Grinding Example

Work Piece: Lubrication pump parts

Model: JHD-3205 Double Spindle (OD&ID) Grinding Machine

OD of Workpiece: Ø320mm (Ø12.5”)

Length of Workpiece: 200mm(Ø 7.8”)

Diameter of Center Hole: Ø6~200mm

High machine stability and precisely engineered structure

Precision guaranteed and multiple grinding solutions

Numerical control for grinding cycle, easy operation

Applications: Automobile / Motor / Transportation parts; Energy industry; Precision machine tool components; Air/Hydraulic components; Precision measuring instruments; Electronic industry; Optical instruments


Box type base construction features superior stability and rigidity.

Adapt hydrostatic guide way system with fast movement, the feeding rate can reach 1000mm / minutes. Low noises and low vibration benefit which is better than box and linear guide ways.

With hollow hydraulic cooling system design on ball screw, to minimize thermal deformation as well to make sure machine positioning accuracy, good stability and longer using life.

Equipped Italian made built-in spindle of which with water cooling system for good stability. The maximum grinding wheel spindle speed is up to 3500RPM and able to carry OD Ø510mm grinding wheel.

The spindle could be CNC control automatic rotate ±30° for thread grinding.

JHT-4010 can equipped with our own develop “Smart Machine Function for reducing the deviation of manual tool setting. “ Smart Machine Function” can detect the properly grind timing. Further, to improve manufacturing process efficiency and obtain the best accuracy after grinding.

CNC controller with Fanuc 0i-TF, can equipped with industrial PC to raise up the calculation speed and improve “Human-Machine Interface(HMI)” interaction

JHT-4010 have a widely used which need highly precision machinery process, application such as: ball screw, general thread, spindle, T thread, worm.

Win the innovate award “Taiwan Excellent Awards 2020”
