Overview
The Haas SR-4020 is the largest sheet router in the Haas lineup, offering a massive 4,064 x 2,032 x 152 mm (160 x 80 x 6 in) cutting envelope that handles sheet stock up to 8 feet wide and over 13 feet long. If you need to process oversize aluminum panels, composite sheets, or large-format plastic stock on a single machine, the SR-4020 eliminates the need for repositioning or multiple setups.
The spindle is the same 22.4 kW (30 hp) inline direct-drive unit running to 15,000 RPM with a CT/BT 40 taper used across the SR series. The torque output of 122 Nm (90 ft-lbf) gives the machine real cutting authority — this is not a lightweight router spindle, but a production mill spindle mounted on a gantry platform. Liquid cooling keeps the spindle thermally stable during extended production runs.
Rapids run at 30.5 m/min (1,200 ipm) on X and Y, which is critical on a machine with 13+ feet of X travel. Slow rapids on a machine this large would cripple cycle times. The 30+1 SMTC provides generous tool capacity with 1.6-second tool-to-tool changes. The T-slot table measures approximately 4,115 x 2,032 mm (162 x 80 in) with a 2,268 kg (5,000 lb) load capacity.
At roughly 11,340 kg (25,000 lb), the SR-4020 is a substantial machine that requires dedicated floor space and rigging. The Z-axis travel is intentionally limited to 152 mm (6 in) — this is a sheet-processing machine optimized for through-cutting, pocketing, and profiling in sheet stock, not a deep-cavity mill.
The NGC control runs the same G-code and conversational programming as every Haas. For aerospace, marine, architectural, and transportation industries processing large-format sheet materials, the SR-4020 delivers CNC precision at router-class productivity.

Strengths & Limitations
Strengths
- 160x80-inch cutting envelope handles oversize sheet stock that exceeds the SR-3015's 5x10-foot capacity
- 30 HP 15,000 RPM inline direct-drive spindle provides production mill-grade cutting authority on a router platform
- 1,200 ipm rapids minimize non-cutting time across the machine's 13+ feet of X travel
- 5,000 lb table load capacity supports heavy sheet stock and robust fixturing across the full table
- 30+1 SMTC with 1.6-second tool-to-tool enables complex multi-tool nesting programs
- Same NGC control and programming environment as all Haas machines
Limitations
- Very large footprint requires dedicated floor space and careful facility planning
- 6 inches of Z travel limits work to sheet-thickness applications
- 25,000 lb machine weight requires reinforced floor and heavy rigging for installation
- Higher base price than the SR-3015 may not be justified if 5x10-foot sheets are the maximum requirement

Frequently Asked Questions
01
Base price starts around $185,000. With through-spindle coolant, probing, and production options, expect $210,000-$240,000. The P (pallet) variant adds approximately $25,000-$35,000.
02
The SR-4020 adds 1,016 mm (40 in) of X travel and 508 mm (20 in) of Y travel, increasing the cutting envelope from 5x10 feet to over 8x13 feet. Spindle, rapids, and tool changer are identical. Choose based on your maximum sheet size requirement.
03
Yes. The SR-4020 handles carbon fiber, fiberglass, phenolic, and other composite sheet materials. The 15,000 RPM spindle and high rapids support the high-speed, light-depth-of-cut strategies that composites require. Dust collection and proper ventilation are essential for composite work.
04
Primarily aluminum sheet, composite panels, plastics, and non-ferrous materials. The 6-inch Z travel and sheet router architecture are optimized for through-cutting and profiling rather than deep pocketing. It can cut mild steel sheet but is not designed for heavy ferrous work.
