5asic Parts of the Shaper

5ase Colu!n or Pillar Cross Rail Saddle Table Ra! Tool Head $ri6e %echanis!


9/27

5ase

The base of the shaper supports the colu!nor pillar )hich supports all the )or(in# partssuch as ra!< )or( table< dri6e !echanis!

etc. 5ase is a hea6' cast iron bod'.


10/27

Colu!n or Pillar

Pillar or 5od'=* The shaper has a colu!n)hich is a ribbed castin# of cellularconstruction. The top of the colu!n carries

the ra! slide)a's< )hilst the table slide)a'sare !achined on the front of the castin#. Thecran( and slotted lin( !echanis! that dri6esthe ra! is contained )ithin the colu!n. The

dri6in# !otor< the 6ariable speed #earbo;


11/27

Cross Rail

The cross rail carries the hori>ontal tableslide)a's and is !ounted on the 6erticalslide)a's of the colu!n. The cross rail

can be raised or lo)ered b' !eans of anele6atin# scre) in order to co!pensatefor di?erent thic( nesses of )or(. Thecross rail is a< hea6' castin# and it also

carries the table cross feed scre)to#ether )ith the pa)l and ratchetinter!ittent dri6e !echanis!.


12/27

Saddle

is #ibbed to the cross rail and supports thetable. If the table is re!o6ed< the )or( canbe bolted or cla!ped to the T*slots in front of

the saddle. Cross)ise !o6e!ent of thesaddle causes the )or( table to !o6eside)a's.


13/27

Table

,or( table is a bo; shaped castin# )ith T@otsin its upper surface and do)n one side. It alsohas a 6ee !achined in the 6ertical side to

carr' c'lindrical )or(. The )or( table isbolted to the saddle and can be !o6ed6erticall' and cross)ise )ith the help ofsaddle and cross rail.


14/27

Ra!

Ra! is a ri#idl' braced castin# and islocated on the top of colu!n. The ra! isdri6en bac( and forth in its slides b' the

slotted lin( !echanis!. The ra!contains a stro(e positionin# !echanis!and the do)nfeed !echanis!.


15/27

Tool Head

The tool head holds the tool. The tool headi!parts the tool< the necessar' 6ertical andan#ular feed !o6e!ents. The tool slide

controls the in feed of the cuttin# tool intothe )or(piece. In other )ords< it controls thedepth of cut and is adusted b' a lead scre).


16/27

Slotted "in( uic( ReturnShaper $ri6e %echanis! Slotted lin( !echanis! is 6er' co!!on in

!echanical shapers. The !echanis! is si!ple andco!pact. It con6erts the rotar' !otion of theelectric !otor and the reciprocatin# !otion of the

ra!.

Reasons for Gib

Adust!ents In General< #ibs should be adusted )ith a !ini!u!clearance on a properl' Btted bearin# is fa6orableto the for!ation of a stron# oil )ed#e or Bl!.

,hen !a(in# adust!ent< be sure that une6en

)ear has not ta(en place. That is< !o6e!ents ofthe table< ra!< and slidin# bloc( are usuall'conBned to a certain portion of the entire tra6el.

Accordin#l'< after a lon# period of ti!e< there )illbe !ore )ear in this portion than else)here. If the

#ib is adusted for the )orn portion< it )ill be ti#htfor the portion that is little used. This conditione;ists onl' after a lon# period of operation ande6entuall' re+uires reBttin#.
