Plastics Knowledge: Pantograph Milling Machine

Pantograph milling machine: It's a robust, accurate and reliable machine with a

pantograph arm length of 400 mm and with reduction ratios from 1 : 1.5 to 1 : 10. The main spindle is fitted with high precision bearings to provide twelve speeds from 1,200 to 13,000 rpm. Swiveling points of the pantograph arm run in needle roller bearing making tracking very accurate.

Features:

1. The machine body is of close grain cast-iron

2. The main spindle is fitted on high precision bearings and has 8 speeds ranging from 1100 to 12000 rpm. This wide range of speeds make it possible to use the correct speeds for different types of material

3. The swiveling points of the Pantograph arm system run in needle roller bearings giving a ling life without adjustment. Master shapes can be traced with high sensitivity and accuracy with the sensitive hinge system.

4. These Three Dimensional Pedestal Type Pantograph Milling Engraving Machines are hand operated and have very wide applications

5. The machines can be used for Die-Sinking work such as Coining Dies, Forging Dies, and pattern-makers shop

6. The machines can be used for light milling work also.

7. Foot operated switch leaves both hands of the operator free. The operator can comfortably, in a sitting position, reach all the controls for adjustment and operation

8. The reduction ratio of the pantograph arm can be adjusted beyond the usual values very accurately by putting slip gauge blocks between the measuring bases provided on the arms

9. The cutter spring goes up automatically by spring pressure after engraving each character, thus preventing spoiling of the job. It is also

free of vibration even at maximum speed, thus ensuring a clean and excellent surface finish of the job.

Working principal: The machine is supplied with electric motor with starter, machine lamp, foot operated start-stop switch, endless cord belt, spindle collets of 3,4,5 & 6mm size, cutter setting bar and necessary spanners. Optional access. include rough milling attachment, set of letters, rotary table etc.

COPY TABLE: THE TABLE TO THE RIGHT IS COPY TABLE HELD ON THE HORIJONTAL SIDEWAY WITH VERTICAL AND ROTATORY MOVEMENT.

WORK TABLE: THE WORK TABLE IS USED FOR HOLDING THE WORK VERTICALLY FOR ENGRAVING ON IT.IT HAS THREE DIRECTIONAL MOTION CONTROLLED BYSCREW AND INDICATING SLRVES.

CUTTING TOOL: THE CUTTER USED IN THIS MACHINE VARY FROM 3MM TO 8MM DIAMETRE.

THE CUTTING EDGE IS FORMEDBY GRINDING A ROUND STEEL ROAD TO ITS CENTRE AND THENE PUTTED THE DESIRED PROFILE AT ITS END.A SMALL CUTTER GRINDER MACHINE IS SUPPLIED SPECIALLY FOR PRODUCING THE GIVEN PROFILE TO THE CUTTER.

A selection of 5 popular tools that are used to engrave a wide range of materials.

This set of tools will familiarize you with our cutters and assist in determining which tool you prefer for the material being engraved.

Standard Conical: Most commonly used cutter for use with cnc milling machines, top loading engraving machines,

Spring Loaded Engraving Tools or industrial marking machines. Engraves and marks the widest variety of materials: plastic, brass, aluminum, metals, steel and more.

Conical Ball nose (B): Radius tip tool that produces a cut with a rounded bottom.

Testing has demonstrated that 2L Conical Ball nose tool can withstand higher cutting forces than standard Ball nose End mills or tapered Ball nose End mills. Engrave and mark: aluminum, acrylic, plastics, steels and more.

Tough Tip (T): This tool is designed to engrave steel, stainless steel, hardened steel and other hard materials. Its' unique, patent-pending design maximizes the tip strength of the tool.

Engrave and mark harder materials: stainless steel, metals, tool steel, inconel, hasteloy, hardened steel and more.

Profiler (P): Similar in design to the Standard Conical tool but with a smaller included angle for producing narrower cuts.

Use to engrave letters that run very close together and for cutting out shapes from solid sheets. Engrave and mark: plastic, brass, aluminum and more.

Micro-Profiler (P): Micro-size Profilers with smaller included angles and micro-small tip widths for miniature engraving.

Engrave materials requiring extremely small tools and for engraving letters that run very close together. Engrave and mark: plastic, brass, aluminum and more.

Engraving Mill-Drill (M): Multi-purpose tool for engraving, chamfering, spot drilling and countersinking.

Engrave and machine a wide variety of materials from hard steels to soft plastics. Reduce tool changes by using a single tool for several operations. Engrave, chamfer, countersink and spot drill: plastics, steels, aluminum, metal and more.

Burnishing (BR): This faceted tip style tool makes shallow cuts and rubs or burnishes the surface of the workpiece.

Effective when removing plating or coating to expose the metal underneath the coating. Burnish and mark: aluminum, brass, plated metals and many other materials.

Cutter Beveler (CB): Solid carbide cutter with a 0.060" diameter parallel cutting edge for cutting through materials and a side angle for simultaneously producing a 45° bevel or chamfer on the edge of the material.

Engrave, mark and bevel: steel, brass, plastic, aluminum, many materials

Diamond Tip: Used for drag and rotary engraving for many different applications.

Diamond Tip tool produces a very fine line on glass, stone, ceramic, granite, aluminum, brass, steel and more.

Parallel Cutters (PC): Cutter designed with straight edges as opposed to the standard "V" shaped cut.

The standard cutter depth is 3X the diameter up to a maximum depth of 1/2". Engrave and mark: aluminum, plastics, acrylic and more.

Pyramid (Y): Cutter with 3 cutting edges in the shape of a pyramid, often used for 3D profiling or to engrave epoxy coated pens.

Engrave and mark: aluminum, plastic, acrylic, steel and more.

Parallel Ballnose (PB): Straight edge cutter with an included full radius on the end, produces a cut with straight walls and a rounded bottom.

Extremely effective for reverse engraving acrylic and 3D engraving applications.

Engrave and mark: aluminum, plastics, acrylic and more.

Quarter Round (Q) : Similar in design to the Standard Conical tool but has an additional split perpendicular to the first split.

Engrave and mark: plastic, brass, aluminum, steel, metals and more.

SPINDLE , CUTTER HEAD: THE SPINDLE IS HELD INTO SPINDLE HEAD AND THE SPINDLE BEING DRIVEN BY A ROUND OR VEE BELT FROM A VERTICALLY MOUNTED MOTOR.THE VERTICALE MOTION BEING OBTAINED BY MOUNTING THE UNIT SO THAT IT SWING ON HORIZONTAL PIVOT

FOR TWO DIMENSIONWAL MOTION THE MACHINE MAY BE LOCKED TO PREVENT VERTICAL MOTION

BY VARYING THE POSITION OF THE CUTTER AND FOLLOWER,REDUCTION WITH IN A RANGE OF 1 TO 1.5 TO 1 TO10 MAY BE OBTAIONED

THE SPINDLE IS PROPERLY DETACHABLE FROM THE SPINDLE HEAD AND IS PROVIDED WITH INTERCHANGEABLE COLLET FOR CARRIENG THE SHANK OF THE CUTTER USED

GRINDING OF CUTTERS: For grinding of tools Versatile single lip cutter grinder is used with the conjunctions of indexing head and swivel vice.
