Overview

The Brother SPEEDIO S300X1N is a narrow-body variant of the S300X1 compact high-speed vertical machining center, delivering the same 300 mm X-travel and 5-axis simultaneous machining capability in a reduced-width enclosure for tight production line installations. The N (Narrow) designation indicates an optimized machine body that enables tighter machine-to-machine spacing in production environments where floor space is at a premium.

The S300X1N provides 300 x 300 x 250 mm (11.8 x 11.8 x 9.8 in) X/Y/Z travels with a trunnion-style tilting rotary table (A-axis: -30 to +120 degrees, C-axis: 360 degrees continuous). The 16,000 RPM BT30 spindle, 0.9-second tool-to-tool change, and rapid traverse rates of 60 m/min (2,362 ipm) maintain the full Speedio 5-axis speed advantage. The 22-tool ATC provides ample capacity for complex 5-axis programs.

This is one of the most compact simultaneous 5-axis machining centers available, and the narrow-body option pushes that compactness further. For production cells running small 5-axis components — medical implants, aerospace brackets, watch components, precision instruments — the S300X1N enables 5-axis capability in spaces where even a standard S300X1 might not fit.

The CNC-C00 control provides full 5-axis simultaneous interpolation with RTCP compensation. At $155,000-$210,000 new, the S300X1N serves production environments needing 5-axis capability in the smallest possible footprint. Used units from 2015-2020 trade between $70,000 and $130,000.

Strengths & Limitations

Strengths

Full simultaneous 5-axis capability with RTCP in one of the most compact footprints available
Narrow-body design enables installation in production line positions too narrow for standard 5-axis machines
0.9-second tool-to-tool change and 60 m/min rapids maintain class-leading speed in 5-axis machining
Same travel and 5-axis capability as the standard S300X1 in a reduced-width package
16,000 RPM BT30 spindle excels at high-speed small-part machining in aluminum and non-ferrous alloys
CNC-C00 programming compatibility with all Speedio machines simplifies fleet integration

Limitations

300 mm workpiece diameter and 250 mm Z-travel limit part size to very small components
BT30 taper limits rigidity for aggressive cuts in harder materials like steel and titanium
Narrow enclosure may limit maintenance access for servos, coolant systems, and ATC components
5.5 kW spindle motor restricts material removal rate on harder workpieces

Best For

Medical device manufacturers producing small 5-axis implants and instruments in space-constrained cells Aerospace shops machining small precision brackets and fittings requiring simultaneous 5-axis access Watch and instrument manufacturers needing 5-axis capability in extremely compact installations Production lines adding 5-axis stations within fixed bay widths originally designed for 3-axis machines Multi-machine cells combining narrow-body S300X1N 5-axis stations with S-series 3-axis Speedio machines

Frequently Asked Questions

01 What does the N in S300X1N mean?

N stands for Narrow. The S300X1N has a reduced machine width compared to the standard S300X1 for tighter installation spacing. All machining specifications including 5-axis capability are identical.

02 Is the S300X1N a true simultaneous 5-axis machine?

Yes. The S300X1N supports full simultaneous 5-axis interpolation with RTCP compensation via the trunnion-style A/C rotary table, identical to the standard S300X1.

03 What does a Brother SPEEDIO S300X1N cost?

Brother sells the SPEEDIO range through regional distributors and does not publish list pricing, so the S300X1N is quoted per configuration. On a compact BT30 5-axis machine the price is driven less by the machine than by what surrounds it: through-spindle coolant, probing, chip and coolant management, and pallet or robot loading, which is the whole point of a 0.9-second tool change and 60 m/min rapids. Budget separately for the BT30 holder set and fixturing for the 300 mm rotary. Used SPEEDIO machines are widely traded, and there the variables are spindle hours, control generation and whether the rotary has been crashed.

04 How does the S300X1N compare to the Fanuc Robodrill with 5-axis table?

Both target compact 5-axis small-part production. The S300X1N has a smaller work envelope but purpose-built 5-axis architecture with faster tool changes. The Robodrill offers FANUC control familiarity.
