DCDS-750CNC Dual Column, Dual Miter Band Saw

Operator Control Console
Control Console extends out beyond the safety fence and can easily be positioned for operator comfort and safety insuring hands are away from the blade at band start.

Siemens Touch Screen Panel
The touch screen workstation provides the operator with easy to access job programming along with constant monitoring of jobs while the machine is running in automatic. The work station also monitors and displays blade speed, head feed rate, and head position at all times. It automatically displays any machine errors for ease of any troubleshooting eliminating any long periods of downtime.

Saw Head Design
The saw head is mounted on linear rails which are mounted to two robust columns at a 6 degree cant. The 4 point head mounting system to the columns increases stability of the saw head allowing for increased blade life.

Direct Driven Band Drive
Drive is comprised of an electric VFD controlled motor transferring power thru a gear reduction unit directly to the drive wheel eliminating belt slippage giving positive torque to the sawblade.

Servo Driven Indexer
The indexer is positioned and driven by a servo motor driven rack and pinion system including  a rotary encoder which is known for its accuracy. Its 78.5” single stroke, which can be multiplied, decreases cycle time of the machine allowing for increased production.

Retractable Shuttle Type Index Vice
Both index vice jaws retract when the vice is opened to accommodate the movement of crooked stock increasing accuracy and repeatability.

Multiple Machine Cycles
The machine can be operated in either semi-automatic or automatic mode:

In semi-automatic mode the material is placed manually by the operator or by use of the GTO function and clamped in place. The head is placed to the desired angle thru the RTO or rotate function and locked in place. The saw band is started and the cut is completed.

In the automatic mode the operator programs the pieces to be cut in one of the 99 jobs, sets the material, and starts the cycle. The machine automatically cycles thru the parts as programmed making it a “hands free” operation.

Hydraulic Band Tension
Eliminates the possibility of over/under tightening of the band for maximum cutting rates and band life.

Flood Coolant System
Supplies coolant to the blade evenly before and after the cut creating straighter cuts and allowing longer blade life due to coolant being supplied at the tooth tip.

Modified Metered Feed System
The metered cutting feed rates are regulated by the use of a hydraulic throttle valve which is controlled by a servo motor which allows us to achieve a very precise feed rate. This rate is also monitored by the system using 2 programmable operator inputs ARP and RZP.

ARP is an operator setting which allows the machine to regulate the feed rate depending on the resistance of the material or dulling of the saw blade decreasing the chance of out of square cuts.

RZP is an operator setting allowing for the setting of optimal feed rates depending on the saw band position in the material. Rates can be automatically sped up or slowed down to decrease blade wear and increase productivity.

Saw Head Turntable
Robust saw head turntable is hydraulically driven and locked in place either thru automatic cycle programming or manually entered RTO (rotate to) function and hydraulically locked in place to prevent head drift eliminating the possibility of scrap parts.

DRO for Head Positioning
DRO's are used for head angular and height positioning. These scales are time honored and known for their rigidity and service in the sawing industry.

Full stroke Hydraulic Vices and Nesting Cylinders
Full stroke hydraulic vices insure maximum part clamping eliminating the possibility of material movement. Unique designed front vice jaws give maximum clamping pressure near the cut at all times.Variable vice pressure will prevent distortion in thin wall tubing and extrusions.

Nesting Fixtures
Vertical hold down clamp assemblies allow the operator to perform multiple piece cutting increasing productivity.

Band Wheels
Cast steel band wheels insure proper band tracking and long life.

Automatic Material Indexer Retraction
Energizing the CMU button in automatic cycle allows the indexer to retract material away from the blade. Reducing damage to the saw blade teeth
