Compatible EROWA 4 in1 CNC D100 Pneumatic Chuck ER-155102

The JWGRIP Compatible EROWA 4 in1 D100 Pneumatic Chuck ER-155102 is designed for CNC machining centers where operators need a compact, multifunction fixture to reduce idle time.Instead of managing separate locating pins, clamps and air lines, this D100 pneumatic chuck combines four functions in one body: precise locating, firm clamping, quick pallet release and pneumatic open/close control.

It is directly compatible with the D100 chuck system interface, so you can keep using your existing pallets and holders without changing the current fixture layout.

Because the clamp opens and closes by compressed air, it can also be integrated into automated CNC cells controlled by machine IO signals. A full stainless body resists coolant corrosion, making it suitable for wet machining environments.

What is the 4 in 1 D100 Pneumatic Chuck

“4 in 1”means that one D100 pneumatic chuck body performs four workholding functions that normally require separate components: ① locating the pallet at a fixed zero point, ② clamping the pallet firmly during machining, ③ releasing the pallet quickly for changeover, ④ opening or closing by compressed-air control for automation. The

"D100" refers to the chuck system interface series it is compatible with, widely used on CNC machining centers. The zero-point design means every pallet returns to the same coordinate after each change, so multi-cavity and batch parts keep consistent dimensions without repeated manual alignment.

Core Advantages

1.All-in-one design: locating, clamping, release and air control in a single compact body saves machine-table space.

2.Pneumatic operation：opens and closes by compressed air, enabling robot or machine-IO automation.

3.≤2μm repeat accuracy：stable datum for multi-cavity and batch CNC production.

4.D100 system compatibility：works with existing D100 pallets and holders without rework.

5.Corrosion-resistant stainless body：reliable under coolant-rich wet machining.

6.Fewer wearing parts：simplified structure lowers maintenance frequency compared with multi-component clamps.

Technical Specifications

Selection Guide

Before ordering the JWGRIP Compatible EROWA 4 in1 D100 Pneumatic Chuck , please confirm the following points.

1.Confirm your machine uses the D100 chuck system interface; D100 differs from ITS100 / ITS50 series and cannot be cross-matched.

2.Confirm a stable 6-bar compressed-air supply. If your workshop has no air source, choose a manual version instead.

3.Confirm installation space and air-port direction according to your machine-table layout.

4.Verify the reference part number ER-155102. If your existing spare part carries a different ER number, jump to the matching variant page to avoid a wrong purchase.

5.If you plan automation, confirm your machine controller can provide an IO signal to drive the air valve.

Application scenarios

The Compatible EROWA 4 in 1 CNC D100 Pneumatic Chuck ER-155102 is widely used on CNC machining centers, milling cells and automated workholding lines where operators need fast and repeatable pallet changeover. Typical jobs include mold base machining, electrode and Fixture trayization , and multi-cavity batch production where every pallet must return to the same zero point after each change.

Because the chuck opens and closes by compressed air, it fits production cells that already run robot loading or machine-IO control. Many of our customers mount the chuck on a standard D100 pallet fixture and execute the same program across a set of pre-clamped pallets. This shortens non-cutting time, keeps part dimensions consistent from batch to batch, and reduces the manual alignment that ordinary clamps still require.

Working Principle & Materials

This D100 pneumatic chuck works on a zero-point locating principle. A hardened locating structure on the chuck body receives the mating element of the pallet, and an internal spring mechanism keeps the pallet clamped. When compressed air is applied, the clamp releases and the pallet can be swapped in seconds.

The term D100 refers to the chuck system interface series this unit is compatible with, which is widely applied on CNC machining centers and EDM equipment. The main body is machined from stainless steel, which resists coolant corrosion and keeps locating surfaces stable in wet machining environments.

The simplified internal structure uses fewer wearing parts than multi-component clamps, so daily maintenance is easier and the chuck holds its repeat positioning accuracy over a long service life. We also offer customized base plates and multi-station assemblies for customers who need a complete workholding solution.

Why Choose JWGRIP

JWGRIP is a professional CNC workholding manufacturer, so buyers deal directly with the factory when ordering the Compatible EROWA 4 in 1 D100 Pneumatic Chuck . We support factory-direct and OEM service, and each chuck ships with a factory inspection certificate and a 12-month limited warranty. Compared with ordinary multi-component clamping assemblies, this 4-in-1 pneumatic chuck integrates locating, clamping, quick release and air control in one body, which saves machine-table space and lowers maintenance cost. Our in-house engineering team provides free pre-sales technical advice on air-port layout and automation IO connection, helping you confirm the right D100 interface variant before you place an order.

Packaging & After-sales

Each chuck is wrapped with anti-rust paper and packed in a custom carton with foam padding for safe international shipping; the manual and factory inspection certificate are enclosed. Stock items ship within 1-2 working days after payment, and out-of-stock bulk orders are scheduled by our sales team.

We offer a 12-month limited warranty covering manufacturing defects, excluding damage from improper air-pressure supply, collision, over-load or man-made disassembly.If goods arrive with damage, leakage or out-of-tolerance accuracy, please send photos and test data within 7 working days for our technical review.

FAQ

Q1: Can the JWGRIP Compatible EROWA 4 in1 D100 Pneumatic Chuck be used with ITS100 pallets?

A1: No. This chuck uses the D100 system interface, which is a different series from ITS100. Please match it with D100 pallets and holders only.

Q2: What does “4 in 1” actually mean?

A2: One body performs four functions,locating, clamping, quick release and pneumatic open/close control, replacing several separate fixture components and saving table space.

Q3: Can I automate this chuck with my CNC controller?

A3: Yes. Connect an air valve and drive it with an IO signal from your controller to open and close the chuck automatically. Confirm your controller provides the required signal output.

Q4: What should I do if air leakage occurs?

A4: First check air pressure does not exceed 7 bar, then inspect sealing rings and air ports for chips or wear. Contact our after-sales team if leakage persists.

Q5: How do I confirm it fits my machine?

A5: Send photos of your current chuck, pallet and machine-table dimension to our sales; our engineering team will give free technical advice.
