How much does the Onsrud F148CH cost?
Price estimate
We do not have a price for the Onsrud F148CH 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 Onsrud F148CH is the base model of the CH-Series, a fully enclosed compact high-rail mill. The table is 84 in (2,134 mm) by 142 in (3,607 mm), the Z-stroke is 52 in (1,321 mm), and the standard spindle is 33 hp (24.6 kW) at 24,000 rpm. Onsrud lists the series among its 5-axis mills.
High-rail means the bridge runs on rails set on raised walls, so the table itself stays fixed and can carry very heavy work. Onsrud designs the series for the extreme weights of large nonferrous or light ferrous metal and advanced composite block and plate. Dual ball-screw drives move the bridge, and a stiff Z-ram is used to limit spindle twist and deflection at tall working heights.
This is not a small machine: 211 in (5,360 mm) long, 278 in (7,062 mm) wide and 198 in (5,030 mm) high, with heavy-gauge steel walls and a full enclosure.
Fifteen tools are standard and capacities of 36-120+ are optional. For hard cutting there is a 75 hp (55.9 kW) spindle that runs to 18,000 rpm. The table has 1 vacuum zone, though work of this weight is more often bolted down. Laser compensation, linear scales and part probing are recommended by the maker for tight tolerances.

Frequently Asked Questions
01
The table is 84 in (2,134 mm) in X by 142 in (3,607 mm) in Y, and the Z-stroke is 52 in (1,321 mm). The F148CH W10 widens table X to 120 in (3,048 mm).
02
A 33 hp (24.6 kW) spindle at 24,000 rpm is standard. The upgrade is a 75 hp (55.9 kW) spindle with a top speed of 18,000 rpm, the choice for heavier cuts in metal.
03
15 as standard. Onsrud lists tool capacities of 36-120+ and a second tool changer as upgrades, which suits long unattended programs on large parts.
04
Yes. Onsrud describes the CH-Series as a fully enclosed CNC machining center with a steel frame base, internal steel reinforcements and heavy-gauge steel walls.
