Variable PCD Drilling Machine
This machine is used to drill in various PCD named as Variable Pitch Circle Diameter (PCD), PCD from 0 mm to 1200 mm (47") and drill size maximum to 32mm (1 1/4"). Components like flanges, Brake drums, motor end covers, Valve bodies, and disc brakes etc... Which has small and medium batch quantity can be done very cost effectively.
Reason for developing
Through our experiences in the market, we found people are using expensive VMC for these operations. There are components in small and medium batch quantities. Lot of companies are facing problem on delivering components on time. They are using expensive VMC and very high skilled labor to meet target, finally they spend more money and the production cost goes up very high. All this will be replaced by this low cast machine. an unskilled labor can also start working in 2or 3days training. Thus you can cut down the cost by 30 - 50% approximately.
Basic function of machine
Same as all VMC, this machine head fixed in vertical column, which has up and down Z-axis movement through LM guide ways with Ball Screws with single spindle.
The slide is fixed in the base for X-axis movement. Hydraulic Indexing Table is mounted in the slide. The slide movement towards and away from the column generates X-axis. With the Digital Read out (DRO), the PCD can be varied as required very easily.
Basic & Types of machines
The basic machine consists of following and function will not differ.
- Machine Base
- The head, spindle drive by motor
- Vertical column (Hydraulic / Servo) drive for Z-axis movement
- Indexing table Hydraulic drive
- Cross slide for X-axis to vary PCD. Mechanical drive with DRO to set PCD (DRO optional)
