Milling Head The milling head is a single unit, including the motor, gear box and cutter spindle. It can be mounted horizontally, or vertically by means of one of the vertical supports; these supports can swivel to left or right and one of them also tilts forwards and backwards. The machine is therefore universal in the true sense of the word. Accuracy The cutter spindle, with provision for W 12 collets and spindle inserts, is hardened and ground and runs free from play in high precision pre-loaded bearings. The feedscrews are of special steel and have a ground thread. The 3 slides have ground and scraped prismatic-section slideways and any play is taken up by tapered gib-strips. These are some of the features which permit the "toolmaker's accuracy" of /- .0.01 mm (.0004"). Work-holding Accessories The work-holding accessories, such as the plain table and, by the intermediary of the swivel support, the universal table, the rotary table, the vices and the dividing heads, are mounted on a dove-tail section on the horizontal slide, which permits their displacement along it, and also effectively doubles the horizontal traverse. Fine Feed by Feedscrew or Rapid Feed by Lever The slides may be traversed either by feedscrews or levers, dependent on the application of the machine. The changeover from one method to the other is effected by clamping or unclamping the feedscrew nuts. The graduated drums read to 0.01 mm (.0004"). Vertical Compensation by Spring The vertical slide is equipped with an adjustable compensating spring, which guarantees lightness of vertical traverse irrespective of the load on the table.
