This defect occurs when the torque required to cut the thread is higher than the final torque.� Torque wrenches and most power tools can only be set to one torque setting.� Therefore they stop tightening the fastener after the torque they are set for is reached; whether or not the screw is fully tightened.� This type of defect is commonly known as a lifted head screw.� This type of defect is frequently seen in application using metal screws cutting threads into plastic, metal screws with loctite or other adhesives cured on the thread prior to fastening, and metal screws cutting threads into aluminum.

Kolver has solved this problem with the introduction of the version 2.2 software for the EDU1AE.� The new software has a new parameter "Delay Time".� When the Delay Time parameter is set to any value other than zero the unit is running at the full torque capacity and factory set RPM level of the specific PLUTO screwdriver connected to the EDU1AE controller for that time period.� During the Delay Time the torque output of the screwdriver is not limited in any way.

See the graph below for a representation of the thread cutting process:

The Delay Time feature for thread cutting applications is unique among low cost screwdrivers.� Before Kolver's introduction of this feature customers only choice was an expensive Transducer Controller system.

KolverUSA will be rolling out an entire line of NEW Screwdrivers with Brushless motors throughout Q3 & Q4 of 2009.

The first Brushless tools to be introduced are the AS Series of Clutchless "Current Control" DC-Electric Screwdrivers. The AS Series includes six (6) families of tools with unique Torque and RPM ranges; as follows:

AS Series of Brushless Screwdrivers:

Why Brushless:

• Wider Torque & RPM Range: � Because Brushless motor commutation is accomplished electronically, brushless DC motors are capable of very high speeds and torque without arcing.
• Higher Duty cycles: �Brushless motors have a lower thermal resistance and are capable of operating in a wider temperature range.
• Sophisticated motion control capabilities: �The lack of brushes allows the BRL Series to have a broad closed-loop speed range. Also, brushless motors have a higher torque to inertia ratio, high starting energies, and high breakaway torques.
• Small and lighter: �Because they have lower thermal resistance, are capable of operating in wider temperature ranges, have higher torque to inertia ratios, and have greater acceleration, smaller brushless DC motors can do the same job that their much larger counterparts would otherwise be used for. This results in an overall cost reduction.
• Cleaner & Safer: No brushes means a maintenance reduction and no brush residue contamination to bearings or the environment. There is no arcing associated with brushes, and therefore, are safer in explosive environments. Brushless DC motors are also safer in contact with fluids than brush DC motors.
• Quieter: �Because there is no brush arcing or brush commutation, brushless motors are much quieter both electrically and audibly.

The BRL series operates by setting a torque, speed, and ramp on a controller, then validating the resulting torque on a torque tester or rotary transducer. �A BR series controller, purchased separately, is required for these tool to operate.

Multi Spindle applications are popular across a wide range of assembly operations.� The solutions available in the past range from Pneumatic systems that do not provide any data feed-back to expensive Transducer controlled systems.� Until now nothing has been available in-between the two approaches to the process.

Kolver's PLUTO CA screwdrivers offer a new alternative to Multi-Spindle applications.� The PLUTO CA DC-Electric screwdrivers run off the same intelligent EDU1AE Controller as all the other Kolver PLUTO products.� The system provides for a tightening strategy to be setup that includes a RPM profile and torque setting to fit the requirements of the joint.� Joints are pass/failed based on a time window and pre-calibrated torque setting.

A new reciprocating spindle design for the PLUTO screwdrivers allows the tools to be easily deployed in Multi-Spindle applications.� The reciprocating spindle ensures all the screws are tightened simultaneously.� The control system monitors the EDU1AE Controller for each screwdriver looking for a pass/fail signal.� If one screw in the assembly fails due to the time window or torque setting not be met the entire assembly is failed.� The number of completed assemblies are counted and displayed.

Rotary Transducer Torque Tester: Introductory priced $1,995/unit

The only way to accurately set your screwdriver to a specific torque value is to calibrate the tool to the joint being tightened using a rotary transducer.� Until now, expensive torque testers with extra features were customers only option.� The Kolver Mini-KE torque tester with a rotary transducer, at a introductory price of $1,995.00 complete, offers a new price point to the market place.

The Mini-KE reads the torque output from a external rotary transducer and displays the value on its digital display. Using high performance circuitry, it displays torque values in three different units up to 221 in/lbs� (25 Nm) of torque.

Features:

• User friendly menu
• Accuracy: +/_ 0.25% of Full Scale
• Selection among Nm, kg/cm, and in/lbs
• Clockwise and counter-clockwise measurement
• Manual or automatic reset
• 9 V rechargeable battery provides 4 hours continuous operation - automatic switch-off to reduce battery consumption
• 125% transducer overload protection

RPM control is a key component to managing the moment of inertia in the screw tightening process.� Too high a speed can cause the screw to strip even when the screwdriver is set at the correct torque setting.� Starting at a slow speed and increasing speed over time helps to avoid cross threading.� RPM adjustments can be critical to the success of a screw tightening strategy.

The Kolver EDU1FR Controller's RPM and Ramp adjustment provide unique RPM profile adjustment capability in a low cost Clutch Controlled Screwdrivers.� The adjustments are made with two manual knobs on the front of the Controller.

	One for maximum speed which allows for an adjustment down to 40% of the maximum rate of your chosen screwdriver.
	The second knob adjusts the ramp of the speed.� The adjustment is from 0 - 10.� 10 being the maximum ramp of 2 seconds

Question: How do you lock the operator out from changing these adjustments on a low cost controller with manual adjusting knobs on the front?

Answer: Remove the manual adjusting knobs and replace them with tamper proof lock-out tabs P/N 100001

Recommended Procedure:

1. Remove the six mounting screws that hold the front cover plat of the EDU1FR controller in place.
2. Pull the cover plate forward about one inch.� This action will pull the adjusting knobs out of the trim pots
3. Remove the adjusting knobs from the front cover plate
4. Put the cover plate back in place and replace the six mounting screws
5. Make the appropriate RPM adjustments by using a hand screwdriver to adjust the Ramp and RPM Adjustments
6. Once the RPM profile is adjusted correctly snap tamper proof RPM lockout adjustment tabs in the holes in the controller cover.

KolverUSA is pleased to introduce the Telescoping Torque Arm, model DMFK90

The Telescoping torque arm is proving to be more versatile and less exspensive than standard Parallel and Reciprocating torque arms, while still providing enough torque absorption capability for most electro-mechanical assembly applications.

The unit is comprised of three telescopic tubes, the DMFK90 torque arm offers a unique combination of light weight and high strength. They are also extremely durable and require no maintenance. This design allows smooth, comfortable movement of the tool. It takes the weight off the arm and shoulder, absorbs the torque reaction generated by the tool, and gives a wide working area without stretching.

The telescoping arm can extend from 18" to 37" in length = 19" diameter work area

The arm is supplied with a universal tool bracket that fits all Kolver screwdrivers and a mounting bracket designed to be easly installed a on vertical upright of a work bench.

The DMFK90 torque arms are specially designed for light assembly applications using electric and pneumatic screwdrivers. Used in combination with an tool balancer they minimize the risk of RMI (repetitive motion injury) and CTS (carpal tunnel syndrome).
