THE PERFECT CONCENTRICITY GAGING SYSTEM
The Rollomatic “V-Block” Concentricity Pro is capable of mea-
suring the run-out on cylindrical components below .00004”
(1 micron) and can ideally be used in the cutting tool, punch-
ing, bar-turning, semi-conductor, automotive and aerospace
industries.
The combination of a special rotary drive (patent pending)
together with the traditional “zero-error” carbide V-block sys-
tem offers concentricity gaging for use on comparators or as
a free-standing unit with dial indicators or laser scanners.

THE PERFECT CONCENTRICITY GAGING SYSTEM
The Rollomatic Concentricity Pro represents a totally new approach to concentricity gaging and
provides guaranteed improvements in accuracy and efficiency. This quality inspection device is
available in 3 versions:
Version 1 As a stand-alone unit for comparators and contour projectors
Version 2 Mounted on a surface plate with precision dial indicator and articulated arm
Version 3 Mounted on a surface plate with a high-accuracy laser scanner to measure
diameter and concentricity
(for measuring “odd - flutes” on cutting tools, a PC program is available - sup-
plied by Rollomatic)

CHAPTER 0. INTRODUCTION
This concentricity measuring instrument was designed to complement the Rollomatic
family of products and promote Rollomatic’s image: precision & concentricity in
grinding tools.
Several features of the ”Concentricity Pro” are being patented.
The ”Concentricity Pro” is available as a separate instrument to be mounted on a
profile projector, as a stand alone concentricity measuring station or with a steel
base and a laser scanner.
CHAPTER 1. CALIBRATION
The Concentricity Pro has been calibrated before shipment. If it becomes neces-
sary to calibrate it, follow the procedure described here:
PHOTO 1.1–A
A. Place the Ø 12.07 mm calibration pin (which comes with the concentricity
pro) under the silver colored stopper plate as shown on photo 1.1–A, and
lock it in place tightly with the stopper lock.
B. Space the ”V block pair unit” approximately 25mm (1”) as shown on
photo 1.1–A and tighten the ”V” lock (photo 1.1–B).
C. Place the Ø 5 mm blank supplied with the concentricity pro on the “V”
guides. Bring the tool rotation arm onto the tool shank. Loosen the screw of
the silver colored stopper plate (photo 1.1–C) and bring the ”precision
stopper rod” down until it touches the 5 mm blank. Tighten the screw.

The stopper rod has a ball shape end. The calibration procedure ensures
that one point of the ball will touch the exact center of the blank to be
measured (if the blank is not cut straight, rotating it will create an axial
movement).
NOTE: In case of wear-off of the precision stopper rod rotate the rod.

CHAPTER 2. USING THE CONCENTRICITY PRO
Before using the Concentricity Pro, clean well the tool to be measured.
A. Place the shank of the tool to be measured under the silver colored stopper
plate as shown on the photo 2.1–A. Slightly press the stopper plate and
tighten the stopper lock.

PHOTO 2.1–B
B. Space the ”V”–block pair unit as desired (they should be spaced as much
as possible) and tighten the ”V” lock. Put the tool to be measured on the
”V”– blocks and bring the tool rotation arm onto the tool shank approxi-
mately at equal distance from both ”V” blocks.
C. Rotate the handle to rotate the tool. Because the tool rotation arm is slightly
inclined, turning the handle clockwise will push the tool against the stopper
for very accurate tool rotation.

CHAPTER 3. CHANGING THE “V“ GUIDES
A. Move the “main” block to the very right, so that the pins of the block reach
beyond the guide rail.

MAIN BLOCK “V” LOCK
B. Fix the main block in position by tightening the “V” lock. Attach the front
“V” block by means of the pins, which ensure a perfect positionning of the
“V” block.
Fix the “V” block with 2 allan screws (see PHOTO 3.1–B).
PHOTO 3.1–B
••• NOTE:
The main block must be set back a few millimeters so that the front “V”
block rests correctly on the surface plate.

C. Position the main block at the desired distance, attach the back “V” block
and tighten the “V” lock.
The “V” block is attached to the main block via the pins.

The “V” blocks are now mounted.
