Zeatz U.K. PHV - Large (350-3500mm) Horizontal / Vertical CNC Controlled Rotary Tables
Product Introduction and Design Features
The all new PHV is designed to provide all the answers to all the needs of the rotary table user.

The PHV is based on existing technology, however it has embraced the improvements in all areas of the design and manufacture of rotary table components, to provide the end user with optimum performance and safety, combined with user friendliness not found in other manufacturers products.

The PHV table has extensive new features, including high load capacities, very high accuracy combined with a large through bore. The large bore can be fitted with special adapters to provide for any location or mounting requirement. Many of these combined features are currently unavailable on our competitors products.

High accuracy wire race bearings allow the table to accept huge carrying capacities and to minimise the total run-out of the rotary table.

PHV Wire Race Bearings

The HAWE electronic pump unit supplies the hydraulic system with a continuous and level pressure of oil.

PHV Integrated Pump Unit

The table is fitted with two large diameter high accuracy wire race bearings providing huge loading capacity, the front bearing being 90% of the size of the faceplate. This also provides for extensive twisting moment characteristics. The wormshaft is of dual lead technology, providing for high precision and ongoing quality of performance.

The integral hydraulic clamping system consists of 3 dual clamping shoes (2 on the 350 and 450 models), locking the outside diameter of the wormwheel. Each clamp shoe can be individually controlled to maximise its performance. The system is fed by a specially prepared HAWE FP electric clamping pump (where fitted). The HAWE pump has been specially selected with an innovative clear tank design to monitor the oil levels. The system also incorporates all required switching and monitoring functions required by the target machine control system.

The table faceplate is designed to incorporate an optional 4 jaw independent chuck feature, this minimises the cost and maximises the working envelope of the machine (to view all the various faceplate options please click here). Should the client require a self centering or automated chuck, the faceplate can be removed to expose a standard chuck recess mount, optimising the location accuracy of the additional equipment and the large bore providing capacity for the automation equipment required by the large diameter chuck. (For all information regarding standard chucks of all sizes and types please click here)

All the PHV range is available with large or special faceplate options together with increased centre height feature.

This picture shows the PHV fitted with a four jaw independent chucking feature and a morse taper 6 centre point.

This picture shows the PHV fitted with an independent four jaw chucking feature and with the thru hole exposed.

PHV - 4 Jaw Chucking Feature + Thru Hole

A large through bore, encompassing large standard imperial and metric sizes, for use with large and lengthy components. This is combined with a main axis mounted high accuracy encoder, that can be specified to provide extreme high accuracy to better than 1 arc second, or positional control to better than 0,00001 degrees.

The table is designed to allow for the motor to be mounted on the left or right side and the casting prepared to accept the new standard clamping blocks for easy mounting of the unit to any standard table or floor plate hole spacing. The table is also fully sealed and air purged to avoid any coolant ingress.
