CNC machine tool manufacturer Rollomatic Inc., Mundelein, Ill., is exhibiting several new products during the GrindTec show in Augsburg, Germany, to be held March 19-22, 2014.
One product on display is the GrindSmart 6-axis CNC grinder that is furnished with a traveling work head that can produce drills with a flute length up to 12". In addition, other solid-carbide drills and high-performance endmills can be manufactured. Features include a camera to locate coolant holes and a 6-station wheel and nozzle changer.
To reduce cycle time and operator intervention, Rollomatic's 6-axis tool grinding machines incorporate new options such as auto sticking, wheel/nozzle changing, a synchronous 20 hp grinding spindle and new software that allows production of solid-carbide drills as well as endmills with flute polishes that provide razor-sharp cutting edges up to 20mm in diameter.
Rollomatic is also showcasing a 3-axis peel grinder. The ShapeSmart NP3 is a single wheel cylindrical grinder with peel and traverse-grinding capabilities. According to the company, the peel grinder is suited for manufacturing blanks for the cutting tool industry, precision punches and other parts.
In all, Rollomatic will display the following machines in booth 5111at GrindTec:
- LaserSmart 500 Laser Cutting/Ablation Machine
- ShapeSmart NP5 Peel/Pinch Grinding Machine
- GrindSmart 528XF Long Drill Grinding Machine
- ShapeSmart NP3 Peel Grinding Machine
- GrindSmart Nano6 Super-Small Tool Grinding Machine
- GrindSmart 628XW Tool Grinding Machine
- LS-II Laser Measuring Device - VirtualGrindPro Tool Design Software.
Related Glossary Terms
- computer numerical control ( CNC)
computer numerical control ( CNC)
Microprocessor-based controller dedicated to a machine tool that permits the creation or modification of parts. Programmed numerical control activates the machine’s servos and spindle drives and controls the various machining operations. See DNC, direct numerical control; NC, numerical control.
- coolant
coolant
Fluid that reduces temperature buildup at the tool/workpiece interface during machining. Normally takes the form of a liquid such as soluble or chemical mixtures (semisynthetic, synthetic) but can be pressurized air or other gas. Because of water’s ability to absorb great quantities of heat, it is widely used as a coolant and vehicle for various cutting compounds, with the water-to-compound ratio varying with the machining task. See cutting fluid; semisynthetic cutting fluid; soluble-oil cutting fluid; synthetic cutting fluid.
- grinding
grinding
Machining operation in which material is removed from the workpiece by a powered abrasive wheel, stone, belt, paste, sheet, compound, slurry, etc. Takes various forms: surface grinding (creates flat and/or squared surfaces); cylindrical grinding (for external cylindrical and tapered shapes, fillets, undercuts, etc.); centerless grinding; chamfering; thread and form grinding; tool and cutter grinding; offhand grinding; lapping and polishing (grinding with extremely fine grits to create ultrasmooth surfaces); honing; and disc grinding.
- grinding machine
grinding machine
Powers a grinding wheel or other abrasive tool for the purpose of removing metal and finishing workpieces to close tolerances. Provides smooth, square, parallel and accurate workpiece surfaces. When ultrasmooth surfaces and finishes on the order of microns are required, lapping and honing machines (precision grinders that run abrasives with extremely fine, uniform grits) are used. In its “finishing” role, the grinder is perhaps the most widely used machine tool. Various styles are available: bench and pedestal grinders for sharpening lathe bits and drills; surface grinders for producing square, parallel, smooth and accurate parts; cylindrical and centerless grinders; center-hole grinders; form grinders; facemill and endmill grinders; gear-cutting grinders; jig grinders; abrasive belt (backstand, swing-frame, belt-roll) grinders; tool and cutter grinders for sharpening and resharpening cutting tools; carbide grinders; hand-held die grinders; and abrasive cutoff saws.
