PROCUNIER 33MD (01) PDF MANUAL

The 2-Spindle models provide a center distance of 1″ minimum to 4″ maximum. 3- and 4-Spindle models may be used on a 1 ½” minimum to 4 ½” maximum equally spaced bolt circle hole pattern only.

Either of the heads may be used for right or left hand without any alterations.

The gear case is prepacked with a good grade of bearing grease which should be replaced at regular intervals depending upon usage.

These heads are designed for use with our size 3 Lead Screw Tapping Units and are available with either a 1:1 or 1:2 input to output gear ratio.

NOTE: When using 1:2 ratio, the driving lead screw must be ½ pitch of the tap or twice the pitch for metric threads.

For left hand tapping, the tapping head, lead screw assembly and direction of drill press rotation, must be “left hand.”

Always use High Speed Ground Thread Taps, the proper flow of coolant for the material tapped and correct RPM recommended by your tap manufacturer.

These heads are designed for use on drill presses or drill units. They come equipped with a cover clamp which mounts to the non-rotating quill for accuracy and rigidity.

Drilling heads are available with 1:1 input to output ratio as standard, but can be obtained with 1:2 ratio if desired.

Use of High Speed Drills and a flow of the proper coolant is recommended.

Assembling these multiple spindle heads to a PROCUNIER Lead Screw Tapper is easily accomplished by the following sequence:

1. Disassemble the two cylinder caps from the lead screw tapper by removing the eight (8) screws carefully so as not to tear the two gaskets.

2. Assemble both cylinder guide housings with gaskets in place of the cylinder caps removed in step 1. Insert the eight screws (GB) but do not tighten.

3. Slide the multiple head into position on the lead screw tapper so that the guide rods and shank slide into position smoothly. Lock the lead screw chuck nut securely (series 30033, 31033 & 32033).

4. Now tighten the eight screws in the two cylinder guide housings.

5. Insert the tap and collet into the spindle and lock.

6. Adjust the spindles to the desired centers and lock in place.

Attaching these multiple drill heads to a drill press or drill unit is easily accomplished by the following procedure:

1. Drill hole in Flange (A) to accept drill press stop rod and mount together.

2. Remove the chuck taper drill chuck and mount taper shank (D) in its place. If the unit is a morse taper style, mount the taper shank (D) directly.

3. Assemble the Flange (A), Split Collar (SC), and Adapter (E) to the multiple drill head and slide it over the spindle onto the quill making sure tang on shank (D) is fully engaged with slot in adapter (E), stop rod is properly located and then tighten flange screw (B).

4. Insert the drill and collet into the spindles and lock securely. Use tang type drills over 1/16″ diameter.

5. Adjust spindles to desired location and lock Nut (Y). The complete unit may be rotated on the quill by loosening Screw (B) for greater versatility.

NOTE: 31000 (3-Spindle Head) uses same parts as 32000 (4-Spindle Head).

Series 30033, 31033 & 32033 uses lead screw assemblies series 23400 in catalog; lead screw pitch same as tap.
