WARNING! - Ensure that the operator has read and understood this manual before the drilling unit is in use. - For security reasons, any modification of the drilling unit and it’s accessories, which may affect product safety, must be approved by the manufacturers technical manager. - The unit is intended for drilling, countersinking and reaming and should not be used for any other application, unless approved by the manufacturers technical manager - Always follow local security regulations regarding installation, operation and maintenance. - The drilling unit must be securely fixed and the installation...

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 will...

Description of the drilling unit The BEP 22 and BEFP 22 consists of a vane motor powered by compressed air, a pneumatic cylinder, and a closed hydraulic system. The BEF 22 and BEFP 22 has a precision chuck for extra high precision. Thanks to precision, separate and double ball bearings run-out amounts at the most to 0,01 mm (.0004 In). The total stroke length can be variably subdivided into rapid advance and working feed across the whole range (not for the BEFP). The throttle/check valve in the hydraulic system permits exact setting of the feed rate and high speed return. Type and speed: See...

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 avoid...

Attachment The use of E2 Systems monting clamps and brackets for driling units is recommended. If other way of attachment is desired attach the drilling unit according to one of the suggestions 1 or 2 below. The drilling unit can be mounted vertically or horizontally. When mounting the drilling spindle upwards the feed force can be affected if for example a multi-spindle head is used. Optional attachment should be discussed with E2's technician.

Mounting of cutting tools The following cutting tools can be used with drilling unit: Drills, shank end mills, countersinkers, reamers or broaches. The drilling unit can be fitted with either key chuck or collet chuck. Precision chuck: Precision collet chuck: Setting 1. Ensure that the FRL unit is working properly. 2. Check the oil-level indicator (10). (See Maintenance instruction) 3. The desired drilling depth is set with adjusting screw (4). One revolution on the adjusting screw is 1 mm (.039 In). Screwed in adjusting screw provides a short drilling depth and screwed out adjusting screw provides...

Description of limit switches, accessories Drilling unit BEF 22 and BEFP 22 with pneumatic limit switch The limit switch unit (micro-valves) is preset and operates independently of the set drilling depth. If the drilling depth is changed, resetting of micro-valves V3 and V4 is not necessary. 16. 3 pcs air hoses, Polyamide Ø 4/2,7 mm (5/32") and 1 pce Y-coupling. 17. 2 pcs pneumatic micro-valves (3-way), normally closed. V3 = outer micro-valve, actuated in rear spindle position = home position. V4 = inner micro-valve, actuated in front spindle position = return position. 18. 2 pcs Cams. 19. 1...

Drilling unitt BE 22 and BEF 22 with electric limit switch The limit switch unit (micro-valves) is preset and operates independently of the set drilling depth.

M1 = outer micro-switch, actuated in rear spindle position = home position. M2 = inner micro-switch, actuated in front spindle position = return position. 18. 2 pcs Cams. 19. 1 pce Actuating lever with bar. Installation and function: The limit swiches...

Example of connection with limit switch Pneumatic:

Drilling unit with automatic chip removal Function. First the drilling unit performs a partial drilling according to a preset time. The feed is then interrupted for chip removal, I e the spindle is returning quickly to the home position and then immediately starts a new partial drilling with rapid feed to the previous drilling depth, etc. The number of chip removal operations depends on the combination of working feed rate and time. When the preset drilling depth has been reached, the drilling cycle is completed and the drilling unit returns to the home position. The drilling unit must be equipped...
