The PELCO^® Precision Low Speed Saw is a compact, multipurpose, precision saw designed to cut a wide variety of materials with minimal subsurface damage.

Its low speed makes it possible to cut fragile materials that would otherwise fracture as well as soft materials that would load the diamond wheel on a higher speed saw.

A variety of sample holders are available, providing a means for mounting any shape of sample, while multi-axis goniometer adaptability simplifies cutting oriented crystals.

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 to define the end of the cut.

The sample is positioned in any starting position relative to the diamond blade and then a micrometer is used for precise sample positioning.

With the diamond blade rotating slowly and coolant in the reservoir, the arm is gently lowered until the sample touches the diamond blade. Cutting will continue until the automatic cutoff switch is triggered.

Cutting Blades

The PELCO^® Precision Low Speed Saw is designed to cut with diamond, cBN and abrasive blades. Diamond blades are used for most applications while cBN blades are primarily used for cutting ferrous based materials. Abrasive blades (Al₂O₃, SiC) can be used for cutting both ferrous and nonferrous materials and have also been used for dry cutting of superconductor materials. Ted Pella, Inc. provides a wide selection of cutting blades and our catalog of consumables provides details on selecting the proper cutting blade for your application.

Features

• The belt drive system eliminates gear breakage which is common with less reliable fiber gear driven designs.
• The 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.
• The 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.
• The cutting arm pivots on a set of precision bearings rather than on the micrometer shaft which ensures accurate and repeatable sample positioning.
• The PELCO^® Precision Low Speed Saw utilizes a high torque 1/15 HP DC motor to provide sufficient power for difficult materials.
• Automatic overload protection shuts down the motor if the blade binds while cutting.
• A wide variety of sample holders allow mounting of virtually any shape of sample.

Ordering Information

The PELCO® Precision Low Speed Saw is shipped with one each of the 75001 Single-axis Goniometer, the 75003 Double-clamp Sample Holder, and a 1″ x 3″ aluminum sample mount.

This kit is sufficient for mounting and cutting most sample types. Please note, the PELCO® Precision Low Speed Saw does not ship with a blade, as no one blade is appropriate for all applications. Please specify a blade when requesting a quote.

All accessories can also be ordered individually.

Additional Accessories

Additional accessories available include Aluminum and Graphite sample mounting blocks (for use with Single-axis Goniometer), blade spacers of various thicknesses, and blade supports of different diameters.

It is recommended that the largest blade support (e.g. minimum blade exposure) possible be used for a given sample diameter.
This will increase precision and help prevent damage to the blade. The 2.43\” diameter blades supports are supplied with the saw.

Several different widths of blade spacer are also available, allowing mounting of multiple blades or increasing the range of blade offset. the 0.75\” Blade Spacers are supplied as standard.

The blade position is controlled with a metric micrometer.
An inch micrometer assembly is also available as an additional accessory.
