Product Overview
The HJY-4GT is a manual vertical turret milling machine built around a vertically adjustable knee, cross-moving saddle and long T-slot table. This layout gives machinists direct control over X, Y and Z positioning for general milling, drilling, boring and repair work without the setup overhead of a CNC machining center.
A swiveling and tilting turret head allows the spindle to approach angled surfaces and awkward features. The 16-step speed range supports different cutter diameters and materials, while the configured three-axis DRO helps the operator track table and knee position during manual machining.
This configuration is intended for workshops that need flexibility across prototypes, fixtures, maintenance parts and short production runs. Final machine selection should be based on workpiece size, material, tolerances, tooling, site power and the exact accessory scope written into the quotation.

Seven Product Advantages
Advantage 1
Precision Ball-Screw Drive
Supports smooth axis movement and more controlled manual positioning with reduced transmission clearance.
Advantage 2
Rigid Milling Head
A reinforced head and motor mounting structure provide a stable platform for general milling, drilling and boring.
Advantage 3
Integrated Control Panel
Machine controls and the digital position display are grouped within easy reach of the operator.
Advantage 4
Automatic Lubrication
The electronic lubrication system supplies oil to key sliding and transmission points at set intervals.
Advantage 5
Retractable Front Guard
The front table guard helps contain chips while retaining practical access for setup and maintenance.
Advantage 6
Double-Wall Machine Body
The reinforced column and base structure are designed to improve rigidity during everyday workshop machining.
Advantage 7
Electric Z-Axis Lift
Powered knee elevation reduces manual effort when adjusting the table height for different workpieces and fixtures.
Standard and Optional Configuration
The following table separates the base machine from the options recorded for this HJY-4GT configuration. The final supply scope should always be confirmed in the signed quotation.
| Item | Supply Status | Details |
|---|---|---|
| Base machine | Standard | HJY-4GT knee-type body, turret head, table and manual axis controls |
| Spindle taper | Selection required | R8 reference configuration; confirm NT30 availability before ordering |
| Digital readout | Configured option | Three-axis DRO upgrade shown in the supplied order list |
| Y-axis power feed | Configured option | Powered cross-feed unit for controlled table movement |
| Pneumatic tool change | Configured option | Confirm spindle taper, drawbar system and required air pressure |
| Electric Z-axis lift | Configured option | Powered knee elevation for easier height adjustment |
| Export packing | Optional | Timber export packing according to destination and shipping method |
Typical Applications
- Toolroom milling and maintenance work
- Flat-surface and shoulder milling
- Slots, keyways and groove machining
- Drilling, boring and reaming operations
- Fixtures, jigs and repair components
- Prototype and one-off metal parts
- Small-batch machining in general workshops
- Die, mold and machine-component preparation
Actual machining capability depends on material, cutter, setup rigidity, feed, depth of cut and required tolerance.
Configuration and Selection Notes
Confirm whether the quotation is for an R8 spindle or NT30 configuration. Tool holders, collets and pneumatic drawbar components must match the selected spindle system; they should not be treated as interchangeable accessories.
The listed 80-5440 rpm range should be checked against destination frequency and motor configuration. Voltage, phase, electrical components, DRO brand, power-feed brand, guarding and conformity documents should all be confirmed in writing.
Published travel and table-load figures describe machine capacity, not guaranteed finished-part accuracy. Buyers with close tolerances should define an acceptance method, measuring equipment and sample machining requirement before shipment.
