Description

This Timesavers 12 Series belt grinding machine has a working width of 600mm, fitted with two contact roller heads suitable for grinding, light de-burring and surface finishing.

A wide belt grinder is a stationary machine which grinds the surfaces of work pieces with rotating, endless, wide & abrasive belts.

The purpose of grinding or deburring is:

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

Serviced by Timesavers UK Distributor GE Machinery  As the UK’s trusted partner for Timesavers deburring machinery, you can rely on the quality & condition of this grinding machine to deliver smooth, consistent finishing for flat components with ease.

Function

The work piece to be ground is fed into the machine at the infeed side. The conveyor belt feeds the work piece through the machine.
During conveyance the pressure rollers push the work piece against the conveyor belt. When the work piece is fed through the machine, it is
processed by the contact roller heads The contact rollers are driven by V-belts and electric motors.

The contact roller head consists of a contact roller and a tension roller around which an abrasive belt is tensioned. The tension roller is used to tension the abrasive belt and to track it by means of the oscillation. The abrasive belt is driven by the contact roller. Passing under the contact roller, the work piece is ground. Then it leaves the machine at the outfeed side.

The work piece can be ground with one or two heads in one pass. The conveyor table is adjustable in height and suitable for work pieces of different thickness.

Through the dust hood the dust which is produced during grinding is extracted.

Machine Application

• Type  of product - Flat parts
• Minimal dimensions (WxDxH) - Any size that will stay on the conveyor belt during the process
• Maximal dimensions (WxDxH) - 600mm x n/a x 125 mm
• Maximal weight - 25kg
• Type of material - Steel, stainless steel and aluminium
• Results after operation - Finished & burrs removed (all materials must be free from oil and grease)

Machine Features

Operation

• Easy operation by means of pushbuttons with light indicator on/off.
• Load meter indicates percentage of motor load, allowing full use of grinding belts and available horsepower.
• Transport Speed control
• Height Adjustment

Conveyor

• Product conveyor table is constructed of heavy plate steel. Precision-machined top mounted on four synchronized lead screws.
• Conveyor belt, super-grip profile, oil resistant driven by variable feed unit.
• Motorized table height adjustment 1 to 125 m suitable for almost every part.
• Thickness read-out in mm.

Pressure Rollers for Accurate Guiding of Parts

• Pressure 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 roller are dynamically balanced to prevent hammering-out of vital parts and preserve machine life.
• Access doors on operation side of the machine for maintenance and quick change of abrasive belts.
• Dust extraction funnel where the dust is formed to ensure cleaner, better and more consistent work.
• Brake, stops grinding head when limit switch is tripped or estop is activated.
• Main switch door lock.
• Hour counter.

Safety

• Finger protection if the hinged guard is triggered, conveyor will stop immediately.
• If a door is opened during operation, the machine will stop automatically.
• Emergency stops at infeed- and outfeed side of the machine.

 Wide abrasive belt contact roller heads (WW)

For deburring and finishing

• Contact roller - 120mm diameter made of special “flexible” vulcanized rubber with special profiled and grooved face making it suitable for deburring and finishing.
• Single speed main motor.
• Hand wheel fine adjustment for head height.
• 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 further adjust the abrasive belt.
