Controller
FANUC (Standard)
~ PARAGON CNC series internal grindíng machines have the latest technology and
outstanding reliability in digital control that is designed to easily automate, each
with a LCD screen display system.
~ PARAGON provides an unique, convenient operating interface for easy data input,
and programming that reduce set-up time and increase efficiency.
~ For the advanced user, programs can be downloaded by RS-232 interface or input
from a flash-card through a PCMCIA port.
~ The high accuracy is assured and is provided by powerful senıo motors directly
driven by C1 class ballscrews, minimizing backlash.
✓ Maintenance function such as a diagnosis function is provided to quickly identify the
cause of a failure.
The amount of dressing during grinding will automatically and continuously
compensate for grinding wheel cutting and dressing in canned cycles.
 Manual Pulse Generator (M.P.G.) handwheel is provided for easy setting
and nimble adjustment.

WHEELHEAD
Slíde table
The wheelhead motion (X-axis) is driven by servo motor with C1 class
ballscrews and precision linear guideway, resulting in rapid motion
and accurate positioning for internal grinding.
WORKHEAD

Workhead Swível Angle
Workhead utilizing precision taper roller bearings and ball bearings on
both sides can take both radial and axiallarge loads due to greater contact
area to compensate for spindle thermal expansion and operate with
zero radial clearance rigidity.
Automatíc Belt Tensíon
Adjustment
Eliminates the need for manual adjustment to reduce maintenance
time, also assure full power transmission to additionally extend
the service life of precision bearings inside the spindle.
Sensor
The sensor mounted on workhead is designed for (a) easy set- up of
grinding wheel and workpiece (b) monitor rotation rpm (c) belt status
indication.
РARAGON
Gríndíng Wheel Dressíng
Devíce
One unique dresser device combined with touch sensor technology features
constant coordinate position that oifers precision profile dressing.

Multí-Function Workhead
Workhead can be equipped with rotary cylinder, chuck applications or fixture
for varied workpieces.
Workhead will swivel forward 13 degrees and backward 5 degrees for taper correction or various profile grinding.

The machine base is manufactured from high quality Meehanite cast iron, low center of gravity, featuring rigidity over 108 N/m and natural
frequency over 150 Hz, analyzed by advanced Finite Element
Method (FEM). A1ong with vibration stress release, these outstanding
structural features assure high strength, maximum damping
capability, and longer service life.
Extra fine hand scrapped over the entire contact surface of guideways guarantees high accuracy and maximum durability for axes movement.

Wheelhead Guídeways
(X-axís)
The table motion (CNC series), driven by servo motor, features with high rigidity and durability to extend senıice life.
Guídeways (Z-axís)
Extra wide V guideways on base combined with great span in between
and constant hydraulic lubrication, exhibit outstanding stability during grinding operation and micro-feed accuracy. The table motion (CNC series) is driven by servo motor with C1 class ballscrews.
C1 Class Ballscrews
Feature automatic lubricator, low friction coefficiency, and are
pretensioned for increased rigidity and high positioning accuracy, providing minimum feeding accuracy in 0.1 μ m on X axis and Z axis.

End Face Gríndíng Devíce (Optíonal)
Grinding wheel is driven by powerful motor (1 HP) for grinding end face at the edge of workpiece.
Automatic in-process Gauge
This device automatically and continuously measures the workpiece being machined and compares the actual size to pre-set values, bringing the workpiece to the accurate dimension. (CNC Series
Optíonal)
Rotary-type Díamond
Dresser
Driven by a servo motor, it offers precision profile
dressing and high torque output. Service time is at least 50 times more than single-point diamond dresser. (CNC Series Optional)
