Jupiter ATI Series 5 'All in One' Grinder
The Ultimate ‘All in One’ machine. A fully automatic relief and spin grinder. With automatic traverse, indexing and in feed. All of our grinders are CE compliant and meet Health and Safety requirements for noise, vibration and airborne dust particles. A fully automatic relief and spin grinder. With automatic traverse, indexing and in feed
Precision grinding is all about achieving the best possible result and the Jupiter Series 5 ATI is precision grinding at its best – automatically. With one machine you can spin and relief grind returning cylinders and bottom blades back to the original manufacturer’s specification and you can’t get better than that.
As an automatic grinder it can be set to operate independently, allowing other tasks in the workshop to be carried out simultaneously. The cast bed provides the stability required for accurate grinding and the linear bed rails ensure accurate and smooth traverse of the grinding wheel to within 0.05mm or 2 Thou. over the width of the machine.
Operator comfort and safety is maintained with a liquid coolant to prevent airborne dust and also avoids heat distortion affecting the performance of the grinder. 360 deg electric 200kg hoist is an additional versatile tool which can be used for other heavy lifting work in the workshop.
Grind cylinders and bottom blades on the same machine in situ and out of situ without the use of jigs.
