Discover a range of metal slotting machines available for purchase in China, featuring competitive prices and top-notch quality. Shanquan Machinery, a trusted slotting machine manufacturer and supplier, is dedicated to effectively meeting your specific machining needs. Our vertical keyway slotting machines are designed to deliver precision and efficiency.


Metal cutting machine tools are essential for processing slot features. During operation, the workpiece moves longitudinally, horizontally or rotationally, and the slotting cutter moves up and down to cut the workpiece. This linear motion machine tool uses the vertical reciprocating motion of the slotting cutter to create keyways and holes. The worktable of the keyway slotting machine is integrated with the bed. The tool bar extends upward from the bed through the workpiece hole, enabling the slotting cutter to perform intermittent feed motion without being restricted by a column. This design makes it ideal for processing keyways in large parts, such as propellers.

Mastering the Art of Metal Slotting Machine: Tips and Tricks

(I) Mechanical slotting machine:

1. Before the idling test run or after adjusting the ram (plug) stroke, turn the flywheel by hand to check whether the ram reciprocating motion is good and whether the ram stroke meets the requirements. After confirming that it is normal, the machine tool can be started for test run or formal operation.

2. The ram stroke and speed are not allowed to be adjusted during operation.

3. After operation, lift the plug to the head and move the rotary table to the middle position of the guide rail.


(II) Hydraulic slotting machine:

1. The ram stroke is not allowed to be adjusted during operation.

2. After operation, put the ram plug at the bottom.

Working Principle of Slotting Machine

The metal slotting machine, essentially a vertical planer, shares a similar structural principle with shapers. Its primary motion involves the linear reciprocating action of the slotting cutter along the ram in the vertical direction. Meanwhile, the feed motion allows for intermittent movement of the workpiece in longitudinal, transverse, and circumferential directions.


The surface roughness (Ra) achievable with the metal slotting machine ranges from 6.3 to 1.6 microns, while the verticality of the machined surface is maintained at an impressive 0.025 mm over 300 mm. The primary parameter of the metal slotting machine is the maximum slotting length, which determines the longest cut that the machine can make in a single operation.


If you are looking to buy a slotting machine in China, you’ll find a variety of options available from reputable slotting machine manufacturers and suppliers. Whether you need a keyway slotting machine or a versatile vertical slotting machine, there are numerous choices to fit your requirements. When considering your investment, it’s essential to compare slotting machine costs and prices to ensure you find the best value for your specific applications.
