NEW 2024 SHARP OD820S
Overview
2024 SHARP OD 816 SE UNIVERSAL CYLINDRICAL GRINDER (8" X 16" , Automatic Infeed)
FEATURES
♦ Stable and rigid spindle head
The spindle runs on precision bearings, assuring maximum spindle stability. It guarantees
outstanding grinding accuracy for external dia., internal dia., (optional) & end face. The
spindle head swivels +90° ~ 30°. The spindle head on the OD-816 series machines provides
variable speed, changed by a frequency inverter.
♦ Precision Wheel Head
The grinding wheel spindle is precision-machined from high-quality alloy steel, normalized,
tempered, carburized, sub-zero treated, precision ground, and mirror-effect treated..
♦ Special hydrostatic bearing
The wheel spindle runs by using a special hydrostatic bearing and is especially ideal for
precision grinding work. It features high speed, no friction between metals, no heat
generation, deformation-free, extra high accuracy, and continual use. Hybrid hydrostatic
bearings are used for the wheel spindle bearings. Metal-to-metal contact will never occur with
these highly rigid.
♦ Plunge Grinding
♦ End Surface Grinding
♦ Taper Grinding
♦ Internal Grinding
♦ Shoulder Grinding
