Overview

The Chevalier Smart B818 III is a compact CNC surface grinder built around a 200 x 450 mm (8 x 18 in) electromagnetic chuck on a 225 x 460 mm (8.9 x 18.1 in) table. It is absent from Chevalier Machinery's current lineup and may be an older model. The listed figures come from a table that has not been confirmed with the maker, so use them to decide whether a used machine deserves a visit and then verify them on the machine.

Travel is listed as 520 mm (20.5 in) longitudinal with automatic feed, 255 mm (10 in) cross and 360 mm (14.2 in) vertical, with a maximum of 400 mm (15.7 in) between spindle and table. The longitudinal stroke overruns the 450 mm chuck length at both ends, which a reciprocating grinder needs in order to reverse clear of the part. Table speed is variable from 5 to 25 m/min, and cross feed per stroke adjusts from 0.1 to 6.0 mm (0.004 to 0.236 in).

The spindle is horizontal and direct-drive, runs at 3,450 RPM and takes a wheel of either 200 mm (8 in) or 250 mm (10 in) diameter. Minimum infeed increment is 0.001 mm (0.00004 in). For precision the table lists surface flatness of ±0.001 mm (±0.00004 in) over 200 mm and a finish of Ra 0.1 µm achievable with fine dressing. On a used grinder both results depend on the state of the ways, the spindle bearings and the dresser.

The control is listed as Chevalier CNC (Smart III), with a control from another maker as an option, so check which one a given machine carries. Chuck magnetic force is given as 850 N/dm². Weight is 1,800 kg (3,968 lb) and the electrical row reads 220/440 VAC 3-phase, 15 A.

Strengths & Limitations

Strengths

200 x 450 mm (8 x 18 in) electromagnetic chuck with a listed magnetic force of 850 N/dm²
Minimum infeed increment of 0.001 mm (0.00004 in) for fine finishing passes
Listed surface flatness of ±0.001 mm (±0.00004 in) over 200 mm
Takes either a 200 mm (8 in) or a 250 mm (10 in) diameter wheel
Table speed variable from 5 to 25 m/min, with cross feed per stroke adjustable from 0.1 to 6.0 mm (0.004 to 0.236 in)

Limitations

Absent from Chevalier Machinery's current lineup; the listed figures are unconfirmed and should be checked on the machine
The table carries two differing rows for spindle power and for wheel width, so read the motor rating from the nameplate and measure the wheel
255 mm (10 in) of cross travel and a chuck 200 mm wide limit the part width ground in one setup
Spindle speed is a single listed 3,450 RPM, with no variable wheel speed shown

Best For

Toolroom grinding of small plates, punches and die inserts on a 200 x 450 mm (8 x 18 in) chuck Finish grinding in 0.001 mm (0.00004 in) infeed increments Fixtures and parts within the 400 mm (15.7 in) spindle-to-table distance Small toolrooms: 1,800 kg (3,968 lb) and a 15 A supply at 220/440 VAC 3-phase

Frequently Asked Questions

01 What chuck and table size does the Smart B818 III have?

The electromagnetic chuck is listed at 200 x 450 mm (8 x 18 in) and the table at 225 x 460 mm (8.9 x 18.1 in). Chuck magnetic force is given as 850 N/dm². These are listed figures that have not been confirmed with the maker.

02 What are the travels of the Chevalier Smart B818 III?

Longitudinal travel is 520 mm (20.5 in) with automatic feed, cross travel is 255 mm (10 in) and vertical travel is 360 mm (14.2 in). The maximum distance from spindle to table is 400 mm (15.7 in).

03 What grinding wheel does the Smart B818 III take?

The wheel size row lists two diameters, 200 mm (8 in) or 250 mm (10 in), on a horizontal direct-drive spindle running at 3,450 RPM. The table gives two different wheel widths in separate rows, so measure the wheel and flange on the machine before ordering wheels.

04 Which control is fitted to the Smart B818 III?

The control row lists Chevalier CNC (Smart III), with a control from another maker as an option. A used machine could carry either, and programming, spares and support differ between them, so identify the control before agreeing a purchase.

05 Is the Smart B818 III a current Chevalier model?

It does not appear in Chevalier Machinery's current lineup and may be an older model. Treat the listed figures as unconfirmed and check travel, chuck size, 1,800 kg (3,968 lb) weight and the 220/440 VAC 3-phase, 15 A supply against the machine's own documents.
