Automated Rotary Table Grinder
O.M.N. Model T.R. 450
CE MACHINE, ENTIRELY MADE IN ITALY, REFURBISHED AND COMPLIANT, COMPLETE WITH MAGNETIC CHUCK AND ACCESSORIES, USER MANUAL
This automated rotary table grinder/surface grinder comes standard with all the accessories needed to achieve extremely smooth surfaces with the utmost precision; a two-speed motor, with a gear reducer and variable speed drive, controls the rotation of the table, providing variable speeds from 2 to 17 rpm.
This wide range of options allows for targeted speeds to be programmed based on the hardness of the material. The grinding head advances rapidly, at 1 mm per revolution, using a graduated handwheel. A ratchet knob allows you to set the automatic micrometric feed rate, which can be set to 0.01, 0.02, 0.03, or 0.04 mm per pulse.
The feed rate automatically stops at zero when set to 0.01 mm per pulse. The automatic feed rate is synchronized with the table rotation speed.
This automated rotary table grinder is suitable for grinding surfaces with a maximum diameter of 460 mm and circular crown surfaces with a maximum diameter of 500 mm. The grinder's perfect alignment can be restored by adjusting the adjustment screws, ensuring high-quality results over time.
Main Features
CAST IRON BASE to maintain the machine's geometric stability over time.
THICK CHROMED CAST IRON COLUMN, protected by bellows, supported by four adjustable precision bearings, and generously sized for this type of automated rotary table grinder.
Three-phase motor, air-cooled by a double jacket, to prevent the grinding machine motor from overheating during continuous operation and to maintain a constant temperature of the crankshaft and bearings.
Hardened, ground, and dynamically balanced shaft, supported by precision ball bearings generously sized for this type of automated rotary table grinder and self-adjusting with springs to preload clearance to absorb thermal expansion.
VERTICAL TRANSLATION SCREW supported by opposing, adjustable ball bearings, with movement designed to keep the grinding wheel's working area free from obstructions and prevent dust deposits in this automated rotary table grinder model.
Metal bellows for improved protection of the grinding machine's vertical translation screw.
Opposing bronze nut nuts to compensate for any wear over time of the automated rotary table grinder's vertical translation screw.
REGISTRATION GRINDING PINS located at the base of the column, on the column support, and on the grinding wheel motor, help realign the grinding machine, achieving long-lasting, parallel surfaces.
GRINDING HANDWHEEL, supported by three bearings and engaged with the screw via a pair of helical gears, equipped with a graduated drum, supported by a thrust bearing, to program the automatic descent of the grinding wheel motor.
RATCHET KNOB, for automatic, programmable micrometric feed of 0.01 – 0.02 – 0.03 – 0.04 mm per pulse, with a zero stop if the removal rate is programmed at 0.01 mm per pulse.
GROUNDS to allow maximum use of the grinding wheel's working height and to clamp non-magnetic workpieces and accessories such as the magnetic chuck and self-centering chuck.
Low voltage controls, guard, indicator light, and all the safety and compliance requirements for this type of automated rotary table grinder.
HANDLES, SHAPES, AND DIMENSIONS of the automated rotary table grinder are designed to meet current ergonomic recommendations.
