Description

Timesavers 22 series 900 WB Deburring Machine

A wide belt grinding machine is a stationary machine tool, which grinds or deburrs work pieces by means of endless wide abrasive belts and brushes. The purpose of grinding or deburring is:

  • Elimination of burrs or radiussing edges;
  • A high-quality finish 
  • Or a combination of both 

Application

n/a x 900x50 mm

Maximalweight

72kg

Kindof material

Stainless steel, steel and aluminium

Requirements after

operation

Deburred and/or grained and/or finished and/or

brushed

Operation

  • Easy operation by means of push buttons with light indicator on/off. Load meter indicates percentage of motor load, allowing full use of grinding belts and available horsepower.
  • Transport speed control with rotary knob
  • Height adjustment.

Conveyor

  • Conveyor table constructed of heavy plate steel. Precision-machined top mounted on four synchronized screw jacks.
  • Conveyor belt, super-grip rubber profile, oil resistant.
  • Frequency variable feed unit.
  • Motorized table height adjustment 1 to 125 mm to accommodate different part thickness.
  • Digital thickness read-out in mm.
  • Hand wheel for fine adjustment.

Pressure rollers for accurate guiding of parts

  • Spring loaded pressure rollers: sets of two rollers, oil and heat resistant, plain-faced rolls to ensure positive feeding of most parts. These rollers are covered with thick high flexible rubber for spring load action.

Additional equipment

  • Main frame: fabricated of heavy steel plate properly ribbed to avoid vibration and deflection. Dynamic balancing: all high-speed rollers and contact rollers are dynamically balanced to prevent hammering-out of vital parts and preserve machine life.
  • Access doors on both sides of the machine for ease of maintenance and quick exchange of abrasive belts.
  • Dust extraction funnel where the dust is formed to ensure clean and precise work.
  • Brake, stops grinding head when limit switch is tripped or emergency stop is activated.
  • Jog switch reverse feed.
  • Electric main switch

Safety

  • Finger protection: if the hinged guard is triggered the conveyor will stop immediately. Interlock door switch: if a door is opened during operation the machine will stop automatically.
  • Set-up key with two positions: operation and maintenance.
  • Emergency stops at infeed -and outfeed side of the machine, with manual reset button.

Machine Configuration

Head 1: Wide abrasive belt contact roller head (W)

For deburring and finishing

  • Contact roller: made of special “Flexible” vulcanised rubber with special profiled grooves for surface cleaning and edge deburring and finishing. Rubber hardness is based on customer’s requirements. Hand wheel fine adjustment in height of the head with a precision of 0,01mm to change pressure or for abrasive belt thickness. The displacement can be readout on the dial indicator.
  • Outboard support: quick release bolt that locks and unlocks for quick change of abrasive belts and provides rigid support of the grinding head.
  • Grinding belt tension: air operated and activated by a switch. Air tensioning automatically compensates for belt stretch. Machine cannot be started unless belt is tensioned.
  • Grinding belt tracking: a photoelectric system automatically keeps the fast revolving abrasive belt on the head. Due to this life time of belt improves.
  • Belt trimmer: knob to correct mis-tracking of abrasive belt.
  • 2-Speed main motor.

Head 2: Brush (B)

For brush finishing

  • Scotch Brite brush: brush can rotate with and against feed direction, chosen by selector switch.
  • Hand wheel for height adjustment of the brush to compensate for brush wear and brushing pressure. The displacement can be read out on the dial indicator.
  • Quick and easy slide-out of brush: main shaft with the brush can be removed quickly for brush exchange.
  • Oscillation: 40 strokes per minute, which ensures an even wear on the brush and a good deburring result.

Function of the Machine

The work piece to be ground is fed into the machine at the infeed side of the machine. The conveyor belt feeds the work piece through the machine. During the conveyance pressure rolls press the work piece to the conveyor belt. The roller head  and brush head are driven by electrical motors and V-belts .

When the work piece is fed through the machine, it first passes the roller head. The roller head consists of a contact roller and a tension roll around which the abrasive belt runs. The tension roll is used to tension the abrasive belt and to track it by means of the oscillation system. The abrasive belt is driven by the contact roll.

Then the work piece passes the brush head.

The brush head oscillates, i. e. the brush moves side-to-side with a stroke of 10 mm. This function ensures that the work piece will be brushed evenly.

Then the work piece runs at the outfeed side out of the machine.

Selectively, a work piece can be processed by the first head, second head or with the two heads in one pass.

The conveyor table can be adjusted in height and is suitable for work pieces of different thickness. Through the dust hood the dust is extracted which occurs during grinding.
