US Patent:

48670200, Sep 19, 1989

Filed:

Jan 19, 1988

Appl. No.:

7/145047

Inventors:

Ronald E. Compton - Southfield MI
Bruce A. Brown - Rochester Hills MI
Donald S. Akhurst - Centerline MI
Douglas R. Myers - Utica MI
Robert W. Smith - Holly MI
Robert W. DeBruyne - Warren MI

Assignee:

The Cross Company - Fraser MI

International Classification:

B23P 2302

US Classification:

82 111

Abstract:

A method and apparatus for finishing pistons (10) and the like from foundry-turned castings during one clamping operation to provide enhanced manufacturing productivity. Separate boring and turning modules (34, 24) of the apparatus are mounted on a primary base (18) and a grooving module (54) is mounted on a secondary base (72). The modules automatically groove the ring grooves (11), turn the complex shape of the skirt (15) and bore the wrist pin bore (13) through an ordered sequence of manufacturing steps. The piston stock is mounted for rotation on headstock and tailstock assemblies (82, 84). These assemblies are carried on the secondary base (72) which is slidably mounted on the primary base for movement into operative position with respect to the boring and turning modules according to the ordered sequence. The method and system improve piston quality while reducing manufacturing costs including saving factory floor space.

Appl. No.:

6/731419

Inventors:

Ronald E. Compton - Southfield MI

Assignee:

The Cross Company - Fraser MI

International Classification:

B23B 524

US Classification:

82 18

Abstract:

A turning machine is characterized by a new and improved control and mechanism for positioning the turning tool on the head. A CNC control issues command signals for selectively positioning the tool on the head. These signals are developed from an encoder which provides the instantaneous position of the rotating part being turned and from a program in the CNC containing information about the part. A closed loop control system receives these command signals and converts same into a control current for a linear motor which is the prime mover controlling the positioning of the tool on the head. The linear motor operates a carriage on the head and the cutting tool mounts on the carriage opposite the connection of the linear motor to the carriage. The carriage is a hollow bar guided on the head by sets of rollers which are cooperatively arranged to provide yieldably forceful constraint of the bar. The rolling action of the bar on the head provides a low friction, low inertia construction enabling rapid response to CNC commands.
