Horizontal & Vertical Manual Operation Chuck ER-019424

What Is a Horizontal & Vertical Manual Operation Chuck?

A manual operation chuck is a workholding device that clamps a workpiece through manual tightening, without requiring pneumatic or hydraulic power. The Horizontal & Vertical version is designed to be mounted and used in both horizontal and vertical orientations, giving machining shops the flexibility to clamp workpieces on different machine types and setups. As a compatible replacement for the EROWA original part number ER-019424, it is manufactured to match the standard interface, so it engages with existing chucks and pallet systems.

The working principle is simple and reliable. The operator places the workpiece or fixture base into the chuck, then tightens it manually with a wrench or key. The clamping mechanism applies a stable, uniform holding force. Once clamped, the workpiece remains firmly positioned through the whole machining cycle and can be released quickly for the next part. The dual horizontal and vertical capability means the same chuck can serve multiple machines and setups, reducing the number of fixtures you need to purchase.

Material & Process Advantages

The chuck body is made of forged alloy steel and undergoes complete stress-relieving heat treatment to eliminate internal residual stress generated during machining. Many low-cost suppliers omit this critical step. If residual stress remains, repeated clamping and day-night temperature changes can cause microscopic deformation of the reference surfaces, leading to reduced positioning accuracy and shorter service life.

Every piece of raw material in our factory strictly completes the full annealing and stabilizing process, a standard derived from over ten years of practical engineering experience across numerous CNC fixture and automation projects. The reference surfaces and clamping jaws are precision-ground to hold tight tolerances, and the wear-resistant surfaces are hardened and stabilized to ensure stable clamping force and long service life even after thousands of clamping cycles.

Core Advantages

1.Dual Horizontal and Vertical Mounting

The chuck is designed for both horizontal and vertical use, so the same unit can handle workpieces on different machines and setups. This flexibility reduces the number of fixtures you need and lowers overall tooling cost.

2.Manual Operation, No Extra Power Needed

Tightening is done manually with a wrench or key, so no pneumatic, hydraulic or electrical supply is required. This makes it simple to use, easy to maintain and ideal for single-piece and small-batch production.

3.High Quality Material, Stable and Durable

Made from premium hardened alloy steel with uniform hardness, the chuck delivers long service life and dependable clamping force under repeated use, a durable investment versus cheaper chucks that wear or deform quickly.

4.Tight Dimensional Tolerances

Reference surfaces and clamping jaws are precision-ground with strict tolerance control. Every chuck undergoes 100% full-item dimensional inspection before delivery, and each unit is shipped with an original inspection report that can be supplied for verification upon overseas buyers' request.

5.Stable Batch Supply and Competitive Factory Price

Standard sizes are often kept in stock for shorter delivery, and bulk orders are welcomed with stable quality and competitive factory price. Small sample orders are supported before mass production.

Why Choose JWGRIP

Many suppliers sell compatible chucks, but the real difference lies in what happens before the product reaches you. We are the actual manufacturer, not a trading company, and every step of production is controlled inside our own CNC-fixture workshop.

• Full in-house control of forging, heat treatment, precision grinding and inspection.
• Verified material and heat treatment to avoid the deformation and accuracy loss common with cheap chucks.
• Competitive factory price without middleman while keeping stable batch quality.
• Flexible MOQ and fast supply, with standard sizes often kept in stock.
• One-stop customization including jaw type, surface treatment and marking.
• Reliable after-sales with 12-month warranty, spare-part support and remote technical guidance.

Manufacturing Process

All chucks go through full-flow production including forging, CNC machining, heat treatment, precision grinding and inspection within our in-house CNC-fixture workshop, with no complete-unit OEM outsourcing.

Complete production workflow : alloy-steel forging, rough machining, stress-relief aging, semi-finishing, hardening and tempering, precision grinding of reference surfaces and jaws, dimensional inspection, hardness check, assembly and function test, surface treatment, final inspection, anti-rust protection, and export-grade packing.

Quality Control & Certifications

Mandatory pre-delivery inspection items for every unit: reference-surface flatness and parallelism test, clamping-surface dimensional check, hardness test, surface-finish check, and manual clamping function test. Each unit is delivered with a unique factory-inspection data sheet. Our factory holds ISO 9001 quality-management-system certification, and material certificates are available for key metal components. Third-party laboratory inspection designated by customers is acceptable.

Selection & Customization Guide

Firstly, confirm the required chuck size, clamping range and the EROWA-compatible interface to match your machine and workpiece.

Secondly, decide whether you need a standard chuck or a customized jaw type to fit your workpiece shape.

Thirdly, for heavy or large workpieces, provide the maximum workpiece weight and cutting load, and our technical staff will assess whether a reinforced version is required.

Installation & Usage Notes

Before mounting, clean the reference surfaces and clamping area to remove chips and oil. Fasten mounting screws strictly following the torque values specified in the manual; violent over-torque tightening is forbidden to avoid deformation. Clamp the workpiece firmly but within the rated clamping range, and never exceed the maximum load listed on the specification sheet, as overload causes permanent deformation and reduces positioning accuracy. Clean the clamping surfaces with compressed air at every shift change to maintain stable clamping.

Packing, Lead Time & After-sales Service

Export-grade shock-proof solid-wood packing cases with thick foam inner buffer protection are adopted to safeguard precision surfaces during long-distance ocean shipping. Standard lead time is 10–15 days, and certain standard items are kept in stock for shorter delivery.

A 12-month full-unit warranty covers manufacturing defects not caused by human mis-operation, with free repair or spare-part replacement provided. Remote online technical guidance for installation and usage is available. Customized modification service is supported, and free samples are available for customer evaluation, with freight cost undertaken by buyers.

FAQ

Q1: What is the difference between this manual chuck and a pneumatic or hydraulic chuck?

A1: A manual chuck is tightened by hand with a wrench or key and needs no compressed air or hydraulic power, making it simpler, cheaper and easier to maintain, ideal for single-piece and small-batch work. Pneumatic and hydraulic chucks offer automation but require a power supply and extra accessories.

Q2: Can the same chuck be used for both horizontal and vertical setups?

A2: Yes, the chuck is designed for dual horizontal and vertical mounting, so one unit can serve different machines and setups, reducing the number of fixtures you need to purchase.

Q3: What steel grade and hardness is the chuck made of?

A3: The chuck body and jaws are made of high-grade hardened alloy steel with uniform hardness. The critical reference and clamping surfaces are precision-ground after heat treatment and retain full hardness for long service life.

Q4: How compatible is the chuck with the original EROWA system, and is it interchangeable across batches?

A4: The interface and dimensions are manufactured to match the EROWA original standard. Every batch is produced under the same fixtures, gauges and process parameters, and each unit is dimensionally inspected before delivery, so chucks are interchangeable within and across batches.

Q5: What is the maximum clamping capacity, and can I get a customized jaw?

A5: The chuck is rated for the clamping range of the standard model. For heavy or unusually shaped workpieces, provide the maximum workpiece weight and shape, and we can supply a customized jaw type to suit your application.
