Price estimate
We do not have a price for the Palmary PCB-6040 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 Palmary PCB-6040 is a CNC centerless grinder with wheels 405 mm wide: a Ø610 mm grinding wheel and a Ø355 mm regulating wheel. It grinds Ø1 to Ø150 mm and is the machine in Palmary's photograph and video for this pair of models, shown in the video with a gantry swinging type loading device.
A 405 mm grinding zone is production equipment. Palmary's summary of the pair is short: super rigid structure, double support grinding wheel spindle, wider wheel suitable for efficient mass production. The grinding wheel motor is 40 HP (30 kW), up from 30 HP on the PCB-6030, and wheel speed is 45 m/s (8,858 ft/min).
The lubrication columns of the table differ between the two models. For the PCB-6040 both the grinding wheel and the regulating wheel spindle are listed with an automatic lubricator, where the PCB-6030 has oil mist and grease. If spindle lubrication type matters to your maintenance practice, have Palmary confirm which applies.
The regulating wheel is driven by a 5 kW (6.7 hp) servo at 10 to 200 rpm. It tilts +5° to -1° and swivels ±2°; its dresser swivels ±5° with a 0 to 20 mm offset. The feed slide is a hand scraped V and flat. Wheel and flange are formed in one piece with the spindle on both sides, according to the accessory list, so wheel changes are a planned job: a grinding wheel exchanger and jib crane are options. Weight is 7,000 kg (15,432 lb).

Strengths & Limitations
Strengths
- 405 mm wide wheels for high-volume through-feed and long infeed parts
- 40 HP (30 kW) grinding wheel motor at 45 m/s (8,858 ft/min)
- Double support grinding wheel spindle
- Shown by Palmary with a gantry swinging type loading device
Limitations
- Flanges are one piece with the spindles, so wheel changes need lifting equipment
- Listed weight of 7,000 kg (15,432 lb) is the same as the narrower PCB-6030
- Regulating wheel tilt of +5° to -1°
- Spindle lubrication is listed differently from the PCB-6030; confirm the type
