Aciera F1 Milling Machine & Accessories Collectible, Swiss Made

  
Made in Switzerland circa 1950, the S/N marked on the vice is 15298. This particular machine was imported to the United States by a machinery dealer in NY in the 1950s. The machine is in perfect working order. There is a noticable backlash in the Y-axis, but the screw is still accurate.

The hand dials are marked in inches (0.0005 graduations). The X and Y axis leadscrew pitch is 0.1" per turn, and the Z axis hand dial is 0.05" per turn.

The machine is very precise, and can easily hold sub-thousandth tolerances commonly needed in watchmaking. The spindle contains a two-speed gearbox. Hi/Low gear can be selected by turning a knob on the spindle. Low-gear is 8:1 reduction, and high-gear is 1:1. The original motor recently got a coat of epoxy paint, and lube.

It is a 1/3 HP, 3300 RPM, 3PH motor. It was professionally rewired and equipped with a variable-frequency-drive (VFD) that can be powered by a 120V single-phase wall outlet (North America). The built-in circuit breaker is 3-Amp. The VFD is wired to a control pendant.

Use the pendant to Start / Stop the motor, select Foward or Reverse, and select RPM (825, 1650, 2475 or 3300). The VFD is a nice addition because there's no need to adjust the belt/pulleys in order to change RPM.

The spindle can be configured for vertical or horizontal milling as shown in the pictures. KAISER Boring Head (13/16" - 1 1/32") with W12 adapter. 0 chuck with 5/16 shank. 2X machinable W12 collet blanks.

The actual machine weighs around 120 lbs. The iron casting has 3/8-16 tapped holes on the botton side for mounting.
