Price estimate
We do not have a price for the Sugino SC-H30a that we can stand behind, so we show no number. Configuration, options and installation move the final price a long way: a quote is the reliable figure.
Overview
The Sugino SC-H30a is a #30 horizontal machining center built around one unusual choice: the Z axis moves the table, not the spindle. X and Y are column traverse over 500 mm (19.7 in) and 400 mm (15.7 in), and the table feeds the work toward a stationary main spindle over 500 mm (19.7 in). Sugino's reason is deep holes. With the spindle not travelling in Z, the maker says high straightness is achieved even in deep hole machining.
The tool limits are set to match. Standard maximum tool length is 250 mm (9.8 in), with options for 350 mm (13.8 in) and 450 mm (17.7 in), long for a BBT30 machine. Diameter is φ60 mm beside another tool and φ120 mm with the adjacent pockets empty, and weight is 2.0 kg, or 3.5 kg at low-speed ATC.
The second theme is running unattended. The magazine holds 29 tools as standard and 71 as an option. Sugino's argument for the large magazine is spare tools: duplicates can be set up so that worn tools are replaced on schedule, which keeps burr size under control and the line running. The maker also separates the machine room from the processing room, keeps wiring and piping out of the workspace, and uses a center trough bed so chips fall straight down and out.
Performance figures are those of a fast 30-taper machine: 12,000 rpm, 0.16 sec to reach 10,000 rpm, 60 m/min (2,362 ipm) rapids and 1.5 G on all three axes. Tool to tool time is 2.2 sec, and tapping runs at up to 8,000 rpm. The maker's table for this model lists no spindle power, table size or table load, so those need to be asked for. Weight is 4,700 kg (10,362 lb).

Strengths & Limitations
Strengths
- Z-axis table traverse over 500 mm (19.7 in) with a stationary spindle, which Sugino credits for straightness in deep holes
- Tool length up to 450 mm as an option, 250 mm as standard
- Magazine of 29 tools, expandable to 71 for spare-tool strategies
- 60 m/min (2,362 ipm) rapids and 1.5 G acceleration on X, Y and Z
- Spindle reaches 10,000 rpm in 0.16 sec, with a 12,000 rpm maximum
- Machine room and processing room are completely separated, with a center trough bed for chips
Limitations
- Tools are limited to 2.0 kg, or 3.5 kg at low-speed ATC
- Tool to tool time of 2.2 sec is slow next to the rapid and spindle acceleration figures
- The 350 mm and 450 mm tool lengths and the 71-tool magazine are options
- The specification table gives no spindle power, table size or allowable load

Frequently Asked Questions
01
So that the main spindle stays stationary while the work feeds onto the tool. Sugino says this Z-axis table traverse, with a stroke of 500 mm (19.7 in), gives high straightness even in deep hole machining. X and Y, at 500 mm (19.7 in) and 400 mm (15.7 in), are column traverse.
02
Maximum tool length is 250 mm (9.8 in) as standard, with 350 mm (13.8 in) and 450 mm (17.7 in) available as options. Maximum diameter is φ60 mm with an adjacent tool and φ120 mm with no adjacent tool. Maximum weight is 2.0 kg, or 3.5 kg at low-speed ATC.
03
It holds 29 tools as standard and 71 as an option, with memory random selection and a tool to tool time of 2.2 sec. Sugino presents the 71-tool magazine as a way to cut changeover time, set up spare tools for long continuous operation, and replace worn tools in time to control burrs.
04
Maximum spindle speed is 12,000 rpm as standard, and acceleration to 10,000 rpm takes 0.16 sec. Rapid feed is 60 m/min (2,362 ipm) on X, Y and Z with 1.5 G of acceleration and deceleration. Cutting feed goes up to 30 m/min and maximum tap rotation speed is 8,000 rpm.
05
The body is 1,500 mm wide, plus 380 mm for the operation panel, 3,210 mm long and 2,280 mm high. It weighs 4,700 kg (10,362 lb). By comparison the SC-H40 is 1,440 mm wide and weighs 6,300 kg (13,889 lb).
