The Okamoto L350 is a used grinding machine — also commonly referred to as a surface grinder — designed for precision flat grinding of metal workpieces. Grinding machines of this type are used across toolmaking, die and mould shops, and general engineering to produce accurate flat surfaces to tight dimensional tolerances. Okamoto is a well-established Japanese manufacturer with a long-standing reputation for precision surface grinding equipment, serving industries where close-tolerance finishing work is a core requirement.
Three units of this machine are available, all located in Portugal and offered at $3,750. The machine is built on a Meehanite die-cast construction, a material chosen for its vibration-damping properties and dimensional stability, contributing to the rigid frame that Okamoto describes as a defining feature of this design. Table movement is achieved through a belt drive, and lubrication is handled by a proven gravity-feed system. The operator controls are ergonomically positioned, with conveniently located handwheels intended to optimise comfort during use.
The magnetic chuck measures 350 × 150 mm and sits on a table with a maximum longitudinal stroke of 390 mm and a maximum cross movement of 210 mm. The table accepts a maximum load of 120 kg and features one T-slot of 17 mm width. Longitudinal feed advances 3 mm per full rotation of the handwheel, while the crossfeed handwheel delivers a fine increment of 0.005 mm per division, with a handwheel graduation of 0.02 mm, giving the operator precise control over lateral positioning.
The grinding spindle motor is rated at 1.5 kW, and the spindle runs at 3,000 rpm. The grinding wheel fitted to the machine measures 205 mm in diameter by 25 mm wide, with a bore of 31.75 mm. Maximum height capacity from a new wheel to the table surface is 362.5 mm. Total electrical connection load, including the electromagnetic chuck and cooling system, is 3 kVA.
The machine has an overall footprint of 1,526 × 1,405 mm and stands 1,727 mm tall, with a total net weight of 840 kg.
