Low Speed Diamond Wheel Saw

Model 650

The Model 650

Low Speed Diamond Wheel Saw

The Model 650 Low Speed Diamond Wheel Saw

is a compact, multipurpose, precision saw

designed to cut a wide variety of materials with

minimal subsurface damage. It's low speed

makes it possible to cut fragile materials that

would otherwise fracture and soft materials that

would load the diamond wheel on a higher speed

saw. A variety of sample holders provides a

means for mounting any shape sample while

goniometer adaptability simplifies cutting oriented

crystals.

Special Features

Belt drive system eliminates gear breakage which is

common with less reliable fiber gear driven designs.

Coolant reservoir is lowered and easily removed by

opening an access door located on the front panel.

Both coarse and fine sample position adjustments

allow rapid and accurate sample positioning.

Polyethylene coolant reservoir enables the use of

both water soluble and oil based coolants.

Automatic termination of the cutting process is

controlled by an electromechanical downstop which

minimizes supervision.

Cutting arm pivots on a set of precision bearings

rather than on the micrometer shaft which ensures

accurate and repeatable sample positioning.

Multiple diamond wheels can be used to gang slice

materials up to 2" in length.

Utilizes a high torque 1/15 HP DC motor to provide

sufficient power for difficult materials.

The 3 standard sample holders allow mounting of

virtually any shape sample.

2-Axis Goniometer can be transferred from an

x-ray track for cutting precisely oriented crystals.

It's small size and simple operation make it ideal for

glove box or hot cell adaption.

Operation

A sample is mounted to a sample holder and attached to

the arm. An appropriate load is applied by adjusting the

counterbalancing weight and the automatic stop switch

is set. The sample is positioned in any starting position

relative to the diamond wheel and then a micrometer is

used for precise sample positioning. With the diamond

wheel rotating slowly and coolant in the reservoir, the

arm is gently lowered until the sample touches the

diamond wheel. Cutting will continue until the automatic

cutoff switch is triggered.

Cutting Wheels

The Model 650 is designed to cut with diamond, CBN

and abrasive wheels. Diamond wheels are used for most

applications while CBN wheels are primarily used for

cutting ferrous based materials. Abrasive wheels (Al2O3

and SiC) can be used for cutting both ferrous and

nonferrous materials and have also been used for dry

cutting of superconductor materials. SBT provides a wide

selection of cutting wheels and the separate consumables

catalog provides details on selecting the proper cutting

wheel for your application.
ACCESSORIES

Model 65001

Single-Axis Goniometer

The Model 65001 has a

graduated scale with a 0.2°

vernier and can be rotated

360°. This rotational capability

makes it ideal for precisely

slicing single crystals. The

sample is mounted to a block

using a low melting point wax

and the block is subsequently

clamped into the Model

65001. Wax mounting of the sample ensures that the cut

piece will remain attached to the holder and will not be

damaged by falling after being cut.

Model 65003

Double Clamp

Sample Holder

The Model 65003 is a clamp

type holder designed to clamp

both ends of a round or

rectangular rod while cutting

between the two clamped

positions. The Model 65003

can also be used as a single

clamp holder to hold

encapsulated metallurgical samples up to 1.25" in diameter.

Model 65004

Petrographic

Sample Holder

The Model 65004 is designed

to use a vacuum to hold

2.5cm x 5.0cm glass plates,

onto which petrographic or

other samples are waxed,

while making saw cuts parallel

to the glass plate. The glass

plate is held against a stainless

steel support plate with vacuum and is placed firmly against

3 locating pins to maintain its position.

Model 65005

2-Axis Goniometer

The Model 65005 is a 2-axis

goniometer used for orienting

and cutting single crystals.

The Model 65005 can be

mounted on an x-ray track for

orientation using the Model

65011 Track Mount and then

transferred to the Model 650

for cutting. With the sample

mounted to the goniometer, the vertical axis can be rotated

±50° from the 0.2° vernier on the arm.

Model 65006

Vise

The Model 65006 Vise is

designed to hold flat,

round and irregularly

shaped samples without

the need for a mounting

wax. The entire vise can

rotate 360° in the

horizontal plane. An

extended v-notch jaw

enables the mounting of cylindrical samples up to 1.25" in

diameter including encapsulated metallurgical samples.

Model 65007

Right Angle Holder

The Model 65007

Right Angle Holder is

designed to hold

mounting blocks parallel

to the saw blade.

The Model 65007

accommodates stainless steel mounting

blocks up to 1.5" in

diameter which are

directly transferable to the South Bay Technology series

of lapping and polishing fixtures.

Model 65008

Ball Joint Holder

The Model 65008

Ball Joint Holder is

designed to allow a

wide range of motion

to position the

specimen for cutting.

The Model 65008 is

mounted similar to the Model 65007 Right Angle Holder

and consists of a specimen mounting block which is

mounted to the ball joint holder. The ball joint allows the

specimen to be adjusted in any direction up to 10°

maximum. This provides a wide range of motion and

flexibility to cut oddly shaped specimens.

Model 65011

Track Mount

The Model 65011 Track

Mount is designed to mount

the Model 65005 2-Axis

Goniometer onto a 1.99" or

2.19" wide x-ray or optical

track for crystal orientation.
Model 65017

Bone Chuck

The Model

65017 allows you

to hold the

sample utilizing a

series of 10 independently adjustable mounting screws.

These mounting screws make it possible to hold irregularly

shaped specimens and rotate them 360 degrees in a

horizontal plane. The Model 65017 Bone Chuck attaches

to the standard work arm in place of the standard sample

holders.

Model 65018

Right Angle

Bone Chuck

The Model

65018 attaches

to our Model

65007 right

angle holder. The

65018 includes

a 65007 Right Angle Holder and a 65017. It holds the

bone at a right angle relative to the 65017. It can still

rotate 360 degrees in the horizontal plane (although

the 65017 is now at a right angle), but the 65017 is

held in a fixed position within the 65007 utilizing a set

of locating pins. The 65017 can be rotated in 90 degree

increments as there are multiple sets of pin holes for

the locating pins.

Model 65019

Adjustable

Right Angle

Bone Chuck

The Model

65019 uses the

65017 holder

and it mounts

into a specially

designed right

angle holder. As there are no locating pins in this design,

you can rotate the sample 360 degrees in both a

horizontal and a vertical plane.

Model 65012

Dressing Stick Holder

To ensure e f ficient

performance from a

diamond wheel, it is

imperative that the

wheel is dressed on a

regular basis to expose

new diamonds for

cutting. The Model

65012 Dressing Stick

Holder mounts directly onto the Model 650 and provides

a means to carefully apply a silicon carbide dressing stick

to and retract from the diamond wheel.

Model 65014

RotaCutterTM

The Model 65014

is an optional

specimen arm that

mounts in place of

the standard arm

on the Model 650

and provides

rotation of the sample during cutting. The RotaCutterTM

can cut irregular shapes as well as cylindrical samples

up to 2.25" in diameter. Rotating the sample during the

cutting process produces thinner samples in a shorter

time and with a better surface finish. The RotaCutterTM

maintains a point contact between the diamond wheel

and the sample which accounts for the increased cutting

rate. Materials from hard ceramics to soft metals can

now be cut in a fraction of the time required on a

standard saw. The Model 65014 RotaCutterTM includes

the cutting arm , a specimen holder and a variable speed

power supply. The power supply is also equipped with

an auxiliary outlet for an optional work lamp. This optional

halogen lamp is ideal for illuminating the sample area

for inspection while cutting or for alignment when using

the Model 65040 Alignment Microscope.

Model 65016

Ball Joint

Work Arm

The Model 65016

is a new arm that

incorporates a ball

joint at the point

where the sample

holders attach to the arm. This allows the use any of our

standard sample holders and provides the ability to swivel

them up to 10° in any direction. The ball joint work arm

simplifies the specimen mounting process as cutting plane

adjustments can easily be made after the specimen has

been attached to a sample holder.
