POWERGRINDER - Sharpening Machine

Grinding Head

• Flat belt driven, speed 1910 RPM
• Motor size 2.2 kW 415V 3-phase 1420 RPM 50 Hz
• Grinding stroke variable from 10 mm to 50 mm via hand wheel adjustment.
• Grinding head oscillates on heavy duty precision ground shafts using sealed recirculating ball bearings.
• Fabric reinforced bellows protect the slide ways from grinding dust.
• Grinding head can be tilted up to 20 degrees measured on a machine cut scale.
• Feed adjustment is achieved via a hand wheel mounted on the grinding head.
• Spring applied blade steady mechanism .
• Forward stroke is gravity fed via an internal counter weight system to prevent excessive load on the grinding wheel, back stroke is powered via the drive motor.

• Electrical control panel is positioned on the front of the machine.
• Panel gives individual stop/start and running indication lights for:
  Grinding head motor
  Feed mechanical motor
  Dust extractor motor
  Automatic filter agitation
  
  
• All motors are protected by mechanical circuit breakers and thermal overload trips.
• Emergency stop button on front of panel.

Dust Extraction

• Fully shrouded grinding head and hollow shaft ventilation system for effective dust extraction.
• Extraction via high pressure fan, 2.2 kW 415 V 3-phase 2800 RPM 50 Hz
• The integral filter compartment at rear the of the machine houses a reusable filter bag and pull out tray for dust removal.
• Automatic filter bag agitation via cam system and integral motor.

Saw Mounting

• Saw mounted on side floating arbour allowing for accurate centring of saw blade to grinding wheel.
• Saw position is obtained by rotating a handle mounted at end of machine.
• Slide ways are fully protected from grinding dust by reinforced bellows.
• Saw mounting shaft is 75 mm diameter alloy steel.
• Floating arbour is 100 mm diameter alloy steel.
• Capacity for saw blade diameter range of 1400 mm to 2400 mm.

General

• Feed mechanism. Gear box 40:1 ratio motor is 4kW 415V 3-phase 1420 RPM 50 Hz.
• 35 Strokes per minute.
• Pawl stroke is variable from 10 mm to 50 mm via hand wheel adjustment.
• Pawl adjustment is independent of grinding head stroke adjustment.
• All internal linkages have been designed using sealed for life ball/roller bearings.
