Rajlaxmi (A Brand Of Rolex Enterprise)

The Rajlaxmi (Rolex Enterprise) 2HP 3-Phase finishing machine with a Variable Speed Drive (VFD) panel is a specialized industrial setup. For orthopedic implants (such as knee, hip, or dental implants), finishing is a critical process requiring high precision and the ability to handle sensitive materials like Titanium or Stainless Steel (316L).

The addition of the VFD (Variable Speed Drive) Panel is the most vital component for this application, as it allows the operator to adjust the RPM to prevent overheating or "burning" the metal of the implant.

The control panel is designed to provide the delicate touch needed for medical-grade finishing:

• Speed Control: A potentiometer (knob) on the panel allows for "stepless" speed adjustment.

• Soft Start/Stop: Prevents sudden jerks that could damage an expensive orthopedic implant.

• Digital Display: Shows real-time RPM or Frequency ($Hz$), ensuring repeatability for quality control.

• Direction Switch: Allows for Forward/Reverse rotation, which is often necessary for multi-directional polishing of complex implant geometries.

• Emergency Stop: Industrial-grade push button for immediate shutdown.

Orthopedic finishing requires a different approach than standard industrial grinding:

• Material Compatibility: Designed to work with Satin/Mirror Finish mops and wheels to reach the "Ra" (surface roughness) values required for medical implants.

• Heat Control: Implants like Titanium can be damaged by high friction. The VFD allows for low-speed high-torque polishing to maintain material integrity.

• Vibration-Free: The heavy cast iron body and four-bearing spindle (optional but recommended) ensure there is no "chatter" on the surface of the implant, which could lead to surgical failure.

For implant finishing, this machine is typically used with:

•  Abrasive Belts: (50x2000mm) for initial deburring of cast implants.¹

   

• Buffing Wheels: Cotton or flannel mops for achieving a mirror finish.

• Dust Extraction: Mandatory for orthopedic work to remove hazardous fine metal dust from the workspace.

Rajlaxmi (Rolex Enterprise) offers a versatile range of Heavy Duty Pedestal Polishers, scaling from 0.5 HP for precision work to 10 HP for massive industrial applications. When equipped with an integrated Dust Collector System, these machines become a complete workstation for metal finishing, jewelry, automotive parts, and foundries.

The specifications vary by motor power to accommodate different wheel sizes and work intensities.

For heavy-duty polishing, the dust collector is not just an add-on; it is a safety necessity.

• Dual Suction Hoods: Specially designed hoods surround the polishing mops/wheels to catch fine lint, metal dust, and abrasive compound.

• Secondary Blower Motor: Usually powered by an independent motor (0.5 HP or 1 HP) to ensure consistent suction even when the polisher is under heavy load.

• Multi-Stage Filtration: Includes a collection bag or bin where heavier metal particles settle, while finer dust is trapped by the filter.

• Operator Safety: Specifically designed to prevent "Black Lung" and keep the workspace compliant with industrial health standards.

• Four Bearing System: In the 5 HP to 10 HP range, Rajlaxmi uses a specialized four-bearing spindle. This allows the machine to run for 12–16 hours daily without overheating or losing balance.

• Vibration Damping: The heavy pedestal base is hollowed and designed to be filled with sand or bolted to the floor, ensuring that even at 2800 RPM, the machine remains "dead still."

• CRNO Stamping: The motors use Cold Rolled Non-Oriented steel stampings, which reduce electrical losses and prevent the motor from heating up during continuous polishing.

• 0.5 HP – 1 HP: Ideal for jewelry, small brass parts, and surgical instruments.

• 2 HP – 5 HP: Best for automotive bumpers, hardware, and kitchenware polishing.

• 7.5 HP – 10 HP: Used for heavy casting foundries, large pipe polishing, and industrial die finishing.

• VFD Panel: For variable speed control (essential for delicate materials like Titanium).

• Extended Spindles: Extra-long shafts to polish deep-dish items or large hollowware.

• Tapered Spindles: For quick changing of cotton buffing mops.
