RECOMMENDED METHOD FOR HOLDING DRILLS IN SPINDLES

 

’

 

To properly hold drill bit in collet and reduce the chance of slippage, a flat must be ground on the shank end of the bit. The flat should be approximately 5/16” (8mm) long and the depth should be 1/3 of the bit diameter NOTE:If bit IS too largeto fit into locking insert(smaller capacity Dual Spindles do not hove insert), a square must be ground onto the shank end of the bit.

SET-UP PROCEDURE WITH OPTIONAL

HYDRAULIC CHECK

Assemble hydraulic check to mounting bracket and assemble mounting bracketto tool using washers (Y14-8) and cap screws (Y154-48).

Measuredistance from drill point to work piece - distance “Y”. Distance “X”between hydraulic check plunger and trip bracket must be less than distance “Y”to prevent damage to drill point when it approaches the work piece.

Loosenthe cap screws (Y154-48) and position hydraulic check to obtain correct setting for distance “X”.

Tighten cop screws (Y154-48)securely before operating unit. Increasethe air flow thru the FeedControl Valve marked “F”by opening two (2) full turns from closed position.This will allow drill to advancerapidly until the trip bracketcontactsplungerof hydraul- ic check.

Insert bit into spindle and into locking insert (where applicable) In- suring that one of the set screws locates squarely on the flat of the bit. Tighten collet firmly, then tighten set screws. NOTE:DONOTover- tighten collet. NOTE:Intent of set screws is only to keep bit from turn- ing in collet.

The Hydraulic FeedRateAdjustment is located at the name plate end of the Hydraulic Check Rotateextended spindle until the slot on spindle ISlocated midway betweenthe highest and the lowest settings.

Start drill unit and the drill will advance at a rapid rate until the trip bracket contacts plunger of hydraulic check.

Slowly rotatethe Hydraulic FeedRatecounter clockwise for faster feed rate or clockwise for slower feed rate.

TO CONTROLBREAKTHROUGH

Positionhydraulic check so the distance betweenthe plunger and the trip bracket (distance “X”)is lessthan the distance from the drill point to the opposite side of the work piece (distance “W’).

lSet-up of the self-feed drill unit will be the same as explained in Set-Up Procedure, page 1.
