Italian-made circular blade and disc grinding machinery with a rotating, tilting head and automatic grinding-wheel downfeed. Supplied by Tuckwell Machinery with Australia-wide support.
The MVM LA500 / LA700 is a specialist rotary table surface grinding machine designed for bevel grinding of circular knives and surface grinding of suitable discs, plates and flat workpieces. Its rigid construction, rotating and tilting grinding head, and automatic downfeed provide a practical solution for workshops that need repeatable circular grinding.
The LA500 accommodates bevelled circular blades up to Ø500 mm, while the LA700 extends standard blade and disc capacity to Ø700 mm. Both models combine circular knife grinding with surface-grinding capability, allowing the machine to be selected around the workpieces and finishing requirements of the workshop.
For other types of circular-knife or toothed saw-blade sharpening, explore Tuckwell's Saw Blade & Circular Knife Sharpening Machines range. The LA500/LA700 is presented here for its specific rotary-table and surface-grinding applications.
The LA500/LA700 combines two complementary grinding applications on one platform. Workholding, grinding-wheel selection and any optional equipment should be matched to the material and geometry of the workpiece.
The rotary-table arrangement can be used for surface grinding suitable discs, plates, tools and other flat workpieces. MVM also identifies meat-mincing cutters and plates as applications for this type of machine.
A rotating and tilting grinding head enables bevel grinding around the circumference of compatible circular knives and blades. The machine is suited to specialist circular-blade work rather than sharpening toothed saw blades.
The mechanical rotary chuck supports circular grinding, while optional magnetic chucks and alternative configurations are available for suitable workpieces. Tuckwell can help identify the correct holding arrangement and grinding setup.
The MVM platform combines a rigid machine structure with an adjustable grinding head, controlled rotary workholding and an automatic grinding cycle. The core machine features and optional upgrades are separated below.
MVM offers additional equipment to suit different workpiece dimensions, production requirements and holding arrangements. These options should be selected as part of the machine configuration.
Compare the two models and their key grinding capacities. Optional motor, table-speed, magnetic-chuck and special-column configurations are identified separately.

Review the manufacturer’s machine information, technical specifications and available accessories for the LA500 and LA700.
Our team can help assess your circular blades, discs and surface-grinding requirements before recommending a suitable machine and workholding setup.
Tuckwell Machinery supplies professional sharpening and industrial machinery from its Redland Bay, Queensland base, with service and technical support for the equipment we supply. Our team can help you select the LA500/LA700 configuration to suit your workshop and ongoing requirements.
Choosing a rotary table grinder involves more than selecting a blade diameter. Workpiece material, holding method, bevel geometry, surface finish, daily workload and available workshop space all influence the most suitable configuration.
Tell us about your circular blades, discs and surface-grinding requirements. We can help confirm the right model, optional equipment, current pricing and availability.
Answers to common questions about the machine’s applications, capacity, standard equipment and optional configurations.
A rotary table surface grinding machine uses a rotating workholding table and grinding wheel to produce accurate surfaces on suitable workpieces. The MVM LA500/LA700 also has a rotating and tilting grinding head, allowing it to grind bevelled circular knives as well as discs and other suitable flat workpieces.
The main difference is standard blade and disc diameter capacity. The LA500 supports bevelled circular blades up to Ø500 mm, while the LA700 extends standard capacity to Ø700 mm. Special columns are also available for larger disc-grinding applications.
Yes. MVM designed the LA500/LA700 for bevel grinding of compatible circular knives and blades, as well as surface grinding of suitable discs, plates and other workpieces. The correct workholding and grinding-wheel arrangement depends on the material and geometry.
The standard machine has a fixed-speed mechanical rotating chuck. An electronic variable-speed system covering 3–35 rpm is available upon request. Tuckwell can help confirm whether that option is required for your grinding application.
The standard grinding motor is 2.2 kW, with a 3.7 kW upgrade available upon request. The machine includes automatic grinding-wheel downfeed and a timer-controlled working cycle. PLC control with motorised wheel lifting and downfeed is also available as an option.
Let Tuckwell know the workpiece type, diameter, thickness, material, bevel or surface-finish requirements and expected grinding volume. Details of your preferred workholding and any automation requirements will help the team recommend a suitable LA500/LA700 configuration.
Yes. Tuckwell Machinery supplies and supports the machines it sells, with technician-backed advice, installation and operator training, spare-parts assistance and Australia-wide support. Contact the team to discuss the requirements of your workshop and location.
