84 Engineering Shop Mate 48" Belt Grinder SM-48

WHAT IS A SHOP MATE?

The Shop Mate 48” belt grinder linisher is the most compact belt grinder in the 84 Engineering line-up, but don’t let it’s size fool you! Equipped with an industrial 1.1kw (1.5hp) 3 phase motor, variable speed controller, capability to run from 1/4" up to a 10” contact wheel as well as being fully compatible with our entire range of accessories – the Shop Mate offers the versatility of the larger 72” belt grinders / linishers on the market - without the footprint.

POWER

The Shop Mate 48" belt grinder will plug into any standard 240v power socket. The included Variable Frequency Drive (VFD) / speed controller converts power to a 3-phase signal, driving the 1.1kw motor. This setup allows you to dial in the belt speed anywhere from 0 – 4800 fpm and provides maximum motor torque even at low RPM. The VFD will automatically ramp up power when under load to maintain belt speed.

ROTATING PLATEN

The Shop Mate is equipped with a multi-function rotating platen – giving you the option of a 150mm flat platen, 2” contact wheel, 3” contact wheel and slack belt out  of the box. Changing between these configurations is as simple as loosening the locking handle and spinning the platen – you don’t even have to remove the belt!

You can also opt to include our Tri platen, with more clearance on the left side and a 4" contact wheel! This option will ship without the 2 wheel platen or regular platen arm. To use small wheels with this option you will need either a standard length arm or small wheel arm.

URETHANE WHEELS

All wheels on the Shop Mate 48" belt grinder are precision CNC machined from 6061 billet aluminium and coated in our newly formulated abrasion-resistant Urethane rubber. Not only does this provide excellent drive wheel traction (the belt will never slip, regardless of how much pressure you apply), but makes for quieter operation and a superior grinding experience. The rubberised wheels even out belt discrepancies meaning you will not experience any ‘jitter’ or ‘bounce’ through the contact wheels – even when using coarse-grit grinding belts / abrasives.

STABLE TRACKING

The flat-plane tracking mechanism offers increased tracking stability and ease of adjustment over many other options available on the market. The tracking is set-and-forget - just dial in tracking with the twist of a knob and it will remain true even under heavy belt load. The flat-plane tracking also allows for minimal crown/curvature of the tracking wheel meaning your j-flex and other lighter grinding belts / abrasives won't deform over time.

IN THE BOX

In the box is a fully powder-coated and assembled grinder, a fixed work rest, a tooling arm and a rotating platen – everything you need to complete most workshop fabrication tasks, wood / metal-working projects and knife shaping, sharpening and stock removal work. If you need your grinder for specific applications or simply require more versatility, a large range of compatible attachments, work rests and contact wheels are available.
