Price estimate
We do not have a price for the Sugino SC-V30aG 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-V30aG is a vertical grinding center for brittle materials, built on the frame of the maker's #30 vertical machining center. Sugino names silicon, silicon carbide (SiC) and quartz glass as the work it is for. It keeps a tool changer, here with up to 31 BBT30 tools, and adds a C-axis rotary table that turns at up to 200 min-1 under a 20,000 rpm spindle.
That pairing is the point of the machine. A fast spindle with small grinding tools makes small diameter holes, and the rotating table lets a wheel work an outer diameter, so Sugino says both are done with a single chuck on a single machine. A workpiece measurement camera reads marks and sets the workpiece coordinates. A tool measurement system tracks grinding wheel wear and enables automatic truing and dressing.
Travels are 700 mm (27.6 in) in X, 540 mm (21.3 in) in Y and 290 mm (11.4 in) in Z, inside a body 1,440 mm wide. The feed axes are set up for accuracy and not for speed: Sugino switches the ball screw lead from 20mm to 8mm and fits scale feedback on X, Y and Z, and rapid traverse is 24 m/min (945 ipm). On the SC-V30a, the machining center on the same footprint, rapid feed is 60 m/min (2,362 ipm) and Z travel is 400 mm (15.7 in). Repeatability is listed as ±0.001 mm.
Grinding sludge is hard on a machine, and several details answer it. The Y and Z bellows are PVC-coated fabric to keep sludge off the LM guides and ball screws, which also receive a black chrome surface treatment for corrosion resistance. The control is a FANUC 32i-MODEL B Plus. The machine weighs 5,300 kg (11,684 lb) and has a power capacity of 17 kVA. Sugino's table lists no spindle power, table size or positioning accuracy figure.

Strengths & Limitations
Strengths
- 20,000 rpm spindle combined with a C-axis rotary table at up to 200 min-1 for holes and outer diameters in one chucking
- Scale feedback on X, Y and Z and an 8mm lead ball screw for positioning
- Workpiece measurement camera sets workpiece coordinates automatically
- Tool measurement system manages wheel wear and enables automatic truing and dressing
- 700 mm (27.6 in) of X and 540 mm (21.3 in) of Y in a machine 1,440 mm wide
- PVC-coated bellows on Y and Z and surface-treated ball screws and LM guides against sludge
Limitations
- Rapid traverse is 24 m/min (945 ipm), a result of the 8mm ball screw lead
- Z travel is 290 mm (11.4 in)
- Maximum tool dimension is given as φ65, or φ100 with no adjacent tools

Frequently Asked Questions
01
Sugino describes it as a grinding center specialized in various ceramic grinding such as silicon, silicon carbide (SiC) and quartz glass. With a 20,000 rpm spindle and a C-axis rotary table it grinds small diameter holes and outer diameters on brittle materials in a single chucking.
02
Both are 1,440 mm wide with 700 mm (27.6 in) of X and 540 mm (21.3 in) of Y. The SC-V30a is a machining center with 400 mm (15.7 in) of Z, a 12,000 rpm spindle and 60 m/min (2,362 ipm) rapids. The SC-V30aG is the grinding version: 290 mm (11.4 in) of Z, 20,000 rpm, a C-axis rotary table and 24 m/min (945 ipm) rapids on finer-lead ball screws.
03
Sugino lists repeatability of ±0.001 mm. The high-precision specification uses a ball screw lead of 8mm in place of 20mm, and scale feedback devices are installed on the X, Y and Z axes. The maker does not publish a positioning accuracy figure in the table for this model.
04
The CNC device is a FANUC 32i-MODEL B Plus. Tooling is BBT30, with up to 31 tools in the changer. The maximum tool dimension is listed as φ65, or φ100 if there are no adjacent tools; the table prints no unit for that row.
05
Machine dimensions are 1,440 × 3,245 × 2,720 mm (56.7 × 127.8 × 107.1 in) in width, depth and height. Weight is 5,300 kg (11,684 lb) and power capacity is 17 kVA.
