Mechanical buffing systems have a motor-driven shaft to which the buff wheel is applied. In addition, most machines will have a positioning mechanism, a finishing lathe, and workpiece-specific fixtures.

Positioning Mechanism: Automated buffing machines orient parts against the media by mechanical methods to duplicate or replace human motions. They rotate, oscillate, tilt, and index the wheel and/or the workpiece.

Finishing Lathe: The finishing lathe is a device located in relation to the positioning mechanism. It allows a buff wheel to contact one of more surfaces of the workpiece at predetermined locations.

Fixturing: The workpiece fixture or tooling is used to position a part during the buffing cycle. Buffing machines can incorporate single or multiple fixtures. Fixtures can also be designed to automatically reorient a workpiece during the buffing cycle.

Buffing fixtures are unique to each part being processed, although some may be adapted to an assortment of similarly shaped parts. The design of fixtures is extremely important. Unless a part can be fixtured properly at a reasonable cost, the economical utilization of finishing equipment cannot be justified.

Types of the Buffing and Finishing Machines

Buffing machines fall within three broad categories: manual, semiautomatic, and fully automated

Manual Machines

Manual buffing machines are used in low-volume applications and applications involving the buffing of extremely complex workpieces. Manual machines, when used in conjunction with the proper buff
wheel and buffing compound can be manipulated.

Semiautomatic Machines

Semiautomatic buffing machines are used in lower-volume applications where a single finishing operation is performed on a variety of parts. Initial investment and fixturing and operating costs are low. Semiautomatic finishing machines can be used with a single- or double-end lathe.

One operator can be employed to load, unload, and operate the equipment. Semiautomatic machines hold the workpiece and present it to the buff wheel. A timed cycle controls dwell and retraction. Only one fixture is required for each machine for each type of part finished. Because the machine supports the part, operator fatigue is minimized. Various types of rotation also can be performed, depending on the type of semiautomatic machine selected.

Production of semiautomatic buffing machines depends on part configuration and the degree of finishing required. By using a double-end jack with two semiautomatics, an operator can load one machine while the other is finishing a part. This can double production without increasing labor costs.

Fully Automatic Machines

Fully automatic machines are used in high-volume applications where multiple surfaces of a workpiece must be finished. The two most common types of automatic buffing machines are rotary automatic and straight-line machines.

Rotary Automatic Machines

Rotary machines have round tables with finishing heads located around the
periphery of the table. This type of machine is typically used to finish simple, round parts requiring high production. The number of finishing heads and production determine the size of the rotary.

The table of the rotary machine can move continuously or index to start, stop, dwell, and then start again, with the length of the dwell controlled by a timer. The configuration and area of the product to be finished determine which is best. Production is higher on a continuous rotary machine because the table does not stop rotating.

On an indexing rotary machine, because of the stop, dwell, and start cycle, production is lower. Parts that have surfaces that are difficult to reach and require more dwell time in certain areas may be finished on an indexing rotary machine to obtain the dwell time necessary.

On each table, there are rotating spindles on which the parts are fixtured for the finishing sequence. Rotary tables may have a greater number of fixtures than indexing tables since the production and simple configuration make it more appropriate to be run on a continuous
machine due to the ease of reaching all surfaces.

Straight Line Machines

There are various types of straight-line automatic finishing machines. Normally, linear workpieces are finished on straight-line machines. Straight-line machines also can be used to finish round parts if extremely high production is required. There is less limitation on workpiece size as with rotary equipment.

With straight-line automatic machines, finishing heads can be placed on both sides of the machine. In addition, various heads can be incorporated into the system for buffing and polishing. With rotary equipment, the outside periphery of a rotary table is used. Various types of straight-line machines include:

• Horizontal return straight line
• Narrow universal straight line
• Over and under universal straight line
• Reciprocating straight line
• Open-center universal
• The size or length of these straight-line machines can be designed and built to accommodate the desired end result; floor space is the only major limitation. Each machine normally requires only one operator for load/unload. All operations of these machines are controlled from a push-button panel located near the operator for starting, stopping, and controlling various functions.
