General recommendations - Apply a system for monitoring the tool in the machine. If no such system is at hand, we recommend user/operator to frequently control the tool. To ensure that no damages occurred. Thorough review of the unit Visual control of any external damages. Ensure there is possibility to quickly turn off the motor and air-supply and run a normal cycle without tool and material (to avoid further damages at the material and unit). Listen for noise from bearings and also control the run-out at the spindle nose. If not ok, unit has to be repaired and a new control for damages...

Installation of the drilling unit This Drilling and Tapping Unit is only intended for use in machinery which applies to the Machine Directive 2006/42/EC. This Drilling and Tapping Unit is designed for normal drilling, countersinking, reaming and tapping. In applications requiring high-precision hole placement or when drilling into rounded or slanted surfaces, drill bushings must be used. To be able to use the unit, it must first be installed and fitted with control equipment. Regardless of how simple the installation is performed, the unit must be fitted with necessary protective devices to...

Attachment The use of E2 Systems monting clamps and brackets for driling units is recommended. If other way of attachment is desired the front nut as shown in the below example shall be used. The drilling unit can be mounted vertically or horizontally. When attaching the drilling spindle upwards the feed force can be affected. Optional attachment should be discussed with E2's technician. Mounting of cutting tools The following cutting tools can be used with drilling unit: Drills, core drills, shank end mills, countersinkers, reamers or broaches. The drilling unit can be fitted with either...

Setting 1. Ensure that the FRL unit is working properly. 2. The desired home position is set with adjusting nut (5). One revolution on the adjusting nut is 1 mm (.039 In). Adjusting nut (5) is locked with the locking nut in the set position. 3. The desired drilling depth is set with adjusting nut (4). One revolution on the adjusting nut is 1 mm (.039 In). Screwed down adjusting nut provides a short drilling depth and screwed up adjusting nut provides a long drilling depth. Adjusting nut (4) is locked with the locking nut in the set position. 4. The total stroke length is 50 mm (1 5/16''),...

16. 1 pce 7-pole plug, male and female, with 2 m (6.56 Ft) cable. 17. 2 pcs electric micro-switches. M1 = upper micro-switch, actuated in rear spindle position = home position. M2 = lower micro-switch, actuated in front spindle position = return position 18. 2 pcs Adjusting nuts with locking nuts. Installation and function: The limit swiches provides electrical signals in both home and return position the plug (16). The micro-switches are universally connected to a 7-pole male plug for normally closed and normally open functions and requires no internal access work. During installation,...

Maintenance instruction Daily check: - Check the air-pressure on the FRL-unit, 6 – 7 bar (87 – 101.5 Psi). Max 7 bar (101.5 Psi). - Check for any leakages of air or oil. If a leakage is detected, contact service staff. Weekly check: - Check that the oil-mist lubrication is working, approx. 1 drop/10-20 cycles. 1 drop = 15 mm3 (.000528 fl.oz. (UK), .000507 fl.oz. (US)) - Check that the drilling unit is clean. Monthly check: - Check that no abnormal play is present in the drilling spindle. - Check that external silencer is not clogged. - Check that the air filter in the FRL unit is working or...
