How much does the Johnford SV-41H cost?
Price estimate
We do not have a price for the Johnford SV-41H 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 Johnford SV-41H pairs a geared BT/CAT-50 spindle with 1,050 mm (41.3 in) of X travel. Spindle speed is 60~6,000 rpm and the motor is 11 / 15 kW (14.8 / 20.1 hp) on a Hi-Lo gearbox, the same head Johnford fits to every H model in the SV series.
On this frame the heavy spindle makes more sense than on the shortest one. A 1,200 x 600 mm (47.2 x 23.6 in) table gives room to clamp a casting or a weldment properly and still traverse a large face mill across it. Y and Z travel are 610 mm (24 in) each, and the nose-to-table distance is 100~710 mm (3.94~28 in). Table capacity is 1,200 kg (2,640 lb).
Buyers should look hard at the tool data. 15 kg (33 lb) per tool and 400 mm (15.7 in) of length are generous. Diameter is 125 mm (5 in) in a full magazine and 250 mm (9.8 in) when neighbouring pockets are left empty, which a large face mill or a boring head will require. With only 20 pockets in the standard armless changer, a job that needs several big cutters can run short of positions quickly. The 24 and 32 tool arm type changers on the option list address that.
At 7,500 kg (16,500 lb) the SV-41H is heavier than the 40-taper SV-41 at 7,000 kg (15,400 lb), and at 2,978 mm it stands slightly taller. Its footprint of 2,990 x 3,420 mm is the same.

Strengths & Limitations
Strengths
- Geared 50-taper spindle, 11 / 15 kW (14.8 / 20.1 hp), on a 1,200 x 600 mm (47.2 x 23.6 in) table
- Tool weight up to 15 kg (33 lb) and tool length up to 400 mm (15.7 in)
- Oil cooler for spindle and gearbox is a standard accessory
- Rapids of 30 / 30 / 20 m/min (1,181 / 1,181 / 787 ipm) are the same as on the 40-taper model
Limitations
- 6,000 rpm maximum on the standard spindle limits small-tool work
- 20-tool armless changer as standard; large cutters need adjacent pockets empty
- Table load of 1,200 kg (2,640 lb) is modest for a 50-taper machine
- Z travel of 610 mm (24 in) is shared with the 40-taper model although tools can be 400 mm (15.7 in) long
