Ganro Rotary Tables

December 12, 2011

Manufacturers across the globe are always looking for reliable workholding devices to accommodate their manufacturing indexing and rotating requirements. CNC Indexing & Feeding Technologies has been proud to represent the complete Ganro Industrial Corp. (Golden Sun) product line of workholding rotary tables and indexers. Ganro has been producing a wide variety of workholding products to accommodate manufacturers for over 30 years. To help a company decide which table is best for its applications, it is beneficial to understand the proper use and capability of each workholding device. CNC Indexing and Feeding Technologies offers various Ganro workholding products.

Standard Rotary Tables: The sizes range from 120mm (4.72") to 800mm (31.49") in faceplate diameter and can be used as a full rotating axis incorporated into a machine's control or as indexers with Ganro's M-Mate AC servo controller. These rotary tables and indexers are all capable of being mounted in both the vertical and horizontal positions and have large thru-holes to give manufacturers maximum flexibility.

Large rotary tables: The large rotary tables are available in a range of 1000mm (40") to 2500mm (98") in faceplate diameter. They can be used as a full rotating axis incorporated into a machine's control or as indexers with Ganro's M-Mate AC servo controller. These rotary tables and indexers are all capable of being mounted in both the vertical and horizontal positions.

Rear Motor Mount: Ganro manufactures two of the most popular sized rotary tables with a rear mounted motor for smaller vertical machining centers. The rear motor mount rotary table design is available in the standard 170mm (6.69") and 250mm (9.84") faceplate diameters. As with other Ganro rotary tables, they can be used as a full rotating axis incorporated into a machine's control or as an indexer with Ganro's M-Mate AC servo controller.

CNC Indexing offers three types of Ganro standard rotary tables to accommodate a wide range of 4- and 5-axis manufacturing requirements. The standard tilt rotary table is a trunnion design with faceplate diameters ranging from 320mm (12.59") to 800mm (31.49"). This style is created to give manufacturers ample room for workholding and workpiece while providing clearance for the machine's spindle and tool.

Compact Tilt: The compact tilt rotary table design comes in faceplate sizes of 150mm (5.90"), 200mm (7.87") and 250mm (9.84") and is ideal for smaller machining centers and smaller workpieces.

Manual Tilt: The manual tilt table is designed with a full 4th axis (rotating axis) and a manual tilting axis. It is available in sizes from 200mm (7.87") to 630mm (24.80") and is ideal if a tilting axis is only occasionally required.

Horizontal Rotary Table: This rotary table design is available with table tops ranging from 400mm (15.74") to 2500mm (98.42") square. Ganro's horizontal CNC rotary tables can be used in various areas of manufacturing but are ideal for horizontal boring mill applications.

The HR Series design can be used as a full rotating axis incorporated into a machine's control or as an indexer with Ganro's M-Mate AC servo controller. They are designed for horizontal mounting only and offer high weight capacities for large workpieces.

Horizontal Index Tables: CNC Indexing offers two types of Ganro horizontal index tables for both manual and automated manufacturing processes. Both series of precision horizontal index tables use a two piece Hirth coupling design that provides superior indexing accuracy while maintaining high rigidity during heavy cutting.

CNC Index Table: The CNC Index Tables are clamped and unclamped with hydraulics and are designed to be incorporated into a machine's CNC control or operated with Ganro's M-Mate AC servo control system.

Manual Index Tables: The Manual Index Tables are clamped and unclamped pneumatically or hydraulically. Once unclamped the series is manually indexed to the desired degree and securely clamped into position.

Face Gear Rotary Tables: The Face Gear Rotary Tables are manufactured with a three piece Hirth coupling design to avoid lifting during rotation. The use of a Hirth coupling allows for the mounting of heavy loads while offering high rigidity and high accuracy. These tables are primarily used in applications incorporating a strong tailstock and a tombstone or fixture plate. It can be integrated into a machine's control or operated through Ganro's AC servo controller.

The index tables are available in four faceplate sizes (250mm, 320mm, 400mm and 500mm). Ganro rotary tables can provide a solution for rotating and indexing small workpieces to large workpieces, for vertical and horizontal applications, for 4-axis and 5-axis work and for manual and automated applications. Ganro products give manufacturers the capability of improving the manufacturing process by accessing multiple workpiece faces in one clamping. This improves workpiece accuracy and reduces manufacturing cycle times.

Related Glossary Terms

  • Rockwell hardness number ( HR)

    Rockwell hardness number ( HR)

    Number derived from the net increase in the depth of impression as the load on the indenter is increased from a fixed minor load to a major load and then returned to the minor load. The Rockwell hardness number is always quoted with a scale symbol representing the indenter, load and dial used. Rockwell A scale is used in connection with carbide cutting tools. Rockwell B and C scales are used in connection with workpiece materials.

  • boring

    boring

    Enlarging a hole that already has been drilled or cored. Generally, it is an operation of truing the previously drilled hole with a single-point, lathe-type tool. Boring is essentially internal turning, in that usually a single-point cutting tool forms the internal shape. Some tools are available with two cutting edges to balance cutting forces.

  • centers

    centers

    Cone-shaped pins that support a workpiece by one or two ends during machining. The centers fit into holes drilled in the workpiece ends. Centers that turn with the workpiece are called “live” centers; those that do not are called “dead” centers.

  • clearance

    clearance

    Space provided behind a tool’s land or relief to prevent rubbing and subsequent premature deterioration of the tool. See land; relief.

  • computer numerical control ( CNC)

    computer numerical control ( CNC)

    Microprocessor-based controller dedicated to a machine tool that permits the creation or modification of parts. Programmed numerical control activates the machine’s servos and spindle drives and controls the various machining operations. See DNC, direct numerical control; NC, numerical control.

  • fixture

    fixture

    Device, often made in-house, that holds a specific workpiece. See jig; modular fixturing.

  • milling machine ( mill)

    milling machine ( mill)

    Runs endmills and arbor-mounted milling cutters. Features include a head with a spindle that drives the cutters; a column, knee and table that provide motion in the three Cartesian axes; and a base that supports the components and houses the cutting-fluid pump and reservoir. The work is mounted on the table and fed into the rotating cutter or endmill to accomplish the milling steps; vertical milling machines also feed endmills into the work by means of a spindle-mounted quill. Models range from small manual machines to big bed-type and duplex mills. All take one of three basic forms: vertical, horizontal or convertible horizontal/vertical. Vertical machines may be knee-type (the table is mounted on a knee that can be elevated) or bed-type (the table is securely supported and only moves horizontally). In general, horizontal machines are bigger and more powerful, while vertical machines are lighter but more versatile and easier to set up and operate.
