Original Press Release:
Planomat Provides Creep Feed & Flat Surface Grinding
MIAMISBURG, OH - The Blohm Planomat, a Universal Surface and Profile grinding system from United Grinding Technologies, Inc. (UGT), has become the solution of choice for both flat surface grinding and creep feed applications. And not just because of a very attractive price/performance ratio.
Chris Stine, vice president, says the Planomat machines have built a very solid reputation. "Since their introduction a little more than five years ago," he says, "the installed based in the US has grown to 130 some machines, Much of this acceptance stems from the Planomat's versatility to address small lots and highly precise jobs, typical of tool and die and medical applications, to very high-volume runs commonly associated with the automotive, bearing and aerospace industries."
The Planomat is designed from the ground up around a modular concept platform common to all Blohm machines. The machines are assembled from base modules, including the machine bed, column, wheelhead and machine table. These modules are manufactured in batches to assure absolute quality and consistency in machine construction. Specific guideways, drives, and controls are then added to the assembled base to meet customer-specific requirements.
High-precision linear guideways in all axes consist of 6-row ball and 4-row roller bearing systems and provide stick-slip free, highly accurate positioning with minimal maintenance. The Planomat work area is entirely enclosed to fully contain high-pressure coolant.
Specifications
The grinding range is 800 mm x 400 mm to 2,000 mm x 600 mm. Table clamping area is 1,200 mm x 400 to 2,400 mm x 600 mm. Distance between table surface and spindle center is 150 mm to 700 mm, while the grinding wheel is 400 mm x 80 mm x 127 mm (optional 400 mm x 120 mm x 127 mm).
The 18 kW variable speed main spindle achieves speeds up to 6,000 rpm, standard (8,000 rpm, optional).
Axes travels: X-axis travel is 900 mm to 2,300 mm with a rapid traverse of 30 mm/min to 30,000 mm/min. Y-axis travel is 550 mm (optional 800 mm) with a rapid traverse of 4 mm/min to 3,750 mm/min. Z-axis travel is 360 mm to 560 mm with a rapid traverse of 4 mm/min to 4,000 mm/min.
Dressing
Dressing options include highly flexible CNC diamond disk dressing, ideal for short-run applications, or full form diamond roll dressing for higher-volume production operations. The diamond disk, combined with the machine CNC axis, allows operators to program any form or shape in the wheel quickly and accurately. Fast initial dressing with specific roughing tools reduces cost due to reduced wear on precision diamond tools. Both dressing options are from table units.
Additional features, such as Auto wheel balancing, compensating coolant spouts and HSK clamping spindles are optionally available.
Control
The GE Fanuc 18i is a robust and user-friendly CNC control. The color flat screen is cleanly arranged for simplified programming with menu bars, softkeys and a Windows(TM) graphic user interface. Setup is fully supported and aided by iconographics, and optional parallel operation permits programs to be entered and optimized during the grinding process. Loop interrupt cycles allow intermediate measurement. Other features include DNC capability and remote diagnostics via modem/phone line.
Although programming on the 18i is fast, easy and straightforward (no sophisticated programming expertise required), complex part geometries and grinding routines can be solved with equal ease and flexibility. Tool management of up to 50 dressing tools or grinding wheels permits quick and simple changeovers. Standard cycles and macros enable fast, simple program generation. Automatic swivel grinding angle calculation can be simulated for all contour dressing operations, eliminating potential collisions during actual dressing.
A user-friendly Siemens 840 D CNC control is also available upon request.
