Why at500

Absolute benchmark in total automation and advanced integrated functions

The Utita AT500 lathe in the horizontal-axis multitasking version, with lengths ranging from 2000 to 9000 mm, stands out for its impressive reliability and productivity qualities, making it a top-of-the range Utita lathe.

With easy access to the workpiece loading section, parts unloading, tool inspection, easy operation of controls on the machine, high rigidity and compact design, and with the addition of innovative accessories, this machine is the ultimate in total automation.

“X-Z” axis turning carriage complete with “Y” axis

The turning carriage features electrically welded construction, with a stabilized and normalized structure in which room has been created to assist with load equilibrium and balancing in order to ensure stability during machining processes. It comprises 3 pairs of recirculating roller bearing linear guides.

Second carriage above head “x2” — “z2”

Electrically welded, stabilized and normalized structure to deliver rigidity and stability during turning, milling and drilling processes.

Torque motor headstock

The headstock comprises a through-hole chuck spindle with ASA nose, fitted on a set of three front bearings and a pair of preloaded rear bearings with NC-driven centralized lubrication.


Feeding along the axis is achieved by means of a ball screw for lengths up to 3,000 mm (3 m), while for greater lengths it is handled mechanically with a zero-play rack and pinion system. Positioning control is monitored by means of an optical linear encoder.

Focus on high quality production

The structure has been designed to achieve outstanding goals that meet the needs of the most demanding operator. Easy access to the work area for part loading and unloading and tool inspection is combined with simple operation of the on-board controls. A fundamental element of the machine is its compact structure, which gives the lathe a high degree of rigidity, necessary both for machining with high stock removal and for high-speed finishing operations.

The range of compatible accessories, such as rotating tools, “C” axis, “Y” axis, fixed or trailing steady rests, customisable tool discs, “TILTING” tool-holding headstock and tailstock, contribute to the lathe’s move towards the most complete level of automation, making it a truly integrated turning cell.

  • The base and table form a single monolithic block in a stabilised and standardised electro-welded structure.

    It has two pairs of guides:

    • The upper ones (Z axis), of the linear recirculating roller type, are on the upper side of the bed

    • The lower ones, hardened and ground (for tailstock and steady rests), are on the bed.

  • The turning carriage (Z-X axes) consists of 2 (two) slides running on linear recirculating roller guides. (OPTIONAL “Y” AXIS) On the lower part of the carriage is a device for pulling and positioning the tailstock and the steady rests.

  • Axis movement:

    • Z axis: With ball screw or rack and pinion, with backlash compensation system

    • X and Y axes: With ball screws.

    The position control and the position measuring system are by means of pressure optical scales.

  • Spindle head with Torque Motor. The spindle, with ASA 11″ or ASA 15″ coupling, is mounted on three front and two rear preloaded bearings with long-life grease lubrication.

    It can be equipped with continuous “C” axis with Torque Motor with parking brake. (optional)
