FX-18S CNC Centerless Grinder
HIGHLIGHT
- Cast iron undergoes normalization heat treatment to eliminate internal stress, allowing the grinding machine to maintain long-term thermal stability and consistent precision.
- The strong grinding force significantly reduces processing time during rough grinding.
- It is particularly advantageous for the through-feed grinding of extra-long round materials.
- Inline grinding machines enable unattended, fully automated processing, greatly increasing production output.

Machine configuration
The body and components are cast with high-grade cast iron FC-30, which is artificially normalized heat heat-treated, and then subjected to natural aging treatment. Component processing adopts YASDA, MITSUI SEIKI, TOSHIBA, ELB and other world-class equipment for one-time clamping processing, precision size up to micron level, to ensure the high precision of the basic components of the equipment.
Using Taiwan’s original spindle, SNCM-21H alloy steel, after tempering, carburizing heat treatment, and then computer-controlled cryogenic treatment, its surface hardness is up to HRC-62° above, single effective hardening layer up to 1.5mm above. The main shaft uses a dynamic pressure oil film spindle.
The adjusting wheel spindle drive is a Taiwan Delta infinite speed motor, FX-18S speed control 0-250rpm(digital control) can be set at will, adjust to the best linear speed, and when the adjusting wheel diameter changes can still maintain the same linear speed, grinding out the best products.
The servo motor is cleverly designed and installed on the adjusting wheel box and directly driven by the synchronous belt. It can hit the tilt Angle with the adjusting wheel at the same time during grinding to ensure that the two belt wheels are always parallel. It overcomes many
adverse effects caused by inertia loss and chain Angle caused by the chain multi-segment transmission of the old centerless grinder. And eliminates the need to constantly change chains and zipper springs.
Spindle automatic lubricating circulating oil (senior spindle oil 10#) and oil pressure dressing device for the same oil pump, external tank, easy to clean oil change, main shaft circulating oil is filtered through two oil filters, and equipped with pressure controllers to ensure spindle life. Cooling adopts a double circuit cooling system to ensure a constant temperature of the spindle oil.
The circuit of the whole equipment adopts the Japanese Fuji circuit system, beautiful and durable, good operation. Increase the height of the electric box, convenient operation at the same time, more conducive to the circuit system heat dissipation.
