1.1Safety Recommendations

Warning

Read and understand all safety recommendations before operating this tool. Failure to follow these instructions could result in serious injury or death.

Warning — Personal Protection

• ANSI Z87.1 approved safety glasses with side shields must be worn at all times when operating this tool.
• Hearing protection is required when operating in areas where noise levels exceed 85 dBA.
• Drilling or other use of this tool may produce hazardous fumes and/or dust. To avoid adverse health effects, utilize adequate ventilation and/or a respirator. Read the material safety data sheet of any cutting fluids or materials involved in the drilling process.
• Do not wear loose clothing, jewelry, or long hair near rotating parts. Follow good machine shop practices — rotating shafts and moving components can entangle and entrap, and may result in serious injury.

Warning — Tool Operation

• Before the tool is connected to the air supply, the throttle should be checked for proper operation (i.e., throttle valve moves freely and returns to closed position).
• Before removing a tool from service or changing drill bits, make sure the air line is shut off and drained of air. This will prevent the tool from operating if the throttle is accidentally engaged.
• Use care when handling sharp cutting tools.
• Ensure the correct collet and mandrel sizes are used.
• Maximum air pressure: 90 psig (6.2 bar) using the proper size hose. Excessive air pressure increases the loads and stresses on tool parts and drills, and may result in breakage. The installation of a filter-regulator-lubricator in the air supply line ahead of the tool is highly recommended.
• The collet and mandrel must be inserted into a properly sized pre-drilled hole before starting the tool. An improperly sized pre-drilled hole prevents the mandrel from engaging the collet and could result in slippage of the tool.
• Clean up lubricant and coolant spills immediately to prevent slip/fall hazards. Hoses must be organized and care taken to avoid tripping.

Warning — Clamping & Feed Mechanisms

Due to the number and variety of tooling applications, the user’s methods engineering departments must consider any hazards that may be associated with each specific application and provide adequate operator protection from inadvertent contact with any moving components.

The clamping and feed mechanisms of self-colleting drill motors are exposed for visibility and can move when the air supply is connected or disconnected. To avoid injury, keep fingers and hands away from these areas when handling or operating this tool.

Caution — Combustible Metal Chips

Some non-ferrous metal chips (or dusts) are combustible. Examples: Aluminum, magnesium, Titanium, and Zirconium. See the material safety data sheets for combustibility of materials drilled. Never collect spark-generating material with combustible material. Examples: Collecting both steel and aluminum or steel and titanium.

Warning — Vibration Exposure

Exposure to vibration can injure your hands and arms. Some individuals are susceptible to disorders of the hands and arms when exposed to vibration and/or tasks which involve repetitive work motions. Those individuals predisposed to vasculatory or circulatory problems may be particularly susceptible.

Caution — Ergonomic Hazards

• Repetitive work motions can cause cumulative trauma disorders such as carpal tunnel syndrome and tendinitis. These disorders develop gradually over periods of weeks, months, and years.
• Tasks should be performed so that wrists are maintained in a neutral position—not flexed, hyperextended, or turned side to side.
• Use a minimum hand grip force consistent with proper control and safe operation.
• Keep body and hands warm and dry.
• Avoid anything that inhibits blood circulation: smoking tobacco, cold temperatures, certain drugs.
• Avoid awkward postures; keep wrists as straight as possible.
• Interrupt work, alternate activities, or rotate jobs to provide periods free from repetitive work motions.
• Any user suffering from prolonged symptoms of tingling, numbness, blanching of fingers, clumsiness, or weakened grip should not ignore these symptoms and should consult a physician.

2Introduction & Tool Overview

2.1General Information

The Q-matic nut plate drill motor has been developed for drilling and countersinking the two holes required for attachment of nut plate fasteners. Utilizing an air/hydraulic feed control piston system, an expanding collet grips the work with 240 lbs holding force during the complete drilling and countersinking operation.

Each Q-matic nut plate drill can be used to drill holes for all three types of nut plate fasteners: single wing, double wing, and Mickey Mouse. By simply changing the front bearing support block, lift finger, and pressure foot, one tool can be used for all types of nut plate fasteners. This eliminates the need for a specific tool to drill and countersink the various nut plate configurations.

2.3Major Tool Component Nomenclature

Major Tool Component Nomenclature

2.4Depth Control

Individual spindle adjustment knobs located at the rear of the tool control countersink depth accuracy within ±0.001″ (0.0254 mm).

Depending upon the hardness of the material being drilled, drilling cycle time can be adjusted from 1.5 seconds to 34 seconds by means of an externally mounted feed control valve.

The Q-matic nut plate drill is available in two geared speed models: 600 RPM and 6,000 RPM. An adjustable throttle control valve located in the handle enables the tool spindle speed to be reduced as much as 50%, allowing the tool RPM to be matched to the material being drilled for optimum drill bit life.

An optional externally mounted pneumatic booster pump is available for use on the 600 RPM models. This pump increases both thrust and clamping force by as much as two and one-half times.

2.5Tool Start-Up

The Q-matic nut plate drill motor is shipped from the factory equipped to the customer’s specifications: spindle RPM, nut plate styles, drill spindle spacing, and optional booster pump (if needed). Collets and mandrels can be supplied for customers with start-up nut plate drilling applications.

After unpacking, examine the customer-specified equipment on the Q-matic tool to verify the style and size of components.

Attach the air line to the 1/4″ NPT inlet bushing. 1/4″ quick disconnect plugs are the minimum recommended size for standard units and 3/8″ quick disconnect fittings are the minimum recommended size for units with booster pumps. The recommended air hose size is 3/8″ inside diameter equipped with an in-line filter and lubricator.

With the air line attached, pull the trigger to start the tool and allow it to run through a full cycle with drills in the fully extended position. When the trigger is released, drills return to the original position and the collet extends to the open position.

To adjust depth of countersink, turn the spindle adjusting knobs at the rear of the tool to the appropriate depth. Turning the knobs counterclockwise reduces depth; clockwise increases depth.

Testing the tool on a separate piece of material will ensure that the tool is operating properly and that the countersink depth has been accurately set.

2.6Tool Operation

Use a conventional drill to drill the pilot hole in the material. The size of this pilot hole should match the diameter of the collet and mandrel selected for the tool.

Insert the collet in the pilot hole while holding the pressure foot firmly against the surface to be drilled, and actuate the trigger. The mandrel will retract and clamp the tool firmly against the work while the two drills begin feeding into the material.

The drilling cycle is complete when the drills have reached the maximum pre-set depth. Releasing the trigger will cause the drills to retract and the collet to release. The tool is now ready to begin another cycle.

3Major Component Disassembly
