1. Introduction

Edge finishing of acrylic, polycarbonate and similar thermoplastics can be a labour

intensive procedure using traditional techniques. Regeneration of the sawn edge

using the Diamond Edge Polishing technique produces a high quality, square and

gloss polished finish, cost effectively and without heat and stress. This results in

improved serviceability and will eliminate cracking problems if subsequently

cemented.

The 1550 Diamond Edge Polisher is the first UK designed and manufactured

machine for this process and will convert a good sawn edge to a polished edge at the

rate of, typically, one metre (40in) per minute.

The machine consists of three basic elements:

A high speed precision spindle, onto which is mounted a cutter hub fitted with two

polycrystalline diamonds and one single crystal diamond.

A transport system, which grips the material and passes it over the cutter.

An extraction system, which removes the swarf created by the polishing process.

2. Health & Safety Information

The 1550 Diamond Edge Polisher is fitted with interlock switches and sound

reduction to meet European legislation. The following points should be observed for

safe operation of the machine:

1. At no time should operators place their hands into the transport system

2. Always disconnect the machine from the mains supply before removing covers

3. Always wait for revolving parts to stop before attempting to adjust the machine

4. Always wear ear protection when using the machine

5. Never use the machine if any of the interlock switches are defective

6. Never attempt to bypass interlock switches

Should there be any queries regarding Health & Safety aspects of the 1550 please

refer back to the manufacturer or their nominated representative.

4. Positioning & Location

The 1550 weighs 410kg (902lb), and therefore needs to be positioned by

mechanical means. The machine can be lifted either:-

1. Under the main frame

2. Using the lifting holes drilled in the wings of the machine

3. Under the wings

Diagram 1. Lifting Points

Do not attempt to lift the machine other than by the approved lifting points

Option 1 is ideal when lifting the machine directly using a fork lift truck or hand

pumped truck.

Options 2 and 3 should be used when lifting the machine with slings.

The machine has four adjustable feet and it is important that it is sited on a firm,

preferably concrete, floor, for maximum rigidity. It need not be secured to the floor

or, necessarily, truly level but at least one of the feet must be adjusted and locked

with the foot adjustment locking nut such that all four feet are taking equal weight and

there is absolutely no evidence of instability.

1550 Inst Issue 6 05/09/06

5. Electrical Supply & Connection

The electrical specification of your new machine is as follows:-

Voltage 240V AC 50Hz (standard)

220V AC 60Hz (North America)

Current (max) 7.75A / 9.13A

Watts (max) 1860W / 2000W

Electrical supply to the machine must be in accordance with the details shown on the

rating label. As the colours of the wires in this mains lead may not correspond with

the coloured markings identified in your plug appliance, should the plug need to be

changed proceed as follows:-

Standard Specification

The wire which is coloured green and yellow must be connected to the terminal

which is marked with the letter E or by the earth symbol or coloured green and

yellow or green.

The wire which is coloured blue must be connected to the terminal which is marked

with the letter N or coloured blue or black.

The wire which is coloured brown must be connected to the terminal which is

marked with the letter L or coloured brown or red.

North American Specification

The wire which is coloured green must be connected to the terminal which is marked

with the letter E or by the earth symbol or coloured green and yellow or green.

The wires which are coloured black and white must be connected to the silver

coloured terminals. Polarity is unimportant.

!!IMPORTANT!!

THIS EQUIPMENT IS FITTED WITH FILTERING TO COMPLY WITH

ELECTROMAGNETIC LEGISLATION. THESE FILTERS WILL BE DESTROYED BY

FLASH TESTING. SHOULD A FLASH TEST BE CARRIED OUT ON THIS EQUIPMENT

DISCONNECT MAINS FILTER BEFORE PROCEEDING

Should there be any queries regarding the electrical requirements of the 1550

please refer back to the manufacturer or their nominated distributor.

7. To Polish an Edge

Your machine will be supplied set up with a cutter hub and ready to polish. To polish

an edge proceed as follows:

Select your piece of material

The 1550 will accept pieces of material of thicknesses up to 55mm. Should you wish

to polish thinner materials, these can be polished as packs up the 55mm maximum.

The minimum panel size which should be polished is 100mm square. The ends of

longer rods or bars of material can also be polished, but care should be exercised.

The 1550 will polish most thermoplastic materials. It must be noted however that

cutter life will vary depending upon the characteristics of the material being polished.

Cutter life can be improved by adjusting the transport and spindle speed to suit the

material. These adjustments should be made as follows:

Spindle

Harder materials – e.g. Cast Acrylic 50Hz (Max Speed)

Softer materials - e.g. PETg, Polycarbonate 30Hz (Min Speed)

Transport

Harder materials - e.g. Cast Acrylic Speed 2-3

Maximum speed that does not

chip the edge

Softer materials - e.g. PETg, Polycarbonate Maximum speed

Switch on the machine as described in Section 7 above. Set the spindle and

transport speeds and start the motors.

Load the material vertically onto the infeed (left hand) track.

Push the material until the transport system grips it and starts to feed it into the

machine.

At this stage, let go of the material, and let the machine transport it over the cutter

and polish the edge.

Once the material has been released from the transport, remove and inspect.

Note that the piece being polished must have exited the transport system before the

next piece is loaded. Failure to observe this could result in damage to the cutters.

After use, switch off the machine.
