Slide & Swing Asidemilling machine guards

The patented Slide & Swing Aside Milling Machine Guard has been designed to meetthe stringent guidelines laid down by both legal requirements and industrial necessity. Itis manufactured using impact resistant clear polycarbonate and gives good visibility,immediate access and maximum operator protection. Its unique design ensures that theguard does not impair the performance or the versatility of the machine.

This is the first guard of its kind which enables either small workpieces or large castingsfitting and overhanging the milling machine table to be completely protected but at thesame time giving immediate and complete access to the piecepart or casting beingmachined. Each of the front panels can slide to the right or left and swing aside on theirown axis out of the way, finishing in a position parallel to the end panels.

The advantage of the Slide and Swing Aside movement is that you can obtainimmediate access to the whole length of the table for loading and unloading largeworkpieces, and although the panels slide aside they will not take up any more roomthan the actual length of the table.

Where large castings are being machined that overhang the table, you can slide theguard forward and lock into the position required. This may however leave a gap on theunderside of the guard between the table and front panels. To overcome this situationan Infill Guard can be fitted which also keeps the operator and machine clear fromswarf and coolant.

The guard is supplied in two separate assemblies which aremounted at each end of the table. A plate fitted with arectangular locating block having equivalent width to the tableslots is positioned at each end of the table in one of the “T”slots and the parrallel sole bars are clamped to the mountingplate by two socket cap screws (allen key supplied). The twoparallel sole bars support a kingpost to which a pivotingbracket is fitted supporting a ball bearing sliding track towhich the polycarbonate transparent front panels are fixed.

1 Back GuardFor guarding the rear of the table at either side of the headstock.Thetwo clear panels are both located on a single slide runner assemblywhich is fixed to the ends of the parallel sole bars. Top support isprovided by dual rollers. As the table moves from side to side thetwo linked panels are free to slide in their mountings thus providingcomplete rear protection at all times with no hindrance to tablemovement.The standard back guard is suitable for tables up to1600mm. For larger tables a telescopic or custom backguard isavailable.

2 Electrical InterlockAdditional operator safety can be provided by the installation of thiscompact yet totally effective and reliable safety switch. As the twofront panels are closed the actuator tongue enters the switch bodyand closes internal contacts linked to the machine controls thusallowing machine operation only when the guard is properly closed.Interlocks are normally fitted to the right hand side on SSA/2/3/6 andto the left hand side on SSA/00/1.

3 Coolant Drip Trays (Infill guard)To protect operators from coolant drip and overspill of swarf from thefront of the table and also prevent access underneath the frontpanel. Particularly relevant when machining large irregular castingswhich overhang the machine bed.Two types are available, one hasan adjustable tray width to cater for different overhangs.The othertype is a fixed width tray with a lip on three sides to which can beattached an optional brush strip to seal the small gap between thetray and the bottom edge of the front guard panels. Both typeslocate to the sole bars. Specials are available upon request.

4 Sliding Access DoorA portion of the front panel can be converted to a sliding accessdoor allowing access to the machines operating levers, e.g.Bridgeport Mill for quill feed arm access.The access panel can bepositioned on either the right or left panel.The use of two slidingaccess doors, one on each panel can also be supplied.This option isstandard on the SSA7 but is also available on other guards ifrequired.

Just Swing Asidemilling machine guards

The JSA-1E Interlocked Vertical Milling Machine Guard is suitable for Bridgeport Series1 vertical milling machines or similar.

Its operator friendly proximity guard provides operator protection without the usualconstraints of a full table guard. When not required it simply swings aside allowing fulloperator access to the machine table for setting and measurement, etc.

Not only is it suitable for tool room machines but also R & D workshops, prototype workand small batch production machines. It has a three sided framed polycarbonate screenwith support arm and mounting bracket with an optional right hand side cut-out foraccess to quill feed arms (common to Bridgeport machines). Adjustment is easilyattainable in both Z and Y axis.

The guard can be fitted to either the left or right hand side of the machine, the standardbeing on the left.

Lathe GuardsTXS saddle mount lathe shields

This protection shield is normally mounted on the cross-slide of the lathe althoughmounting to other parts of the machine is possible. The steel structure with a 4mm thickpolycarbonate window allows protection from chips and coolant, along with visibility tothe point of operation.The front portion of the shield hinges up for access.The shield isideal for applications where a simple chuck guard is insufficient, as it protects theoperator when machining is taking place at a distance from the headstock.

Lathe Guardsthe LXS lathe chuck guards

The LXS Lathe Chuck Guard consists of a semicircular construction made from highimpact resistant transparent material which is mounted on to a chromium platedextension tube, fastened to the headstock of the lathe.

The semicircular guard covers the upper half of the lathe chuck as shown above.

Access to the workpiece is quick and easy, the guard is lifted and swung away from theoperator.

The size of the guard required is dependant on the centre height of the lathe and thediameter of the chuck. On lathes up to a centre height of 7" there is only a smallvariation in diameter between the 3 and 4 jaw chucks, and therefore one size of guardwill suffice. On lathes in excess of a centre height of 7" there is a greater variation in thediameter between the chucks. It is therefore advisable to use two guards to giveadequate protection, eg. LXS 653 shown on opposite page with LXS 400 and LXS 600.

The chromium plated extension tube to which the guard isfastened is mounted to the headstock of the lathe by means ofa universal mounting bracket incorporating an electrical safetyinterlock. The interlock incorporates cam operation, is sealedto IP 66 and conforms to EN 1088 and EN 60947-5-1. All unitsare provided with PVC covered flexible steel conduit and awiring diagram.

Drill GuardsDXS safetispeed drill guards

The Guard has been specially developed to give maximum all round protection for theoperator with a high standard of visibility without adversely affecting operation time.

The drill guard consists of two major components.The drill guard mounting which isfitted to the quill of the machine and the drill guard sleeves which clip into the mountingand are held in position by three spring loaded ball catches and retaining screws.

The guard consists of two or three sleeves, the inner sleeve being a ribbed cage whichis held stationary in the guard holder. The outer sleeve is free to move up and down onthe inner cage and is fitted with a guide groove which gives radial movement to theouter sleeve thus preventing jamming.

The outer sleeve is fitted with a transparent acrylic window (as standard) held in positionby two slideways and a retaining screw. The window can be quickly removed andreplaced at regular intervals giving maximum visibility at all times. The outer sleeve restson the piecepart or jig. As the drilling operation takes place the inner cage moves downand automatically protects the window from metal slivers which are cut up by the edgesof the inner cage.

The basic drill guard (i.e. DXS-500) is bored suitable for a quill diameter of 2.75"(70mm). The 13 sizes of reducing bushes will cover any quill diameter down to aminimum of 1.5". Determine your quill diameter or point of fixing at the time of orderingand select the appropriate drill guard. If a bush is required, refer to the table opposite.The bush may be ordered separately. Sizes outside the standard range can be suppliedby our 'Specials' department.

Bushes are only used withthe ‘Type A’ mounting toreduce the bore size from70mm down to 37.85mm(shown opposite).

For quill diameters from70mm up to 95mm theType 1L, 2L and 3Lmountings should be used.

NOTE: NO BUSHESREQUIRED.

For other types ofmountings ‘Type AS1, B,1F and 2F’ should be used.

Chip Guardmagnetic based safety chip guard for minimuminterference

The Magnetic Based Safety Chip Guard can be attached to any ferrous part of themachine by means of the powerful magnetic base. The guards can be fitted with aspecial double arm, each arm having both a longitudinal and swivelling movement andthe guard can also be individually adjusted.This combination of movement allows theguard to be positioned at any angle.

The guards are made with a top curvature to deflect flying chips but 90% of the guardis a flat optically undistorted window through which the operator can clearly see thework in progress.
