DROs designed to maximise productivity
Acu-Rite will be demonstrating its family of ergonomically designed digital read outs along with MILLPWR, its two and half axis control system at the EMO show.
Designed to fill a currently unserved niche in the marketplace, Curtis Machine Tools has high hopes for its new Vector production grinding machine.
With an increasing trend to outsource manufacturing to lower cost centres (India, China, South America etc) where consistent quality of supply is difficult to achieve, European manufacturers now have an alternative with the cost effective VECTOR precision production grinding machine offered by Curtis Machine Tools.
The Vector has five different interchangeable workheads that can be positioned for either straight or angle approach grinding.

Millpwr 3 software and kit offer 3D machining
Millpwr 3 software and a retrofit 'kit' provide users of good quality turret millers a three-axis CNC 3D contouring capability.
The machine features a novel patented layout in which the grinding wheel guard is fixed as an integral part of the machine's structure.
The grinding wheel, dressing tool and workpiece are sealed inside the fixed guard.
Coolant and grinding fumes are extracted from the bottom of the guard direct to the coolant filtration system.
Coolant, grinding swarf and spent grinding grit are thereby kept away from the machine's slides.
When grinding aggressive materials such as carbide, diamond or ceramics this arrangement avoids TPM issues, said Curtis.
The machine has C-axis workhead option, which allows any part geometry to be ground.
Curtis said it includes, but is not limited to, plain and tapered diameter grinding, thread grinding and non-round grinding work.
* Wheel spindle - the Vector's 5.5kW servomotor driven grinding spindle accepts grinding wheels of up to 450mm diameter by 50mm wide to be used at conventional operating speeds with constant surface speed control available as an option.
For super abrasive (CBN, etc) wheels the Vector offers cutting speeds up to 80m/s.
Various dressing options include static single point or fleece diamond, rotary diamond disc or full profile roll and automatic radius dressing unit.
* Workpiece handling - An innovative loading system is in the form of a 3-axis Cartesian robot (with option for a fourth axis) and is an integral part of the machine.
In automatic operation mode, the Curtis Vector will take up less than half the floor space of a standard grinding machine equipped with an automatic loading system.
Workpiece delivery to the Vector can include standard configurations of pallet, conveyor, vibratory bowl feeder, hopper, etc.
Customised handling systems are considered.
* Applications - typical customer applications include fuel injection parts, components for automotive systems such as brakes and steering components, turbochargers, steel/tungsten carbide tool blanks, and ceramics.
