GMSi Group Inc. offers premium-grade surface grinders for all levels of production. Rigidity, efficiency, and accuracy are built into all models with capacities ranging from our most basic 6” x 14” table up to our double column 50” x 100”.
• One year warranty
• USA technical support and parts
• Overall tolerance: 0.0002”
• Meehanite castings
Proprietary casted machine bases and components produced to precise engineered specifications. All castings are stress relieved and machined to the tightest tolerance, using the most current techniques and methods.
The company's large high-speed precision spindles are powered by a continuous-duty Siemens AC motor. Dynamically balanced at high rpm.
Operator friendly controls in metric or inch increments. There is continued development in building the most
operator friendly machine. With the CNC models, the company offers FANUC or SYNTCE controls. Hydraulic table drive using precision screws and a double V‐slide way. CNC models are equipped with precision linear ways and ballscrews.
Optional equipment:
• Roller dresser for forming grinding wheels
• Online grinding wheel balancing system
• Variable-speed inverter for adjusting grinding wheel speed
• Magnetic separator and paper filter for coolant filtration
• Digital readout with linear scale
• Inclinable and rotary magnetic chucks
• Manual overhead dressing device
• Oil mist collector
• Coolant chillers
Related Glossary Terms
- computer numerical control ( CNC)
computer numerical control ( CNC)
Microprocessor-based controller dedicated to a machine tool that permits the creation or modification of parts. Programmed numerical control activates the machine’s servos and spindle drives and controls the various machining operations. See DNC, direct numerical control; NC, numerical control.
- coolant
coolant
Fluid that reduces temperature buildup at the tool/workpiece interface during machining. Normally takes the form of a liquid such as soluble or chemical mixtures (semisynthetic, synthetic) but can be pressurized air or other gas. Because of water’s ability to absorb great quantities of heat, it is widely used as a coolant and vehicle for various cutting compounds, with the water-to-compound ratio varying with the machining task. See cutting fluid; semisynthetic cutting fluid; soluble-oil cutting fluid; synthetic cutting fluid.
- dressing
dressing
Removal of undesirable materials from “loaded” grinding wheels using a single- or multi-point diamond or other tool. The process also exposes unused, sharp abrasive points. See loading; truing.
- grinding
grinding
Machining operation in which material is removed from the workpiece by a powered abrasive wheel, stone, belt, paste, sheet, compound, slurry, etc. Takes various forms: surface grinding (creates flat and/or squared surfaces); cylindrical grinding (for external cylindrical and tapered shapes, fillets, undercuts, etc.); centerless grinding; chamfering; thread and form grinding; tool and cutter grinding; offhand grinding; lapping and polishing (grinding with extremely fine grits to create ultrasmooth surfaces); honing; and disc grinding.
- grinding wheel
grinding wheel
Wheel formed from abrasive material mixed in a suitable matrix. Takes a variety of shapes but falls into two basic categories: one that cuts on its periphery, as in reciprocating grinding, and one that cuts on its side or face, as in tool and cutter grinding.
- tolerance
tolerance
Minimum and maximum amount a workpiece dimension is allowed to vary from a set standard and still be acceptable.
