Price estimate

Uncertain

We do not have a price for the Chevalier SMART-H/B1224IV 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 Chevalier SMART-H/B1224IV is the 24 in (610 mm) by 12 in (305 mm) model of the SMART-IV CNC surface and profile grinders. It is the first size in the range to carry the 15 hp (11 kW) spindle and the Ø14 in x 2 in x Ø5 in wheel, which makes it a general-purpose machine where the smaller SMART-H/B818IV, with 4 hp (3 kW), is a fine-profile one.

Spindle speed is variable from 500 to 1,800 rpm. With a 14 in wheel that range is about keeping surface speed steady as the wheel wears, and the 2 in (50 mm) width gives enough face for plunge and surface passes as well as dressed forms. The spindle is a cartridge unit on four Class 7 (P4) angular contact ball bearings, which Chevalier rates as suitable for heavy duty grinding.

Table travel is 27.6 in (700 mm) and cross travel 13.8 in (350 mm). The cross-feed ways under the saddle are hand-scraped, Turcite-B coated double V ways that, in the maker's words, support the full table travel and prevent table overhang. Height from table to wheel centerline is 23.6 in (600 mm) and the table takes 815 lb (370 kg).

Two versions share the name. The H table runs at 16 to 82 fpm and the B table at 0 to 65.6 fpm, and the H is much wider on the floor: 158.3 in against 124.4 in for the B, with the same 96.5 in depth. Either way the machine weighs 7,000 lb (3,200 kg).

Strengths & Limitations

Strengths

15 hp (11 kW) spindle on a 24 in (610 mm) by 12 in (305 mm) grinding area
14 in diameter, 2 in (50 mm) wide wheel covers surface, plunge and form passes
Cross-feed double V ways support the full table travel and prevent overhang, per the maker
23.6 in (600 mm) from table to wheel centerline
The B version needs 124.4 in of width where the H needs 158.3 in

Limitations

Top spindle speed is 1,800 rpm, so small wheels cannot reach a useful surface speed
Table load is 815 lb (370 kg)
The H version's table speed starts at 16 fpm; only the B version's range goes down to 0
Cross feed speed tops out at 10 fpm (3,000 mm/min)

Best For

Mould plates, die blocks and fixtures up to 24 in (610 mm) long Mixed surface and profile grinding in a toolroom Form grinding with automatic dressing and compensation Shops moving up from a manual 12 x 24 grinder

Frequently Asked Questions

01 How much larger is the SMART-H/B1224IV than the SMART-H/B818IV?

The SMART-H/B1224IV grinds 24 in (610 mm) by 12 in (305 mm) with a 15 hp (11 kW) spindle and weighs 7,000 lb (3,200 kg). The SMART-H/B818IV grinds 18.1 in (460 mm) by 7.9 in (200 mm) with 4 hp (3 kW) and weighs 3,400 lb (1,550 kg), but its spindle reaches 7,000 rpm against 1,800 rpm here.

02 What table speeds does the SMART-H/B1224IV offer?

The table lists H: 16 to 82 fpm (5 to 25 m/min) and B: 0 to 65.6 fpm (0 to 20 m/min). Cross feed speed is 0 to 10 fpm (0 to 3,000 mm/min) on both. Table travel is 27.6 in (700 mm) and cross travel 13.8 in (350 mm).

03 What wheel does the SMART-H/B1224IV use?

A wheel of Ø14 in x 2 in x Ø5 in (Ø355 x 50 x Ø127 mm), on a spindle variable from 500 to 1,800 rpm. Chevalier lists automatic dressing with compensation during the grinding cycle, so the control accounts for wheel diameter lost to the dresser.

04 How much floor space does it need?

The H version is listed at 158.3 in x 96.5 in x 81.9 in (4,020 x 2,450 x 2,080 mm) and the B version at 124.4 in x 96.5 in x 81.9 in (3,160 x 2,450 x 2,080 mm). Net weight is 7,000 lb (3,200 kg).
