Introduction

Tools Required

Standard hex key set

1 Meter straight edge

Feeler gauges

engineers square

Shim pack

Parts Required

R0000559 Bench assemble machined parts

R0015326 Bench Assemble Roller Backfences

Étape 1 - Unless otherwise stated

Use locktite 243 on all fasteners

Use loctite 572 on all threaded pneumatic connection

Pen mark all fasteners to show finalised

Étape 2 - Attach backfence support

Attach pre machined back fence support to main frame

Use 4 off M8 x 25 socket caps , do not apply adhesive

Set assembly to maximum height position in fixing slots

Étape 3 - Attach roller fences

Attach pre build roller fences to backfence support bar using M6 x 35 socket caps . Do not apply adhesive

Étape 4 - Set squareness

1 Use engineers square to check squareness of roller fences to cut tables. Check at multiple points

2 Identify movement required to adjust square.

Gap between square and roller:

Top = add shim to top of bar

Bottom = Add shim to bottom of bar

3 Cut and add shim ensuring shim bottoms out on M8 fastener, as this will act as a datum

...Only use single shims to adjust , do not add shims together to increase size.

4 Adjust until rollers are square with full tension on M8 fixings

Étape 5 - Set alignment between roller fences

1 Use 1 meter straight edge to check alignment of rollers. Identify which direction movement is required to achieve alignment of all rollers.

Tolerance 0.002"/0.05mm

2 Adjust using shim at indicated point on either / both arms

...Each arm should only ever have 1 side with shim This retains datum positions

3 Adjust until all roller are within tolerance to straight edge

Étape 6 - Set height

1 Set heights of all rollers to cut tables to a gap of 1.5 mm . tolerance -+0.5mm

2 Use slots shown for main adjustment

3 Use counterbores shown for fine adjustment

4 Check all measurements on all rollers are correct

Étape 7 - Recheck all settings

1 Finalise all fasteners shown. 8 off M8 indicated should be set to 40 nm toque setting

Once final adjustment has been done, recheck all settings as movement is possible when adjusting

2 Table /roller squareness

3 Roller alignment

4 Roller height

Étape 8 - Remove all sharp edges

Once all fasteners are finalised and settings checked, shim over hangs must be removed.

Ensure no cut points are left from exposed shims
