Overview

The Bourn & Koch Blanchard 22AD-42 is a vertical-spindle rotary surface grinder with a 42 in (1,067 mm) magnetic chuck, a 22 in (559 mm) grinding wheel and 48 in (1,219 mm) of maximum swing. Bourn & Koch redesigned and re-engineered this model in 2018, and the result differs from the larger machines in the line: direct drive on both the chuck and the grinding spindle, hardened and ground linear rails, and a full stainless steel enclosure.

Standard grinding horsepower is 50 hp (37.3 kW) at a grinding spindle speed of 720 rpm. The maker states that the direct drive grinding spindle provides up to 100HP, and increased grinding spindle horsepower is on the option list. The chuck turns at 6-24 rpm, infinitely variable, and carries up to 3,000 lb (1,361 kg).

Two servo controlled axes do the positioning, the carriage on X and the spindle head on Z, each with encoder feedback. The feed rate runs from 0.0001 to 0.010 ipm (0.0025 to 0.254 mm/min). Vertical range is 24 in (610 mm), with 36 in (914 mm) optional for tall work. A FANUC 35iB control with the proprietary Blanchard HMI runs the cycle, including a teach mode with conversational programming, fine grinding, and auto spark-out and retract.

This is a wet process, and the enclosure is built for it: stainless steel with an automatic door, a base flushing system and an auxiliary door with work-light for viewing the work zone. External coolant systems, automatic coolant valves, a mist collector and a 2A2T wheel adapter for super-abrasives are optional. The machine weighs approximately 30,000 lb (13,608 kg). Bourn & Koch names steel, ceramic, silicone and cast iron among the materials it grinds.

Frequently Asked Questions

01 How big a part can the Blanchard 22AD-42 grind?

Maximum swing is 48 in (1,219 mm) over a 42 in (1,067 mm) magnetic chuck, and the weight capacity is 3,000 lb (1,361 kg). Vertical range is 24 in (610 mm) as standard and 36 in (914 mm) as an option. The grinding wheel is 22 in (559 mm) in diameter.

02 What horsepower does the Blanchard 22AD-42 have?

Standard grinding horsepower is 50 hp (37.3 kW), with a grinding spindle speed of 720 rpm. Bourn & Koch states that the direct drive grinding spindle provides up to 100HP, and increased grinding spindle horsepower is listed as optional equipment.

03 What control runs the Blanchard 22AD-42?

A FANUC 35iB control with a proprietary Blanchard Human Machine Interface. It offers a teach mode with conversational programming, fine grinding, auto spark-out and retract, and a remote jog button for the magnetic chuck. The enclosure door is automatic and interlocked.

04 How fine is the downfeed on the Blanchard 22AD-42?

The feed rate range is 0.0001 to 0.010 ipm (0.0025 to 0.254 mm/min). The spindle head (Z-Axis) and the carriage (X-Axis) are each powered by a servo motor with encoder feedback for accurate positioning, and the construction list names hardened and ground linear rails on both axes.

05 How does this model differ from the larger Blanchard 32HAD-60?

The Blanchard 32HAD-60 has a 60 in (1,524 mm) chuck, a 32 in (813 mm) wheel, 100 hp (74.6 kW) and a 10,000 lb (4,536 kg) capacity. The smaller machine answers with direct drive chuck and spindle rotation, linear rails and a full stainless steel enclosure, which the feature list of the larger one does not name.
