Overview
The Haas VF-4YT is the extended Y-axis variant of the VF-4, pushing Y-axis travel from 457 mm (18 in) to 508 mm (20 in). Combined with 1,270 mm (50 in) of X-travel and 635 mm (25 in) of Z-travel, the VF-4YT covers parts that need a wider working envelope without jumping to the VF-5 or VF-6 platforms.
The spindle delivers 22.4 kW (30 hp) with speeds up to 8,100 RPM standard or an optional 12,000 RPM upgrade. The CAT 40 taper is standard across the VF lineup. The table measures 1,321 x 457 mm (52 x 18 in) with a 1,588 kg (3,500 lb) load capacity — enough for moderate fixture plates and tombstones.
The 20+1 side-mount tool changer handles standard tooling. Rapids run at 25.4 m/min (1,000 in/min) on all axes. Machine weight is approximately 4,536 kg (10,000 lb), giving the VF-4YT more mass and rigidity than the smaller VF-2 platform.
The NGC control is the same across the Haas lineup. Programmers and operators moving between Haas machines don't skip a beat.
At $80,000-$110,000 configured, the VF-4YT is positioned for shops that work on mid-sized plates, mold bases, and fixtures where the extra 50 mm of Y-axis travel keeps parts in the envelope without creative fixturing. It's a targeted solution for the shop that finds the VF-4 just barely too small in Y.

Strengths & Limitations
Strengths
- 508 mm (20 in) Y-axis travel covers wider parts that push the standard VF-4 to its limit
- 1,270 mm (50 in) X-travel handles long plates and multi-part fixturing in a single setup
- 22.4 kW (30 hp) spindle is competitive for the frame size and price point
- 1,588 kg table load supports moderate tombstones and fixture plates
- Smaller footprint than the VF-5 while delivering comparable Y-axis reach
- NGC control with consistent interface across the Haas lineup
Limitations
- Only 50 mm more Y-axis than the standard VF-4 — marginal for some shops
- 8,100 RPM standard spindle limits high-speed aluminum machining
- 20-pocket tool changer can be restrictive for complex jobs requiring many tools
- CAT 40 taper limits heavy cutting capability compared to 50-taper machines
- Table width unchanged from VF-4 despite the Y-axis extension

Frequently Asked Questions
01
The VF-4YT extends Y-axis travel from 457 mm (18 in) to 508 mm (20 in). X-axis, Z-axis, spindle, table, and tool changer are identical. The YT variant is designed for shops that regularly bump into the VF-4's Y-axis limit on plates and mold work.
02
Base price is around $80,000. With through-spindle coolant, probing, 4th-axis drive, and chip management, expect $95,000-$110,000 configured. The premium over a standard VF-4 is roughly $3,000-$5,000.
03
The VF-5 offers 660 mm (26 in) of Y-travel and a 1,321 x 559 mm table — significantly more than the VF-4YT's 508 mm Y-axis. If you need substantially more Y-travel, the VF-5 is the better investment. The VF-4YT is for shops that only need a modest Y-axis bump over the VF-4.
04
Yes. The 1,588 kg table load capacity and 1,270 mm X-travel support moderate tombstone setups. For a 4th-axis tombstone, add the 4th-axis drive option. Keep in mind the 20-pocket tool changer may limit how many operations you can run per setup.
