ACCU-SET BALANCE TURNING TOOL

1. With H.S.S. Cutting Tool Slide

Chip Breaker provides automatic recentering of H.S.S. cutting tools.

2. With Tangi-Square Carbide Insert Slides

Square Micro-Grain carbide inserts cut tangentially, have built in chip breaker and 4 cutting edges.

3. With Rectangular Carbide Insert Slides

Rectangular carbide inserts cut tangentially for sharp, square corners and better size control and finish.

4. With Triangular Carbide Insert Slides

Triangular carbide inserts cut radially for maximum stock removal and tool life.

TO INTERCHANGE CUTTING TOOL SLIDES:

Unscrew Tool Slide Lock Screw (Pt. #10), remove tool slide, replace with desired tool slide leaving Slide Plate (Pt. #27) in position, then reinsert lock screw and proceed as per following instructions for tool slide being used. Be certain that adjusting stud is properly engaged in slide plate. Also be certain that slot in slide plate is engaged with flange of micrometer screw.

BALANCE TURNING WITH TANGI-SQUARE
CARBIDE INSERT TOOL SLIDES

(1) Install Tangi-Square Carbide Insert into slide pocket and lock in place by tightening Insert Screw (Pt. #17). Be sure pocket is free of chips and dirt.

(2) Tool slides should then be set to approximate centerline by rotating Adjusting Stud (Pt. #28) until top surfaces of cutting tools are in line with each other and on centerline of workpiece. Be sure to slightly loosen Adjusting Stud Lock Screw (Pt. #29) and Tool Slide Clamp Screw (Pt. #10) before making any adjustments and retighten them securely after adjustment is made. (Note: this centerline adjustment is only approximate and will more than likely have to be adjusted for any machine misalignment. This can only be done when tool is actually mounted and cutting on the machine.)

(3) Loosen Slide Lock Screws (Pt. #10) slightly and adjust both insert tool slides in or out equally from center to approximate diameter desired by turning Micrometer Screws (Pt. #9). Then retighten slide lock screws securely.

(4) With spindle turning advance tool into end of bar a slight distance and check diameter. Readjust tool slides in or out and up or down for cutting on center until correct diameter is obtained as per instruction (3). To simplify adjustments each line on micrometer screw equals .004" (1MM) on diameter or .002" on the side.

(5) Repeat these operations until turned diameter and cutting action is as required.

NOTE: High Top Rake Tangi-Square Inserts are available for turning stainless steel and other difficult to machine materials. Also inserts with .015" corner radius are available for special applications.

BALANCE TURNING WITH RECTANGULAR CARBIDE INSERT TOOL SLIDE

(1) Loosen Carbide Insert Clamp (Pt. #25) by turning Carbide Insert Clamp Screw (Pt. #26) and install Rectangular Carbide Insert (Pt. #18) into pocket and tighten with Insert Screw (Pt. 17) being sure pocket is free of chips or dirt. Then adjust Rectangular Chip Breaker (Pt. #19) so that it is approximately 1/16" behind leading edge of carbide insert and lock in place with clamp.

(2) All other instructions for setting are same as for the Tangi-Square tool slide.

BALANCE TURNING WITH TRIANGULAR CARBIDE INSERT TOOL SLIDE

(1) Install Triangular Carbide Insert (Pt. #21) into pocket being sure it is free of chips and dirt. Set Triangular Chip Breaker (Pt. #22) about 1/16" back from leading edge of insert and lock in place with Clamp (Pt. #25) by tightening Clamp Screw (Pt. #26).

(2) All other instructions for setting are same as for the Tangi-Square tool slides.

NOTE: Triangular Anvil (Pt. #23) should last indefinitely and need only be changed when damaged.

BALANCE TURNING WITH H.S.S. CUTTING TOOL SLIDES

(1) Sharpen the end surface only of the H.S.S. Cutting Tool (Pt. #13) at 20° angle. Since the tools are mounted at 10° in the tool slides this will produce a 10° top rake which should be satisfactory for most materials.

(2) Assemble cutting tool into Tool Slide (Pt. #2) pushing it tightly against the Chip Breaker (Pt. #15) being sure slot is free of chips or dirt. Chip breaker should be set approximately 1/16" behind leading edge of cutting tool for trial cuts.

NOTE: Very fine diameter adjustments can be made by rocking the cutting tool as follows: Loosen lower Tool Lock Screw (Pt. #14) slightly and tighten Rocker Screw (Pt. #12) against cutting tool rocking it into work.

(3) Depending on the material being machined it may be necessary to adjust the Chip Breaker (Pt. #15) back or forth until the desired cutting action is obtained.

(4) All other instructions for setting are same as for the Tangi-Square tool slide.

For best results with this or any other turning tool, the front end of the workpiece should be chamfered at 45^° to slightly below the diameter to be turned.

To simplify resetting of tool, do not cut off the last turned piece so that cutting tools can be set against the already turned diameter.
