Milling Head Details:

Milling head type VK (2 axes head)

Single spindle head - continuously turn able in 2 rotary axes. Around the headstock axis C in the range of ±180° with the possibility of mechanic indexing is 1° and around the axis B, which is perpendicular to this axis in the range of +120° to -90° with the possibility of damping in adjusted position by means of hydraulic controlled friction brake. Mechanism of turning around the headstock axis C with the indexing is a part of headstock. Mechanism of turning around the second rotary axis B is a part of spindle head and is provided by means of servomotor through gears, which compose of closed chain of gears with mechanical backlash elimination in the gears. Drive of spindle is provided by headstock through 3 couples of bevel gears.

The spindle is provided with an automatic tool clamping system by means of Belleville springs with clamping force multiplier, releasing is carried out with a hydraulic cylinder. The spindle bearings are lubricated with lifelong plastic lubricant. The spindle is provided with ISO 50 as per ČSN ISO 7388-1: 2011.

Milling head type VO (universal head)

Single-spindle head with the spindle adjustable automatically in either vertical or horizontal position – continuously revolving around the headstock axis within the range of 180o, with possibility of mechanical indexing by 1o. The drive mechanism for spindle head turning around the headstock axis

with indexing is a part of the headstock. The spindle head is also revolving around the axis inclined in the angle of 45o with respect to the headstock axis which allows automatic spindle resetting in either vertical or horizontal position or any intermediate position by 2.5o. Positioning in this axis is derived from the spindle control servo drive; the spindle part of the head is locked in gear rims in the position. The spindle drive is derived from the drive shaft of the headstock through two pairs of bevel gears. The spindle is provided with ISO 50 as per ČSN ISO 7388-1: 2011.
