Performance characteristics The operation table of the machine tool has three directions of feed longitudinal, horizontal and rotary, thus, workpiece when undergoes clamping offering machining of several surfaces. The machine follows hydraulic transmission mechanism with sliding pillow reciprocating movement and hydraulic feed system for working table. The sliding pillow maintains the same speed in each operation and the speed of ram and table can be adjusted as per requirement. Ram commutation oil present in hydraulic control table is used for oil reversing, besides to hydraulic and manual feed outer. Even a single motor drive can work in vertical, horizontal and rotary motions at high speeds. Hydraulic feed is used when the operation is turning back to instantaneous feed, thus it is better than mechanical slotting device.

The versatility of light duty slotting machine is another aspect that can be used to produce every type of shape, irrespective of size of the component, grooves, keyways, splines, exterior and interior splines and more. We are a precision slotter manufacturer who design machine for workshops and industries that demand versatility and speed to produce these types of parts.

Excellent cutting power: Fortunately by the innovative features and radical method of working with tools, there is no material or groove that is hard to machine with Daljit slotting machine.

Versatile slotting machine with several advantagesMaximum precision: Daljit slotting machine ensures accurate performance and unprecedented precision. It doesn’t need a skilled operator

Slotting machine for every type of workshop: We manufacture a wide range of slotters for every tye of industry with automatic rotary indexing and CNC control for clients looking for the maximum production rates.

What is a slotting machine or Slotter:Slotting machine is a reciprocating device tool in which, a ram handling the tool reciprocates in a vertical axis and the cutting by tool is performed during the downward hit. The machine tool removes any unnecessary material chips from the workpiece to produce splines, grooves and other tools. The machine can also produce flat and contour surface and slots. Components of slotter machine include: Base, column and table, ram and tool head and saddle.

The revolutionary vertical slotting machine by Daljit is currently considered to be the most versatile machine in the market. It uses an innovative and patented system to produce discreet slots, offering excellent precision and speed than other standard machine.

Base of slotter is robust enough to handle any of the cutting forces. The front side of the vertical column has guide directions for tool. Ram supports the tool head to which tool is connected. Workpiece is installed on table that can undergo longitudinal, cross and rotary feed motion. Daljit Slotting machine is commonly used to cut grooves, key and create slots in different shapes producing uniform and non-uniform surfaces. It can be used on any work where vertical tool motion is considered important and beneficial.

Maximum efficiency: Slotter machine works with the actual width of the groove to be machined. It offers complete precision and high speed for the maximum productivity.

Abstract: Carbon fiber-reinforced polymer (CFRP) composites have gradually replaced metals due to their exceptional strength-to-weight ratio compared to metallic materials. However, the drilling process often reveals various defects, such as surface roughness, influenced by different drilling parameters. This study explores the drilling quality of uni-directional CFRP composites, as well as hybrid Al2O3 alumina and hybrid SiC silicon carbide nano-composites, through experimental exploration using step, core, and twist drills. Response surface methodology (RSM) and statistical tools, including main effect plots, ANOVA, contour plots, and optimization techniques, were used to analyze the surface roughness of the hole. Optimization plots were drawn for optimal conditions, suggesting a spindle speed of 1500 rpm, feed of 0.01 mm/rev, and a 4 mm drill diameter for achieving minimum surface roughness. Furthermore, two machine learning models, artificial neural network (ANN) and random forest (RF), were used for predictive analysis. The findings revealed the robust predictive capabilities of both models, with RF demonstrating superior performance over ANN and RSM. Through visual comparisons and error analyses, more insights were gained into model accuracy and potential avenues for improvement.
