Type 350X – Knee, Table, and Cross Feeds

Since 1964, Servo Products Company continues to be a trusted name in the power feed industry. For nearly 60 years, we have sold our innovative designs worldwide. Beginning with the original Servo Power Feed, our engineers have utilized the latest technology in each model and are now proud to announce our newest and most technologically advanced power feed – the Servo Type 350X. Our team of engineers have created our most powerful and efficient unit yet. Keeping the same compact design, we have reengineered  our internal components to increase safety and versatility while improving performance.

Below is a list of our newest innovations:

– Brushless DC motor (BLDC) provides greater efficiency and
increased reliability.
– Continual monitoring of limit switches/E-Stop status, motor
speed, voltage, and current using microprocessor technology.
– Produces a minimum of 350 inch/pounds of continuous
torque as low as 0.3 inches/minute feed rate. This unit replaces
our previous Type 140/150/200, resulting in one power feed that
can be used on all three axes.
– Shop-tested performance proves superior to the legendary
“Bridgeport” 6F/8F power feeds.
– Extremely accurate speed regulation under varying load
conditions, as well as dynamic braking for quick stops.
– Dual voltage capable with an internal connector position change
on the circuit board, plus an extremely wide input voltage range
(90vac to 145vac) and high voltage selection (195vac to 250vac),
resulting in stable operation during power fluctuations.
– Utilizes 75% less current under the same operating conditions
than the present industry standard brushed DC motor designs.
– Drive gear changed from Delrin to hard coat anodized 7075
aluminum for extreme reliability and ability to handle the high
torque loads. Safety overcurrent protection has been added to
the motor/gear drive circuit. No more stripped gears.
– The ability to easily convert the unit from a table feed to a knee
feed.
– Only power feed on the market with a safety E-Stop button.
– The limit switches no longer have line voltage (115vac)
through them, they now have5vdc which is much safer in
case of cable damage or cuts. No risk of electrical shock.
– Safety logic circuitry to prevent accidental operation after an
emergency stop, or during power up. The power feed will not
operate after the E-Stop is released if the direction handle is
either in the left or right position. The direction handle must be
returned to the neutral or off position, then the status LED will turn
from red to blue letting you know you can now operate the power
feed either right or left direction.
– The RAPID button incorporates a dual color LED that functions
as a status indicator.

The table below shows the definition of
the red LED flashing:

1 flash – Limit switch activation (left
direction)
2 flashes – Limit switch activation (right
direction)
3 flashes – E-Stop activation
4 flashes – Motor fault
5 flashes – Input power overvoltage
6 flashes – Input power undervoltage

• Semi-automated machining on Class 1 mills to 5 hp.
• Peak torque (brushless DC motor): to 740 in-lb / 83.6 NM torque.
• Intermittent torque: 575 in-lb / 65.0 NM.
• Continuous torque: 350 in-lb / 39.6 NM @ < .5 inch per minute
• Variable feed rate: .40-32 ipm / 10-813 mm/min. (table and cross); .20-16 ipm / 5-406 mm/min. (knee).
• Rapid traverse: 32 ipm / 813 mm/min. (table and cross); 16 ipm / 406 mm/min. (knee).
• Gear reduction ratio (motor to screw shaft): 72:1.
• Industry 1st safety E-Stop button with safety control logic.
• 75% more energy efficient than any current brushed DC motor.
• Advanced speed control for precision feed rates no matter what load.
• Dynamic braking for quick stops prevents any coasting.
• Ability to switch feed directions without having to pause for feed to stop.
• Helical gearing with new and improved gear, plus current monitoring microprocessor circuitry.
• Ability to switch from a table position to knee or vice versa in less than 2 minutes.
• No risk of stripping or damaging the large drive gear thanks to sophisticated electronics.
• No motor brushes requiring service or replacement, therefore no carbon dust for clean room applications.
• All this results in a much lower projected cost of ownership over a 5-year period.
• The only 2-year warranty in the industry, no other manufacturer comes close.
• Electrical: 110V, 50/60 Hz, 4.5 Amps., 220v, 50/60 Hz, 2.25 Amps (dual voltage capability with internal jumper change)
• Approximate weight: 9.3 lb. / 4.2 kg.
