How much does the Weldon Solaris cost?
Price estimate
We do not have a price for the Weldon Solaris 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
With 60 in (1,524 mm) between centers and 74 in (1,880 mm) of worktable travel, the Weldon Solaris is a CNC cylindrical grinder built for long shafts. Swing is 16 in (406 mm) as standard, and 22 in (559 mm) can be had as an option.
Long strokes are where the drive matters most, and the Z axis here uses a FANUC linear motor, so there is no long screw in the drive to sag, heat or stretch. Command resolution is 0.000010 in, with position feedback resolved ten times finer at 0.0000010 in.
Grinding power is in proportion to the bed. A 25 hp (18.6 kW) T.E.F.C. motor turns a wheel 24 in (610 mm) in diameter and 5.0 in (127 mm) wide at a nominal 8,500 SFPM. The Altaira carries the same 25 hp (18.6 kW) rating and the same listed weight of 22,000 lb (9,979 kg), and both run the FANUC 0i-TF control. The G300, by contrast, has 10 hp (7.5 kW) at the wheel.
The standard workhead is a 5.0 hp (3.7 kW) FANUC AC servo unit running 0-900 rpm, with a 6 in A2 (ASME) nose, a #5 Morse center and a 1.0625 in (27 mm) through hole. Weldon also lists an optional programmable workhead with a rotary scale. A scale on the work spindle lets the control know the angular position of the part, which is what work with features tied to rotation needs. The trade is speed: the programmable workhead is limited to 475 rpm max.
Plan for a big footprint, 151 x 150 x 91 in (3,835 x 3,810 x 2,311 mm) (W x D x H), with 480 V, 3-phase, 60 Hz power and 5 SCFM of air at 80 psi. The tailstock quill retracts 3 in (76 mm) by manual lever. Two things a long-shaft buyer will want are missing from the table: a maximum workpiece weight and any mention of work supports along the bed. Ask for both.

Strengths & Limitations
Strengths
- 60 in (1,524 mm) between centers and 74 in (1,880 mm) of worktable travel for long shafts
- FANUC linear motor on the Z axis, so the long stroke has no screw in the drive
- Optional programmable workhead with a rotary scale for work that needs the part's angular position controlled
- 25 hp (18.6 kW) wheel motor with a 24 in (610 mm) dia x 5.0 in (127 mm) wide wheel
- Optional 22 in (559 mm) swing over the standard 16 in (406 mm)
- Position feedback resolution of 0.0000010 in
Limitations
- Takes 151 x 150 in (3,835 x 3,810 mm) of floor and weighs 22,000 lb (9,979 kg)
- The programmable workhead is an option and tops out at 475 rpm, against 900 rpm for the standard workhead
- The tailstock quill is retracted 3 in (76 mm) by manual lever, a hand operation on what may be heavy shafts
- No maximum workpiece weight and no wheel slide travel are listed
- Needs a 480 V, 3-phase supply

Frequently Asked Questions
01
Up to 60 in (1,524 mm) between centers, with 74 in (1,880 mm) of worktable travel. Maximum work swing is 16 in (406 mm), or 22 in (559 mm) with the optional swing. The table lists no maximum workpiece weight, so confirm that for heavy shafts.
02
It is listed as a programmable workhead with a rotary scale and a maximum speed of 475 rpm. The standard workhead is a 5.0 hp (3.7 kW) FANUC AC servo unit running 0-900 rpm. Choosing the option gives up top speed in exchange for measured rotary position.
03
On the figures both share, they match: a 25 hp (18.6 kW) T.E.F.C. wheel motor, a listed weight of 22,000 lb (9,979 kg) and the FANUC 0i-TF control. The Solaris is the one to look at when the part needs 60 in (1,524 mm) between centers.
04
Command resolution is 0.000010 in and position feedback resolution is 0.0000010 in. The Z axis is driven by a FANUC linear motor, and the table drive motors are listed as 1.9 hp (1.4 kW) FANUC AC digital servos. These are resolution figures; the table does not state a positioning accuracy.
05
The machine is 151 x 150 x 91 in (3,835 x 3,810 x 2,311 mm) (W x D x H) and weighs 22,000 lb (9,979 kg) on a welded steel Shear Damper base. It needs 480 V, 3-phase, 60 Hz power and 5 SCFM of air at 80 psi. Allow room at the ends for loading long shafts.
