The AES HRG2000 is a 6-axis CNC machine able to grind the ball tracks of housing and race, or the windows of a cage. It can grind radial, dual arc (Honda), cross groove (pancake) and Tripot track pr
files, and round or gothic arch track forms. It uses low cost, dressable grinding wheels able to grind up to 350 parts per wheel. (CBN plated wheels for cross groove)
The main elements of the machine are arranged on a very strong, rigid, steel base, as follows:
Features a 7.5KW high frequency, chiller-cooled grinding spindle with infinitely variable speed up to a maximum of 45,000 rpm. The spindle is held horizontally in a cast iron housing set on a slidewa
system giving 3 axes of linear movement (X, Y and Z) to the grinding wheel relative to the workpiece.
Features a CNC servo driven index head (U axis) and interchangeable work holders including a collet chuck for housings, a universal fixture for cages and expanding mandrel for races. The workhead is
et horizontally on a table giving 2 axes of movement: radial for track grinding (C-axis) and linear for control of track centerline (b-axis).
Achieved by a 0.25KW high frequency, air-cooled spindle, with a maximum speed of 16,000 rpm (4 speeds). The dressing spindle is held horizontally in a fixed bracket near to the grinding spindle. It r
tates a diamond-disc that dresses the track form onto the wheel by CNC interpolation of grinding spindle axes X and Z.
Other features include:
> Slideway tables driven by the latest GE Fanuc brushless AC servo motors and large diameter ball screws on sealed linear ways.
> Table positions controlled by absolute encoder feedback through fiber optic cables to a GE Fanuc 18iMB CNC.
>Machine mounted electrical and electronic control cabinets.
> Slideway lubrication by pressurised oil mist .
> Slideway protection by wiper seals and bellows.
> High pressure (12 bar), temperature controlled (25ºC), mineral oil coolant system, dual cleaned by magnetic separator and pressure bag filter.
> Pre-grind setting for housing and cage by manual fixture.
> Pre-grind setting for race is automatic in cycle.
> Machine base is painted with two pack epoxy blue and enclosure stove enamelled grey.
> Simple program change by manual data entry input of parameter values.
> Optional language CNC and parameter display.
> Machine: Width 160 cm (5'3"), Length 230cm (7'6"), Height 182cm (6'0") excludes oil mist extractor
> Coolant system: Width 122cm (4'0"), Length 188cm (6'2"), Capacity 236 litres (65 gallons)
> Weight: 2756 Kg (6063lbs)
> Electricity 380/415/460/480 volts, 3 phase, 50/60 Hz, 60 amps per phase
> Compressed air minimum pressure 5.5 Bar (80 psi), 1.0 m³ /min (35 ft³/min)
