Choose quality machine vise given the variety of products and models on the market, it can be quite difficult. Even high cost is not in all cases an indicator of product quality. Let us consider in more detail what parameters and characteristics you should pay attention to when choosing in order to choose really high-quality products that meet the standards.
What is a machine vice
Machine-made vices are usually flat, and are placed directly under the working tool of the machine, whether it be a drill chuck or a milling cutter clamp. They are used to fix workpieces in the desired position and provide the possibility of precise processing of products.
What distinguishes quality equipment
Quality machine vices have several important features that are mandatory for each model:
- The smooth surface of the jaws, the absence of defects - the quality and strong fixation of the workpieces between them directly depends on how well the vise jaws are made;
- Smooth movement of the clamping part of the jaws - as a rule, movement is carried out using a threaded screw. It should ensure uniform movement of the jaws without distortions and uneven distribution of clamping load;
- Strength of fixation on the surface - the platform of the vise has several holes for fastening to the table or the surface of the table of the machine tool, fastening is carried out with screws or bolts, the diameter of which depends on the mass of the vise. When fixing, uniform pressing should be ensured.
These parameters and requirements are basic for all models of bench vise.
Which is better, steel or cast iron?
For the manufacture of a vise, cast iron or steel is usually used. Cast iron products are more affordable. If the work is not performed often, you can give preference to products made of ordinary gray cast iron. If you need a more professional tool within a reasonable budget, then you should give preference to round graphite cast iron.
If you are not limited in your budget and want to purchase the highest quality equipment, then you should give preference to a vise made of high-quality alloy steel, using chromium and other inclusions that provide increased rigidity, strength and wear resistance of the alloy. carbide cutters and other expensive but high-quality tools.
