Moore ultra-precise grinder now available
1 min read
Moore Tool Company is now offering an ultra-precise contouring jig grinder it claims to be three times more accurate than anything achieved with the best available technology today.
The Moore H-500 CPWZ jig grinder holds roundness within 0.00025 mm and linear accuracy within 0.0012 mm. Key applications include die and mould making and miniature optoelectronics manufacturing.
In beta tests, the prototype grinder equipped with a hydrostatic main spindle held roundness within better than 0.00025 mm on a 14.5 mm straight hole - best previous technology held roundness to only 0.0012 mm.
On a larger bushing made of D-2 die steel hardened to Rc 62-63 with a 37 mm centre hole, the prototype grinder held 0.000018 mm on roundness. On the basis of these prototype tests, three machines have been ordered by various Pacific Rim automotive and electronics manufacturers.
The Moore H-500 CPWZ jig grinder is a multi-axis CNC machine with continuous path contouring capability. It can tackle holes up 127 mm diameter at spindle speeds up to 175,000 rpm, depending on spindle type. Reciprocation speed at 25 mm stroke is adjustable from 2 to 190 cycles/min.
Accuracy at 10 in./min traverse speed is 0.0002 mm. It can perform both wet and dry grinding of holes and contours and operates in four axes simultaneously.
It features a hydrostatic main spindle for ultra-round holes and contours and a GE Fanuc 180i-MB CNC control with a PC front end. Programmed depth control simplifies shoulder and bottom grinding, taper grinding and wiper grinding with a formed wheel.
Key options include Renishaw part probing and automatic tool changing, automatic part loader, Moore Autosize and Autogrind real time measurement systems, flood coolant, vapour extraction and fire suppression.
