrate is 16.5 m/min (650 ipm). Axis thrust peaks at 11,343 N (2,550 lbf) on X and Y, with the Z axis pushing 18,683 N (4,200 lbf).
Positioning accuracy is ±0.0051 mm (±0.0002 in) with repeatability at ±0.0025 mm (±0.0001 in), consistent across the VF family. The NGC control with its 15-inch color LCD, 1 GB program memory, USB, and Ethernet connectivity is the same interface your operators already know from other Haas machines.
Base shipping weight is 5,316 kg (11,720 lb), rising to 6,260 kg (13,800 lb) with a chip conveyor and SMTC. The VF-4 competes directly with the Okuma GENOS M560-V and Mazak VCN-530C on work envelope, though it's priced well below both. Base price runs $65,000-$70,000 new. Used VF-4s from 2010-2020 typically sell for $20,000-$40,000 depending on hours and condition. Specs sourced from Haas Automation published product data.

Strengths & Limitations
Strengths
- 1,270 mm (50 in) X-travel is the largest in the standard VF series, handling long parts and multi-vise setups that won't fit on the VF-2 or VF-3
- 1,588 kg (3,500 lb) table load on a 1,321 x 495 mm (52 x 19.5 in) table supports heavy steel fixtures, rotary tables, and tombstone setups
- Base price around $65K-$70K undercuts the Okuma GENOS M560-V and Mazak VCN-530C by a wide margin for comparable X-travel
- CT40, BT40, and HSK-A63 taper options give you flexibility to match tooling standards across your shop
- Optional two-speed gearbox delivers 339 Nm (250 ft-lb) at 450 RPM for serious material removal in steel and cast iron
- Same NGC control and spindle architecture as every other VF machine means zero retraining when operators move between machines
- Strong used market with 2010-2020 machines available for $20K-$40K, plus fast parts availability through the Haas Factory Outlet network
Limitations
- 8,100 RPM standard spindle limits high-speed aluminum work; the VF-4SS (12K RPM) adds significant cost to the base price
- 20-station carousel with 4.5-second chip-to-chip is slow compared to arm-type changers on competing Okuma and Mazak VMCs
- 25.4 m/min (1,000 ipm) rapids trail the 36+ m/min offered by linear-guide competitors from Mazak and Okuma
- Longer 50-inch X-axis travel introduces more potential deflection at full extension compared to the shorter VF-2 and VF-3
- Forum reports suggest some VF-series controls from 2019 onward have had reliability issues, though Haas service response remains fast

Frequently Asked Questions
01
Base price has held steady around $65,000-$70,000 for several years. Most shops add through-spindle coolant, probing, a chip conveyor, and possibly an SMTC upgrade, bringing the total to $80,000-$100,000 depending on options. Used VF-4s in good condition sell for $20,000-$40,000 depending on year and spindle hours.
02
The VF-4SS bumps spindle speed to 12,000 RPM (vs 8,100), adds faster rapids, and swaps the carousel for a high-speed side-mount tool changer. If your shop cuts 50%+ aluminum or runs high-speed toolpaths, the SS pays for itself in cycle time savings. For steel-dominant work, the standard VF-4 is the better value. Forum discussions comparing 2014 vs 2017 VF4SS models note that the 30 hp / 12K spindle has enough torque for most steel operations.
03
It comes down to part size and fixturing. The VF-4 adds 10 inches of X-travel (50 vs 40 in) and a slightly longer table (52 vs 48 in). If your typical parts fit within 40 inches and you don't need multi-vise setups, the VF-3 saves money and floor space. The VF-4 makes sense when you're regularly running parts or fixtures that need that extra envelope.
04
Yes, and it's one of the most popular platforms for 4th-axis work. The 52-inch table gives you room for a rotary table plus workholding. Many VF-4s come factory pre-wired for 4th axis. If buying used, confirm the machine has the 4th-axis drive option and check whether it uses brushed or brushless motors. Forum threads on Practical Machinist report that older brushed-motor 4th-axis setups can overheat at idle, so verify the motor type before buying.
05
The VF-4 shares the same drivetrain and control as the entire VF series. Common maintenance items include spindle bearings (typically 8,000-12,000 hours), way wipers, linear guide replacement, and coolant system upkeep. Haas Factory Outlet service response is usually same-day. Older pre-2007 models can have outdated controls that are expensive to upgrade. Some forum users report increased control issues on 2019+ models, though opinions vary.
06
The VF-4 runs on 220 VAC 3-phase at 70 amps full load, with an optional 440 VAC transformer (35 A) available factory-installed only. Air supply calls for 113 L/min at 6.9 bar (4 SCFM at 100 PSI) minimum, though actual consumption depends on tool change frequency and pneumatic accessories. Minimum air pressure is 5.5 bar (80 PSI).
