What information do you need to quote a custom hydraulic cylinder?

Send bore diameter, rod diameter, stroke, retracted (pin-to-pin) length, working pressure, single- or double-acting design, mounting type at both ends, port size and thread standard, operating environment and estimated annual quantity. A drawing, a sample or a photo of the original nameplate shortens the quotation process.

Can you reproduce an OEM replacement cylinder from a sample?

Yes. Our engineers measure the sample, prepare a technical drawing and send it for your confirmation before machining starts, so interchangeability is agreed in writing before production.

Which standards do your parts and tooling follow?

We machine to the customer drawing in metric or imperial units. Typical references include ISO 6H thread tolerance for hydraulic cylinder nuts, DIN 69872 and JIS B6339 for CNC retention knobs, and ER collet systems for milling tool holders.

Do you supply hydraulic cylinder components separately?

Yes. We supply cylinder heads, pistons, nuts, flanges, bases, integrated barrels, bushings and spherical bearings, as well as hydraulic valve blocks, for cylinder builders and repair workshops.

How are export orders packed and shipped?

Goods are packed with standard export materials to prevent transit damage and shipped by sea, air or express courier according to your preference, with tracking information provided.

How quickly will I receive a reply?

Our sales engineers reply to email enquiries within 24 hours. You can also reach the team directly by phone or WhatsApp.

ZQ83 Single And Double Action Vise Wholesale Precision CNC Milling Machine Clamping Tools Direct Manufacturer Supplier Factory

Product Description

ZQ83 Single & Double Vise shares a similar structure with the ZQ80 Vise, comprising components such as a fixed vise body, a movable vise body, a lead screw, and a positioning device, among others. In function, it boasts its own advantages as below:

1) High Precision

The use of high-quality materials and advanced manufacturing processes ensures the high precision and stability of the flat jaw pliers.

2) Large Opening

It can hold workpieces in both directions or in one direction. Bidirectional holding provides two positioning references for the jaws, allowing multiple workpieces to be held simultaneously to reduce positioning errors.

3) High Cost Performance

The price is relatively low with high cost performance, making it highly suitable for various processing applications.

Material: High-quality alloy steel, hardness of working surface: HRC58-62
Parallelism: 0.005mm/100mm | Perpendicularity: 0.005mm

Key Features

✓ 1. Flexible clamping method
✓ 2. High positioning accuracy
✓ 3. Compact and concise structure
✓ 4. Sturdy and durable construction

Technical Specifications

Jaw Width: Typically ranges between 100mm and 200mm
Jaw Height: Usually between 30mm and 65mm

Frequently Asked Questions (FAQ)

Q1: What is the main difference between single-action and double-action ZQ83 vises?

A: Single-action models hold workpieces in one direction, while double-action models feature bidirectional holding (two positioning references) to clamp multiple parts simultaneously, reducing positioning errors.

Q2: What material and hardness specifications are used for the ZQ83 series?

A: The vise is crafted from high-quality alloy steel, with working surface hardness treated to HRC58-62 for high wear resistance and durability.

Q3: What precision standards can this vise maintain during operation?

A: The ZQ83 series offers high precision with a parallelism of 0.005mm per 100mm and perpendicularity maintained within 0.005mm.

Q4: Can custom sizes or designs be manufactured?

A: Yes, OEM and ODM manufacturing services are supported. Custom products can be developed based on your technical drawings if standard minimum order requirements are met.

Q5: Which machining equipment is compatible with this vise?

A: The ZQ83 is widely used across CNC milling machines, drilling machines, precision surface grinders, and general workbench fitting tasks.
