Centerless Grinders
The base of our CLG Centerless Grinder is made of Meehanite casting designed to reduce vibration. The machine base provides stable support to the grinding wheel and regulating wheel assemblies to ensure a rigid machine foundation and better accuracy.
Both grinding and regulating wheel spindles are made of NiCrMo alloy steel, which is normalized, carbonized, hardened, and ground.
The regulating wheel utilizes a servo motor which provides infinitely variable speeds. The speed can be set digitally to reach constant surface speeds even when the diameter of the regulating wheel changes. Consequently, better surface finishes and roundness of the workpiece can be achieved. A belt driven transmission system is also adopted for the regulating wheel for less vibration and noise compared to traditional chain-driven systems.
A double inverted "V" slideway with optimum spacing for the regulating wheel assembly provides smooth movement and stable grinding operations.
A hydraulic dressing unit on both the grinding and regulating wheels with precisely handscraped guideways provides stable hydraulic movement and the best dressing effects. Various types of form dressing can be achieved with optional templates.
CNC models offer two axis servo control and the automatic compensation system can precisely dress forms with complicated edges. An infeed grinding cycle can be completed by simply choosing the grinding cycle mode (single or automatic) inputting grinding data and then pressing cycle start.
