Hembrug DrillPress BoorKolom PillarDrill
Boor-kolom, Drill press, Pillar drill with adjustable speed (the small wheel on the left of the machine). This is the heavier, 3-phase (Krachtstroom), version in the metal shop; there is a lighter version in the woodarea.
Cutting wood in the metal area is fine. Cutting metal in the wood area is frowned upon. If you do so - de-grease the machine/plateau post use !
- Handle for up/down of the head. Clockwise for down; Counterclockwise for up. Do not forget to (un)tighten handle 9.
- Handle for the speed.
- Hole through which you can see the current speed. The lower number is for "speed I" the high number for 'speed 2" (they are exactly 2x apart).
- Speed switch;; 0 is off, 1 is low speed and 2 is twice as fast.
- The normal on/off switches; prevents the machine from switching on spontaneously after a power failure -and- enforce a current limit/emergency stop.
- Emergency button. Do not use as an on-off button !
- Limiters for the travel
- Small scale; which you can adjust to see the travel in mm.
- Handle to lock vertical travel.
- Keyless drill chuck (taper not yet measures)
The drill press is classed as a normal, somewhat dangerous machine: instructions strongly advised but not mandatory. It can be used any hours -- but be kind to our neighbours.
Beware that unlike the small and [Drill press / boorkolom|lighter version in the woodarea]] -- this machine will NOT stop if something gets stick - but typically ruin either the drill, your work or, if you are foolish enough to hold it by hand, your hand or other nearby body parts.
Use of safety glasses will generally be needed. The use of gloves is forbidden. It increases the risk of your glove (and with it your finger) getting twisted around the drill/rotating head.
Its main risks are flying sharp bits and body parts getting caught in something rotating or your workpiece rotating/spinning.
So clamp things well.
Speed is adjusted with the wheel.
Speeds and oil (metal)
There is a chart of speeds on the wall -- or see http://engineering.ucdavis.edu/wp-content/uploads/2013/08/lathespeeds.pdf
The larger your drill diameter - the lower the speed (Alu faster than steel faster than stainlesssteel/rvs); but limit countersinks/counterbores/stepdrills and similar `specials' to 200-300RPM.
There are three types of oil next to the machine. For most metals use the green oil.
Use the non-ferro oil if you find that the green oil stains your aluminiun/non-ferro metal (this is quite rare).
The third oil is generally not suitable to use with this drill press.
A safety relay was added; with a 4-6 amp current limiters along with an emergency stop button. Normal ground/earth wiring was added.
The current rotary switch does NOT allow for a switch-on block when in the wrong position. We need to find a replacement switch.
Likely [dalander switched]. We do not have a NC on the 'off' to prevent start when on.
