WHAT IS A GIBSON 72” BELT GRINDER?
This is our latest masterpiece offered up to satisfy the professional needs of artisan and industrial steel workers alike. The impressive list of features is complimented by its rigid construction, guaranteed to satisfy the demands of heavy-duty grinding projects.
The Gibson 72 grinder body and stand start life as 6mm Australian-made sheet steel. The components are precision laser cut before being assembled with more than 35 high-strength seam welds. Weighing in at over 85kg, the Gibson 72 is one of the most rigid and stable platforms on the grinder market. This mass and rigid construction not only ensures accuracy and perfect alignment in all grinding scenarios, but makes for a smooth, vibration-free experience.
The auxiliary components and attachments on the Gibson 72 maintain this over-engineered philosophy and premium build quality. The 40 x 40mm tooling arms, single-piece tension mechanism and over-sized tracking knob and are CNC machined from 6061 aluminium billet. The ergonomic tension handle and rotating platen-support are laser cut from 12mm plate steel, and over-sized 25mmØ tooling spigots and the platen rotating/indexing mechanism are turned from stainless steel bar, making for a bulletproof platform that will look great even after years of punishment.
Included with every Gibson is a small wheel rest, 300 x 150mm chamfered angle-adjustable work rest, small wheel idler arm, ¼”, ½”, ¾” & 1” small wheel sets and an extremely versatile rotating platen. Simply loosen the locking handle and rotate the entire platen assembly to access 7 separate grinding setups! Utilise 2 x 2”, a 3” and a 5” contact wheel, a hardened 215mm D2 platen and 3 different slack belt lengths without removing a tooling arm! For consistency and ease of setup, the platen also includes a spring-loaded indexing pin that has 12 locking positions at 30-degree intervals.
Platen support design on the Gibson 72 also allows for excellent access on either side of the platen or contact wheels for un-interrupted grinding of edges, reliefs and awkward work pieces. The in-built tilting stand allows the grinder to be used in both vertical and horizontal orientations, opening a plethora of grinding configurations and unlocking the potential of attachments such as the Small Wheel Pairs.
The 84 Engineering Gibson 72” grinder will plug into any standard 240v 10a power socket. The included Variable Frequency Drive (VFD) is encased in a custom water/dust resistant enclosure and converts power to a 3-phase signal, driving the 1.5kw (2hp) 4-pole motor. This powerhouse of a setup spins a 7” drive wheel coated with high-traction 65 Shore A urethane rubber to generate a maximum belt speed of 5000 surface feet per minute. You can hog material at an epic rate or run the belt slowly enough for fine shaping, sharpening and polishing – the infinitely variable speed controller providing maximum torque throughout the 0-5000SFM speed range.
All contact wheels on the Gibson 72” grinder are precision CNC machined from 6061 billet aluminium and coated in our newly formulated abrasion-resistant polyurethane rubber. Rubberised wheels make for quieter operation and even out belt discrepancies meaning you will not experience any ‘jitter’ or ‘bounce’ through the contact wheels – even when using coarse-grit belts.
DRIVE WHEEL TRACKING
The Gibson grinder uses a unique drive-wheel tracking system whereby the whole motor mount tilts to adjust belt alignment. This design offers superior tracking characteristics, maintaining alignment under heavy belt loads and different belt tensions
INFINITE BELT TENSIONING
Another key feature of the Gibson grinder is the adjustable tensioning mechanism. The grinder tensioning mechanism uses a combination of acetyl bushes and a cam mechanism to easily and infinitely adjust your belt tension to suit the job. Simply use the ergonomic tensioning handle to tighten or loosen the belt. This feature comes in especially handy for using slack belts, and makes belt changes a quick, single-handed operation.
As with all 84 Engineering grinders, the Gibson is compatible with their range of accessories including the popular Surface Grinder attachment. The Gibson 72" is fully assembled in a shipping crate and is tested and fine-tuned in their workshop prior to shipping.
