Disc grinding, as it is commonly called, can be either horizontal or vertical depending on spindle orientation. Regardless, Gardner machines feature an easily automated process, with programmed head feeds and/or servo motor control. And these units provide SPC compatible electronic controls for gaging.
Single Disc Horizontal
Single disc grinders feature simple piecepart tooling, and are CBN/Diamond capable. These units remove large amounts of stock in one pass, and eliminate some lapping operations as well as the special tooling required for second-side machining.
Rotary Carrier
With rotary carrier fixtures, pieceparts are traversed in an arc across the grinding wheel. This is the second highest production method. Grinding can be accomplished by a continuous movement of the rotary carrier tooling for high production or using a servo drive for the carrier fixture, tooling can be oscillated while wheels plunge cut towards the part for lower production rates and more precise tolerances. Normally the carrier tooling is a disc with multiple opening to accommodate the piecepart periphery.
Gardner Machine Features:
Wheel support: Abrasive wheel and spindle rigidly supported by the wheelhead assembly and machine column.
Wheelfeed:
Wheelfeed system capable of precise advance of grinding wheelhead, while resisting heavy grinding thrust loads.
Work support:
Workpieces are properly and accurately supported in tooling and brought into contact with abrasive face in the most efficient manner.
Abrasive headsetting:
The angular relationship of the abrasive wheel (headsetting) are easily and quickly adjustable. The precise headsetting once set, remains fixed.
Fixtures:
Power rotated, with indexing mechanism for ease of handling and automation compatibility.
Other carrier tooling include hardened bushings for long wear life and special V-block type carriers with clamped hold-down attachments. Carriers are designed by application engineers to suit the process.
