PRECISION SPINDLE

The spindles are Made from Japanese high-grade alloy steel (SNCM-220H), carburized heat treated, then the spindle proceed to sub zero treatment, finally finished after precision machining & grinded.

Inner hardness HRC25 ° ~30 ° , surface hardness HRC62 ° to feature spindle with high torque load, deformation free, wear resistance, and long working life, which is suitable for heavy duty grinding, the bearing shoes are precision ground, equipped with high quality spindle to provide excellent precision of 0.15μm.

KJ-4 alloy steel made spindle bearing, and three point hydrodynamic oil film system, to provide excellent cooling system cycles, high precision, and long working life.(New add)

AUTO LUBRICATION SYSTEM

The Auto lubricator provides lubrication to GW & RW spindle.

The centralized lubrication system lubricates all the slide-ways of upper/bottom slide and dressing arrangement slides, to ensure precision of feeding and processing.

Safety lock is equipped with Spindle motor, the lock will be auto-turned on when oil pressure lower than regulated value, provide protection to spindle.

Hydraulic oil fan to keep suitable oil temperature, which protects spindle away from thermal deformation, and extends oil seal’s working life.

Feed Screw

The feed Screw is made from Nickel alloy steel (SNCM-4), with normalization, high frequency harden treatment and precision ground to ensure high precision feeding;

The adjustable nut features smooth adjustment, high accuracy, and excellent wear resistance.

SLIDEWAYS

Double "∧" shaped slide-ways support bottom slide’s stable and accurate movement;

The slide-ways are hardened and precision ground to get smooth movement and excellent wear resistance;

Dust entering proof.

0.001mm feeding accuracy.

RESTRICT QUALITY INSPECTION

Henfux Q.C. department equipped with high precision inspection instruments, to provide fully inspection in each process and final product precision;

Restrict quality control to ensure each machine’s high precision.
