Clean the internal MT3 taper thoroughly with a taper wiper. Check for scoring. Running on single-phase or incorrect input voltage.
Lubrication should be done via the three oil nipples located on top of the motor unit and two on the table crank mechanisms.
The spindle is a critical feature of the S68. Unlike a keyed chuck mounted directly on a shaft, the S68 utilizes a morse taper socket. This allows for the use of morse taper drill bits or, more commonly, a morse taper arbor that holds a standard keyed drill chuck.
Vintage machines require specific lubricants. The manual lists recommended oils for the spindle bearings, splined shaft, and rack-and-pinion mechanism. Modern users often translate these to ISO 68 hydraulic oil or lithium grease. Strands S68 Drill Press Manual
Use an (A-42 or equivalent). To replace:
The Strands S68 is a legendary piece of Swedish engineering known for its durability, precision, and gear-driven power. Finding a manual for these vintage machines can be a challenge, but understanding the core operations, maintenance requirements, and safety protocols is essential for any machinist or hobbyist.
Always use a proper drift key to remove Morse taper tooling from the spindle slot. Never hammer directly on the chuck or spindle. Clean the internal MT3 taper thoroughly with a taper wiper
Because these machines are built to last for decades, many operators acquire them second-hand without the original documentation. This comprehensive guide serves as an essential reference manual for the Strands S68 drill press, covering technical specifications, installation, operation, lubrication, and troubleshooting. 1. Technical Specifications and Overview
| Interval | Task | |----------|------| | | Wipe down column and table; remove metal chips and dust. Check belt for fraying. | | Weekly | Lubricate the quill rack and pinion gear with light machine oil (ISO VG 32). | | Monthly | Apply grease to the depth stop thread. Lubricate table tilt bevel gears. Check/replace belt. | | Every 6 months | Remove motor and blow out dust from head housing. Oil the spindle pulley bearings (high-temp grease). | | Annually | Check and adjust spindle bearing preload (complex – refer to manual drawings). Clean and re-grease return spring housing. |
This content is structured to serve as a functional manual for an owner, covering identification, operation, and maintenance. Lubrication should be done via the three oil
Change the gearbox oil every 1,000 hours of operation or once a year.
Change the gearbox oil every 1,200 operating hours or once a year.
Apply a few drops of light machine oil directly to the exposed quill rack and extended spindle.
Consistent lubrication is the single most important factor in keeping a Strands drill press precise for decades. Gearbox Oil Maintenance The gears run in an oil bath inside the headstock casing.
Unlike belt-driven drill presses, the Strands S68 utilizes a geared headstock.
