Qh80 machine vise

Types of qh80 machine vises

A machine vise is an indispensable piece of equipment in workshops and industrial settings. A machine vise is designed to hold down objects while they are being worked on by cutting tools and other related equipment. There are several types of machine vises, each of which is customized to provide a specific feature for use with a specific type of machine.

• Universal Machine Vise: A universal machine vise 80mm is structured to hold objects at different angles when mounted on a supporting surface. The feature that allows for angular adjustments makes this machine vise compatible with machines such as milling machines. An upside-down cut on the object helps to know if the object is upside down or not. Also, universal vises may have a split or hinged design that helps to position the cut object better.
• Fixed Machine Vise: This type of machine vise is commonly found on band saws. Fixed machine vises have a movable jaw that allows objects of different sizes to be held in place firmly. The adjustable feature is not present in a universal machine vise. While a universal machine vise can hold objects with different angular positions, a fixed machine vise is limited to holding objects in only one position.
• Cross Solve Vise: Also called the ''crisscross jaw machine vise'', this type of machine vise is a workhorse of any machining environment. As suggested by the name, this vise features two sets of jaw sets, one horizontal and one vertical, that work to hold an object firmly in either axis. A feature of jaw stripping later facilitates adjustment on uniformity of jaw stripping.
• Rotary Vise: For cylindrical objects like pipes or rods, a forms vise suits these types of objects. It features an adjustable jaw that can move inward to hold down cylindrical objects. Rotary machine vises, as the name suggests, can only hold cylindrical with circular cross-sections. Closed slots in jaws help grip and support objects that have a jig, not a cavity.
• Dovetail Vise: This machine vise features an object-holding system that looks similar to an open ''V''. Git machines use this type of machine vise to hold objects firmly while cutting and related work is being carried out. This includes cutting grooves and channels closely resembling a ''V'' shape. Another area where this machine vise is used is in photographic equipment, whereby a camera is placed on a moving platform that is connected to a machine vise.

Specifications and maintenance of the machine vise

The specifications for a machine vise differ based on the model and style. However, some general specifications can help customers narrow down their choices when buying the machine vise.

• Jaw Width: The jaw width indicates how wide the jaws open to hold workpieces. It ranges from 6 to 8 inches. A wider jaw width provides flexibility in working with larger pieces, but this also affects the overall size of the vise.
• Jaw Opening: The jaw opening measures how far the jaws can open from each other. As stated earlier, the jaw opening ranges from 6 to 8 inches. It is directly proportional to the jaw width. Large jaw openings allow the machine to accommodate thicker and bigger workpieces.
• Weight: The weight of a machine vise ranges from 15 kg to 66 kg. Overall, heavier machine vises provide stability when working on hard metal workpieces. However, they are not portable. A portable machine vise may not be heavy, but it provides ease of use and resilience for light-duty work.
• Clamping Force: The clamping force is the amount of force used to clamp a workpiece. The force is measured in pounds or kilograms, and a machine vise with larger jaws and size generates a greater clamping force. According to research, a larger machine vise can generate up to 2,000 lbs of clamping force with a torque of 400 ft-lbs.
• Material: The most common material for a machine vise is cast iron or aluminum. A combination of materials like aluminum and steel is also used to make the jaws of the machine vise. This is to provide a strong gripping force on the workpiece.

With the right cleaning tools and supplies, customers can easily and safely clean their machine vise to maintain its function and performance. Start by inspecting the tool to see if any parts are missing or damaged. Dust and debris should be removed with compressed air or a brush. A wire brush with a long handle is a great option because it helps clean hard-to-reach areas and surfaces of the machine vise.

Next, use a soft cloth and some lubricant to wipe down and coat the moving parts of the vise, like the screw threads. This helps remove any gunk or dirt buildup that may have accumulated while using the machine. Continue the wipe-down process by using a clean cloth to remove excess lubricant from the tool. Cleaning the lubricant off the machine is important to prevent a build-up of dirt and debris.

If the machine vise has any hard-to-reach parts, a circular brush or putty knife can be used to clean them. Once done, it is best to store the machine in a covered or enclosed space or area to prevent further dirt accumulation.
