Andantex USA has several product lines designed to solve applications in the Machine Tool Industry. A brief description of these lines is provided below:

Preloaded Rack & Pinion Drive Systems- DRP+/KRP+

For axis drive applications requiring high accuracy positioning on CNC machine tools, a simple rack & pinion drive may not provide the accuracy needed due to the backlash between the rack & pinion. To remove this backlash, a preloaded rack & pinion drive system is needed. This system effectively eliminates the backlash between the rack & pinion by using two pinions- one to drive the axis and one to preload the axis to eliminate the backlash. Eliminating the system backlash preserves accurate axis positioning during the transition period between acceleration/steady state and deceleration, when the rack & pinion flank contact and load reverses direction.

• Preloaded Zero Backlash Axis Drive- Twin Drive
• Traveling Gantry/Column Precision Axis Drive on Milling Machine- Dual Drive

SRP High-Tech Planetary Reducer

SRP reducers are designed to be an integrated machine sub-assembly consisting of a minimum backlash hardened & ground Redex planetary gear train, high capacity tapered roller bearing, supported ISO 9409 output flange and input flange allowing universal servo-motor mounting. SRP is the ultimate high-tech servo-reducer providing the superior torsional and radial stiffness, minimum backlash and excellent torque density required for applications in the Aerospace, Machine Tool, Automation and Robotics Industries.

• Rotary Axis Drives ( Rotary Tables ,Robot Arms, Tool Changers)
• Linear Axis Drives (Low & Zero Backlash Rack & Pinion Drives, Ball screw Drives, etc.)

Modular Rack and Pinion System

This system consists of a standard range of straight, circumferential pitch, and helical racks and pinions. The modular design permits rack lengths from 0.5 meters to 2 meters to be linked end-to-end achieving any desired travel length from standard components. Rack & pinions are available with different materials, heat treatments and quality levels to ensure the correct balance of power, precision, and price to meet application requirements.

The standard range is available in modules, M, 1.0 to 10.0 ( Diametral pitch, P25.4 to 2.54) with lengths up to 2 meters allowing loads from 1 lb. to 100,000 lbs. to be moved at speeds from 0 to 1000ft/min (5 M/s). Rack lengths up to 4 meters (2 meters with ground teeth) and modules up to 20 are available on request.

• Precision Positioning Axis Drive
• Material Feed Axis on Punch Press
• Preloaded Zero Backlash Axis Drive
• Traveling Gantry/Column Axis Drive

Machine Tool Spindle Drive Gearboxes- MSD/RAM MSD

These two-speed Machine Tool Spindle Drive gearboxes extend the constant power speed range of spindle drive motors, providing high output speeds ( 12,000 rpm) for finishing aluminum and high torque at low speeds for hogging out steel. Standard ratios are 1:1 and 3.8:1 ( reduction ratios are available up to 5:1) RAM-MSD 2 speed gearboxes augment the latest spindle drive-motor technology by providing high torque at low speed. These units mount in-line between the water-cooled motor and the spindle inside of the machine tool's ram.

• Extending Constant Power Speed Range on RAM Spindle
• Turning Center Spindle Drive with Contouring

Servo-Worm Reducers- AE

This line of servo-worm reducers was specifically developed for use with the latest servo motor technology in applications that demand precise positioning and repeatability. These applications often occur in the Material Handling, Automation, CNC Machine Tool & Robotics industries.

These reducers are available in six sizes, with ratios from 2 to 24:1 and output torque capacities to 4,400 lb.ft. The units provide an angular backlash of les than 6-arc minutes standard and 3-arc minuets on request. The lightweight modular design provides easy integration with the modular rack & pinion system.

Z-Series Spiral-Bevel Gearboxes

The Z-Series Precision Bevel Gearboxes feature Klingelnberg spiral bevel gears made of case hardened, alloy steel. These versatile units can be equipped with motor mounting flanges, labyrinth seals, and ratios up to 6:1 for continuous duty servo-requirements. Efficiency of the unit is 95-98%. Features include low backlash (3 arc-minutes), high input speeds (3,000 rpm) and HP ratings from 2HP to 540HP.
