Vertical saw Head :

Vertical saw Head is supported rigid induction hardened & hard crome plated & ground guide Columns. Blade tensioning is done by Manual/Hydraulically operated cylinders. Auto height sensor optimizes ideal position of blade with least down time.


Saw Feed :

Vertical saw Head up down motion is controlled by one hydraulic cylinder. Feed for various materials is regulated by temperature and pressure compensatede flow control valve. FFC valve is provided to control the cutting pressure required for various types of Material & different tensile strength and BHN.


Clamping :

Clamping of job is done by Hydraulically operated vice jaws. Fixed Vice Jaws are perpendicular to the blade. The moving vice clamps the job with sufficient work pressure. For tube cutting variable vice pressure will be provided as optional accessories.


Floating Vice Jaws :

To accommodate bend back bars. Floating vice jaw arrangement is provided for shuttle vice. This feature comes only in fully Automatic Double Column Model..


Accuracy :

Taper 0.1 mm for 100 mm. Length ± 0.2 mm


Band wheels :

Drive and driven band wheels with optimum centre distance gives smooth blade twisting force which results in excellent performance of blade.


Standard Equipments :

• Complete electrical equipment with panel board, limit switch & electric motors
• Complete hydraulic system with Yuken make DC valve.
• Coolant System with pump and piping.
• Power driven chip brush for easy chip removal from blade.
• One M42 grade bimetal blade.
• Operation tools & spanners.


Optional Equipments :

• Chip Brushes
• Roller table 1500 mm
• Bimetal Band saw blade
• Variable vice pressure
• Nesting fixture assembly for bundle cutting up to ø 35 mm polish bars.





Fully Automatic Double Column Band Saw Machines
Model DCA - 260F / DCA - 350F




Features :

  • Precise Cut Length Setting
  • Hydraulic power pack with direction control valves
  • High Productivity
  • Low Cost


Precise Cut Length Setting :

A convenient digital read out control located at the operators station provide easy selection of precise bar length requirement.The digital read out is calibrated in 0.10mm and can be repositioned without interruption to cutting cycle. Auto head elecation & quick approach.
Raising the blade higher than necessary to clear the work for the next cut waste time.Head elevation is controlled automatically and no longer requiures the operators attention.
A control device that senses the size of the work piece permits the saw head to raise just high enough so that the blade clears the work.This reduces the index cycling time significantly



Nesting Fixture :

The hydraulically operated nesting fixture is designed for high production multiple sawing of stacked polish, small rounds & tubes. The fixture consists of vertical for front fix vice & index shuttle vice.it hold the stacked bars firmly & prevents centre bars from turning


Standard Features :

  • • Hydraulic power pack with Direction Control Valves,
  • • High efficiency helical gear box of Bonfiglioli make.
  • • Stepped pulley drive with 4 steps.
  • • Digital Preset counter with Green & Red display.
  • • Indexing shuttle vice for automatic bar feeding.
  • • Automatic Machine OFF, in case of Blade Breakage.
  • • Induction Hardened & Hard chrome platted Columns with bellows.
  • • Automatic height adjustment for saw frame to save idle time.
  • • Floating Vice jaw to accomrnodate Bend bars.
  • • Power driven wire brosh for effective chip cleaning.
  • • Length setting thru Elesa Meter & Lead screw arrangernent.

Cut piece counte, Index counter :

The cutting piece counter is used to preset the number of cuts require on automatic operation. When the counter reaches the preset number the saw automatically stops.The Index counter rnakes it possible to multiply the no. Of index cycles when pieces longer than 40Ornm required.


Idle wheel motion detector :

This device not only can protect the saw blade frorn damage if the blade overloads during cutting, but also shut off the machine if the blade breaks.


Floating vice jaws :

For un- interrupted cutting cycle Float to rear fix jaw is provided to accommodate slight bend bars without sucking in auto cycle.


Variable Frequency Drive :

Variable frequency drive Facilitates to vary the blade speed infinite variable between 20-100 rneter / minute. LED Band speed tachometer also can fit on control panel to ease of corthol to operator to select the band speed. (This is optional feature).


Standard Accessories :

  • • Bimetal Bandsaw blade mounted on machine 01 No.
  • • Allen key 8, spanner set
  • • Chip Brush 02 Nos.
  • • Instructional Manual.
  • • Nesting fixture assembly for Bundle cutting
  • • Roller tab. for 1500mmlength, 1000kg load capaciry
  • • Automatic Centralized Lubrication systerm
  • • Bar exhaust control system.
  • • Variable speed blade drive with Frequency Drive VFD.
  • • Bi-metal Bandsaw blade 3920 x 34 x 1.1mm
  • • 2 Years spare kit to meet Emergency needs
  • • Chip Brush/Oil seal kit/All belts/ Carbide wear part set/Glass Fuse/ Limit switch.
