CNC Grinder / Groover – RT3000

Heavyweight grinding and grooving in one

Purpose built to meet the needs of the global rubber roller industry, the innovative RT3000 offers grinding and grooving facilities in a single, compact machine.

Incredibly heavy duty, the pioneering design of our Grinder / Groover machines has increased the maximum component weight to an incredible, 3000kg.  There is also the potential to specify heavier weights, if required.

Designed for rubber roller production

The increased component weight capacity is achieved via a traversing wheel head in both the ‘x’ (front to back) and ‘z’ (longitudinal) axes.  This eliminates the common problem of table traverse / inertia.

Wheelhead

Heavy duty construction, with optional wheel sizes and types for flexibility – 350mm Tungsten Carbide or a 760mm Resin Bonded. 

The grinding wheel spindle is mounted in large diameter sluing ring for ease of manual indexing the turret, prior to being clamped in the operating position.  Dependant on the grinding wheel option specified, the main motor drives are 11kW to 18kW.

Workhead

For extra rigidity, the forged spindle cartridge is mounted in heavy duty bearings in a heavily ribbed headstock.

It features a 78mm bore and a 300mm, 3 jaw self-centring chuck.  It has an infinitely variable drive with a maximum of 600rpm and ‘inch’ facility to aid setting.

For components held between centres, a removable bush and 5 Morse taper adaptor also come as standard.

Tailstock

For positive taper elimination, this heavy duty unit comes complete with a unique locking mechanism.   It features a 5 Morse taper with the facility to mount a 3 jaw chuck if desired and traverses the full length of the bed to accommodate differing roller lengths.

Efficient Grinder / Groover

An advanced linear slide way system is used throughout, with the axes driven by Fanuc GE hi-torque servos through heavy duty recirculating ballscrews.

Convenient and easy to use

For ease of operation, the control system is the latest Fanuc GE Oi-D touch screen CNC controller, which utilises a user-friendly question and answer format.

A multitude of programmes have been developed and incorporated into the control.  These include:

• Parallel grinding
• Convex grinding
• Concave grinding

Plus grooving cycles, offering, among others:

• Herringbone grooving
• Chevron grooving
• Diamond pattern grooving

There is also the potential for customers to prepare programmes for their own specialist shapes and patterns, as required.

Convenient and safe

Compact and with a considerably smaller footprint than conventional machines, the RT3000 Grinder / Groover can help to maximise floor space.

Two models are available – 600 and 1250 series (designation indicates maximum diameter in mm).

Both models can be specified with full guarding if required.  This still allows auto operation plus the capability of manual operation as necessary.
