Electric tapping machine
Commonly known as electric tapping arms, are specialized shop tools used to quickly and precisely cut internal threads into metal, plastic, or composite workpieces.
✅Powered by highly controllable servo or brushless DC motors.
✅Torque Overload Protection: Smart torque-limiting collets .
✅Depth Control & Deep Hole Pecking: Program precise depth limits for blind holes; the arm automatically reverses when the target depth is hit. "Pecking" or deep hole cycles periodically back out to break chips and clear swarf.
✅Universal Workheads: Articulating workheads can pivot 360 degrees.

Milling Machine T-Slot Covers (Chip Guards)In machine shops, flexible silicone rubber strips are pressed directly into the table's T-slots.
❤️Prevent hot metal shavings, swarf, and debris from packed grooves, drastically reducing cleanup times.
❤️Material: Typically made from high-temperature silicone rubber (often Shore 70A hardness) to withstand red-hot metal chips and resist cutting coolants.
❤️Common Sizes: Standard table widths like 9/16" (14mm), 5/8" (16mm), and 11/16"(18mm)

A VDI test bar (or alignment arbor) is a high-precision calibration tool built to DIN 69880 standards used to inspect, align, and test the runout and concentricity of CNC lathe turrets and spindle interfaces.
❤️They help prevent accelerated tool wear and part scrapping caused by misaligned tooling pockets, especially after a machine crash.
❤️Precision: Certified runout tolerances down to 0.003 mm (3 microns) or better.
❤️Inclusions: Every arbor ships with a aluminum case and formal calibration certificate.

Our hydraulic holders excel at high-precision finishing operations, high-speed machining (balanced up to 25,000+ RPM), and applications requiring strict dimensional control.
*Ultra-Low Runout: They consistently deliver a Total Indicated Runout (T.I.R.) of ≤ 3 microns (0.0001"). This prevents uneven wing wear and keeps cuts precise.
*Vibration Dampening: The internal reservoir of hydraulic oil acts as a natural shock absorber. This eliminates chatter, protects the machine spindle, and extends tool life.
*High Clamping Torque: Uniform pressure delivers massive holding power—frequently around 650 Nm or greater—preventing axial tool slippage.

Our XD20/XD20S automatic end mill grinding machine (or CNC end mill sharpener) re-sharpens worn cutting edges or manufactures new solid carbide and high-speed steel (HSS) end mills. Restoring cutting angles (primary relief, secondary clearance, gash angle, and end teeth) extends tool life and lowers tooling costs.

*Portable Desktop Sharpeners (Semi-Auto / Guided): Compact units using ER collets and preset fixture ports. The operator manually rotates or slides the tool through guided stops while the motor maintains grinding wheel contact. Ideal for quick shop-floor re-sharpening (typically 2-flute, 3-flute, and 4-flute end mills from 4mm to 20mm).

*Multi-Axis CNC Tool Grinders (Fully Automatic): Industrial 4-axis or 5-axis CNC machines (e.g., ANCA, Walter, Rollomatic, Makino) that automatically probe, regrind, or manufacture complex geometries, including variable helix angles, ball-nose profiles, and corner radiuses.

Our automatic end mill grinding machines are fully automated CNC sharpeners engineered to restore the primary/secondary clearance angles, end faces, and flutes of worn cutting tools without requiring a highly skilled manual technician.
Modern industrial units feature touchscreen control interfaces, electronic index heads, and integrated liquid cooling systems to deliver consistent tool geometries and prevent burning.
Fast & Precise End Mill Machinery ZD-X20S
High-volume automatic tool maintenance shopsCapabilities: Grinds 4mm–20mm tools; restores flat end mills, ball noses, and chamfers in 1–2 minutes.

A hydraulic vise is a precision workholding device that utilizes pressurized hydraulic fluid to generate an exceptionally powerful, stable, and repeatable clamping force.
Unlike traditional manual options that rely on mechanical lead screws, these systems use oil pressure to multiply input force.
This makes them an industry standard for heavy-duty CNC machining, high-precision milling, and automated manufacturing lines.
Key Advantages over Other VisesHigh Clamping Force: Easily delivers multiple tons of pressure, outperforming standard mechanical and compressible pneumatic setups.
Extreme Repeatability: Eradicates the variance of human operators, ensuring identical holding pressure for every single part cycle.
Automation Ready: Integrates seamlessly with robotic arms and CNC controllers for hands-free loading and unloading.
Adjustable Pressure: Operators can dial the pressure down to secure delicate, thin-walled parts without crushing them.
Reduced Operator Fatigue: Clamps and releases in less than a second with the push of a button or foot pedal.

In heavy industrial manufacturing, an angle head is a specialized mill accessory. It allows a standard vertical CNC milling machine to perform cutting, drilling, or slotting operations horizontally or at distinct angles without needing to completely unclamp and reposition the heavy metal workpiece.
