Rotary and 4th Axis
The motorized tables included with the 4th axis kit are designed and built for machining operations that involve large forces, cutting fluids, and frequent operation. The tables are popular with machine builders, manufacturing engineers, and OEMs.
The table utilizes a direct drive principle instead of a belt drive. This approach avoids the problems of side loading on the worm screw bearing. Table motors are specially designed for operation in a metal cutting environment and are totally sealed against cutting fluids, chips, and dust. The motor mount has a sealing O-ring at the face.
The table can be mounted either in a vertical (A-axis) or horizontal (C-axis) configuration. In horizontal operation the oversized coolant channels direct the coolant to your table channels. In vertical operation the table offers flat surfaces for rigid clamping both in front and behind.
Each kit includes T-bolts, nuts, and low profile clamp bars.
Features
- Horizontal and vertical operation
- Removable 5/8” locating key
- Adjustable worm gear for backlash correction
- Pre-wired AMP CPC power connector (motorized only)
- High performance, direct drive motor (motorized only)
- Dual anti-rotation locks
- Quick release of worm gear for free rotation
The single most frequent question we receive is "How can they be so cheap?" This question is normally in the context of a comparison with models offered by Haas, Yuasa, or others where similar size tables start at $5000 to $7000. Our tables are an outstanding value where they suit the application, but they are not suitable for all applications. The Tormach rotary tables have differences which can be important in certain situations. The more significant differences are noted here.
- Premium manufacturers often quote 15 arc seconds backlash. Our tables will have 30 arc seconds of backlash. On an 8" table 30 seconds of angle amounts to 0.0006" at the outer edge of the table.
- Any table should be locked in place during heavy milling. Conventional CNC tables have integral pneumatic table locks, designed to be automatically actuated. Tormach has manually operated levers for the table locks.
- Tormach tables use hydrodynamic (oil film) bearing surfaces. There are no ball or roller bearings internal to the table.
- Tormach rotary tables move 1800 degrees per minute (5 RPM). Most servo driven tables move much faster.
