How much does the Enshu BH100VL cost?
Estimated price range
Our best estimate for a vertical machining centers (vmc) in this class — not a quote from Enshu. Configuration moves it a long way.
Overview
The Enshu BH100VL is a vertical machining center with an integrated honing function. The listed figures describe a BT-40 machine with a 12,000 RPM, 15 kW (20 hp) spindle whose Z axis is driven by a high-powered linear motor, so that bores can be honed in the setup in which they were machined. Enshu's current product pages do not show this model, and the figures should be confirmed against the documentation of the actual machine.
The linear motor is what makes the honing possible. Honing needs the tool to stroke up and down the bore quickly and to reverse cleanly at each end, a motion a linear motor handles more readily than a ballscrew. Combining it with milling and boring removes the transfer to a separate honing machine, and with it the re-clamping error between boring and honing.
As a machining center the listed envelope is 800 mm (31.5 in) in X, 600 mm (23.6 in) in Y and 500 mm (19.7 in) in Z, with a maximum workpiece weight of 500 kg (1,102 lb). Rapid traverse is 60 m/min (2,362 ipm) in X and Y. The magazine holds 30 tools and through-spindle coolant is listed as standard at 70 bar (1,015 psi). The control is listed as Fanuc 31i-B5.
Machine weight is approximately 10,000 kg (22,046 lb). The listed figures give no honing stroke rate, bore diameter range or achievable bore finish, and those are the first questions for anyone evaluating a BH100VL for a specific bore.

Strengths & Limitations
Strengths
- Integrated CNC honing with a linear motor Z axis, so bores are machined and honed in one setup
- BT-40 spindle listed at 12,000 RPM and 15 kW (20 hp)
- Through-spindle coolant listed as standard at 70 bar (1,015 psi)
- Listed travels of 800 mm (31.5 in), 600 mm (23.6 in) and 500 mm (19.7 in) in X, Y and Z
- 30-tool magazine in the listed specification
Limitations
- No honing stroke rate, bore size range or finish figures are listed
- Maximum workpiece weight is 500 kg (1,102 lb), fixture included
- Approx. 10,000 kg (22,046 lb) of machine weight needs rigging and floor planning
- Not shown on Enshu's current product pages; confirm figures against the machine's own documentation

Frequently Asked Questions
01
Honing. The machine type is listed as a vertical machining center with integrated honing function, and the Z axis is driven by a high-powered linear motor. That lets one machine mill, bore and then hone a bore without moving the part to a separate honing machine.
02
800 mm (31.5 in) in X, 600 mm (23.6 in) in Y and 500 mm (19.7 in) in Z, with a maximum workpiece weight of 500 kg (1,102 lb). Rapid traverse is listed as 60 m/min (2,362 ipm) for X and Y, with the Z axis on its linear motor.
03
The listed spindle is BT-40 with 12,000 RPM and 15 kW (20 hp). The magazine holds 30 tools, and through-spindle coolant at 70 bar (1,015 psi) is listed as standard. The control is listed as Fanuc 31i-B5.
04
The listed figures say nothing about honing stroke speed, the bore diameters the honing function covers or the finish and geometry it holds. Ask for those, and for a test on a representative bore. Since the model is not on Enshu's current product pages, also confirm the fitted spindle, coolant system and control on the actual machine.
