Microfinishing Machine is pneumatically operated.
Press Release Summary:
Single-station Series 140M Centerless Microfinishing Machine features vertically mounted, pneumatically operated microfinishing unit, which includes abrasive film holder, guides, and indexer. It imparts micron-level surface finishes to cylindrical, single- and multi-diameter parts up to 7 in. in length, and between 0.16-1.0 in. diameter. Oscillating tooling applies fine abrasive film to rotating workpieces for specific cycles at predetermined pressures.

Centerless Microfinishing Machine Debuts at PMTS
IMPCO Machine Tools will demonstrate its new Series 140M Centerless Microfinishing machine at PMTS Booth 145. The compact machine is designed to impart micron-level surface finishes to a wide variety of critical cylindrical, single-and multi-diameter parts, such as wrist pins, valve stems, and medical parts up to 178mm (7") in length, between 25mm and 4mm diameter (0.16-1.0"). Oscillating tooling applies fine abrasive film to rotating workpieces for specific cycles at predetermined pressures to achieve demanding surface finish specifications grinders cannot match.
"As surface finish specifications for precision parts become tighter, manufacturers will look to new processes to deliver the quality demanded by the market," said an IMPCO spokesman. "The microfinishing process is the tightest tolerance material removal process available and has proven its value in consistently achieving surface finish, geometry, and size tolerances on shaft-type parts in high-volume operations." IMPCO is a world-leading designer and builder of machines and flexible systems using microfinishing technology.
The new single-station 140M microfinishing machine from IMPCO utilizes the company's microfinishing technology with a vertically mounted, pneumatically operated microfinishing unit which includes abrasive film holder, guides and indexer.
In operation, the part is manually loaded onto drive rolls located below the abrasive film. When the doors close, coolant is started and the polishing media is lowered to contact the part. Coolant is used primarily to remove material particles from the work area. The part is then rotated for a predetermined time to complete the polishing process. After polishing, the abrasive returns to home, and used abrasive film is automatically rewound. The doors are opened, and the part is removed. A light curtain assures operator safety.
Operator interface is through a digital readout and pushbutton controls. Changeover of tooling and abrasive to process different parts is accomplished manually in a short time.
The 140M is built on a rigid frame with complete, coolant-containing guarding for dry-floor operation. Machine operation is pneumatic; hydraulics with their maintenance and heat-generation issues are eliminated, and all bearings are sealed, non-lube bearings. The compact machine takes up less than 4m2 of floor space.
