Product Introduction and Design Features

The all-new PV is designed to provide all the answers to all the needs of the rotary table user.

The PV 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 PV is faster, more accurate, more flexible in operation and carries more component weight than any other standard CNC rotary table of its size anywhere in the world.

The PV rotary table is design to accept different styles of work.  The belt drive and motor can be altered in order to customise the balance between torque and speed.

The front of the PV table can be interchanged without the need for any time-consuming and expensive backplates.  This pictures shows a standard faceplate, a 3 jaw self-centering chuck and a small tapered collet chuck.

Various Faceplate configurations on the PV range of tables

Some of the PV design features include: -

A taper cleverly located deep into the face of the table, meaning tools from the carousel of the machine can be mounted directly into the table face, saving the need for the purchase of an additional collet or chucking device. The table has a through bore allowing for long components to mount through the table body if required. The table face is also designed to DIN 6350, the standard chuck recess mount type fitting. This allows for any make of standard off the shelf chuck to locate straight onto the high accuracy spindle nose (for information regarding all chuck sizes please click here)

The main spindle is mounted in high accuracy angular contact bearings, which produce a run-out of less than 5 microns (better than P4 running accuracy).

The integral Air over Oil intensification braking system provides for massive clamping forces. These are generated from a simple low pressure air supply. This supply is also used to provide a regulated air purge facility to the motor cover and direct axis encoder, ensuring total security from coolant ingress to the fully sealed electrical compartment.

 

Customer components can be modelled within a 3D environment and introduced to the table to eliminate any possibility of dimension clashes

This pictures shows a small number of accesories that are available for immediate use with the PV rotary tables.

Accesories available for the PV range of tables

A specially developed Direct Axis encoder measurement system is mounted within the rear of the unit. The 18,000 line encoder system is the smallest of its type anywhere and provides direct positional feedback from your component. This is far the most accurate method of component positioning and is found generally on rotary products much larger than the PV.

The pneumatic connector to the main body of the table is designed to allow quick release from the PV. The unique design is also completely safe for the user as the coupling automatically shuts off the external air supply prior to the operator disconnecting.

The main drive system of the table is manufactured from a high-grade specially hardened steel. The gear set is a heavy duty Hypa-Drive gear set with a large conical worm-shaft fully meshed with the gear set across its face rather than the edge of the gear. This provides very high power of transmission, very high turning speed and high retained turning torque.

The PV is designed to fit even the smallest VMC machine, the motor cover is positioned to allow the spindle head of the machine to reach the nose of the table without the possibility of collision. The motor cover itself sits in the dead area of the machine table. No wasted space, maximum component capacity.

A range of chucks are available for the PV range of rotary tables.  These include 3 jaw, 4 jaw and power chucks of 2 and 3 jaw.  All of these products are easily fitted with either little or no machining / backplates.

160, 200 and 250mm 3 Jaw self centering chucks

The PV has all the features and functions of a "large" CNC table, its small frame disguising it's capability. The PV gives a small machine a big capacity having a large faceplate, a direct mount three jaw chuck and tapered chucking feature. The tables rotational and bearing accuracy allows the user to carry out even the smallest and most delicate of operations.
