Product Features
Machine main chassis is made of high-grade cast iron FC-30 melted by advanced induction furnace then cast by resin cores. It is heat treated by normalizing procedure prior to machining to ensure greater stability and rigidity
Wheel spindle is made of SNC-21H, Ni-Cr-Mo alloy steel and case-hardened, carbonized, and then sub-zero degree treated by computerized controlled installation. Surface hardness is more than HCR 62º for a dept of over 1.5mm. Hardness at hub is about HRC 30º, resistance to wear and not easily deformed
Swivel and tilt regulating wheel to accommodate workpiece requirements
Lubrication system for hydraulic dressing and enforced spindle lubrication. The oil tank is located outside of machine for easy maintenance. Two layers of filter plus pressure regulator to ensure the cleanness of lubrication oil and oil film thickness consistency to extend wheel spindle life span and accuracy
Wheel dressing device is made of FC-30 cast iron and precision ground. It is driven by hydraulic system with stepless speed regulator for easy and steady dressing operation
Servo motor regulating wheel can be adjusted to ideal linear speed. Constant linear speed while diameter of regulating wheel changes to maintain superior accuracy and grinding finish (JHC-12S)
