An important development in the accurate control of manual lathes has been announced by Newall Measurement Systems at EMO 2005.

An important development in the accurate control of manual lathes has been announced by Newall Measurement Systems at EMO 2005.

The new C80 constant surface speed (CSS) digital readout, which was demonstrated for the first time at EMO 2005, is designed to extend the capability of manual lathes by providing constant cutting speeds, irrespective of the position of the cutting tool in relation to the diameter of the workpiece.

Developed in conjunction with leading lathe manufacturers, Newall's C80 is designed to provide machine builders with a CSS DRO that incorporates all of the features necessary to conform with the EN12840:2001 Safety of Machines standard.

The display is compatible with all Newall Spherosyn and Microsyn analogue linear encoders.

Using a command signal sent from the C80 to an analogue drive, the spindle speed of a lathe can be automatically varied to ensure that the ultimate speed at the cutting surface remains constant.

By compensating for the changing radial position of the tip of the cutting tool, in relation to the spindle of the lathe, a constant speed is maintained from the centre of the chuck to the outer circumference of the workpiece.

This ensures that the same level of surface finish is achieved, regardless of position.

Inputs are available for up to three Newall encoders and resolution of 1um is achievable.

A variety of fixed and adjustable mounting options provides flexibility and ensures that a wide range of machines can benefit from the addition of the C80 CSS DRO as an OEM or OEI accessory.
