TO CHECK DIFFERENCE BETWEEN CUTDOWN OF CAM LOBES:


TO CHECK DIFFERENCE BETWEEN CUTDOWN OF CAM LOBES:

Install appropriate Center Hole Adapter for size of cam being checked onto the Cam Checking Stand. 

Remove 2 knobs on Indicator Slide and move slide so that line on side of slide lines up with the stamped number equal to the largest diameter of the cam being checked and retighten knobs.

Pull Roller Slide back as far as it will go and place lead cam on center stud of Cam Checking Stand.  Release Roller Slide and set dial indicator to 0.000 at top of lobe on which “spindle to turret” distance is to be set (turn indicator on by pressing “ON/CLR” button and set to 0.000 by pressing “ON/CLR” button again.)  Then rotate cam and record “plus” or “minus” readings from this zero point to the highest point of each cam lobe.

TO COMPUTE PRESET LENGTHS:

Install “CAPS” Computer aided Preset System Disc into your IBM Compatible P.C. or “DEF” “X” into your printing calculator and then enter requested dimensions according to our separate instructions.  Computer will calculate and print out the “preset” dimensions for each tool position.

TO PREPARE TOOL LENGTH CHECKING STAND:

Push Dial Indicator out of the way and install appropriate Tool Shank Adapter for the diameter of the shank of the tool size you are using into the large hole in the Indicator Stand base.  Position it so that the longer overhang is against the 2 locating pins on the table.  Next insert the 1” Setting Block with appropriate shank dia into the center hole of the Tool Shank Adapter.  Be sure it is seated against the face of the Tool Shank Adapter.  Pull out the knob on the indicator arm and let the contact go into the second groove from the bottom of the shaft.  Then raise the indicator shank with the lift lever knob and swing indicator to center over the Setting Block.  Now lower the indicator onto the Setting Block, turn indicator on by pressing “ON/CLR” button and set to 0.0000 by pressing “ON/CLR” button again.  Remove Setting Block.  The indicator will now give readings from .000” to 6.000” in 1.000” increments by moving the indicator block from groove to groove.  Grooves are 1.000” apart.

TO PRESET TURRET TOOLS LENGTHWISE:

Slide adjustable collar over shank, position it so that face of inner ring is approximately 1/32” shorter than the desired preset location and lock securely in place.  (This allows approximately +/- 1/32” adjustment of outer collar for final setting.)

Mount turret tool with Adjustable Collar attached into the Turret Tool Checking Stand.  Rotate the outer collar until the leading edge of the tool is set to the computer specified preset length and lock in place.

Repeat this procedure for all other turret tools.

IMPORTANT:   Turret Tools must be set within the following limits to be certain that they are held securely in the turret and that they will clear the machine base.

Note:   To reduce machine set up time, turret tools should be preset in advance while machine is still 

running on previous job.

TO PRESET SWING STOP AND CROSS SLIDE TOOL GAGES:

Set the Adjustable Collars on the Cross Slide Tool Setting Gages as previously described for turret tools.  Mount into the Turret Tool Checking Stand and set to the computer specified length for each cross slide position, as well as the swing stop, and tighten the set screws.

Note:    To reduce set up time, it is recommended that a separate Cross Slide Tool Gage be preset for each cross slide position as well as the swing stop.

TO SET SWING STOP AND CROSS SLIDE TOOLS LATERALLY:

Set the “Spindle to Turret” distance with a scale as you always have.  This dimension is a reference dimension only and does not have to be precisely set since all tools are set off the turret.  However, it is a good idea to add about 3/8” to this size to allow for extra space required for the Adjustable Collars.  Rotate the turret cam until turret is at the top of the lobe on which the “spindle to turret” distance is determined.  Insert Cross Slide Tool Setting Gage for the slide being set into turret, advance slide manually towards center until tool goes past the face of the gage and then adjust sideways until it just contacts the rotating face of the setting gage and lock toolpost in place.  Remove Setting Gage from turret.

Repeat this procedure for all other cross slide tools with preset gage length set accordingly.

For setting swing stop repeat this procedure except touch front face of swing stop against the back edge of the rotating portion of the Tool Setting Gage instead of against the front face.

TO CALCULATE PRESET LENGTH OF STOP STUD FOR DIEHEADS OR RECESS TOOLS:

If you are using a tool that is activated by contacting the spindle nose guard or a clamp-on type stop ring, you must establish the distance between the face of the spindle guard or stop ring and the face of the spindle in order to calculate the preset distance for the stop stud of the tool.

TO DETERMINE SPINDLE TO STOP FACE (SPINDLE NOSE GUARD) DISTANCE:

Remove Adjustable Collar from longest Cross Slide Tool Setting Gage.  Slide Cross Slide Gage Extension on to shank pushing it all the way up against the back side of the revolving head of the gage.  Tighten side set screw and lock it in place.  Replace Adjustable Collar leaving it loose on shank.  Rotate the turret cam until turret is at the top of the lobe on which the “Spindle to Turret” distance is determined.  Insert Gage into turret and then slide it forward until Gage Extension contacts the spindle nose guard (or the projection of the clamp-on type stop ring.)  Then slide Adjustable Collar back until it contacts the face of the turret, and clamp it in this position.  Back off turret, remove gage and check its overall length on the Turret Tool Checking Stand.  

The difference between this dimension and the dimension being used as the “Spindle to Turret” distance is the “Spindle to Stop Face” distance that you will enter into the computer.

It is a good idea to permanently record this “Spindle to Stop Face” distance since this dimension is a constant and can be used for future jobs on the same machine.  (Also if you are using a clamp on type stop ring, this dimension too will be constant providing the stop ring has been pushed back as far as it will go on the spindle.)

TO SET TURRET TOOLS LENGTHWISE:

Merely insert each tool into its appropriate turret hole being sure to push it up against the collar.

Since all of the lengthwise dimensions will now be very close, the machine is ready to try out.  Note, however, that adjustable tools will have to be floated to center and turning tools, knurl tools and recess tools as well as all cross slide tools will have to be set to the proper diameter.

WARNING:

To avoid the possibility of tool crashes that can cause personal injury or damage to the tool or the machine, it is imperative that the machine be jogged through one or more cycles without the stock being fed out.  When it is certain that all tools are in their correct position, let stock feed out and cautiously allow the tools to perform their operations.

After running a sample part, final adjustment of turret tools can be made by turning the adjustable micrometer collars.  Each graduation = .001”.  Before adjusting micrometer collars, loosen turret tool shank clamp screw and pull tool out from turret so that adjustment collar can be rotated without contacting turret face.  Then loosen set screw in collar, rotate ring as required, retighten set screw and push tool against turret face, then retighten turret shank clamp screw.
