PALMARY OCD-3260 CNC grinding machine was built in 2020 by the
Taiwanese company Palmary Machinery Co., Ltd. The machine, designed to
grind holes and rotary surfaces with a maximum diameter of 320 mm,
offers excellent machining precision and efficiency for many years of
intensive operation. To achieve this, a number of state-of-the-art
components are used, such as a specially constructed spindle made of
high-quality steel alloys which is mounted on precision bearings. In
turn, the design of the grinding wheel spindle uses special
hydrostatic bearings, which achieve high operating speeds with no
friction between the surfaces. This eliminates heat energy and thus
the creation of deformations.
The working head, driven by a powerful servomotor, rotates in a range
of -30° to +90°. All guideways are lubricated by an advanced
automatic hydrostatic system, ensuring, among others, extremely smooth
movement and high feed accuracy. The PALMARY OCD 3260 CNC cylindrical
and internal grinding machine is offered with an extensive range of
equipment, including a magnetic chuck, a diamond disc for shaping
grinding wheels and an intuitive FANUC numerical control. The total
weight of the machine is 3600 kg.
