Servo Power Feeds
Type 140 – Knee, Table, and Cross Feeds
- The type 140 is a half-sine wave control that gives better power and durability. It is the choice of the two types for applications on the knee of the mill
- Semi-automated machining on Class 1 mills to 3 hp.
- Peak torque (half-wave series motor): to 140 in-lb / 15.8 N×m torque
- Intermittent torque: 105 in-lb / 11.9 N×m
- Continuous torque: 90 in-lb / 10.2 N×m
- Variable feed rate: .75-25 ipm / 19-635 mm/min. (table and cross); 0-12 ipm / 0-305 mm/min. (knee).
- Rapid traverse: 35 ipm / 889 mm/min. (table and cross); 12 ipm / 305 mm/min. (knee).
- Gear reduction ratio (motor to screw shaft): 72:1.
- Helical gearing and torque limiting friction safety clutch.
- Electrical: 110V, 50/60 Hz, 2.5 Amps.
- Approximate weight: 15 lb. / 6.8 kg.
Type 150 – Table and Cross Feeds
- The type 150 is a full-sine wave control that gives better control and dynamic breaking. This is best seen in the superior finishes given at slow feed rates
- Semi-automated machining on Class 1 mills to 3 hp
- Peak torque (full-wave SCR control compound DC motor): to 150 in-lb / 17 N×m torque
- Intermittent torque: 120 in-lb / 13.6 N×m
- Continuous torque: 100 in-lb / 11.3 N×m
- Variable feed rate: .50-35 ipm / 13-889 mm/min.
- Rapid traverse: 35 ipm / 889 mm/min.
- Gear reduction ratio (motor to screw shaft): 72:1
- Smooth surface finish at speeds as low as 0.5 ipm or 13 mm/min. at full torque.
- Superior speed regulation, ramping, dynamic breaking, friction safety clutch and limiting circuit protection.
- Helical gearing and torque limiting friction safety clutch.
- Electrical: 110V, 50/60 Hz, 3 Amps.
- Approximate weight: 15 lb. / 6.8 kg.
Type 200 – Knee Feeds
- Semi-automated machining on Class 1 mills up to 5 HP
- Peak torque (half-wave series motor): to 200 in-lb / 22.6 N x m torque
- Intermittent torque: 150 in-lb / 17 N×m
- Continuous torque: 120 in-lb / 13 N×m
- Variable feed rate: .5 – 12 ipm / 13-305 mm/min. (knee)
- Rapid traverse: 15 ipm / 381 mm/min. (knee)
- Gear reduction ratio (motor to screw shaft): 72:1
- Helical gearing and torque limiting friction safety clutch
- Electrical: 110V, 50/60 Hz, 3 Amps.
- Approximate weight: 21 lb. / 6.8 kg
Note: Servo Power Feeds and limit switch assemblies are not designed or warranted to be waterproof, water-sealed, or airtight. Caution must be taken at all times to protect the unit from coolant, etc. Failure to do so may result in the warranty being voided. All Servo Power Feeds come with a one year limited warranty.
