Parts

	Remove nodules from Nickel plating, plateau the surface of the stem and provide a microscopic cross-hatch pattern for lubrication retention, and do it in 4 seconds or less. The GEM System achieved production goals in less than 3 seconds cycle time.
	Reduce the surface finish on two different surfaces, on two parts per cycle, to an 8 Ra in no more than 15 seconds and provide a "High Spot Count" of less than 5. The GEM System achieved production goals in less than 8 seconds cycle time and provided a "High Spot Count" of  0 - 2.
	Reduce the plasma coated ceramic surface from "as sprayed" to a 4 to 8 Ra at the rate of one meter per minute while maintaining diameter tolerance. The GEM System achieved the desired finish and diameter toloerance at the rate of TWO meters per minute.
	Reduce the chrome build-up around the cells of a Gravure Cylinder while maintaining cell volume and provide a fine cross-hatch pattern for ink retention. The GEM System achieved all production goals and the customer currently owns FIVE GEM Systems.
	GEM developed a Plunge Centerless System for Microfinishing parts up to 6" diameter and up to 24" face length. This particular part was Microfinished using a walking beam Load/Unload device. GEM also provides Modem Interface Devices on all machines, for convenient service anywhere in the world.
	GEM developed a Center-Type Plunge System for microfinishing virtually any diameter part, with up to a 24" face, that can be supported between centers, collets, etc. These machines can be designed for any level of automation you require and also include a Modem Interface Device.
	Remove chrome plating nodules, plateau the surface and provide a fine cross-hatch scratch pattern for oil retention and long seal life. The GEM System achieved all goals and these rods are now used on virtually ALL NASCAR, CART, Formula One and Indy car shock absorbers.
	Reduce the surface finish on two different diameter and width surfaces from 6Ra to 2Ra. GEM designed a Dual Head Plunge System that automatically Microfinished both surfaces. Cpk's on the first batch of test  parts exceeded 2.00.
	These steeering components were were ground on a cylindrical grinder to 20 to 25 Ra. The specification for the final finish was 4 to 6 Ra. GEM designed a Plunge and Traverse Microfinisher which  achieved this specification in a 24 second cycle time.
	Reduce the "Hard Turned" surface of the hub to a 4 to 8 Ra, reduce the "High Spot" count to less than 10, rotate the hub in both directions and do it all in 18 seconds. The GEM System lowered the "High Spot Count" to less than 5 and provided Ra - Cpk's in excess of 2.00 in 15 second cycles.
	Provide a highly plateaued surface and create a fine cross-hatch pattern for oil retention and prolonged seal life. A GEM Dual Head Microfinishing System achieved all the production goals and has been in 3-shift operation for 8 years with less than 1% downtime.
	A major manufacturer of Office Equipment experimented with a GEM 24150 machine. After establishing finish criteria, they asked GEM to produce a custom machine to duplicate the finish. GEM developed a machine to Microfinish the customer's rolls in a "lights out" facility. The customer now has TWO machines in operation.
	A company that manufactures Automatic Manufacturing and Assembly Systems required two Microfinished surfaces on a Motor Armature Shaft. The Microfinishing had to be performed after the Amrature was wound and assembled. The Microfinishing machine could not leave any marks on the shaft and had to fit into a small area of the Assembly Line. GEM Engineers designed a modification to the Model 04150 Microfinishing System that did not damage the Armature Shaft and achieved the desired finish at the rate of 8 assemblies per minute.
	An Italian company that specializes in re-manufacturing stainless steel belts used in manufacturing Acrylic Sheet came to GEM to find a solution to their finishing problems. They were performing the final finishing process by hand and in some cases it was taking weeks to achieve the desired finish. GEM developed a mechanism for obtaining the final finish using a GEM 08150 Microfinishing Machine. The GEM process reduced their finishing time by as much as 90% and achieved the same finish time after time.
	Reduce the "as ground" finish on a chrome plated drum to a scratch-free mirror finish. By using various abrasive grades, support platens, infeed pressures and oscillation frequencies, the GEM 08150 System achieved the goals on the first attempt.
	Over the years GEM has been asked to modify our standard 04150 and 08150 machines to fit specific situations. This photo shows an  08150 machine modified to fit on the front of the spindle housing on a Waldrich Siegen Paper Mill Roll Grinder.
	A major maufacturer of computer printers came to GEM to develop a Microfinishing Process that would provide a very specific finish on their printer head carriage rods. GEM successfully developed a process that is now being required of ALL suppliers of carriage rods for this manufacturer.
	GEM was asked to design a machine that would Microfinish the inside of the housing, after plasma coating, to a uniform finish, in less than 30 seconds. GEM designed a machine that obtained the desired finish in only 9 seconds! GEM was awarded a patent for this process.
	Demonstrations of the GEM METHOD are available, FREE of charge, FOB, Youngstown, Ohio. We will document the BEFORE and AFTER finishes as well as the parameters and time consumed to achieve the final finish. All the parts in the picture at left were finished on the same machine.
	Parts that were ground to a 8 to 10 Ra had to be Microfinished to achieve a lower Ra and have a very high percentage of Bearing Area GEM designed a center-type plunge machine able to achieve < 2 Ra surface finish with a 70% to 75% Bearing Area. The Cycle time for the operation was 6 seconds.
	Over the years GEM has been asked to modify our standard 04150 and 08150 machines to fit specific situations. This photo shows a modified 04150 machine designed to fit on the front of the carriage on a South Bend Semi-Automatic Roll Grinder.
	This customer purchased our FIRST 08150 machine. They told us  that the GEM machine reduced their finishing time for Stainless Steel and Titanium Drums by over 40%. This customer was able to train 6 operators (two per shift) in less than FOUR HOURS each.
	The GEM 04150 and 08150 Retro-fit Microfinishing Machines can be easily mounted onto virtually any lathe or roll grinder. The photo at left shows an 08150 machine mounted on a "Finishmaster" for finishing copper plated cylinders for the Gravure industry.
	GEM has received international recognition! The March 1996 issue of Abrasives Magazine shows a GEM Automatic Transfer Microfinishing System in use at a major supplier of parts for the automotive industry.
	The May 1989 issue of Machine and Tool Bluebook featured an article about the advantages of the GEM 04150 Microfinisher. The article disusses the repeatablility of the finish generated by the GEM Method of Microfinishing.
