Type : RC – 18/RC – 18B

Features :

The machine bed is made of height quality “MEEHANITE” case iron and has aging treatment and precision ground. No worn out.
All gears are made of SNCM 220 alloy steel having been normalized, carburized hardened and precision ground .No vibration and noise.
The angle of the regulating wheel dressing unit can be swivelled according to workpiece requirements in order to enhance accuracy.
A Japanese servo motor is used as the regulating wheel motor which provides infinitely variable speed change from 0-295 rpm and can be adjusted to ideal linear speed.
The servo motor is driven directly by worm and worm gear. This can reduce vibration during grinding and consequently achieve the best roundness.
The grinding and regulating wheel spindles are made of high quality alloy steel (SNCM 439), induction hardened super finished. They are sturdy and strong enough to permit heavy duty grinding at high speeds and assure superior surface finish.
The upper slide can be rapidly and precisely swivelled up to ±5 degree in order to grind taper in feed grinding and provide perfect contact between work piece and grinding wheel in true feed grinding.
Both grinding wheel and regulating wheel dressing units are hydraulic traversed, traverse speed is infinitely adjustable. Dressing slides are made of special alloy cast iron and hand scraping. Assures smooth dressing and high accuracy.
One pressure switch is provided in the grinding wheel spindle lubrication system so that the spindle motor won’t rotate while the lubrication pressure is reduced. This prevents the spindle from dry running and damage.
During grinding, it cools down hydraulic oil temperature and there for reduce size vibration also enhance grinding wheel spindle life.
