Construction and Performance Features #
- All castings are stabilized and stress relieved for durability.
- Bed ways are hardened and ground to a minimum of HS-70.
- Turcite B coating is applied between the bed and carriage for smooth movement.
- Low noise operation is achieved through careful engineering.
- Foot brake pedal is included for safety.
- Built-in coolant pump and fittings are standard.
- CSS (constant surface speed control) is available for E.V.S. models upon request.
- The wide bed design enhances vibration absorption.
Lubrication System #
- Oil sight window allows for easy monitoring of oil levels.
- Pressure lubrication in the headstock ensures proper lubrication and cooling during high-speed cutting.
- Splash lubrication is used in the feed gearbox and apron.
Additional Highlights #
- The headstock housing is designed to absorb vibration and resist deflection.
- Gears are hardened and precision ground using MAAG or REISHAUER technology.
- The universal gearbox supports a wide range of inch, metric, M.P., and D.P. threads without the need for change gears.
- The apron offers integrated automatic control for longitudinal and cross feeds, as well as forward and reverse feeds. R/H or L/H wheel configuration is available upon request.
- Carriage and slide feature an anti-float backlash eliminator, safety clutch at the feed shaft, and one-shot lubrication for carriage and top slide. Dual dials are provided for inch and metric systems.
- Safety is enhanced with nylon safety gears in the end train and a shear pin in the leadscrew.
- The spindle is machined from forged alloy steel, hardened, ground, and dynamically balanced, supported by high-grade precision taper roller and ball bearings.
